Abstract

PURPOSE:To obtain an improved waterproof mechanism, by a method wherein a packing, which has a stretching inner edge part and an extending end part being nipped betwen a back cover and a case, is built in. CONSTITUTION:A packing 7 is formed such that its stretching inner edge part supports a staged part 5a of a movement body 5 and acts as a fastening member for the movement at a nonwaterproofing side. A packing end part 7b, which extends at an angle with the inner edge part 7a, is nipped between an outer surface of a staged part 2a on an upper side of a back cover 2 and an inner surface part 1c of a case 1 to perform a waterproof function at a waterproof side. The back 2 and the case 1 are adhered firmly until a packing 7 is compressed in the direction of the thickness between a bezel back side staged part 1b of the case 1 and the back 2, and a strong compression force is applied to the rim part 7b of the packing 7 through the working of the staged part 2a on the upper side of the back 2 and the inner side surface part 1c. This causes the packing 7 to form a wide sealing surface area and to display a more tight waterproofing function.
