Although the length is shortened, the insertion shaft member 4 is inserted into the hollow chamber 60 of the hollow shaft member 6, and the double shaft structure is maintained. For this reason, when the base 30 of the toilet seat device 1 is lowered again at the end of cleaning, the insertion shaft member 4 is maintained in the state of being inserted into the hollow shaft member 6. Performs a guiding action, the displacement of the base 30 is suppressed, and the lowering operation of the base 30 can be easily performed. Therefore, the insertion shaft-shaped member 4 can also function as a guide shaft for suppressing the displacement of the base 30.
[0034]
As described above, since the insertion shaft-shaped member 4 projects downward so as to be inserted into the hollow chamber 60 of the hollow shaft-shaped member 6, unlike the above-described prior art, the insertion shaft-shaped member 4 has the toilet seat device. It is possible to suppress a significant amount of upward projection in the accommodation room 30 w of the first base 30. Therefore, the insertion shaft-shaped member 4 does not become an obstacle in the accommodation room 30 w of the base 30, and the mounting parts such as the washing nozzle and the hot water tank related to the function of the toilet seat device 1 are arranged in the accommodation room 30 w of the base 30. In addition, it is possible to provide the toilet seat device 1 in which the mounted components cannot be arranged at the optimum positions, and which is advantageous in securing the degree of freedom of design in the base 30.
[0035]
The pitch P1 (see FIG. 2) of the mounting holes 21 of the toilet 2 is generally specified by a standard (JIS standard). Therefore, if the pitch P3 of the plurality (two) of the hollow shaft members 6 and the pitch P2 of the plurality (two) of the insertion shaft members 4 are matched with the pitch P1 of the mounting holes 21 of the toilet 2, the pitch P3 can be adjusted. Even if the type of the toilet seat device 1 is different depending on the manufacturer, if the first attachment 5 is set so that the first attachment 5 can be attached to the base 30 of the toilet seat device 1, it is provided by each manufacturer.

On the other hand, when the insertion shaft-shaped member 4 is turned in the direction of the arrow R2 and rises from the accommodating portion 50 of the first attachment 5, and is substantially perpendicular to the first attachment 5, FIG. As shown, the tip of the fixing pin 51 presses the inclined second engagement surface 45 of the insertion shaft-shaped member 4, thereby maintaining the insertion shaft-shaped member 4 in an upright state.
[0040]
According to the present embodiment, the fixing pin 51 serves as an insertion shaft-like member posture maintaining means for maintaining the posture of the insertion shaft-like member 4 in the folded state and the upright state with respect to the housing portion 50 of the first attachment 5. Can work.
When rotating the insertion shaft-shaped member 4 in the directions of the arrows R1 and R2, the fixing pin 51 moves in the retreating direction (the direction of the arrow S4) while resisting the urging force of the second urging member 54, so that the rotation is hindered. Does not.
[0041]
Since the first engagement surface 44 and the second engagement surface 45 are formed on the insertion shaft-shaped member 4 as described above, the first engagement surface 44 and the second engagement surface 45 are the first engagement surface. The taper of the first engagement surface 44 and the second engagement surface 45 becomes gentler than the virtual arc M1 when the 44 and the second engagement surface 45 are not formed (see FIGS. 13 and 14). Therefore, when the insertion shaft-shaped member 4 is rotated in the folding direction (the direction of the arrow R1) and the upright direction (the direction of the arrow R2), the fixing pin 51 is easily formed by the first engagement surface 44 and the second engagement surface 45. It can be displaced in the retracting direction (the direction of arrow S4).
