In order to insert and support the shaft 4, front and rear bearing portions 3a,
A shaft hole 6 is formed in each of the shafts 3b, and the shaft 4 is inserted into the shaft hole 6.

Further, in order to prevent the shaft 4 from falling out of the holder 3, a drop-out preventing projection 4a is formed at the tip of the shaft 4 so as to project outward in the radial direction.
When inserting into the shaft hole 6 of the holder 3, the shaft 4 is inserted into the holder 3 by allowing the slip-out preventing projection 4a to pass through the groove portion 6a provided in the shaft hole 6.

Then, after inserting the shaft 4 into the shaft hole 6 of the holder 3, as shown in FIG. 15, the shaft 4 is rotated about 180 ° around the shaft center so that the protrusion 4a for preventing the slip-out is formed in the groove 6a. And is engaged with the projection contacting portion a indicated by hatching in FIG. At this time, the protrusion 4a for preventing the falling
16 prevents the shaft 4 from coming off due to a catching margin shown by reference numeral d in FIG.

By the way, as a recent tendency, in order to enhance the safety protection of occupants, various types of airbags are installed in vehicles, and in particular, curtain type airbags arranged along a side roof garnish from a front pillar. As shown in FIG. 13, in the vehicle type equipped with 7, the sun visor 1 is heavily loaded in the direction indicated by F in FIG. 13 when the curtain-type airbag 7 is activated.

The load F applied when the curtain-type airbag 7 is actuated causes a force to act in a direction in which the shaft 4 falls off the sun visor body 2. Therefore, in order to prevent the shaft 4 from falling off, by mounting the E-ring so as to bite into the groove of the holder 3 and the shaft 4, the curtain-type airbag 7 is temporarily operated and the shaft 4 falls off from the sun visor body 2. Even if a load F is applied in the direction, the shaft 4 is prevented from coming off as much as possible.
