[0006]

In the sun visor for a vehicle constructed as described above, when the sun visor main body is disposed at the retracted position along the ceiling surface of the passenger compartment, the sun visor is formed by the engaging force between the engaging surface of the horizontal shaft and the engaging member. The main body is held in the storage position. The sun visor body in the storage position is rotated around the axis of the horizontal shaft body against the engaging force between the engagement surface and the locking member, so that the sun visor body is in a front light shielding position along the windshield. Be placed. The sun visor body at the front light blocking position is rotated together with the support shaft around the axis of the longitudinal axis of the support shaft, so that the sun visor body is located at the side light blocking position along the side glass.

In a state where the sun visor main body is disposed at the side light blocking position, the sun visor main body is appropriately pulled out in the axial direction of the horizontal shaft, so that light incident from the side glass is optimally shielded. When the sun visor body is pushed into the horizontal shaft, the sun visor body is placed at the original pushing position.

As the sun visor body is pulled out and pushed into the horizontal shaft, a sliding frictional force is generated between the outer peripheral surface of the horizontal shaft and the locking member. Then, the locking member is moved in a direction away from the outer peripheral surface of the horizontal shaft body while swinging the pair of rockers in the same direction, so that an excessive slippage occurs between the horizontal shaft portion and the locking member. No frictional force occurs.
