Structure for holding functional device

A structure for holding a functional device in a passenger compartment of a vehicle, the structure comprising:

• a switchboard arranged on a panel in the passenger compartment, wherein the switchboard includes a functional device;
• an accommodating case arranged adjacent to the switchboard;
• a holder for holding the switchboard and the accommodating case in the panel;
• a common shaft shared by the switchboard and the accommodating case and pivotally supporting the switchboard and the accommodating case, wherein the switchboard and the accommodating case are each pivoted about the common shaft between a retracted position and an operational position, the switchboard and the accommodating case each being accommodated in the panel when located at the retracted position and being exposed from the panel when located at the operational position, wherein the switchboard remains at the retracted position when the accommodating case is located at the operational position;
• a first spring connecting the switchboard and the accommodating case to each other and urging the accommodating case toward the operational position, wherein the first spring pivots the accommodating case integrally with the switchboard when the switchboard is pivoted between the retracted position and the operational position;
• a second spring for connecting the switchboard and the holder to each other and urging the switchboard toward the operational position;
• a lever connected to the switchboard and having an engaging pin;
• a cam pivotally supported on the holder and having a guide groove that engages the engaging pin;
• a third spring for urging the cam in a predetermined direction to arrange the switchboard at the operational position, wherein the third spring engages the engaging pin with the guide groove to hold the switchboard at the retracted position, and wherein, when the lever is moved against the urging force of the third spring, the engaging pin is disengaged from the guide groove and the urging force of the second spring moves the switchboard to the operational position;
• and
• a restriction pin arranged on the accommodating case, wherein the restriction pin contacts the cam and restricts the disengagement of the engaging pin from the guide groove of the cam when the accommodating case is located at the operational position.
