Traces the inside of the front half portion 41b of the heart-shaped cam groove 41 provided in the lifting operation member 3 (arrow in FIG. 7).

The sun visor is slightly diagonally upward beyond the horizontal,
The upper end of the elevating member 2 pushed up at its free end abuts on the ceiling wall 14 of the housing 12 (FIG. 8), and when the sun visor cannot be lifted any further, the hand is released from the sun visor. Then, the elevating member and the elevating member are lowered by the urging of the coil springs 7 and 8, respectively, and accordingly, the slide member retreats a little, and the sun visor pivots downward, but the sun visor is almost horizontally. When it is turned on (two-dot chain line in FIG. 8), the bent portion 42b at the lower end of the pin of the heart cam device is engaged with the locking portion located at the recess of the heart at the lower end of the heart-shaped cam groove 41.
In order to lock 41c, the lowering of the lifting / lowering operation member 3 stops, and accordingly, the slide member also stops retreating (FIGS. 10 and 11).
Figure). In this state, the front end of the slide member is still in the recess S 'at the free end of the sun visor, so that the sun visor is also prevented from rotating downward and is held in the retracted state, The member 2 is also pressed onto the upper surface of the sun visor by the coil spring 7 and stops descending.

To use the sun visor again, push up the free end of the sun visor which is held almost horizontally,
The lifting operation member is raised (FIG. 10, two-dot chain line). As a result, the bent portion 42b at the lower end of the pin 42 of the heart cam device is engaged with the locking portion 41 at the recess of the heart at the lower end of the heart-shaped cam groove 41.
It moves from c to the escape portion 41d (arrow in FIG. 11), and the inside of the rear half portion 41e of the heart-shaped cam groove 41 can be traced. Therefore, when the free end of the sun visor held horizontally is pushed up by one finger with a finger and then released, the elevating member 2 moves the coil spring 7
The downward movement of the sun visor causes the sun visor to be lowered, and the lifting and lowering operating member is lowered by the urging of the coil spring 8, whereby the slide member 5 is retracted by the inclined cam device 6 and its front end is moved to the free end of the sun visor. The sun visor is lowered vertically, the elevating member 2 is lowered until the tail 22 is received on the front half 51 of the slide member, and the lower end of the pin 42 of the heart cam device is removed. Bent part 42
6 traces the inside of the rear half portion 41e of the heart-shaped cam groove 41 toward the pointed starting portion 41a (FIG. 13), and the lifting / lowering operating member 3 descends until it is located at the pointed starting portion 41a. Return to the state.

<Effects of the Invention> As is apparent from the above, according to the present invention, when storing the sun visor or the like in use, the sun visor is pulled up slightly over the horizontal storage position and released by releasing the sliding member 5. The sun visor can be securely held in a horizontal storage state, preventing the stored sun visor from hanging down inadvertently due to vibration of the car body and blocking the field of view, and putting the stored sun visor in use state Requires only a slight push-up of the free end of the sun visor and does not require the need to manually pivot downward.

Further, when the sun visor is stored, the elevating member 2 is first pushed up by the sun visor, and after the elevating member 2 is slightly elevated, the slide member 5 is advanced to hold the sun visor in the storage position. The actuating member 3 starts to rise at the tail 22 of the lifting member. Thus, if the sliding member is moved forward as soon as the lifting member 2 is pushed up by the sun visor, the sliding member protrudes from the rotation trajectory of the free end of the sun visor and prevents the sun visor from being pulled up to the storage position. In addition, the appearance that the slide member 5 protrudes into the recess at the free end of the sun visor and holds the sun visor in the storage position is not visible from the outside, so that the appearance is good.
