SUMMARY OF THE INVENTION The present invention was completed based on the above circumstances, and an object of the present invention is to suppress corrosion (electrical corrosion) of the surface of the door handle and the door body.

In order to solve the above-mentioned problems, a method for manufacturing a door for a storehouse according to the present invention includes a plate-shaped door main body covering an opening of a storage room of a storehouse, and a door main body provided on the surface of the door main body and made of metal. and a pair of non-conductive intervening members interposed between the door handle and the surface. In the method, the first sheet material attached to part of the first adhesive layer provided on the back surface of one of the pair of intervening members is peeled off from the part of the first adhesive layer. After that, a first attaching step of attaching the one intervening member to the surface via the part of the first adhesive layer; After peeling the second sheet material attached to part of the second adhesive layer provided on the back surface of the intervening member from the part of the second adhesive layer, remove the part of the second adhesive layer a second attaching step of attaching the other intervening member to the surface through the second attaching step; After peeling the attached third sheet material from the other part of the first adhesive layer and the other part of the second adhesive layer, the other part of the first adhesive layer and the other part of the second adhesive layer a third attaching step of contacting the door handle with the surface; and a third attaching step, which is performed after the third attaching step, and attaches to the door body portion in such a manner that each of the pair of intervening members overlaps each of the end portions of the door handle. and a door handle attaching step of attaching the door handle.

In the first attaching step, the second adhesive layer is covered with the second sheet material and the third sheet material, and both of the pair of intervening members are attached to the third sheet material. Therefore, only one of the pair of intervening members can be attached to the surface of the door main body while the positional relationship of the pair of intervening members is maintained by the third sheet member. Then, in the second attaching step, the other intervening member can be affixed to the surface of the door main body via a part of the second adhesive layer while maintaining the positional relationship between the pair of intervening members. In this manner, the pair of intervening members can be attached to the surface of the door main body while maintaining their mutual positional relationship. Then, in a third attaching step, the third sheet material is peeled off, and the remaining adhesive layers (the other part of the first adhesive layer and the other part of the second adhesive layer) of the pair of intervening members are attached to the surface of the door main body. After completing the attachment of the pair of intervening members in step (3), the door handle is attached to the door main body in the door handle attachment step. In the above method, the pair of intervening members can be attached to the surface of the door body while maintaining their mutual positional relationship. can be reliably intervened. Therefore, direct contact between the door handle and the surface (front surface) of the door body can be suppressed, and corrosion (electrical corrosion) of the surfaces of the door handle and the door body can be suppressed.

Further, in order to solve the above problems, the storage disclosed in the present application includes a box-shaped storage body that forms a storage chamber having an opening that opens forward, and a door that can open and close the storage chamber. , the door includes a plate-shaped door body covering the opening, and a metal door handle provided on a surface of the door body, wherein the surface is made of metal that constitutes the door handle. are made of different metals, and the door handle and the surface are in contact with each other via an intervening member having non-conductivity. The direct contact between the door handle and the surface (front surface) of the door body can be suppressed, and the corrosion (electrical corrosion) of the surfaces of the door handle and the door body can be suppressed.

Further, the surface of the door body may be made of stainless steel, and the door handle may be made of aluminum. Cost reduction can be achieved as compared with the case where the door handle is made of stainless steel. In addition, since aluminum has excellent workability, the shape of the door handle can be freely designed.

According to the present invention, it is possible to suppress the corrosion (electrical corrosion) of the surfaces of the door handle and the door body.

One embodiment of the present invention will be described with reference to FIGS. 1 to 18. FIG. In this embodiment, as shown in FIG. 1, a four-door cooling storage 10 is exemplified as the storage. As shown in FIGS. 1 and 2, the cooling storage 10 includes a box-shaped storage body 12 (insulating box body) forming a storage room 11, a machine room 14 provided above the storage body 12, and four doors 16 capable of opening and closing the storage room 11. - 特許庁The storage chamber 11 has an opening 11A that opens forward (to the left in FIG. 2) and is closed from the front by four doors 16. As shown in FIG. The storage body 12 is supported by legs 13 provided at the four corners of the bottom surface. A shelf board 17 is provided in the storage room 11 along the horizontal direction, and stored items stored in the storage room 11 can be placed on the shelf board 17 . A condenser 21 , a condenser fan 21 A, and a compressor 22 are accommodated in the machine room 14 while being mounted on a unit base 23 . Note that the horizontal direction in FIG. 1 is the horizontal direction of the cooling storage 10 . 2 is the front side of the cooling storage 10, and the right side is the rear side of the cooling storage 10. As shown in FIG.

A drain pan 24, which also serves as a cooling duct, is arranged in the upper part of the storage body 12 so as to slope downward toward the rear (right side in FIG. 2). Thereby, a cooler chamber 25 is formed between the unit base 23 and the drain pan 24 . In the cooler chamber 25 , a cooler 26 is arranged so as to be attached to the lower surface of the unit base 23 . The cooler 26 constitutes a cooling cycle together with the condenser 21 and the compressor 22 . The cooling cycle is mainly composed of a compressor 22, a condenser 21, a capillary tube (or an expansion valve) (not shown), and a cooler 26 that are circulatingly connected by refrigerant pipes. A refrigerant heavier than air, such as propane or isobutane, is enclosed in the refrigerant pipe. An internal fan 27 driven by a motor is provided on the front side of the drain pan 24 , and a cold air blowing section 28 is formed on the rear side of the drain pan 24 .

During the cooling operation, the compressor 22, the internal fan 27 and the condenser fan 21A are driven. By driving the internal fan 27, the air in the storage compartment 11 is sucked into the cooler compartment 25 as indicated by the arrow P1 in FIG. The cooled air is blown out from the blowout portion 28 into the storage chamber 11 as indicated by an arrow P2. As a result, cold air is circulated into the storage compartment 11 to cool the storage compartment 11 .

The four doors 16 are rotatably attached to the storage body 12 via hinges 18 at the side ends. Since the four doors 16 have the same basic configuration, the configuration of the door 16 will be described by exemplifying the upper right door 16 among the four doors 16 in the following description. As shown in FIGS. 3 and 4, the door 16 includes a plate-shaped door body 31 (see also FIG. 2) that covers the opening 11A, and a metal door body 31A (front face) provided on the surface 31A of the door body 31. a door handle 41, a pair of non-conductive intervening members 51 and 52 interposed between the door handle 41 and the surface 31A, a screw 32 for attaching the door handle 41 to the door main body 31, a door A cylindrical seal member 33 inserted through a through hole 31B (see FIG. 6) formed in the main body 31 and a cover member 34 (hole cap) covering the seal member 33 from behind are provided.

As shown in FIG. 6, the door main body 31 includes an exterior plate 60 and an interior plate 61 made of synthetic resin. The door main body portion 31 is formed in a box shape by an exterior plate 60 and an interior plate 61, and a heat insulating material 63 made of foamed resin (for example, hard polyurethane) is foam-filled in the inner hollow portion. The surface 31A of the door main body 31 is made of an exterior plate 60, and the exterior plate 60 is made of stainless steel (stainless steel), for example. Moreover, the door handle is made of, for example, aluminum. In other words, the surface 31A of the door main body 31 is made of stainless steel, and is made of a metal different from the metal of which the door handle 41 is made. In other words, the door handle 41 is made of metal different from the surface 31A. The rear surface of the door main body 31 (the rear surface, the surface on the side of the storage room 11) is composed of an interior plate 61. As shown in FIG.

The door handle 41 is elongated in the vertical direction, and has a curved shape in which the central portion in the vertical direction bulges forward (to the left in FIG. 6) when viewed from the side in FIG. End faces 41B, 41B on both sides in the longitudinal direction of the door handle 41 are opposed faces arranged to face the surface 31A. Further, the cross-sectional shape of the door handle 41 taken along a plane orthogonal to the longitudinal direction is, for example, a substantially elliptical shape. As shown in FIG. 5, the end face 41B has the same shape (substantially elliptical shape) as the cross section of the door handle 41 (the cross section taken along a plane perpendicular to the longitudinal direction). The door handle 41 is attached to the door main body 31 with screws 32 at both ends (in other words, upper end and lower end) in the longitudinal direction, more specifically at a pair of end faces 41B, 41B. In this embodiment, the longitudinal direction of the door handle 41 is exemplified along the vertical direction, but the installation posture of the door handle 41 is not limited to this. Alternatively, the longitudinal direction of the door handle 41 may be along the left-right direction (horizontal direction).

An end face 41B of the door handle 41 is formed with a threaded hole 41A into which the screw 32 is screwed. Insertion holes 65A and 66A through which the screws 32 can be inserted are formed in the exterior plate 60 at locations corresponding to the screw holes 41A, as shown in FIGS. Further, a reinforcing plate member 64 is provided on the rear surface of the exterior plate 60 at a portion overlapping with the door handle 41. The plate member 64 is formed with an insertion hole 64A through which the screw 32 can be inserted. ing.

As shown in FIG. 7, the intervening member 51 is interposed between the upper end (upper end surface 41B) of the door handle 41 and the surface 31A. is interposed between the lower end (lower end surface 41B) of the and the surface 31A. In other words, the door handle 41 and the surface 31A are in contact with each other via the intervening members 51,52. The intervening member 51 and the intervening member 52 are light-transmissive (transparent) synthetic resin films, and have non-conductivity (insulation). The intervening members 51 and 52 are made of polyester, for example, but are not limited to this, and may be made of polyethylene terephthalate (PET), for example. Note that the intervening members 51 and 52 are not limited to films, and may be block-shaped, for example.

As shown in FIGS. 3 and 5, the intervening member 51 and the intervening member 52 have a substantially elliptical shape that is one size larger than the shape of the end surface 41B of the door handle 41. As shown in FIGS. In addition, in FIG. 5, the intervening member 51 and the intervening member 52 are illustrated by two-dot chain lines. For example, the outer peripheral edges of the intervening members 51 and 52 are arranged outside the outer peripheral edge of the end surface 41B of the door handle 41 by several mm (for example, 2 mm) over the entire circumference. 18, the intervening member 51 and the intervening member 52 are attached to the surface 31A via adhesive layers 81 and 82. As shown in FIG. The intervening member 51 and the intervening member 52 have the same shape, and as shown in FIG. 12, the pair of intervening members 51 and 52 are arranged in a vertically symmetrical shape.

Further, as shown in FIG. 4, the intervening member 51 and the intervening member 52 respectively have insertion holes 51A and 52A through which the screws 32 can be inserted. Moreover, since the intervening member 51 and the intervening member 52 are transparent, they are hardly noticeable to the user of the cooling storage 10, and the deterioration of the design of the door 16 can be suppressed. In addition, the intervening member 51 and the intervening member 52 are not limited to being made of a transparent material, and may be made of the same color as the color of the surface 31A, for example. The insertion hole 51A is formed at a portion near the outer periphery of the interposed member 51 (the lower end portion in FIG. 12), and the insertion hole 52A is formed at a portion near the outer periphery of the interposed member 52 (the upper end portion in FIG. 12). It is

As shown in FIG. 6, the door main body portion 31 has a through hole 31B that penetrates both the interior plate 61 and the heat insulating material 63 in the front-rear direction. As shown in FIG. 7, the upper screw 32 is accommodated in the upper through hole 31B and is screwed through the insertion hole 64A and the insertion hole 65A into the screw hole 41A of the upper end surface 41B. . As shown in FIG. 8, the screw 32 on the lower side is screwed into the threaded hole 41A of the end face 41B on the lower side through the insertion hole 64A and the insertion hole 66A while being accommodated in the through hole 31B on the lower side. ing. For example, a caulking material 35 is interposed between the sealing member 33 and the lid member 34 . The sealing member 33 is made of, for example, foamed polystyrene or the like, and has flexibility and heat insulation. The lid member 34 has a box-like shape that opens forward and has a circular shape when viewed from the front.

Next, a method for manufacturing the door 16 (door for storage) will be described. The method of manufacturing the door 16 includes a door body portion manufacturing step of manufacturing the door body portion 31 by foaming and filling the heat insulating material 63 into the inside of the box formed by the exterior plate 60 and the interior plate 61, and the door body portion manufacturing step. A step of attaching a pair of intervening members 51 and 52 to the surface 31A of the door 31 (first to third attaching steps to be described later); And prepare.

In the intervening member attaching process of the present embodiment, a pair of intervening members 51 and 52 are attached using a longitudinal sheet 70 (mounting paper) shown in FIGS. 9 and 14 . As shown in FIG. 15, a first adhesive layer 81 is provided on the back surface of the intervening member 51 (the surface on the side of the front surface 31A, the surface on the side opposite to the door handle 41). It is attached to the sheet 70 (more specifically, the first sheet material 71 and the third sheet material 73) via the 81. As shown in FIG. A second adhesive layer 82 is provided on the back surface of the intervening member 52 (the surface on the side of the front surface 31A, the surface on the side opposite to the door handle 41). The intervening member 52 is attached to the sheet 70 (more specifically, the second sheet material 72 and the third sheet material 73) via the second adhesive layer 82. As shown in FIG. Note that the adhesive layers 81 and 82 are layers made of, for example, an adhesive, and have adhesiveness to each of the intervening members 51 and 52, the surface 31A, and the sheet 70. As shown in FIG.

A pair of intervening members 51 and 52 are arranged on the seat 70 in a positional relationship corresponding to both end portions (more specifically, both end surfaces 41B and 41B) of the door handle 41 . The spacing between the pair of intervening members 51 and 52 on the sheet 70 (see L1 in FIG. 9) is the same as the spacing between the pair of intervening members 51 and 52 on the surface 31A (see FIG. 5). The posture of the intervening members 51 and 52 on the sheet 70 is made to match the posture of the intervening members 51 and 52 on the surface 31A (predetermined pasting posture, see FIGS. 12 and 13). In this embodiment, as shown in FIGS. 9 and 12, the intervening members 51 and 52 are arranged on the sheet 70 (and thus on the surface 31A) so that the insertion holes 51A and 52A sides face each other. It is not limited to this.

The sheet 70 is made of, for example, paper (or synthetic resin), and more preferably, the contact surface with the intervening members 51 and 52 is coated with a release agent or the like. As shown in FIGS. 9 and 15, the sheet 70 is divided into three sheet members (first sheet member 71, second sheet member 72, and third sheet member 73) by slits 70A and 70B. More specifically, the sheet 70 is divided into a first sheet material 71 and a third sheet material 73 by a slit 70A, and divided into a second sheet material 72 and a third sheet material 73 by a slit 70B. The first sheet material 71 forms one end of the sheet 70 in the longitudinal direction, and the second sheet material 72 forms the other end of the sheet 70 in the longitudinal direction. The third sheet material 73 forms an intermediate portion of the sheet 70 in the longitudinal direction, and is arranged between the first sheet material 71 and the second sheet material 72 . It should be noted that the sheet 70 is more preferably flexible.

As shown in FIG. 15, the first sheet material 71 is attached to a portion 81A of the first adhesive layer 81 provided on the back surface of the intervening member 51 (one intervening member of the pair of intervening members). . The second sheet material 72 is attached to a portion 82A of the second adhesive layer 82 provided on the back surface of the intervening member 52 (the other intervening member of the pair of intervening members). The third sheet material 73 includes the other part 81B of the first adhesive layer 81 (the part not covered with the first sheet material 71) and the other part 82B of the second adhesive layer 82 (the part not covered with the second sheet material 72). part). In other words, the intervening member 51 is affixed over both the first sheet material 71 and the third sheet material 73 , and the intervening member 52 is affixed over both the second sheet material 72 and the third sheet material 73 . is pasted. Further, the third sheet material 73 has a through hole 73A formed at a portion overlapping with the insertion hole 51A, and a through hole 74A formed at a portion overlapping with the insertion hole 52A.

In the first attaching step that is performed after the door main body portion manufacturing step, as shown in FIGS. The intervening member 51 is adhered to the surface 31A via the part 81A of the adhesive layer 81 . More specifically, the operator moves the intervening members 51 and 52 so that the insertion hole 51A and the insertion hole 65A of the intervening member 51 overlap and the insertion hole 52A and the insertion hole 66A of the intervening member 52 overlap. While adjusting the position of , the intervening member 51 is attached to the surface 31A. In addition, in the first attaching step, since the other portion 81B of the first adhesive layer 81 is covered with the third sheet material 73, the other portion 81B does not come into contact with the surface 31A. That is, in the first attaching step, part of the intervening member 51 is attached to the surface 31A.

Also, in the first attaching step, the second adhesive layer 82 of the intervening member 52 is covered with the second sheet material 72 and the third sheet material 73, so the intervening member 52 does not stick to the surface 31A. Further, in the first attaching step, since the intervening members 51 and 52 are attached to the third sheet material 73, the positional relationship between the intervening members 51 and 52 is maintained. For this reason, the operator must attach the intervening members 51 and 52 to a predetermined sticking position (the position where the insertion hole 51A and the insertion hole 65A of the intervening member 51 overlap and the position where the insertion hole 52A and the insertion hole 66A of the intervening member 52 overlap). While adjusting the positions of the intervening members 51 and 52 so that the intervening member 51 is adhered to the surface 31A, the work of adhering the intervening member 51 can be easily performed.

Through holes 73A and 74A are formed in the third sheet member 73. As shown in FIG. For this reason, the operator can see the insertion hole 65A of the exterior plate 60 through the insertion hole 51A of the interposed member 51 to confirm that the insertion hole 51A and the insertion hole 65A overlap and that the insertion hole 52A of the interposed member 52 can be The intervening member 51 can be attached to the surface 31A while confirming that the insertion holes 52A and 66A overlap by looking at the insertion holes 66A of the exterior plate 60. FIG.

In the second attaching step performed after the first attaching step, as shown in FIGS. 11 and 17, the second sheet material 72 is peeled off from the portion 82A of the second adhesive layer 82, and then the exposed second adhesive layer is removed. Interposed member 52 is adhered to surface 31A through part 82A of layer 82 . In the second attaching step, the intermediate member 51 is partially attached to the surface 31</b>A, and the intermediate members 51 and 52 are connected by the third sheet member 73 . Therefore, the intervening member 52 can be reliably attached to a predetermined attachment position (the position where the insertion hole 52A and the insertion hole 66A overlap) on the surface 31A. In addition, in the second attaching step, the other portion 82B of the second adhesive layer 82 is covered with the third sheet material 73, so that the other portion 82B does not come into contact with the surface 31A. That is, in the second attaching step, part of the intervening member 52 is attached to the surface 31A.

In the third attaching step performed after the second attaching step, as shown in FIGS. After peeling off the third sheet material 73 from the other portion 81B of the first adhesive layer 81 and the other portion 82B of the second adhesive layer 82, the other portion 81B of the first adhesive layer 81 and the other portion 82B of the second adhesive layer 82 are removed. are attached in contact with the surface 31A. That is, in the third attaching step, the remaining portions of the intervening members 51 and 52 that were not attached in the first and second attaching steps are attached to the surface 31A. As a result, the entire back surface of the intervening member 51 is attached to the surface 31A via the first adhesive layer 81, and the entire back surface of the intervening member 52 is attached to the surface 31A via the second adhesive layer .

In the third attaching step, when the third sheet material 73 is peeled off, the third sheet material 73 may be peeled off from both the other portion 81B and the other portion 82B at once, but it is possible to peel off at once. If it is difficult, by cutting the third sheet material 73, a portion 73E (see FIG. 17) including a portion attached to the other portion 81B and a portion 73F including a portion attached to the other portion 82B can be formed. (See FIG. 17), and the portion 73E and the portion 73F may be individually peeled off.

6 and 13, in the door handle attaching step that is executed after the third sticking step, both end portions (both end surfaces 41B, 41B), the door handle 41 is attached to the door main body 31 using the screws 32, 32 in such a manner that they overlap each other. Specifically, as shown in FIG. 7, the upper end surface 41B of the door handle 41 and the intervening member 51 overlap each other, and as shown in FIG. Attach the door handle 41 in the form of

The upper screw 32 is inserted from the back side of the door body 31 through the through hole 31B, the through hole 64A, the through hole 65A, and the through hole 51A in this order, and then screwed into the upper screw hole 41A of the door handle 41. combined. Further, the lower screw 32 is inserted from the back side of the door body 31 through the through hole 31B, the through hole 64A, the through hole 66A, and the through hole 52A in this order, and then screwed into the lower screw hole 41A of the door handle 41. screwed into. The head portion of the screw 32 is configured to be engaged with the hole edge of the insertion hole 64A in the plate member 64 from behind (the right side in FIG. 7), for example.

After the step of attaching the door handle, the seal members 33 are inserted into the through holes 31B, and the caulking material 35 is applied to the rear surface of each seal member 33. Then, the cover member 34 is inserted into the through holes so as to cover the seal members 33 from the rear. 31B inside. As a result, the through hole 31B is closed by the lid member 34, and the manufacture of the door 16 is completed.

Next, the effects of this embodiment will be described. In the first attaching step, the second adhesive layer 82 is covered with the second sheet material 72 and the third sheet material 73, and both of the pair of intervening members 51 and 52 are attached to the third sheet material 73. It is in a state of Therefore, only the intervening member 51 can be attached to the surface 31</b>A of the door body 31 while the third sheet member 73 maintains the positional relationship between the pair of intervening members 51 and 52 . In the second attaching step, both the pair of intervening members 51 and 52 are attached to the third sheet material 73, so that the positional relationship (and attitude) of the pair of intervening members 51 and 52 is maintained. In this state, the intervening member 52 can be attached to the surface 31A of the door main body portion 31 via the portion 81A of the second adhesive layer 82 . In this manner, the pair of intervening members 51 and 52 can be attached to the surface 31A of the door body 31 while maintaining their positional relationship. That is, the pair of intervening members 51 and 52 can be attached at predetermined attachment positions on the surface 31A in a predetermined attachment posture.

For example, when the intervening member 51 is attached without using the sheet 70, there is a concern that the intervening member 51 is attached at a position shifted from the predetermined attaching position. In addition, in the intervening member 51 having a substantially elliptical shape, the insertion hole 51A is arranged on the outer peripheral side of the center of the intervening member 51 . In this case, even if the insertion hole 51A and the insertion hole 65A are positioned so as to overlap each other, the intervening member 51 is stuck in a posture inclined in one of the left and right directions (corresponding to the left and right direction in FIG. 13). The situation is of concern. If the intervening member 51 is attached at an angle, there is concern that part of the end surface 41B may contact the surface 31A without being covered with the intervening member 51 . In this regard, in the sticking method using the sheet 70, since the positions and postures of the intervening members 51 and 52 are fixed on the sheet 70, the intervening members 51 and 52 can be reliably placed at predetermined sticking positions and in predetermined sticking postures. Can be pasted.

Then, the third sheet material 73 is peeled off in the third attaching step, and the remaining adhesive layers (the other portion 81B of the first adhesive layer 81 and the other portion 82B of the second adhesive layer 82) of the pair of intervening members 51 and 52 are attached to the door. After the pair of intervening members 51 and 52 are attached to the front surface 31A of the body portion 31, the door handle 41 is attached to the door body portion 31 in the door handle attachment step. In the above method, the pair of intervening members 51 and 52 can be attached to the surface 31A of the door main body 31 while maintaining their mutual positional relationship. Interposed members 51 and 52 having non-conductivity can be reliably interposed between surface 31A. As a result, direct contact between the door handle 41 and the surface 31A (front surface) of the door main body 31 can be suppressed, and corrosion (electrical corrosion) of the door handle 41 and the surface 31A of the door main body 31 can be suppressed. be able to. That is, the sheet 70 (mainly the third sheet material 73) has a function of a jig for attaching the pair of intervening members 51 and 52 to predetermined attachment positions on the surface 31A in a predetermined attachment posture. there is

The surface 31A of the door body 31 is made of stainless steel, and the door handle 41 is made of aluminum. Cost reduction can be achieved as compared with the case where the door handle 41 is made of stainless steel. Further, since aluminum is excellent in workability, the shape of the door handle 41 can be freely designed.

Further, in the present embodiment, since the intervening members 51 and 52 are attached to the surface 31A of the door main body 31, electric corrosion can be suppressed. Electrolytic corrosion can be suppressed more easily than the method of suppressing electrical corrosion by applying a non-conductive paint to the surface 31A.

<Other embodiments>
The present invention is not limited to the embodiments explained by the above description and drawings, and the following embodiments are also included in the technical scope of the present invention.
(1) In the above-described embodiment, the storage is a cooling storage, but the storage is not limited to this. The invention can be applied to storage with door handles.
(2) The surface of the door body and the material of the door handle are not limited to those exemplified in the above embodiment. The surface of the door body and the door handle may be made of different metals.
(3) The shape of the door handle is not limited to those exemplified in the above embodiments, and can be changed as appropriate. For example, as shown in FIG. 19, the end faces 141B and 141C of the door handle 141 have a substantially rectangular shape (for example, a rectangular shape with R-shaped corners), and the end faces 141B and 141C have different shapes. may be Further, the shape of the intervening member may be changed as long as it covers the end surface of the door handle. For example, as indicated by the two-dot chain line in FIG. 19, the intervening members 151 and 152 may have a substantially rectangular shape that is one size larger than the end faces 141B and 141C.
