Abstract

PROBLEM TO BE SOLVED: To prevent the play of a mirror housing. SOLUTION: A shaft support 400 is formed of wear resistant hard synthetic resin, separately from a mirror housing 300. As a result, even is if the mirror housing 300 is formed of relatively soft synthetic resin, the shaft support 400 which is formed of wear resistant hard synthetic resin, separately from the mirror housing 300, can be increased in strength without being increased in thickness. The sink of synthetic resin molding is restricted and the deformation of the shaft support 400 is prevented, so that a transparent hole 401 in the shaft support 400 is easily centered, a contact plane between the inner face of the transparent hole 401 in the shaft support 400 and the outer face of the axis 201 of a shaft 200 is increased and the mirror housing 300 is firmly mounted to the shaft 200 without a play.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mirror housing, such as a door mirror, which is rotatably mounted on a shaft of a mirror base. Also, the present invention relates to a retractable rearview mirror for a vehicle, which can be rotated and tilted from the front side or the opposite side to the use position, and in particular, the mirror housing can be securely attached to the mirror base shaft without play. The present invention relates to an inverted vehicle rearview mirror.

[0002]

2. Description of the Related Art A conventional retractable rearview mirror for a vehicle will be described below with reference to FIGS. The illustrated rearview mirror for a vehicle is a rearview mirror for a vehicle mounted on the left side of the automobile (left side when the driver looks forward). In the figure, 1 is a mirror base. This mirror base 1
Is a hollow, substantially rectangular parallelepiped base portion 10 made of, for example, a synthetic resin and having a substantially horizontal and open upper surface 13.
And a substantially vertical and substantially triangular fixing portion 11 are integrally formed. The fixing portion 11 is fixed to a vehicle body, for example, a door (not shown). The shaft 2 is fixed to the upper surface opening 13 of the base part 10 by a screw 12.

[0003] The shaft 2 is made of, for example, metal (die-cast), and a flange portion 21 is integrally provided at one end (lower end) of a shaft portion 20 having a circular cross section. This collar 21
Are provided with a plurality of recesses 22 on the upper surface thereof. The outer diameter of the root portion of the shaft portion 20 of the shaft 2 with the flange portion 21 is larger than that of the other portions. A mirror housing 3 is rotatably mounted on the shaft 2.

[0004] The mirror housing 3 is made of, for example, ABS.
It is made of a relatively soft synthetic resin such as a resin, and has a hollow shape having an opening 30 on the front surface. A shaft receiving portion 31 of a boss portion is integrally provided on one end side of the bottom portion of the mirror housing 3, and a circular stepped through hole 32 is provided in the upper portion 31 of the shaft. This shaft receiving portion 31
Is provided with a plurality of concave portions 33, and the steel balls 23 are rotatably mounted in the concave portions 33.
A mirror unit 34 is provided in the mirror housing 3.
Can be tilted up and down and left and right by manual control directly through a pivot mechanism (not shown), or can be tilted up and down and left and right by remote manual control via wires and controller knobs (not shown) Or by a remote control via a power unit mechanism (not shown) so as to be tiltable in the vertical and horizontal directions. The mirror unit 34 includes a mirror body having a reflection surface on the front side, and a back plate disposed on the back side of the mirror body.

The shaft 2 fixed to the mirror base 1 is inserted into a through hole 32 of a shaft receiving portion 31 of the mirror housing 3.
A push nut 24 is fixed to the shaft portion 20 of the shaft 2 and a coil spring 25 is interposed between the lower surface of the push nut 24 and the upper surface of the boss portion 31 of the mirror housing 3 in a compressed state. Let it.
As a result, the mirror housing 3 is rotatably attached to the shaft 2 fixed to the mirror base 1 by the elastic return force of the coil spring 25. The push nut 24 and the coil spring 25 constitute mounting means for rotatably mounting the mirror housing 3 to the shaft 2.

When a force is manually applied to the mirror housing 3 from the use position (set position) to the near side or the opposite side, the ball 22 on the mirror housing 3 side causes the shaft 22 to move.
(At this time, the mirror housing 3 is slightly away from the mirror base 1 and the shaft 2 against the spring force of the coil spring 25 (the ball 22 is moved away from the recess 22). The mirror housing 3 is rotated and tilted toward or away from the use position (set position) from the use position (set position) (at this time, the ball 22 rolls on the upper surface of the flange portion 21 of the shaft 2). ). When a force is manually applied to the mirror housing 3 from the near side or the opposite side to the use position (set position),
The mirror housing 3 is turned and tilted from the near side or the opposite side to the use position (set position) (at this time, the ball 22 rolls on the upper surface of the flange 21 of the shaft 2), and the ball 22 enters the recess 22. Then, the mirror housing 3 is again located at the use position. Thus, the mirror housing 3 is
It is possible to rotate and tilt manually from the use position (set position) to the near side or the opposite side and from the near side or the opposite side to the use position.

In such a rearview mirror for a vehicle, it is important that the mirror housing 3 is firmly attached to the shaft 2 without play, to prevent chattering of the mirror (mirror surface), and to improve durability against vibration of the automobile. It is. In addition, the entire weight of the mirror housing 3 is applied to the inner surface of the through hole 32 of the shaft receiving portion 31 that comes into contact with the outer surface of the shaft 2.
It is necessary to increase the strength of the shaft receiving portion 31 in consideration of durability, that is, the above-mentioned play.

[0008]

However, in the above-mentioned conventional rearview mirror for a vehicle, the shaft receiving portion 31 is provided integrally with the mirror housing 3 made of a relatively soft synthetic resin. In order to increase the strength of the receiving portion 31, it is necessary to increase the thickness of the shaft receiving portion 31. When the thickness of the shaft receiving portion 31 is increased,
The sink of synthetic resin molding is easily generated. When sink occurs,
The shaft receiving portion 31 is deformed, and it is difficult to center the circular through hole 32 of the shaft receiving portion 31 (to make the circular through hole 32 a perfect circle), and the inner surface of the through hole 32 of the shaft receiving portion 31 is difficult. There is a problem that the contact surface between the shaft and the outer surface of the shaft 2 is reduced, and rattling is likely to occur.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a rearview mirror for a vehicle which can securely mount a mirror housing on a shaft without play.

[0010]

In order to achieve the above-mentioned object, the present invention is characterized in that the shaft receiving portion is made of a wear-resistant hard synthetic resin separate from the mirror housing.

As a result, in the rearview mirror for a vehicle according to the present invention, even if the mirror housing is made of a relatively soft synthetic resin, the shaft receiving portion is made of a wear-resistant hard synthetic resin separate from the mirror housing. Therefore, the strength of the shaft receiving portion can be increased without increasing the thickness of the shaft receiving portion. Therefore, the occurrence of sink in synthetic resin molding can be suppressed, the deformation of the shaft receiving portion is prevented, the centering of the through hole of the shaft receiving portion is facilitated, and the inner surface of the through hole of the shaft receiving portion and the outer surface of the shaft are formed. The contact surface increases, and the mirror housing can be securely attached to the shaft without play.
