Since the space inside the portion 12 is hidden, it is possible to prevent foreign matter from entering the main body portion 12 of the fixing plate 10 in a state where the movable member 3 is located at the upper end position. Further, from this point, the shielding portion 81 of the cover 80 can prevent the holding member 40 arranged in the main body portion 12 of the fixed plate 10 from being exposed while the movable member 3 is located at the upper end position. For example, it is possible to prevent foreign matter from being caught in the holding member 40. Further, for example, it is possible to prevent a human finger or the like from easily entering the main body 12 of the fixed plate 10 with the movable member 3 located at the upper end position.

As described above, since the sandwiched member 70 includes the rollers 71 that are sandwiched by the pair of sandwiching bodies 41 of the sandwiching member 40 when the movable member 3 moves up and down, the operation when the movable member 3 is moved up and down is performed. It is possible to realize a structure that can be smoothly performed with a simple structure.

As described above, since the stopper 90 that temporarily holds the state in which the movable member 3 is arranged at the lower end position or the upper end position is provided, the movable member 3 unintentionally moves to the lower end position or the upper end position. It is possible to prevent the movable part of the object to be attached from being placed in an unintended elevating position.

Further, as described above, since the fixing plate 10 includes the locking recess 13 and the stopper 90 includes the protruding piece 92 locked in the locking recess 13 of the fixing plate 10, the movable member 3 is in the lower end position or the upper end position. It is possible to realize a configuration that can temporarily hold the state of being placed in a simple configuration.

As described above, the roller 71 of the sandwiched member 70 is provided with the holding groove 73, and the roller 71 of the sandwiched member 70 is sandwiched in a state where the sandwiching body 41 of the sandwiching member 40 is arranged in the holding groove 73. When the movable member 3 is moved upward or downward to position the movable member 3 from the lower end position to the upper end position or from the upper end position to the lower end position, the holding member 40 can surely hold the state in which the roller 71 is held.

In the elevating device 1, by appropriately changing the specifications such as the material and shape of the holding body 41 of the holding member 40, the holding body 41 of the holding member 40 is held according to the specifications of the Western-style toilet bowl 100 (attachment object). The force can be adjusted.
For example, when it is desired to increase the holding force of the holding body 41 of the holding member 40 and enhance the damper effect when the movable member 3 moves up and down, the holding body 41 of the holding member 40 is made of a harder material. Further, the holding body 41 of the holding member 40 may be made of a larger diameter one. Further, for example, when it is desired to increase the holding force of the holding body 41 of the holding member 40 as the movable member 3 moves downward from the upper end position, the distance between the holding bodies 41 of the holding member 40 is increased. It is configured so that the lower part is narrower than the lower part. Further, the holding body 41 of the holding member 40 can be formed in a substantially V shape, and the holding body 41 of the holding member 40 can be formed in a crank shape. Further, when it is desired to strengthen the damper effect by the holding body 41 of the holding member 40, a configuration including three or more holding members 40 is provided, and when it is desired to weaken the damper effect by the holding body 41 of the holding member 40. , It is also possible to have a configuration including one holding member 40.

As shown in FIG. 9, the pin arrangement hole 63 of the movable plate 60 can be formed long in the vertical direction.
In the elevating device 1 configured in this way, even if the movable plate 60 moves upward when the movable member 3 is moved upward from the lower end position and the mounting body 102 of the Western-style toilet bowl 100 is pulled up by the operator. The pinched member 70 and the slider 50 do not move upward until the lower end of the pin arrangement hole 63 of the movable plate 60 comes into contact with the roller 71 of the pinched member 70. Further, when the movable member 3 is moved downward from the upper end position, when the worker pushes down the mounting body 102 of the Western-style toilet bowl 100, even if the movable plate 60 moves downward, the pin arrangement hole of the movable plate 60 The held member 70 and the slider 50 do not move downward until the upper end of the 63 abuts on the roller 71 of the held member 70.
