Abstract: A control adapter device for attaching to a control unit having an input control part is disclosed. The control adapter device includes a connector for electrically connecting the control adapter device to the control unit, a transmission part for transmitting, by wireless transmission, a signal that is input from the input control part, a case supporting the connector and containing the transmission part therein, an engagement member being supported by a shaft in the case for rotatable movement between an engagement position and a disengagement position, the engagement member being formed to engage the control unit, and including a press-maneuver part for receiving a pressing force to thereby rotate the engagement member, and a restriction member being disposed in the case to block movement of the press maneuver part of the engagement member, and thereby restrict movement of the engagement member beyond the disengagement position.
