PROBLEM TO BE SOLVED: To solve the problem on a conventional bearing structure in which a rotating shaft is slid at total three points, one face in contact with a pressure spring and two faces of a V-shaped groove, that a bearing portion has great friction loss and a lower rotating speed, greater power consumption or the degradation of reliability on continuous or intermittent switching operation are caused by the greater friction loss of the bearing portion at a mechanical light switch. SOLUTION: In this bearing structure for supporting a rotating shaft rotatable in a V-shaped groove, a fixing member is provided at a position opposite to the V-shaped groove and an elastic member flexible in a plane perpendicular to the rotating shaft has one end fixed to the fixing member and the other end thrusting the rotating shaft at the side opposite to the V-shaped groove while following the rotating shaft with its rotating oscillation without slipping.
