There are some that are disclosed in the publication.

As shown in Figure 5, this is the sun visor body a.
A metal case d comprises a metal case d, to which the frame b is fixed, and a fitting that is rotatably held on the sun visor arm c around its axis.
The sun visor body a is attached to the sun visor arm c through the sun visor arm c.

(Problem to be solved by the invention) However, in the above conventional example, the rotational position of the bearing member f and the sun visor body a for holding the metal case d on the sun visor arm c so as to be rotatable around its axis is determined. Since it is necessary to provide special members such as a member for attaching the parts, there is a problem that the number of parts increases.

In addition, in order to hold the metal case d on the sun visor arm c, the sun visor arm c is attached to the bearing member f.
In order to press-fit the frame b into the metal case d or to fix the frame b to the metal case d, it is necessary to perform welding S, etc., which increases the number of assembly steps and increases costs.

(Means for Solving the Problems) In order to solve the above problems, the present invention fixes the frame of the sun visor body and uses a mounting fixture that is held rotatably around its axis on the sun visor arm. In the automobile sun visor in which the sun visor body is attached to the sun visor arm, the mounting fixture is constituted by a two-part type resin case in which the front plate and the rear plate are connected at the upper side by an integral hinge, and the resin case is A fixing part that clamps and fixes the frame when closed, a bearing part that rotatably supports the sun visor arm, and a rotary positioning piece that comes into elastic contact with the sun visor arm are integrally formed on the resin case, and The present invention is characterized in that it includes a fixing means for fixing the resin case in a closed state.

(Function) According to the above configuration, the mounting tool for attaching the sun visor body to the sun visor arm is constructed of a resin case, and the bearing portion rotatably supports the sun visor arm, and Since the rotary positioning piece that can perform rotational positioning with respect to the sun visor arm is integrally formed with the resin case, there is no need to provide special members such as bearing members as in the conventional example, and the resin case can be used as a sun visor arm. The arm can be held so as to be rotatable around its axis and positioning in the rotational direction is possible.

As a result, it is possible to reduce the number of parts and reduce costs.

In addition, the resin case is formed into a two-part type in which the front plate and the rear plate are connected at the upper side by an integral hinge, and the fixing part for fixing the bearing part and the frame of the sun visor body is formed into the front plate and the rear plate, respectively. Since the resin case is divided into two parts, the work of holding the resin case on the sun visor arm and the work of fixing the frame to the resin case are performed by placing the sun visor arm and frame at positions corresponding to the bearing part and fixing part of the resin case, respectively. This can be done all at once by closing the resin case in a state where it is once held, and fixing the resin case in the closed state using a fixing means.

As a result, the number of assembly steps can be reduced, and processing such as welding can be made unnecessary, so that together with the reduction in the number of parts, it is possible to further reduce costs.
