摘要

Transmitter (10) has a flat-shaped operation body (2) has a convex portion (2a) accommodated in an upper case in a state in which the convex portion can be move vertically and protruding from the through hole of the upper case. A circuit board (3) is accommodated between operation body and lower case. A switch is mounted on the circuit board and below the convex portion. The sidewall elastically presses the operation body to the upper surface of the upper case. The switch is sealed in a spaced formed by the circuit board, side wall and operation body. Through hole is formed on the upper surface of the upper case. A lower case (4) has a sidewall extending in the direction of upper case and covering the lower surface of the upper case.
