Abstract
An attachment/detachment mechanism for an antenna is configured to avoid damage to the antenna when an excessively large force is applied to the antenna, regardless of the direction. A rotational L-shaped connector of an antenna section of the antenna is connected to an antenna housing disposed on a main electronic device unit. A fitting groove is formed on a male fitting cylinder on the rotational L-shaped connector side, and an O-ring is fitted to the groove. An engagement projection formed on an inner wall of a female fitting cylinder on the antenna housing frictionally engages with the O-ring. This configuration allows rotation and attachment/detachment of the antenna section relative to the antenna housing. A contact member is attached to the fitting cylinder to contact a contact spring 31 that presses the O-ring against the engagement projection.
