A fastening member is pivotally supported on the threaded movable member, and this fastening member is urged by a spring in a direction to protrude from the side plate. A clamping part is provided that clamps the installation base material between the fastening member that is protruded by force, and the movable member is further retreated in a direction away from the clamping part by rotation of the screw shaft. In some cases, a pressing part is provided that contacts the fastening member and rotates the fastening member inward of the side plate against the biasing force of the spring by relative movement with the moving member that moves backward. It is.

In this mounting device, when the device body is attached to the installation base material, when the screw shaft is rotated and the movable member is moved in the direction of the installation base material, the fastening member that is protruded from the movable member by the spring is connected to the screw shaft. The installation base material is held between the opposing holding parts, and the device main body is fixed. When the device main body is removed from the installation base material, the screw shaft is rotated to move the movable member back away from the installation base material. At this time, due to the backward movement of the movable member, the holding member supported by the movable member is pressed by the pressing portion, rotates inward of the side plate, and moves to a position where it does not hit the installation base material. Therefore, the device main body can be removed from the installation base material without the fastening member hitting the installation base material.
