The handle 200 can be easily attached to the small water receiving portion 120 of the toilet seat body 100 by engaging with the engaging recess 130 (see FIG. 6) of the portion 120. At this time, the engagement protrusion 230 of the handle 200 has a triangular prism shape, and the engagement recess 130 also has a triangle in top view, so that the handle 200 can be attached to the small water receiver 120 without rattling in the circumferential direction. Can do.

  Next, the support shaft 330 (see FIG. 9) of the cap 300 is fitted into the shaft hole 232 (see FIG. 7) of the handle 200, and the cap 300 is easily fixed to the handle 200 via bolts, washers, and spring washers. be able to.

  When the infant does not need the handle 200 to a certain extent, the infant's auxiliary toilet seat 1 is used with the bolt 300 loosened, the cap 300 removed, the cap 300 being attached after the handle 200 is removed (FIG. 10). reference). When attaching the cap 300, the support shaft 330 (see FIG. 9) of the cap 300 is fitted into the shaft hole 140 (see FIG. 6) of the small water receiving portion 120, and the cap 300 is connected via a bolt, a washer, and a spring washer. Can be easily fixed to the small water receiver 120.

  As described above, after attaching the handle 200 and the cap 300 according to the usage mode of the infant, or after removing the handle 200 and attaching only the cap 300, the auxiliary toilet seat 1 for infants is attached to the adult toilet seat in the following procedure. Place without wobbling. When attaching such an infant toilet seat 1 to an adult toilet seat, the width of the inner circumference of the toilet seat body of the adult toilet seat is intended in advance. Then, the amount of protrusion of the movable member 550 from the case 510 is determined such that the distance between both end portions of the movable members of the attachment adjusting fixture 500 is slightly smaller than the width of the short diameter. Then, as shown in FIG. 15, the protrusion 561 of the movable member 550 is fitted into the concave groove 521 of the case 510 corresponding to the protruding amount, and in this state, the wall portion of the case 510 is shown in FIGS. The side opening 511 is engaged with the positioning ribs 150 a and 150 b of the wall portion 150 of the infant auxiliary toilet seat 1, and the lower surface side opening 512 of the case 510 is brought into contact with the toilet seat main body lower surface 101. Then, as shown in FIG. 17, the attachment adjustment fixture 500 is attached to the toilet seat body 100 using screws 355, spring washers 356, and washers 357.

  Next, the infant's auxiliary toilet seat 1 in which the protruding amount of the movable member 550 is matched to the adult toilet seat is placed on the adult toilet seat as shown in FIGS.

  When placed in this manner, the rear end contact rib 151 and the side wall surface 554 of the movable member 550 in the left and right attachment adjustment fixture 500 are in contact with the inner periphery of the adult toilet seat or at a certain distance. Since the width of the inner periphery of the adult toilet seat becomes narrower toward the front side of the place where the side wall surface 554 contacts or is located at a certain distance, the auxiliary toilet seat 1 for infants shifts toward the front of the adult toilet seat. In addition, the rear end contact rib 151 contacts the rear end of the inner periphery of the adult toilet seat, so that it does not shift backward. As a result, rattling of the infant auxiliary toilet seat 1 in the adult toilet seat is prevented. Further, rattling in the left-right direction (width direction) is prevented by the left and right side wall surfaces 554. In this way, the infant auxiliary toilet seat 1 placed on the adult toilet seat is placed on the adult toilet seat with little attachment by the mounting adjustment fixture 500.

  The wall portion 150 of the toilet seat body 100 and the case are in close contact with each other without any gap, and the lower surface 101 of the toilet seat body and the upper edge of the case 510 are in close contact with each other via the auxiliary cover ribs 101a and 101b. Yes. Further, there is no gap between the case 510 and the movable member 550 or between the toilet seat main body lower surface 101 and the movable member 550 without any gap. That is, no matter what the amount of protrusion of the movable member 550 is selected, the case 510 is always in close contact with the toilet seat main body lower surface 101 and the wall portion 150 and no gap is formed between them, There is no entry.

  Further, since the protrusion 561 of the movable member 550 is formed on the base end side, and the concave groove 521 of the case 510 is formed on the inner wall thereof, no matter how the movable member 550 protrudes, The outer surface of the case 510 is formed as a smooth surface, so that it is difficult for dirt to adhere to it, and even if dirt adheres, it can be easily cleaned. Therefore, like the conventional infant toilet seat described in Patent Document 1, dirt adheres to the guide groove of the fixed piece between the fixed piece and the wall or through the opening of the mounting portion, and cannot be removed even by cleaning. This does not cause a problem.

  Thus, the outer surface of the mounting adjustment fixture 500 is not formed with irregularities on the surface as in the conventional mounting adjustment fixture, and is formed smoothly over the entire surface, so that dirt is less likely to adhere to it. Even if filth adheres, it can be easily cleaned and removed. In addition, since there is no gap between the case 510 and the wall portion 150, there is no entry of dirt between the case 510 and the wall portion 150. Therefore, it is possible to avoid a situation in which the filth enters the concavo-convex portion and adheres by drying as in the prior art, which is undesirable in terms of appearance and hygiene.

  As described above, the infant's auxiliary toilet seat 1 according to the present embodiment has the attachment adjustment fixture 500 for the adult toilet seat, and the case 510 of the attachment adjustment fixture 500 has an inner wall portion and an upper end. Is in contact with the outer side surface of the wall portion 150 of the infant auxiliary toilet seat 1 and the lower surface of the toilet seat portion and is detachably fixed. In addition, the movable member 550 can be moved in and out of the case 510 and the amount of protrusion can be variably accommodated. Note that the case 510 and the movable member 550 are attached in a state in which the case 510 and the movable member 550 are in close contact with the lower surface of the toilet seat body 100 and the wall 150 via fasteners such as screws.

  Thus, since the protrusion amount of the movable member 550 is variable, the infant's auxiliary toilet seat 1 can be adapted to adult toilet seats of various sizes. In addition, since the case 510 contacts the lower surface of the infant auxiliary toilet seat 1 and the outer surface of the wall portion, even when the mounting position of the movable member 550 is changed when the infant auxiliary toilet seat is placed on the adult toilet seat, the wall portion The structure is such that no gap is generated between the case 150 and the case 510, and the cleanability is good. Further, even if the movable member 550 is protruded, there is no gap between the attachment adjusting fixture 500 and the wall portion 150 so that dirt enters, so that the dirt adheres between the attachment adjusting fixture 500 and the wall portion 150. Can be prevented and hygienic.
