PURPOSE:To hold both a cover and a base at the same electric potential and to improve operational efficiency of assembly by attaching an end of a connection of the cover to an end of a connection of the base through a deformed O ring and a plate O ring. CONSTITUTION:A cover 2 whereto an LCD 1, etc., is incorporated is rotatively attached to a base 3 of a molding material which contains a unit device. A connection end 13 of the cover 2 is provided with a through hole 9 at a center thereof and a plurality of protrusions 4 for fixing of a deformed O ring 12 which is provided to a periphery thereof. A connection end 5 of the base 3 is provided with a hole 16 for inserting of a rotating axle 14 which is provided to a center thereof and a recess 6 for inserting of a plurality of hook sections 7 of a plate O ring 8 rotatively. The deformed O ring 12 is provided with a bent section 11 provided to a part of a periphery thereof, a through hole 9 for inserting of a rotating axle 14 provided to a center thereof, and a fixing hole 10 which is provided for inserting of a protrusion 4 of a connection of the cover 2 into a periphery thereof. The plane O ring 7 is provided with the through hole 9 for inserting of the rotating axle 14 provided to a center thereof and the hook section 7 which is inserted and fixed to the recess 6 of a connection of the base 3 which is provided to an outer periphery. |
