コスト高となる問題点があった。By the way, the mounting angle of the bracket 107 of the support shaft 101 with respect to the ceiling surface of the vehicle compartment and the posture state of the ceiling surface differ for each vehicle type. on the other hand,
The rotation angle of the sun visor main body 111 based on the spring force of the spring cylinder portion 132 of the locking spring 131 is narrow at around 10 to 15 degrees. For this reason, as shown in FIG. 22, when a sun visor having a bearing structure configured corresponding to a predetermined vehicle type is mounted on a ceiling surface 151 of a vehicle room of a different vehicle type,
As shown in FIG. 23, the sun visor main body 111 cannot be stored and held at the storage position in contact with the ceiling surface 151 of the vehicle interior, and only a gap is generated between the ceiling surface 151 of the vehicle interior and the sun visor main body 111. No, sun visor body 111
There is a case in which there is a problem that the backlash shakes unexpectedly. For this reason, in the conventional vehicle sun visor bearing structure, the support shaft 101 cannot be used in common, and the position of the locking surface 104 with respect to the outer peripheral surface of the horizontal shaft portion 103 is different. Must be produced respectively,
There was a problem that the cost was high.

てあることを特徴とする。In order to achieve the above object, a bearing structure for a sun visor for a vehicle according to the present invention comprises a bearing case in which a horizontal shaft portion of a support shaft is rotatably inserted. A vehicle configured such that the provided sun visor body is rotated around the axis of the horizontal shaft portion to be switched between a storage position in contact with a vehicle interior ceiling surface and a light shielding position along a windshield. Bearing structure for a sun visor for use, wherein first and second locking surfaces are provided in the axial direction on the outer peripheral surface of the horizontal shaft portion, while the first and second locking surfaces are provided in the bearing case. 2
Locking spring means having first and second spring portions each having an engaging surface individually engaged with both locking surfaces of the horizontal shaft portion is assembled. When the sun visor body is rotated to a position immediately before the storage position, first, the engagement surface of the first spring portion is connected to the horizontal shaft. The sun visor body is rotationally urged to a position where the sun visor body is engaged with the locking guide surface of the first locking surface of the portion, and subsequently, the engagement surfaces of the first and second spring portions are the same as those of the horizontal shaft portion. The sun visor main body is rotationally biased in a direction in which the sun visor main body is engaged with the first and second locking surfaces, and the sun visor main body is rotated to the storage position.

できる。Therefore, the sun visor body is rotated to a position immediately before the storage position where the sun visor body comes into contact with the ceiling surface of the passenger compartment, and
When the engaging surface of the spring portion approaches a position at a predetermined angle with respect to the locking guide surface of the first locking surface of the horizontal shaft portion, first, the first
The sun visor body is rotated toward the storage position by the spring force of the spring portion. Then, after the engagement surface of the first spring portion comes into surface contact with the engagement guide surface of the first engagement surface of the horizontal shaft portion and engages, the sun visor body is subsequently moved to the storage position by the spring force of the second spring portion. It is turned toward. After disengagement of the surface contact between the engagement surface of the first spring portion and the locking guide surface of the horizontal shaft portion, each engagement surface of the first and second spring portions is moved to the first position of the horizontal shaft portion. First, the sun visor main body is rotationally biased in a direction in which the sun visor main body is individually engaged with the first and second locking surfaces. As described above, the rotation biasing angle of the sun visor body based on the spring forces of the first and second spring portions is continuously formed at a predetermined angle with respect to the first locking surface of the outer peripheral surface of the horizontal shaft portion. Enlarged by the formed locking guide surface. Therefore, even when the mounting angle of the bracket of the support shaft with respect to the cabin ceiling surface and the posture state of the ceiling surface are different for each vehicle type, the sun visor body must be securely disposed and held at the storage position in contact with the cabin ceiling surface. Therefore, it is possible to prevent a problem in which the sun visor body shakes unexpectedly.
