  The relative movement of the center plate member 40 with respect to the second frame member 20 is such that the locking piece 42 contacts the front wall 22 in the X2 direction until the locking piece 42 abuts against the rear wall 23 in the X1 direction. Until it touches.

  As described above, the movement of the center plate member 40 is restricted by the stopper piece 17, so that the first moving space A does not need to have a large area. On the other hand, in order to absorb the fluctuation of the housing, it is necessary to widen the second movement space B to secure the movement width of the center plate member 40. In the present embodiment, the second frame member 20 is formed wider in the X direction than the first frame member 11, whereby the width of the second movement space B is larger than the width of the first movement space A. It is formed.

  In addition, when one of the housings 55 and the other housing 56 is relatively displaced in the Y direction (the direction parallel to the wall of the housing), the center plate member 40 slides as shown in FIG. Absorb.

  As described above, the first frame member 11 is provided with the stopper piece 17 which can be engaged with the center plate member 40, and the stopper piece 17 is the relative of the center plate member 40 to the first frame member 11.

Even in this case, the end of the center plate member 40 can be received by the stopper piece 17 and the wall 55b of the floor 55a. That is, since the center plate member 40 can be received in a wide range by providing the stopper piece 17, the load is not concentrated on a part of the center plate member 40, and the breakage hardly occurs.

  Further, the first frame member 11 is provided with a rising piece 13 engageable with the center plate member 40, and the rising piece 13 moves the center plate member 40 relative to the first frame member 11. It is for restricting, and restricts relative movement of the center plate member 40 in the direction of the other housing 56 as viewed from the one housing 55. That is, the relative movement of the center plate member 40 with respect to one of the housings 55 is restricted by the rising pieces 13. According to such a configuration, it is possible to prevent the center plate member 40 from being detached from the first frame member 11.

  Further, one end portion of the center plate member 40 is movable in a first movement space A formed by the first frame member 11 and the first cover member 18, and the one end portion of the center plate member 40 is The other end is movable in a second moving space B formed by the second frame member 20 and the second cover member 26, and the width of the second moving space B is the first moving space.

Further, as shown in FIG. 9, the finish sheet 51 may be attached to the upper surface of the center plate member 40.

  Since the thickness of the center plate member 40 is increased when the finished sheet 51 is attached to the upper surface of the center plate member 40, the lower portion 36d of the third cover member 36 is on the upper surface of the center plate member 40 in the above embodiment. It may interfere and not be delivered. Therefore, as shown in FIG. 9B, the projecting piece 34 is made to project from the upper part of the upper wall 33 of the third frame member 30, and the surface of the projecting piece 34 (the surface facing the third cover member 36) A concave portion 34a for receiving a screw is provided on the side wall, and the cover fixing screw 48 can be screwed by using the concave portion 34a. In the third cover member 36, a countersunk hole for inserting the cover fixing screw 48 is formed by a press, so that the peripheral portion of the countersink slightly protrudes on the back side. In order to release the peripheral edge of the countersink projecting to the back side, the above-mentioned recess 34a is provided. The upper and lower width of the recess 34a is set to be larger than the width of the countersink, so that the countersink can be mounted offset with respect to the recess 34a. As described above, since the third cover member 36 and the cover fixing screw 48 can be attached by being shifted upward, the third cover member 36 is positioned to a position where the lower portion 36 d of the third cover member 36 does not interfere with the upper surface of the center plate member 40. The mounting position of can be raised.

  Similarly, when the finish sheet 51 is attached to the upper surface of the center plate member 40, the thickness of the center plate member 40 is increased, so the lower surface of the second cover member 26 is on the upper surface of the center plate member 40 in the above embodiment. It may interfere and not be delivered. Therefore, as shown in FIG. 9C, the receiving piece 23b is projected substantially horizontally inside the rear wall portion 23 of the second frame member 20, and the cover fixing screw 47 is utilized by using the receiving piece 23b. I am able to screw it on. The spacer 52 can be disposed between the receiving piece 23 b and the cover 26 a of the second cover 26. By arranging the spacer member 52, the height of the second cover member 26 can be increased, so that the second cover member 26 is attached at a high position to a position where the second cover member 26 does not interfere with the upper surface of the center plate member 40. can do.
