The slope forming the head-side convex portion 27 is a surface whose height increases in the counterclockwise direction (counterclockwise direction) when the head portion 20 is viewed from above, and is from the thickness direction of the floor panel FP. The shape you see is a quadrilateral. The vertical surface forming the head-side convex portion 27 is a surface whose height decreases linearly from the apex of the slope along the thickness direction of the floor panel FP, and has a shape seen from the circumferential direction of the head-side mounting portion 21. Is a quadrilateral. The two side surfaces forming the head-side convex portion 27 are surfaces that are continuous with the slope and the vertical surface, and the shape of the head-side mounting portion 21 as viewed from the radial direction is a right triangle.

As described above, when the head portion 20 is rotated clockwise with respect to the pedestal portion 10, the slope forming the head side convex portion 27 and the slope forming the pedestal side convex portion 18 are deformed while being in contact with each other. As a result, when the head portion 20 is rotated clockwise with respect to the pedestal portion 10, the slope forming the head side convex portion 27 gets over while contacting the slope forming the pedestal side convex portion 18. Therefore, the head portion 20 with respect to the pedestal portion 10 is allowed to rotate in the clockwise direction.
On the other hand, when the head portion 20 is rotated counterclockwise with respect to the pedestal portion 10, the vertical surface forming the head side convex portion 27 and the vertical surface forming the pedestal side convex portion 18 come into contact with each other. In order for the vertical surface forming the head-side convex portion 27 and the vertical surface forming the pedestal-side convex portion 18 to be deformed while in contact with each other, the slope forming the head-side convex portion 27 and the pedestal-side convex portion 18 are formed. It is necessary to apply a larger force than when the slopes forming the above are deformed while being in contact with each other.

That is, in order for the vertical surface forming the head-side convex portion 27 to get over while contacting the vertical surface forming the pedestal-side convex portion 18, the slope forming the head-side convex portion 27 touches the pedestal-side convex portion 18. It is necessary to apply a larger force than when overcoming while contacting the slope to be formed. Therefore, the rotation of the head portion 20 with respect to the pedestal portion 10 in the counterclockwise direction is restricted.
Therefore, the pedestal side detent portion 17 and the head side detent portion 26 form a loosening prevention mechanism that holds the state in which the male screw portion 23 and the female screw portion 13 are in mesh with each other at an arbitrary position.
The head-side protruding portion 24 is arranged at a position farther from the pedestal frame portion 12 than the flange portion 22, and protrudes from the flange portion 22 in a direction away from the foundation surface B.

The shape of the head-side protrusion 24 is, for example, a shape in which a tool such as a spanner engages.
Further, when the head portion 20 is attached to the upper surface of the head side protruding portion 24 (the surface opposite to the surface facing the flange portion 22) from above with respect to the pedestal portion 10, the head portion 20 is attached by a tool such as a spanner. The rotation notation 28, which is a notation of the direction in which the wrench is rotated, is formed. In the first embodiment, the direction in which the head portion 20 is rotated when the head portion 20 is attached to the pedestal portion 10 from above is the direction in which the head portion 20 is rotated in the clockwise direction with respect to the pedestal portion 10. is there.
