A valve opening and closing timing control device includes: a driving-side rotating body synchronously rotated with a crankshaft of an engine and having a lid member fixed in a direction of the rotational axis; a driven-side rotating body integrally rotated with a camshaft for opening and closing a valve on the same rotational axis; a lock mechanism having a lock member moving in the direction and a lock recessed portion formed inside the lid member and into which the lock member is able to be fitted; and a torsion spring disposed outside the lid member and exerting a biasing force to the driving-side and driven-side rotating bodies, wherein a restricting projection portion for restricting a movement of the torsion spring in the direction is formed in the lid member.
