PROBLEM TO BE SOLVED: To prevent contamination of a cover for protecting a body from being conspicuous and hence ensure a good appearance by providing recessed parts each having a longitudinal extending cross section separated at an equal interval in a front surface of a front cover, opposite side surfaces and a back surface of a rear cover, and each surface of an electric packaging cover. SOLUTION: There are provided a synthetic resin front cover 2 composed of an upper surface and a front surface, a synthetic resin rear cover 3 composed of opposite side surfaces and a back surface, and a synthetic resin electric cover 4 for covering an opening for electric packaging provided on the other side surface. These covers 2, 3, 4 are deposited to protect a main body 1. Recessed parts each having a longitudinal extending cross section and separated at an equal interval are provided in the front surface of the front cover 2, opposite side surfaces and a back surface of the rear cover 3, and each surface of the electric packaging cover 4. Hereby, when contamination on each surface is promoted owing to adhering of fur thereto, contamination is prevented from being conspicuous owing to formation of a longitudinal pattern due to the recessed part. |
