  First, a state before the apparatus body 130 starts to rise, that is, a state before the toilet seat apparatus 30 rises will be described.

  As shown in FIG. 7B, the lever 150 as the release means 151 is in a state before the pressing operation, and is located to the right compared to the state after the pressing operation. As a result, each configuration of the lifting device 100 is in the following movement or state.

  As shown in FIG. 7A, at least a part of the cylinder 134 is accommodated in the box 140. Further, as shown in FIG. 7B, the locking means 161 is elastic by holding the elastic body 132 in a compressed state by the first engaging portion 160 engaging with the first engaged portion 118. The apparatus main body 130 is locked so that the restoring force of the body 132 does not work and the apparatus main body 130 does not start to rise. In addition, the prevention means 163 is configured so that the second engagement portion 162 is opposed to the second engaged portion 122 in the vertical direction, but is not engaged with the second engagement portion 122, but when the toilet seat device 30 is to be removed. It is in a state where the removal can be prevented.

  As a result of the above, as shown in FIG. 7A, the box 140 of the apparatus main body 130 remains at a predetermined initial position from the installation base 110.

  Next, the state in which the apparatus main body 130 is rising will be described.

  As shown in FIG. 8B, the lever 150 serving as the release means 151 is positioned from the right side to the left side as compared to the state before the pressing operation when the operating unit 102 is pressed. As a result, each configuration of the apparatus main body 130 has the following movement or state.

  The release unit 151 releases the lock of the apparatus main body 130 by a push operation. That is, the release means 151 releases the engagement with the first engaged portion 118 by moving the first engagement portion 160 as the lock means 161 inward. At the same time, the release means 151 is moved in response to the pressing operation of the link 168, and the respective engaging portions of the second engaging portion 162 are simultaneously moved toward the central portion. The joining portion 162 releases the possibility of engagement with the second engaged portion 122, and also releases the removal prevention. As a result of the above, as shown in FIG. 8A, the restoring force of the elastic body 132 works and the ceiling 140D is pushed up by the restoring force, so that the box 140 is set at an initial position predetermined with respect to the installation table 110. Ascends away from. At this time, although the cylindrical body 134 is held by the box body 140 but is not fixed, the cylindrical body 134 also rises relative to the cylindrical body 134. Therefore, the cylindrical body 134 is in a state in which a large number of portions protrude from the hole 142 to the outside as compared to before the ascent.

  Next, although not shown, when the pushing operation is finished, the coil spring 159 applies a pulling force to the first engaging portion 160 so as to return the operation portion 102 to the original position before the pushing operation, The lever 150 as the release means 151 is located on the left side to the right side as compared with the state at the time of the pressing operation when the operating unit 102 is pressed. As a result, the releasing means 151 makes the second engaging portion 162 and the second engaged portion 122 as the preventing means 163 face each other so that they can be engaged with each other, thereby preventing the removal again.

  Next, the state after the apparatus main body 130 is raised will be described.

As shown in FIG. 9A, even after the pushing operation is finished, the box 140 of the apparatus main body 130 rises due to the restoring force of the elastic body 132, and the second engaging portion 162 is moved at a predetermined position. It stops by engaging with the second engaged portion 122, and the apparatus main body 130 is in a state after ascending. As a result, the preventing means 163 constructed by the second engaging portion 162 and the second engaged portion 122 prevents the toilet seat device 30 from being removed again. In addition, the cylindrical body 134 is in a state in which many portions protrude from the hole portion 142 to the outside as compared to when the cylindrical body 134 is rising.
As shown in FIG. 9B, the lever 150 as the release means 151 is in a state before the pressing operation, and is located to the right compared to the state after the pressing operation. Further, the locking means 161 does not lock the apparatus main body 130 because the first engaging portion 160 is not engaged with the first engaged portion 118.

  Next, a state when the apparatus main body 130 is removed will be described.

  As shown in FIG. 10B, the lever 150 as the release means 151 has a pressing operation of the operation unit 102 and is located on the right side to the left side compared to the state before the pressing operation. As a result, each configuration of the apparatus main body 130 has the following movement or state.

  The release means 151 maintains the state where the lock of the apparatus main body 130 has already been released, although the first engagement portion 160 is moved inward. At the same time, the release means 151 is moved in response to the pressing operation of the link 168, and the respective engaging portions of the second engaging portion 162 are simultaneously moved toward the central portion. The mating portion 162 releases the engagement with the second engaged portion 122 and also releases the removal prevention.

  Finally, a state after the apparatus main body 130 is removed will be described.

  When the user lifts the toilet seat device 30 while removing the toilet seat device 30 while maintaining the pushing operation, the state of the top view shown in FIG. 11B remains the same as the state shown in FIG. The state of the front sectional view shown in FIG. 10 changes from the state shown in FIG. That is, as the toilet seat apparatus 30 is lifted, the apparatus main body 130 is lifted together beyond a predetermined position. Accordingly, the main body 130 of the toilet seat device 30 is also removed together with the cylindrical body 134 holding the elastic body 132.
