It is made to protrude downward in the direction (first step).
At this time, the temporary fixing engaging claw 116b1 of the first leg portion 116b of the temporary fixing holder 116 attached to the metal base 117 is hooked on the peripheral edge of the roof opening 20a, and the first device 11 is temporarily fixed to the roof 20. Will be done.

The first protrusion 117b and the second protrusion 117c are inserted into the second opening 121a1 in the chassis 121 so that the protrusion 1171 of the metal base 117 passes through the first notch 121a2 in the chassis 121 of the second device 12. State before rotation).

The second device 12 is rotated clockwise when viewed from below in the z direction (second step).
At this time, the wall 1222 in the chassis 121 of the second device 12 is rotationally moved along the protrusion 1171 in the first protrusion 117b of the metal base 117, and the first device 11 is moved downward in the z direction with the roof 20 in between. It is moved, and the second device 12 is moved upward in the z direction.

As a result, there is almost no gap between the resin base 118 and the roof 20.
When the detent 121a3 in the chassis 121 of the second device 12 comes into contact with the protrusion 1171, the rotation of the second device 12 is completed (post-rotation state).
Further, the second terminal 122 comes into contact with the first terminal 113, and the first substrate 112 in the first apparatus 11 and the second substrate 123 in the second apparatus 12 are brought into a conductive state.

The screwing member 13 is screwed into the inner wall of the second protruding portion 117c through the bolt hole 126a of the washer 126 (third step).
At this time, the washer 126 is disengaged from the temporary fixing wall 125b of the cover 125 and is moved upward in the z direction together with the screwing member 13, and the upper end portion of the second leg portion 126c moves the locking claw 1211 of the chassis 121 upward in the z direction. The locking claw 1211 and the lower surface of the roof 20 are brought into contact with each other.

As a result, the metal base 117, the screwing member 13, the washer 126, the chassis 121, and the roof 20 are electrically connected to each other, and the metal base 117 is grounded.

In the present embodiment, after the gap between the first device 11 and the roof 20 is made almost zero by using a retracting mechanism such as a wall 1222, the roof of the locking claw 1211 using the second leg 126c of the washer 126 is used. Since the roof 20 is pushed into the roof 20, it is possible to reduce the deformation of the roof 20 as compared with the form in which the pull-in mechanism is not used.

In the present embodiment, a retracting mechanism such as a wall 1222 is used, and an axis parallel to the z direction in which the first device 11 and the second device 12 are arranged (for example, the central axis of the inner wall of the second protruding portion 117c). ), The metal base 117 and the like can be moved in the direction closer to the roof 20 by rotating the second device 12. However, the second device 12 is linearly moved by using the retracting mechanism. By doing so, the metal base 117 or the like may be moved in a direction approaching the roof 20.

Further, in the present embodiment, the embodiment in which the bolt (male screw) as the screwing member 13 is screwed to the inner wall of the second protruding portion 117c of the metal base 117 via the washer 126 has been described. A male screw may be provided at the tip of 117c, and a nut (female screw) as a screwing member 13 may be screwed to the tip of the second protruding portion 117c via a washer 126.

Further, in the present embodiment, the first terminal 113 and the second terminal 122 do not come into contact with each other in the pre-rotation state, and the first terminal 113 and the second terminal 122 come into contact with each other in the post-rotation state. In the pre-rotation state, the first terminal 113 and the second terminal 122 are in weak contact with each other, and in the post-rotation state, the first terminal 113 and the second terminal 122 are in contact with each other. The first terminal 113 and the second terminal 122 may be configured so that the two terminals are in strong contact with each other.
In this case, the degree of contact between the first terminal 113 and the second terminal 122 in the post-rotation state is stronger than the degree of contact between the first terminal 113 and the second terminal 122 in the pre-rotation state. The positional relationship between the members of the 1st device 11 and the 2nd device 12 is determined.
