  In the present embodiment, the sun visor main body 3 is retracted, and the main body retaining protrusion 33 and the body recessed section 3e are located at different positions along the circumferential direction of the insertion section 5A, and the support retaining protrusion 31 and the support recess 27h Are at different positions along the circumferential direction of the insertion portion 5A. For this reason, the sun visor main body 3 can be more reliably prevented from being detached from the support shaft 5 at the storage position.

  In the present embodiment, the sun visor main body 3 is used at a position where the main body retaining protrusion 33 and the main body recessed portion 3e are at different positions along the circumferential direction of the insertion portion 5A, and the support retaining retaining protrusion 31 and the support recessed portion 27h Are at different positions along the circumferential direction of the insertion portion 5A. For this reason, it is possible to more reliably prevent the sun visor body 3 from coming off the support shaft 5 at the use position (the front use position and the side use position).

  In the present embodiment, the support member 25 includes a leaf spring 29 that presses the support shaft 5 in the radial direction between the main body retaining protrusion 33 and the support retaining protrusion 31. The leaf spring 29 is supported when the sun visor body 3 moves in the removal direction with respect to the support shaft 5, and the support retaining protrusion 31 destroys the shaft support 27 b 1 of the support member body 27. Is provided with a leaf spring edge 29e (FIG. 5) that prevents the sun visor body 3 from coming off from the support shaft 5. For this reason, even if both the flanges 6f and 7f of the sun visor body 3 with which the main body retaining projection 33 abuts and the shaft support portion 27b1 of the support member body 27 with which the support retaining projection 31 abuts are damaged. Since the support retaining protrusion 31 and the leaf spring edge 29e abut, the retaining function can be maintained.

  As mentioned above, although embodiment of this invention was described, these embodiment is only the illustration described in order to make an understanding of this invention easy, and this invention is not limited to the said embodiment. The technical scope of the present invention is not limited to the specific technical matters disclosed in the above embodiment, but includes various modifications, changes, alternative techniques, and the like that can be easily derived therefrom.

  For example, the main body retaining convex part 33 and the support retaining convex part 31 do not necessarily have to be provided at positions separated by 90 degrees in the circumferential direction.

  In the example of FIGS. 1 and 2, the main body retaining convex portion 33 is displaced in the circumferential direction with respect to the main body concave portion 3e in both the storage position and the use position, and the support retaining retaining convex portion 31 is opposed to the support concave portion 27h. Is displaced in the circumferential direction. However, in either one of the storage position and the use position, the main body retaining projection 33 is displaced in the circumferential direction with respect to the body recess 3e, or the support retaining projection 31 is displaced in the circumferential direction with respect to the support recess 27h. Either state may be used.

  The retaining function by the two retaining structures provided with the main body retaining convex part 33 and the support retaining convex part 31 is not limited to when the occupant pulls out the sun visor body 3 from the support shaft 5. For example, even when some impact load acts in the direction in which the sun visor body 3 is pulled out from the support shaft 5, it functions effectively.
