  Then, this invention makes it a subject to provide the accessory attachment structure of the sun visor for vehicles which can hold | maintain an accessory strongly to a visor main body.

  In order to solve the above-mentioned problems, the present invention is an accessory mounting structure for a vehicle sun visor having a configuration as described in each claim. That is, according to the first aspect of the present invention, the plate-like bracket provided on the visor main body side, the mounting member provided on the back surface of the bracket, and the front side of the accessory provided on the surface of the bracket. And a threaded member. At least one member of both the attachment member and the screwing member is provided with a shaft portion that penetrates the bracket and the accessory and is screwed with the other member, and the accessory is attached by the attachment member and the screwing member. It is configured to be mounted on the bracket side.

  Therefore, the accessory is attached to the bracket by the attachment member and the screwing member. And an accessory is prevented from dropping with respect to a bracket by the attachment member installed in the back surface of the bracket. Thus, the accessory can be held firmly on the visor body. The shaft portion has a male screw portion on the outer peripheral surface and the other member is screwed to the male screw portion, and has a female screw portion on the inner peripheral surface and the other member screwed to the female screw portion. Also good.

According to the first aspect of the present invention, the bracket is formed with an elastic claw for elastically deforming and holding the mounting member on the back side of the bracket. Therefore, the attachment member can be easily attached to the bracket by the elastic claw.

According to the first aspect of the present invention, the bracket is formed with a holding portion that protrudes from the back surface of the body portion of the mounting member and prevents the mounting member from falling off the bracket, and a cantilever-like elastic claw. Yes. Then, the elastic claw is elastically deformed in the thickness direction of the bracket by the main body portion of the mounting member, and the mounting member is rotated around the shaft portion formed on the mounting member or the screwing member, whereby the main body portion is moved to the front side of the holding portion. Inserted. The elastic claw is elastically returned and protrudes to the side of the main body, and the elastic claw prevents the main body from rotating.
