The frame body 1 is provided with a cavity 21 that opens on the outer peripheral side facing the mounting portion J on the floor F side, and the inner peripheral side of the cavity 21 is an inclined surface facing the opposite opening side (downward). The rear surface 22a and the screw insertion portion 22 provided with the screw insertion hole 22b are integrally and movably formed so as to be closed. The front surface 31 is provided with an inclined surface facing the opening side (upward) that abuts on 22a, and is composed of a mounting portion contact member 3 that abuts the rear surface 32 on the mounting portion J on the floor F side. ing.
Here, the left-right direction of the frame body 2 is referred to as an X-axis, the Y-axis is referred to as a vertical direction, and the Z-axis is referred to as a front-rear direction (the inner peripheral side of the frame body 2 is the front direction, and the outer peripheral side is the rear direction).

In this case, the screw insertion portion 22 that closes the inner peripheral side of the cavity portion 21 connects the side portion of the screw insertion portion 22 to the frame body 2 via the support portion 23, specifically, the screw insertion portion. The support portions 23 connected to the side portions of the portions 22 are curved in the vertical direction, and further extended in the horizontal direction to be connected to the frame body 2, so that the support portions 23 can be moved in the vertical direction and the front-rear direction ( It hardly moves in the left-right direction).

The cavity 21 corresponds to a guide piece 24 and a guide groove 25 for guiding the mounting portion contact member 3 mounted in the cavity 21, and the mounting portion contact member 3 corresponds to the guide piece 24 and the guide groove 25. A guided groove 33 and a guided piece 34 are formed at the positions, respectively, so that the mounting portion contact member 3 can move in the front-rear direction in the cavity 21 (almost no movement in the left-right direction and the up-down direction). In addition, by restricting the moving range of the guided piece 34 by the guide groove 25, the mounting portion contact member 3 once mounted is prevented from coming out of the hollow portion 21.
As a result, it is not necessary to individually attach the parts at the work site, and the parts do not come off, so that workability and handleability at the time of construction can be improved.
