The lock switch is connected so as to control an external circuit. The antenna has a core section and a conducting wire. The core section is installed, with a gap between itself and the lock switch, such that it deflects and deforms by being grasped by an operator, pushing down the lock switch, and is formed from a soft magnetic body. The conducting wire is wound on the core section, connected to the external circuit, for communication with an external portable device through a radio wave.
