The cover includes a pair of side wall portions which is disposed so as to face each other with the fusible portion interposed therebetween, and a connection portion which connects the pair of side wall portions. The housing includes a guide wall which is configured to guide the cover toward the fusible portion when the cover is attached to the housing. The guide wall is inclined to a direction intersecting a separation direction in which the cover is separated from the housing.

An electronic component protecting cover includes a fixed cover portion, a hinge portion, and a rotatable cover portion. One of the fixed cover portion and the rotatable cover portion has engaging portions at two locations, and the other of the fixed cover portion and the rotatable cover portion has catching portions at two locations, the engaging portions and the catching portions being configured to be engaged with each other. Each of the engaging portions has a pair of locking tabs, and each of the catching portions has a pair of locking frames. Because each of the engaging portions and each of the catching portions has double-locking structure, sufficient locking force can be provided.
