PROBLEM TO BE SOLVED: To provide a pivotal opening or closing mechanism for a vanity mirror lid installed at an automobile sun visor having a simple configuration and capable of holding a vanity mirror lid stably in its closed position and opened position even if the lid is opened and closed many times. SOLUTION: A lid 10 is made such that a substantial column-like pivot protrusion 11 protruded in a lateral direction and formed on its upper edge is rotatably inserted into and attached to shaft supporting grooves 23 formed at a mirror casing 20 attached to a frame 40 while engagement claws 21 are being engaged with engagement holes 45. A protrusion 48 is formed at a position where inner cores 42 of a frame 40 abut against the pivot protrusion 11. A first chamfered part 11a of the pivot protrusion 11 is formed at a position where it makes a surface contact with the extremity end surface of the protrusion 48 under a state in which the lid 10 is placed at the closed position, and a second chamfered part 11b of the pivot protrusion 11 is formed at a position where it makes a surface contact with the extremity end surface of the protrusion 48 under a state in which the lid 10 is placed at the opened position.
