The lock/unlock button 50 has a first claw portion 51 and a second claw portion 52 as a plurality of claw portions. A first engaging portion 51a is formed, and the second claw portion 52 is formed with a second engaging portion 52a that engages with the lock plate 60 on the back side.
The concave portions 53 of the first claw portion 51 and the second claw portion 52 are engaged with the body portion 62 of the lock plate 60 . Although the case where two claws are used as the plurality of claws is described as an example here, more claws may be provided.
The lock plate 60 is in the unlocked state at the position shown in FIG. 5, and is at the locked position at the position shown in FIG.

The lock mechanism 48 is provided with a spring 55 for biasing the lock plate 60. The spring 55 biases the lock plate 60 to the locked/unlocked position. One end of the spring 55 is attached to a rib 49 projecting from the replacement door 41 , and the other end is fitted to the plate body 61 of the lock plate 60 .

The lock plate 60 is composed of a plate body 61 and a body portion 62 . The plate body 61 is urged by a spring 55 to the locked/unlocked position.

The lateral widths of the first engaging portion 51a of the first claw portion 51 and the second engaging portion 52a of the second claw portion 52 of the locking/unlocking button 50 are configured to have different lengths. This is for attaching the lock plate 60 to the lock/unlock button 50 at the correct position. Therefore, only the first concave portion 64 of the lock plate 60 is engaged with the first engaging portion 51 a of the first claw portion 51 , and the second engaging portion 52 a of the second claw portion 52 is engaged with the lock plate 60 . Only the second recess 65 is configured to engage. This prevents the first engaging portion 51 a of the first claw portion 51 from accidentally engaging with the second recessed portion 65 of the lock plate 60 , and allows the lock plate 60 to be positioned at the correct position of the lock/unlock button 50 . so that it can be worn.

FIG. 9 is a diagram for explaining the length of the engaging portion of the claw portion of the locking/unlocking button of the toilet roll holder according to the embodiment of the present invention.
The length T of the first engaging portion 51a and the second engaging portion 52a of the locking/unlocking button 50 is preferably 0.8 mm or more and 2.5 mm or less. The amount of depression of the first concave portion 64 and the second concave portion 65 of the lock plate 60 must be set according to the length T of the first engaging portion 51a and the second engaging portion 52a.
By setting the lengths of the first engaging portion 51a and the second engaging portion 52a within the above range, the strength of the claw portion itself can be increased, and the strength can be increased about three times that of the conventional art. If the lengths of the first engaging portion 51a and the second engaging portion 52a are too short, the strength becomes weak. Also, if the lengths of the first engaging portion 51a and the second engaging portion 52a are too long, the thin portion of the outer part increases, and the strength of the outer part becomes insufficient.

As shown in FIGS. 5, 6 and 8, the replacement door (housing) 41 is formed with a base portion 45 for attaching the lock/unlock button 50 to the replacement door 41. As shown in FIG. Further, the base portion 45 is formed with rotation restricting portions 46 and 47 that restrict the amount of rotation of the locking/unlocking button 50 . The rotation restricting portions 46 and 47 can restrict the movable range of the locking/unlocking button 50 within a predetermined range, and prevent the locking/unlocking button 50 from turning outside the movable range.

As shown in FIG. 5 , the lid portion 70 is formed with a circular annular portion 71 projecting in conformity with the outer shape of the body portion 62 of the lock plate 60 . The ribs 73 are structured to be fitted with the ribs 49 provided on the replacement door 41 .
A pawl portion restricting portion 72 is formed substantially in the center of the annular portion 71 of the lid portion 70 . It is designed to fit in the space between the first claw portion 51 and the second claw portion 52 .

FIG. 10 is a diagram showing that the pawl restricting portion 72 is accommodated in the space between the first pawl portion 51 and the second pawl portion 52 of the locking/unlocking button 50. As shown in FIG.
The claw portion restricting portion 72 of the lid portion 70 is accommodated in the space between the first claw portion 51 and the second claw portion 52 of the locking/unlocking button 50, so that the locking/unlocking button 50 can be rotated by a jig such as a hexagonal wrench. When the first claw portion 51 and the second claw portion 52 are bent inward, the first engaging portion 51a of the first claw portion 51 and the second engaging portion 51a of the second claw portion 52 are engaged. Since the mating portion 52a is properly engaged with the first recess 64 and the second recess 65 of the lock plate 60, idle rotation of the lock mechanism 48 caused by turning the hexagonal wrench S can be prevented.

The claw portion restricting portion 72 only needs to be able to prevent the first claw portion 51 and the second claw portion 52 of the lock/unlock button 50 from moving from their normal positions, and may be formed in a columnar or cylindrical shape, for example. can be done. In the illustrated example, the case where the claw portion restricting portion 72 is formed in a cylindrical shape has been described as an example.
Although an example in which the claw portion regulating portion 72 is formed on the lid portion 70 has been described, the claw portion regulating portion 72 can also be formed at a location other than the lid portion 70 .

According to this embodiment, the lengths of the first engaging portion 51a of the first claw portion 51 and the second engaging portion 52a of the second claw portion 52 of the locking/unlocking button 50 are set within appropriate ranges, thereby enabling the operation to be performed. A 1.8 times higher torque strength was obtained without affecting the force.
Furthermore, by providing the claw portion restricting portion 72 on the lid portion 70, even when excessive torque is applied, the first claw portion 51 and the second claw portion 52 of the locking/unlocking button 50 can be bent inward from their normal positions. This prevents the locking/unlocking button 50 and the lock plate 60 from being disengaged from each other, and prevents the claw portion of the locking/unlocking button 50 from overriding the engagement portion with the lock plate 60 and only the claw portion turning round and round. can be prevented. Also, the first engaging portion 51a of the first claw portion 51 and the second engaging portion 52a of the second claw portion 52 of the locking/unlocking button 50 are rubbed against the concave portion 64 and the concave portion 65 of the lock plate 60 and scraped off. will be gone.
By adopting this configuration, the strength against torque was increased by 2.1 times. Furthermore, by using the hexagonal wrench S (36% shortened) with a short handle, the load applied to the end of the wrench was five times or more stronger.

Although the present invention has been described above using the embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope of the above embodiments, and various changes or improvements can be made to the above embodiments. It is clear to those skilled in the art that In addition, it is clear from the description of the scope of the claims that forms with such modifications or improvements can also be included in the technical scope of the present invention.
