To enable a rounded curved design, to reduce the number of parts and to simplify a manufacturing process by installing a molded pin to the external surface of the closed end section of a barrel integrally formed to a cover, arranging a spring, a cam and a follower on the inside and mounting the spring, the cam and the follower into recessed sections formed by the left and right shoulders of a main body.
In an openable portable radio communication device, a molded pin 127 is mounted on the surface of the closed end section of a barrel 124 integrally molded to a cover 104, a spring 116, a cam 118 and a follower 120 are inserted into the barrel 124, the flat front of the cam 118 is combined with the spring 116, and a follower head is united with the curved surface of the cam 118. In a recessed section 103, in which edges are formed by the left and right shoulders of a main body 102, the molded pin 127 is received in a cavity in the left shoulder, the positioning rib 130 of the follower 120 is received in a cavity 107 in the right shoulder 111, the follower 120 is introduced to a specified place, and the cover is locked by force transmitted through the cam 118 from the spring 116 while force transferring from an open place to a closed place is worked.
