The second engaging portion 22c is provided at a portion different from the corner portions 2e, 2f, 2g, and 2h of the second side wall 22b and divided into a plurality of portions of the long side portions 2a and 2b and the short side portions 2c and 2d. It has been. Furthermore, the central portion of the ceiling wall portion 22a located along the second side wall 22b corresponding to the one short side portion 2c of the upper case 22 has a wall thickness that is greater than that of both sides in the direction along the short side portion 2c. A thin recess 22d is formed. Since the recess 22d is thin, it has a step 22e in the direction along the short side 2c.

  As shown in FIG. 5 and FIG. 6A, the housing 2 of the present embodiment is configured such that the ceiling wall portion 22a faces the bottom wall portion 21a, and the second side wall 22b surrounds the first side wall 21b. The upper case 22 is put on the lower case 21. Then, as shown in FIG. 5B, snap engagement is performed by the first engagement portion 21c and the second engagement portion 22c provided at a plurality of locations of the housing 2.

  At this time, in the engaging portion between the first engaging portion 21c and the second engaging portion 22c, the first engaging portion 21c is pushed by the second engaging portion 22c from the outer peripheral side and elastically deformed inward. doing. On the other hand, the second engaging portion 22c is stressed by the reaction. Since the engaging portions as shown in FIG. 5B are provided separately at a plurality of locations of the housing 2, the independence of the engagement between the first engaging portion 21c and the second engaging portion 22c is improved. Therefore, the followability of the engaging portion is improved, and snap engagement can be ensured. As a result, the housing 2 is not disengaged from the snap by normal handling.

  FIG. 6B is a cross-sectional view cut at a position where the second side wall 22b and the first side wall 21b are in contact with each other. As shown in FIG. 6 (b), the housing 2 in the present embodiment has a gap between the inner surface of the second side wall 22 b of the upper case 22 positioned at the corners 2 e, 2 f, 2 g, 2 h and the lower case 21. Has GS. In addition, a gap GS is formed between the inner surface of the second side wall 22 b and the lower case 21 at the center along the short side 2 c of the upper case 22. The position of the gap GS corresponds to a recess 22d and a step 22e formed in the ceiling wall 22a shown in FIG. The gaps GS at the plurality of locations are illustrated with the same reference numerals, but may have different sizes.

  Due to its handling, the portable remote control device 1 may be accidentally dropped onto the ground or floor from the height of the operator's height. The housing 2 is required to be hard to break due to the impact caused by the dropping. When the portable remote control device 1 falls, there is a high possibility that one of the corners 2e, 2f, 2g, and 2h of the housing 2 will collide first. In addition to the corner portions 2e, 2f, 2g, and 2h, there is a high possibility that the central portion of the short side portion 2c will collide first.

  In the portable remote control device 1 of the present embodiment, the following countermeasures are taken against the impact that one of the corners 2e, 2f, 2g, and 2h of the housing 2 collides first. At the corners 2e, 2f, 2g, and 2h of the housing 2, a gap GS is formed between the inner surface of the second side wall 22b of the upper case 22 and the lower case 21 positioned inside thereof, so When an impact is applied, the second side wall 22b can be elastically deformed inward. By forming the gap GS, when the impact is applied, the second side wall 22b is elastically deformed and the instantaneous maximum impact is alleviated. Therefore, even if the impact is alleviated and the stress is concentrated on the corners 2e, 2f, 2g, and 2h, the upper case 22 can be hardly damaged without increasing the thickness.

  In the portable remote control device 1 of the present embodiment, the following countermeasures are taken against the impact that the central portion of the short side portion 2c collides first. Since the thin concave portion 22d is provided in the central portion of the ceiling wall portion 22a in the portion corresponding to the short side portion 2c, the upper case 22 in the vicinity of the concave portion 22d is easily bent. Therefore, when falling from the short side 2c side, the upper case 22 can be made more difficult to break without increasing the thickness. Furthermore, if the recess 22d is formed with a step 22e on the ceiling wall portion 22a, stress due to impact tends to concentrate on the portion of the step 22e having a different thickness, but this corresponds to the step 22e. The second side wall 22 b in the portion has a gap GS between the lower case 21. Due to the gap GS corresponding to the step 22e and the recess 22d, the second side wall 22b of this portion can be elastically deformed. For this reason, even if the recessed part 22d which has the level | step difference 22e in the ceiling wall part 22a is formed, it can suppress that the upper case 22 becomes easy to break without increasing thickness.

  Hereinafter, the effect by having set it as this embodiment is demonstrated.

  If the concave portion 22d is formed with a step 22e on the ceiling wall portion 22a, stress due to impact tends to concentrate on the portion of the step 22e having a different thickness, but in the portion corresponding to the step 22e. The second side wall 22b has a gap GS between the lower case 21 and the second side wall 22b. The second side wall 22b can be elastically deformed by the gap GS corresponding to the step 22e and the recess 22d. For this reason, even if the recessed part 22d which has the level | step difference 22e in the ceiling wall part 22a is formed, it can suppress that the upper case 22 becomes easy to break.

  In the portable remote control device 1 of the present embodiment, the second side wall 22b in the portion corresponding to the pair of long sides 2a, 2b and the pair of short sides 2c, 2d is engaged with the first engagement portion 21c.
