Abstract:
A waterproof structure of a connecting portion, comprising:a first member having an elastically-deformable projection at one end; and a second member having a contact surface contacting one of an outer surface and an inner surface of the projection, wherein the projection is pressed on the contact surface of the second member and deformed elastically so as to bend in a direction approximately perpendicular to a direction in which the first member and the second member are assembled when the first member and the second member are coupled to each other, and the contact surface and the projection are brought into contact with each other to form a waterproof region; and wherein the contact surface of the second member is formed such that when the first member and the second member are coupled to each other, a base of the projection is prevented from contacting the contact surface and an end portion thereof contacts the contact surface.
