I'm here. Here, in a state where the armrest receiver 50 with the spacer 60 attached thereto is inserted into the insertion hole 11, the spacer 60 is entirely sunk into the insertion hole 11. However, part of the spacer 60 may sink into the insertion hole 11. At least a portion of the spacer 60 sinks into the insertion hole 11, so that the armrest receiver 50 is stably supported by the seat portion 10. Furthermore, this allows the armrest receiver 50 to be sandwiched between the pair of spacers 60A and 60B without relying on the fixing pin 70.

By making the vertical position of the armrest holder 50 relative to the seat part 10 changeable, the height adjustment range of the armrest 40 can be widened without widening the adjustment range of the armrest holder 50. This makes it possible to adjust the height of the armrest 40 particularly to users with large physiques, which are increasing in recent years. The height adjustment range of the armrest 40 is preferably 100 mm or more. More preferably, the lower limit of the height of the armrest 40 from the upper surface of the seat portion 10 is 0 mm, and the upper limit is 100 mm or more. The height from the lower surface of the leg 21 (the installation surface of the portable toilet 100) to the upper surface of the armrest 40 is preferably 420 mm or more. It is more preferable that the height from the lower surface of the leg 21 to the upper surface of the armrest 40 be 450 mm or more.

[Operations and effects of embodiment]
Below, the effects that can be achieved by the portable toilet 100 according to this embodiment will be explained.
