The plate surface of the base portion 71 is directed vertically, and has a horizontal plane extending in the horizontal direction. The base portion 71 is formed with a hanging portion 73 extending downward from the inner peripheral portion thereof. The hanging portion 73 projects downward from the entire inner circumference of the base portion 71 and is formed in an annular shape. At the lower end (free end) of the hanging portion 73, an opening 72 is formed so as to penetrate the inside cover 70 in the thickness direction (vertical direction). The base portion 71 corresponds to a “covering portion” that covers the upper part of the sealing device 40. The opening area of the opening 72 is larger than that of the opening 30a of the toilet seat 30.

The hanging portion 73 is integrally molded with the base portion 71, and the lower portion is inclined inward with respect to the upper portion. Specifically, the hanging portion 73 has a front side portion 74 and a rear side portion 75, which are connected by a continuous surface in the front-rear direction. Of the entire circumferential direction of the opening 72, the front portion 74 is provided on the front side of the center point O of the opening 72, and the rear portion 75 is provided on the rear side of the center point O. The front side portion 74 has an inclined surface 74a inclined inward in the upper portion thereof, and has a curved surface 74b bent inward so as to be convex downward at the lower end portion. The hanging portion 73 may be provided at a position slightly away from the inner edge of the opening 72.

The rear side portion 75 has an upper inclined surface 75a and a lower inclined surface 75b, which are connected in an arc shape. The upper inclined surface 75a and the lower inclined surface 75b are inclined inward. The inclination of the upper inclined surface 75a with respect to the vertical direction is larger than that of the lower inclined surface 75b, and the inclination is gentle. On the other hand, the inclination of the lower inclined surface 75b with respect to the vertical direction is larger than or substantially the same as that of the inclined surface 74a of the front portion 74. Looking at the front side portion 74 and the rear side portion 75 of the hanging portion 73 as a whole, the front side portion 74 has a smaller inclination in the vertical direction than the rear side portion 75, and has a steep inclination. A curved surface 75c bent inward so as to be convex downward is provided in the lower portion of the rear portion 75.

A standing wall 76 that rises upward is provided on the outer edge of the base portion 71. The standing wall 76 is continuously provided in the circumferential direction over the entire outer edge portion of the base portion 71. The standing wall 76 has an upright plate portion 76a that stands up upward, and a horizontal plate portion 76b that extends outward from the upper part of the upright plate portion 76a. The upright plate portion 76a is inclined inward so that urine is easily received on the upper surface of the base portion 71 (see FIG. 7). The inclination of the upright plate portion 76a with respect to the vertical direction is substantially the same as the inclination of the front side portion 74. Such a standing wall 76 prevents the urine from leaking to the outside of the inside cover 70 even when urine spills on the upper surface of the base portion 71.

At least the rear portion of the horizontal plate portion 76b (that is, the outer edge portion of the inside cover 70) has a shape and size corresponding to the outer wall 35 (see FIG. 6). Specifically, in the horizontal plate portion 76b, the right corner portion 77 on the rear side has a linear shape corresponding to the vertical plane 35e, and the left corner portion 78 on the rear side has an arc shape corresponding to the curved surface 35f. .. As a result, the rear portion of the horizontal plate portion 76b and the rear portion of the outer wall 35 function as a positioning portion for arranging the inside cover 70 at a predetermined position with respect to the receiving plate 31 as a whole. Further, the inside cover 70 has a left-right asymmetric shape in a plan view. Therefore, when the inside cover 70 is installed upside down, the inside cover 70 is not positioned with respect to the receiving plate 31, and when the front and back are installed correctly, the inside cover 70 is placed on the receiving plate 31. Positioned against.

The lower surface of the horizontal plate portion 76b is a contact surface that comes into contact with the upper surface 35 g of the outer wall 35 when the inside cover 70 is installed on the receiving plate 31. When the lower surface of the horizontal plate portion 76b is in contact with the upper surface 35g of the outer wall 35, the inside cover 70 is supported by the receiving plate 31 (see FIG. 8).

The outer side wall 35 is provided with a recessed portion 35i recessed outward from the inner end portion on the upper surface 35 g thereof (see FIG. 3). Further, the standing wall 76 is provided with a recessed portion 76c recessed outward so as to be fitted inside the recessed portion 35i at a position corresponding to the recessed portion 35i (see FIGS. 2 and 6). The recessed portions 35i and 76c are provided on both the left and right sides, respectively, and are arranged at the same positions when viewed in the front-rear direction. When the inside cover 70 is installed on the receiving plate 31, the inside cover 70 is placed on the upper surface 35 g so that the recessed portions 35i and 76c fit each other. As a result, the front, rear, left and right positions where the inside cover 70 is attached are correctly positioned, and the inside cover 70 can be installed at an appropriate position in order to exert the urine infiltration prevention function. Further, when the inside cover 70 is installed on the receiving plate 31, the recessed portions 35i and 76c are kept in a fitted state, so that the displacement of the inside cover 70 is suppressed.

The outer edge of the inside cover 70 is provided with a notch 79 recessed inward. The notch 79 has a rectangular shape and is formed at the front corners on both the left and right sides. The shape of the notch 79 is not limited to a rectangular shape, and may be, for example, an arc shape. When viewed in a plan view, the outside of the notch 79 is arranged above the groove 36 (see FIG. 2). As a result, the inside cover 70 can be easily removed by lifting the periphery of the notch 79 with a finger. Further, the groove portion 36 can be visually recognized by peeping from above the notch portion 79. Therefore, the state (for example, color) of urine collected in the groove 36 can be confirmed with the inside cover 70 attached.

<Action of inside cover 70>
Next, the operation of the inside cover 70 will be described with reference to FIG. Note that FIG. 8 shows a vertical sectional view of the portable toilet 10 in a state where the toilet seat 30 is lowered in FIG. Further, in FIG. 8, the tubular film F attached to the sealing device 40 is shown by a chain double-dashed line.

As described above, the portable toilet 10 is provided with an inside cover 70 between the sealing device 40 and the toilet seat 30. At least the lower portion of the hanging portion 73 of the inside cover 70 is inserted into the inside of the opening 41 of the sealing device 40, that is, the opening P of the tubular film F. Further, in the hanging portion 73, at least a part of the lower surface of the portion that has entered the opening P is placed on the upper portion of the guide portion 42 (more specifically, the upper surface of the flange portion 47) via the film F. It is in contact. As a result, at least a part of the hanging portion 73 is in contact with the inner peripheral surface of the tubular film F mounted on the sealing device 40. In the present embodiment, the lower surface of the lower end portion of the hanging portion 73 (that is, the lower surfaces of the curved surfaces 74b and 75c) is in surface contact with the inner peripheral surface of the tubular film F.

Here, the urine W excreted from the user may scatter forward. In such urine W, the hanging portion 73 and the inner peripheral surface of the film F are in contact with each other below the upper end portion of the sealing device 40, so that the urine W can infiltrate further forward at the contact portion. It is suppressed. In this way, in the above-mentioned water blocking structure, the urine W scattered forward can be prevented from leaking to the outside from the upper part of the tubular film F.

Further, the inside cover 70 is formed of an elastic member, and the hanging portion 73 is elastically deformable. Therefore, due to the elastic force of the hanging portion 73, the hanging portion 73 can be brought into close contact with the inner peripheral surface of the tubular film F mounted on the sealing device 40. Further, since the hanging portion 73 is elastically deformable, the movement of the film F is less likely to be hindered when the tubular film F is fed from the outside to the inside of the guide portion 42 in the longitudinal direction of the film. The arrow D in FIG. 8 indicates the delivery direction of the film F. As a result, the infiltration of urine into the sealing device 40 can be sufficiently suppressed while not hindering the delivery of the film F. The hanging portion 73 corresponds to the “entry portion”, and the curved surfaces 74b and 75c correspond to the “surface contact portion”.

<Structure of front plate portion 24>
Next, the configuration of the front plate portion 24 will be described in detail. The front plate portion 24 has an upper plate portion 81 and a lower plate portion 82 arranged vertically. The upper plate portion 81 and the lower plate portion 82 are made of separate members.

The upper plate portion 81 has a long wall plate 68 extending in the left-right direction. The wall plate 68 is arranged so that the plate surface is directed to the front and back and the plate surface extends in the vertical direction. The left and right ends of the upper plate portion 81 are connected to the left plate portion 26 and the right plate portion 27 via a connecting plate (not shown), respectively. Specifically, the connecting plate has a long shape extending in the vertical direction, and the plate surface is oriented in the horizontal direction. Of the pair of plate surfaces of the connecting plate, the outer plate surface is adhered to the inner plate surfaces of the left plate portion 26 and the right plate portion 27, and the front end surface is adhered to the back surface of the upper plate portion 81. It is glued. As a result, the upper plate portion 81 is supported by the left plate portion 26 and the right plate portion 27.

A mounting plate 69 is connected to the lower end of the wall plate 68. In the present embodiment, the wall plate 68 and the mounting plate 69 form the upper plate portion 81, and the mounting plate 69 constitutes the lower portion of the upper plate portion 81. The mounting plate 69 is positioned so that the plate surface is oriented vertically and extends in the horizontal direction, and its front end surface is flush with the front surface of the wall plate 68. The rear portion of the mounting plate 69 projects rearward from the back surface (that is, the rear surface) of the wall plate 68, and the front portion of the outer plate portion 45 of the sealing device 40 is mounted on the upper surface of the protruding portion. As a result, while supporting the sealing device 40 inside the toilet body 20, the formation of wasted space on the front side inside the toilet body is suppressed as much as possible, and the portable toilet 10 is made compact.

Recessed grooves 97 and 98 extending in the left-right direction are formed on the lower surface of the wall plate 68 and the upper surface of the mounting plate 69 at positions facing each other. The concave groove 97 formed on the lower surface of the wall plate 68 is opened downward, and the concave groove 98 formed on the upper surface of the mounting plate 69 is opened upward. The upper end portion and the lower end portion of the connecting plate 83 extending in the left-right direction are fitted into the concave grooves 97 and 98, respectively. The wall plate 68 and the mounting plate 69 are fixed by adhesion or the like with the connecting plate 83 fitted in the concave grooves 97 and 98, respectively. Further, the vertical dimension of the connecting plate 83 is shorter than the total depth of the grooves of the concave grooves 97 and 98, and a gap 99 is formed between the upper surface of the concave groove 97 and the upper surface of the connecting plate 83. There is. As a result, even if there is a manufacturing error, a gap is not generated between the wall plate 68 and the mounting plate 69. Further, the wall plate 68 and the mounting plate 69 are adhered to each other, or the surfaces of the wall plate 68 and the mounting plate 69 are coated with, for example, polyurethane or the like, so that the wall plate 68 and the mounting plate 69 are between the wall plate 68 and the mounting plate 69. It is designed to prevent moisture from entering.

The lower plate portion 82 has a long wall plate 82a extending in the left-right direction, and is arranged with the plate surface facing the front-rear direction. The left and right ends of the lower plate portion 82 are connected to the left plate portion 26 and the right plate portion 27 via a connecting plate 90 (see FIG. 10), respectively. Specifically, the connecting plate has a long shape extending in the vertical direction, and the plate surface is oriented in the horizontal direction. Of the pair of plate surfaces of the connecting plate, the outer plate surface is adhered to the inner plate surfaces of the left plate portion 26 and the right plate portion 27, and the front end surface is adhered to the back surface of the lower plate portion 82. It is glued. As a result, the lower plate portion 82 is supported by the left plate portion 26 and the right plate portion 27.

The upper plate portion 81 and the lower plate portion 82 are arranged so that the lower plate portion 82 is recessed in the front-rear direction from the upper plate portion 81, and the front surface 86 of the upper plate portion 81 is the lower plate portion 82. It is located in front of the front surface 87. As shown in FIG. 9, the upper plate portion 81 and the lower plate portion 82 are arranged so that at least the upper end of the front surface 87 of the lower plate portion 82 is located in front of the rear surface 89 of the upper plate portion 81.

The upper plate portion 81 and the lower plate portion 82 have different front inclination angles. Specifically, in the upper plate portion 81, the plate surface of the wall plate 68 extends in the vertical direction, and the front surface 86 is in the vertical direction accordingly, whereas in the lower plate portion 82, the plate surface of the wall plate 82a is formed. (That is, the front surface 87) is inclined rearward with respect to the vertical direction. As a result, a sufficient space necessary for receiving the receiving plate 31 and the sealing device 40 is secured behind the upper plate portion 81 in the inside of the toilet body 20. On the other hand, the lower plate portion 82 only needs to be able to hide the front of the sealing device 40 and the like in relation to the inside of the toilet body 20, and the lower plate portion 82 has a degree of freedom in arrangement. Therefore, a wide space is secured in front of the lower plate portion 82 by inclining the plate surface of the lower plate portion 82 diagonally rearward.

Further, the front surface 86 of the upper plate portion 81 and the front surface 87 of the lower plate portion 82 are curved surfaces that are convex forward, and are located rearward from the center in the left-right direction toward both the left and right sides. As described above, in the front plate portion 24, the lower plate portion 82 is inclined rearward and the lower end portion is recessed, and the upper plate portion 81 and the lower plate portion 82 have a curved surface on the front surface. A large space is secured on both the left and right sides for the foot to touch the ground backward when the user stands up. Further, by forming the front plate portion 24 by arranging a plurality of plate materials (upper plate portion 81 and lower plate portion 82) vertically, both the upper plate portion 81 and the lower plate portion 82 are curved and lower. A complicated configuration such as tilting the side plate portion 82 rearward is realized. As shown in FIG. 10, the lower surface 84 of the upper plate portion 81 and the upper surface 85 of the lower plate portion 82 are bent so that the upper plate portion 81 and the lower plate portion 82 are convex forward with substantially the same curvature. As a result, the upper plate portion 81 and the lower plate portion 82 can be seen integrally, which is aesthetically pleasing.

Between the lower surface 84 of the upper plate portion 81 and the upper surface 85 of the lower plate portion 82, an overlapping portion in which the upper plate portion 81 and the lower plate portion 82 overlap each other is formed. Further, a gap 88 is formed in the overlapping portion. The gap 88 is a gap so narrow that a human finger cannot enter, and the width in the vertical direction is, for example, 5 mm or less. The gap 88 is so narrow that it seems that there is no gap 88 when viewed from the front or slightly obliquely. Therefore, it is difficult to see the inside of the toilet body 20, and the upper plate portion 81 and the lower plate portion 82 can be seen integrally. In the present embodiment, the upper end of the rear surface 91 of the lower plate portion 82 is located in front of the rear surface 92 of the mounting plate 69, and the entire upper surface 85 of the lower plate portion 82 is the lower surface 84 of the upper plate portion 81. (That is, it overlaps with the lower surface of the mounting plate 69) at the top and bottom.

As shown in FIG. 9, a groove portion 93 opened downward is provided on the lower surface 84 of the upper plate portion 81. The groove portion 93 extends in the left-right direction, and is provided along the curved shape of the front surface 86 over the entire area of the lower surface 84 in the left-right direction (see FIG. 10). The groove portion 93 has an upper base 94, a front wall 95 extending downward from the front end of the upper base 94, and a rear wall 96 extending downward from the rear end of the upper base 94. The front wall 95 and the rear wall 96 rise vertically from the lower surface 84 and are orthogonal to the lower surface 84.

Both the front wall 95 and the rear wall 96 are located in front of the front surface 87 of the lower plate portion 82. As a result, the groove portion 93 is formed at a position in front of the front surface 87 of the lower plate portion 82 of the lower surface 84 of the upper plate portion 81. In the present embodiment, in the upper plate portion 81 and the lower plate portion 82, a non-overlapping portion is formed in which the lower surface 84 of the upper plate portion 81 and the upper surface 85 of the lower plate portion 82 do not overlap vertically, and the non-overlapping portions thereof are formed. A groove portion 93 is arranged in the portion. The groove portion 93 is formed at an intermediate position (for example, the center in the front-rear direction) between the front surface 86 of the upper plate portion 81 and the front surface 87 of the lower plate portion 82. Therefore, the groove 93 is less noticeable from the outside of the portable toilet 10.

<Action of front plate 24>
Next, the flow of urine generated in the front plate portion 24 will be described with reference to FIG. The urine scattered while using the toilet and the urine dropped when the user stands up may flow down along the front surface 86 of the upper plate portion 81. Here, when the lower plate portion 82 of the front plate portion 24 is recessed from the upper plate portion 81 (see FIG. 9), the urine flowing down along the front surface 86 is behind the lower surface 84 of the upper plate portion 81. It becomes easier to get into the side. In particular, when the lower surface 84 of the upper plate portion 81 and the upper surface 85 of the lower plate portion 82 are vertically overlapped with each other, urine enters the gap 88 between the lower surface 84 and the upper surface 85, and urine also adheres to the upper surface 85. I will end up. Further, if the gap 88 is narrow (for example, if it is a narrow gap of 5 mm or less), the inside of the main body frame 22 becomes difficult to see, but urine easily enters the gap 88 due to the capillary phenomenon. Human fingers cannot enter such a narrow gap 88, and it is difficult to insert a cleaning tool. Therefore, it is difficult to remove the urine that has entered the inner surface of the lower surface 84 and the urine that has adhered to the upper surface 85 of the lower plate portion 82 by wiping. On the other hand, if urine is left attached to the main body frame 22, the odor of urine impairs comfort and lacks a sense of cleanliness. Further, when the main body frame 22 is made of wood, the main body frame 22 may be corroded.

In the portable toilet 10 of the present embodiment, the urine W adhering to the front surface 86 of the upper plate portion 81 flows down along the front surface 86 and wraps around from the lower end of the front surface 86 to the lower surface 84 as shown in FIG. , Dropped at the position of the front wall 95 of the groove 93. That is, the urine W flowing down along the front surface 86 is dropped by the groove portion 93 in front of the front surface 87 of the lower plate portion 82. In this way, in the above front structure, the urine W that has flowed down along the front surface 86 of the upper plate portion 81 is dropped onto the floor surface without entering between the upper plate portion 81 and the lower plate portion 82. Can be done. As a result, it is possible to prevent urine W from entering the inner surface of the lower surface 84 of the upper plate portion 81 and urine W from adhering to the upper surface 85 of the lower plate portion 82. The front plate portion 24 corresponds to the "shielding plate portion", and the groove portion 93 corresponds to the "draining portion".

It is not necessary that there is a visible gap 88 between the upper plate portion 81 and the lower plate portion 82. Even in this case, since there is an extremely narrow gap between the upper plate portion 81 and the lower plate portion 82 microscopically, a phenomenon in which water enters between the upper plate portion 81 and the lower plate portion 82 due to the capillary phenomenon. Can occur. Especially when there is no visible gap 88 between the upper plate portion 81 and the lower plate portion 82, unless the upper plate portion 81 and the lower plate portion 82 are disassembled, the upper plate portion 81 and the lower plate portion 82 The urine that got in between cannot be removed. In this regard, by providing the draining portion on the lower surface 84 of the upper plate portion 81, it is possible to prevent the odor of urine from impairing comfort or lacking a sense of cleanliness.

≪About bucket specifications≫
Next, the bucket specification portable toilet 10 will be described focusing on the differences from the automatic wrap specification. As shown in FIGS. 12 to 14, the bucket specification portable toilet 10 differs from the automatic wrap specification in that it includes a bucket 110 and a spacer 120, and does not include a sealing device 40 and an inside cover 70. On the other hand, in the bucket specification, the toilet body 20, the receiving plate 31, and the toilet seat 30 are members common to the automatic wrap specification. Description of these common members will be omitted.

<Bucket 110>
The bucket 110 is a container that receives the excrement of the user, and is a bottomed resin container with an open top. The bucket 110 is also referred to as a "filth receiver" or a "stool receiver". The bucket 110 includes a bucket body 112 for accommodating excrement. The bucket body 112 has a substantially cylindrical shape with an open upper portion, and has a shape in which the lower portion has a reduced diameter with respect to the upper portion. An opening 111 is formed by the upper end of the inner peripheral surface of the bucket body 112, and excrement is put into the inside of the bucket body 112 from the opening 111. A flange portion 113 is formed at the upper end portion of the bucket body 112 so as to project outward from the entire outer edge. The flange portion 113 has a horizontal plate portion 113a extending outward from the upper end portion of the bucket main body 112, and a folded portion 113b extending downward from the outer peripheral portion of the horizontal plate portion 113a (see FIG. 18). A tiltable handle 114 is attached to the folded-back portion 113b. The handle 114 is tilted backward when using the toilet and is arranged behind the bucket 110. A lid 115 covering the opening 111 is attached to the upper end of the bucket 110 from above (see FIG. 14).

<Spacer 120>
The spacer 120 is a resin plate-shaped member. The spacer 120 is attached to the receiving plate 31 and used when the portable toilet 10 is made into a bucket specification. When the spacer 120 is installed on the receiving plate 31, the spacer 120 supports the bucket 110 and positions the bucket 110 with respect to the toilet seat 30. The spacer 120 is detachably provided with respect to the receiving plate 31. In the following description of the spacer 120, as with the inside cover 70, unless otherwise specified, "front and back", "left and right", and "up and down" refer to the configuration of the spacer 120 installed in the portable toilet 10. It shall be.

As shown in FIG. 15, the spacer 120 includes a plate-shaped and annularly formed base portion 121. The plate surface of the base portion 121 is directed up and down, and has a horizontal plane extending in the horizontal direction. The base portion 121 is formed with a standing wall 123 extending upward from the inner peripheral portion of the base portion 121 along the inner edge portion of the opening 33 of the receiving plate 31. The standing wall 123 projects upward from the entire inner circumference of the base portion 121 and is formed in an annular shape. At the lower end (fixed end) of the standing wall 123, an opening 122 that penetrates the spacer 120 in the thickness direction (vertical direction) is formed. The opening 122 has a substantially circular shape corresponding to the outer circumference of the bucket 110, and the opening area thereof is smaller than the opening area of the opening 33 of the receiving plate 31 and larger than the opening area of the opening 111 of the bucket 110. It has become. Further, the inner diameter of the opening 122 is larger than the inner diameter of the opening 111 of the bucket 110 and smaller than the outer diameter of the flange 113.

The upper surface 121a of the base portion 121 is provided with an upper protrusion 124 that projects upward from the upper surface 121a. The upper protrusion 124 is provided on both the left and right sides, and is arranged at a position rearward from the center of the spacer 120. The upper protrusion 124 extends in the front-rear direction, and has an inclined surface 124a on the upper surface thereof whose rear portion is inclined upward with respect to the front portion (see FIG. 16).

The base portion 121 is formed with a folded-back portion 125 extending downward from the outer peripheral portion thereof. The folded-back portion 125 projects downward from the entire outer circumference of the base portion 121 and is formed in an annular shape. The lower surface 121b of the base portion 121 is provided with a lower protrusion 126 that projects downward from the lower surface 121b (see FIG. 17). The lower protrusion 126 is a protrusion, and a plurality of lower protrusions 126 are provided in the vicinity of the opening 122 in the base portion 121. In the present embodiment, a total of four are provided, one on each of the front and rear and the left and right of the lower surface 121b.

As shown in FIG. 18, the spacer 120 is supported by the receiving plate 31 by hooking the folded-back portion 125 on the inner side wall 34 of the receiving plate 31. In the state where the spacer 120 is supported by the receiving plate 31, the lower protrusion 126 is arranged inside the opening 33 of the receiving plate 31. As a result, the position of the spacer 120 with respect to the receiving plate 31 is positioned, and the displacement of the spacer 120 is suppressed in the state where the spacer 120 is installed.

The spacer 120 has a shape and size along the outer wall 35, at least at the rear. Specifically, in the spacer 120, the rear right corner portion 127 has a linear shape corresponding to the vertical plane 35e, and the rear left corner portion 128 has an arc shape corresponding to the curved surface 35f. As a result, the rear portion of the spacer 120 and the rear portion of the outer wall 35 function as a positioning portion for arranging the spacer 120 at a predetermined position with respect to the receiving plate 31 as a whole. The spacer 120 has a left-right asymmetric shape in a plan view. Therefore, when the spacer 120 is installed upside down, the spacer 120 is not positioned with respect to the receiving plate 31, and when the front and back are correctly installed, the spacer 120 is positioned with respect to the receiving plate 31. Will be done.

<Action of spacer 120>
Next, the action of the spacer 120 will be described with reference to FIGS. 18 and 19. When the film F is exhausted or when there is a power failure, the bucket 110 can be used as a toilet by using the bucket 110 instead of the sealing device 40 as the toilet receiving portion of the portable toilet 10. However, if the outer diameter of the bucket 110 is too small with respect to the opening 33 of the receiving plate 31, the outer peripheral portion of the bucket 110 cannot be hooked on the inner peripheral portion of the receiving plate 31. That is, the folded-back portion 113b at the upper end of the bucket is not located at the position X1 (that is, above the groove portion 36) where it can be hooked on the inner side wall 34 of the receiving plate 31, but is located at the position X2 inside it. .. In this case, the bucket 110 cannot be placed at a position where excrement can be received.

As described above, in the bucket-type portable toilet 10, the spacer 120 is attached to the receiving plate 31. With such a spacer 120, a standing wall 123 is newly provided inside the inner side wall 34, and the hooking position of the flange portion 113 is in the diameter reduction direction of the opening 33 of the receiving plate 31 (direction of arrow V in FIG. 19). It has been adjusted to. As a result, the spacer 120 can be supported by the receiving plate 31, and the bucket 110 can be supported by the spacer 120. Therefore, the bucket 110 is stably installed below the toilet seat 30, and the excrement can be received by the bucket 110. Further, since the folded-back portion 125 of the spacer 120 is engaged with the inner side wall 34 of the receiving plate 31, the positional deviation of the spacer 120 can be suppressed, and the state in which the bucket 110 is supported by the receiving plate 31 is maintained. The spacer 120 corresponds to the "position adjusting portion", and the standing wall 123 corresponds to the "engaging portion".

Also, when using the toilet, the handle 114 of the bucket 110 is tilted backward. At that time, the rear surface of the handle 114 tilted backward is brought into contact with the inclined surface 124a of the upper protrusion 124. As a result, the handle 114 can be prevented from entering the groove 36, and urine can be prevented from adhering to the handle 114.

According to the present embodiment described in detail above, the following excellent effects can be obtained.

In the front plate portion 24, the front surface 86 of the upper plate portion 81 and the front surface 87 of the lower plate portion 82 are curved surfaces that are convex forward, and the curved surfaces are positioned rearward as they move from the center in the left-right direction to both the left and right sides. The lower plate portion 82 was arranged at a position deeper than the upper plate portion 81, and the front surface 87 of the lower plate portion 82 was an inclined surface inclined rearward. As a result, it is possible to secure a wide space on both the left and right sides for the foot to be grounded backward when the user stands up, and the user seated in the portable toilet 10 can easily stand up.

It is difficult to realize a complicated structure in which both the upper plate portion 81 and the lower plate portion 82 are curved and the lower plate portion 82 is inclined rearward with a single wooden plate. In this respect, since the upper plate portion 81 and the lower plate portion 82 are separated to form the front plate portion 24, such a complicated structure can be easily formed even with wood.

The upper plate portion 81 and the lower plate portion 82 are arranged so that at least the upper portion of the front surface 87 of the lower plate portion 82 is located in front of the rear surface 89 of the upper plate portion 81. Therefore, it is difficult to see the inside of the toilet body 20 from between the upper plate portion 81 and the lower plate portion 82, and the front surface is smooth, which is aesthetically pleasing.

Since the groove portion 93 is provided at a position in front of the front surface 87 of the lower plate portion 82 of the lower surface 84 of the upper plate portion 81, the urine W flowing down along the front surface 86 of the upper plate portion 81 is dropped at the position of the groove portion 93. Can be done. As a result, even when the front plate portion 24 is formed separately from the upper plate portion 81 and the lower plate portion 82, it is possible to prevent urine from entering the lower surface back side of the upper plate portion 81. Further, even if the upper plate portion 81 and the lower plate portion 82 are overlapped vertically and a narrow gap 88 is formed between the upper plate portion 81 and the lower plate portion 82, it is difficult for urine to enter the gap 88. can do. Further, since the groove portion 93 is formed on the front side of the lower plate portion 82 with respect to the front surface 87, the groove portion 93 can be easily wiped and cleaned, and a clean state can be maintained.
