However, the above-mentioned slide type lid is generally provided with a waterproof structure. It is impossible to provide complete waterproofing. On the other hand, even in a configuration in which the rechargeable battery casing is made independent, it is necessary to provide a waterproof structure at the joint between the two rechargeable batteries because the rechargeable battery and the electronic circuit on the main body casing side are connected. An extremely common waterproofing method is adopted in which a flat packing is interposed on the end face of the housing and the packing is clamped by each end face by tightening both housings with screws passing in the direction perpendicular to the joining end face. I have.

うな事態が生じる。The above-mentioned slide type lid cannot adopt a waterproof structure because the lid guided by the slide mechanism when the packing is interposed is slid with respect to the surface of the opening. Is not possible. On the other hand, if the lid is configured to be pivotally attached to the body housing side, the locking mechanism between the rotation lid and the body housing side in a direction perpendicular to the surface of the opening is provided. It is necessary to provide the cover, and the lock in the opening direction of the lid is weakened, so that the squeezing pressure of the packing cannot be sufficiently ensured, and a situation occurs in which the lid is unintentionally opened.

能性がある。[0006] Next, when joining the end faces of the casings, in the general method of clamping the interposed packing with screws as described above, a flange portion is formed on the outer peripheral side of each casing. It is necessary to adopt a structure that tightens with screws or a structure that tightens the other case with a long screw that penetrates the inside of one case.In the former case, the size of the case increases, In the latter case, there is a disadvantage that the internal storage space is limited. To solve this problem, a waterproof structure for a housing as shown in FIG. 15 (Japanese Utility Model Laid-Open No. 6-60027) has been proposed. In this structure, a U-shaped groove 103 is formed on the entire circumference of the open end face 102 of one case 101, and an enclosure wall 104 is provided upright along the entire inner periphery of the U-shaped groove 103. An engaging wall 106 having an engaging hole 105 is provided, and a waterproof member 107 having a circular cross section is fitted into the U-shaped groove 103. A projection 109 is formed on the inner surface of the other case 108, and this projection is formed. The waterproof member 107 is pressed by the open end face 110 of the other case 108 by engaging 109 with the engagement hole 105 of the one case 101. According to this structure, as shown in FIG. 15 (B), when the case 108 is joined to the case 101, the case 109 comes into contact with the engagement wall 106 because the front side of the projection 109 is inclined. 108 is bent outward, and the projection 109 is

Are pressed against each other. However, although the front side of the projection 109 is an inclined surface, the rear side is a surface perpendicular to the inner wall of the case 108, so it is difficult to release this once it is joined, and it can be freely opened and closed. It is not a simple structure. If the rear surface of the projection 109 is also inclined, it can be freely opened and closed. However, there is a possibility that a sufficient pressing force against the waterproof member 107 cannot be obtained, and the projection may come off at an unintended time.
