Patent attributes
A casing 1, a lid component 11 for covering a terminal 13 disposed in an opening of the casing 1, and a water sealing component 12 disposed around the terminal 13, are provided. The lid component 11 is structured such that a support portion 11h of a fixing portion 11g is rotatably fixed to the casing 1, and a slidable portion 11b slides relative to a lid portion 11a. Thus, a projection 11c is engaged with a recess 14, and a pair of engagement portions 11f engages with a pair of fixed projections 16. Thus, the lid component 11 engages with the casing 1 in three directions, and is held by being pressed against the water sealing component 12. With this structure, an electronic device having a lid component which can be assuredly locked is obtained.
