It is united in the state. Further, the roller 43 rolls, so that the seat body 4 can smoothly rotate with respect to the first base 3.

  FIG. 7 is a side sectional view of the positioning mechanism 5. A rotation positioning mechanism 5 as a rotation angle positioning means is provided below the main body 4a. The seat body 4 is configured in a line-symmetric shape, and a positioning mechanism 5 is provided at the front end on the center line. A support portion 52 projects downward on the lower surface of the main body portion 4a, and a lever 51 is supported on the support portion 52 via a shaft 511 so as to be swingable. Further, a positioning pin 53 is held on the support portion 52 so as to be able to reciprocate toward the center of the annular smooth surface 33. The distal end portion of the positioning pin 53 is a spring receiving portion 551 having an enlarged diameter, and one end of a compression spring 54 as an urging means externally mounted on the positioning pin 53 contacts the spring receiving portion 551. The other end of the compression spring 54 is in contact with a spring receiving member 521 inserted between the working surface 512 or 513 of the lever 51.

  A locking portion 55 is provided on the tip surface of the positioning pin 53 by a convex portion protruding in a spherical shape. On the other hand, as shown in FIG. 1, a concave engaging portion 312 is formed on the outer peripheral surface 311 of the first base 3. A plurality of engaging portions 312 are provided at equal intervals. The engaging portion 312 engages with the engaging portion 55 of the positioning pin 53.

  In the vicinity of the shaft 511 of the lever 51, a release action surface 512 and a lock action surface 513 that are orthogonal to each other are provided. The lock action surface 513 is configured to have a long distance from the shaft 511 to the action surface, and the release action surface 512 is configured to be short. The state indicated by the imaginary line in FIGS. 6 and 7 shows a state in which the lever 51 is set downward and the release action surface 512 is in contact with the spring receiving member 521. In this state, the compression spring 54 is in an extended state, and the force for urging the positioning pin 53 toward the outer peripheral surface 311 of the first base 3 is small. In this state, when the seat body 4 is rotated with respect to the first base 3, the distal end of the positioning pin 53 easily disengages from the engaging portion 312 and engages with the next adjacent engaging portion 312. In this way, the seat body 4 receives a rotational resistance each time the positioning pin 53 engages with the plurality of engaging portions 312, and the seat body 4 does not rotate due to inertia. That is, the seat body 4 is temporarily fixed by engaging the tip of the positioning pin 53 with any of the engaging portions 312. By adopting such a configuration, when the rotational position of the seat body 4 is determined and the clothes are taken off for excretion, the seat body 4 may move accidentally due to the clothes being touched by the clothes. Such inconveniences are suppressed.

Further, as shown by the solid line in FIG. 7, when the lever 51 is rotated to a horizontal posture, the lock action surface 513 pushes the spring receiving member 521 toward the positioning pin 53. As a result, the compression spring 54 is further compressed and strongly presses the positioning pin 53 against the engaging portion 312.
Thereby, the seat body 4 cannot rotate with respect to the first base body 3, and the seat body 4 is fixed. That is, since the posture of the seat body 4 is fixed while sitting on the toilet seat, the user can use it in a stable posture.

  A seat 4b is placed and fixed on the main body 4a. Since the seat portion 4b is a separate member from the main body portion 4a, for example, the seat portion 4b is made of a material that can absorb an impact such as an elastic member and is made of a material different from that of the main body portion 4a so as to improve the sitting comfort. Can be configured. In addition, since the skin is in direct contact with the skin, it is possible to construct and attach an antibacterial coating or the like or a structure with a built-in heating element.

  The roller 43 may be supported on the first base 3 side and may be in rolling contact with the lower surface of the seat body 4. Furthermore, the rail bodies 23a to 23d may be provided on the first base 3 side, and the moving bodies 34a to 34d may be provided on the second base 2 side.
