In such a door mirror, each wire is inserted into a tube, passed through the inside of a base fixed to the door, and the inside of a hollow fixed shaft erected on this base, and guided into the mirror housing from an operating rod. Each wire slides within the tube and tilts the mirror body by a pulling operation.

<<Problems to be solved by the invention>> By the way, since the hollow part of the fixed shaft through which each wire is inserted communicates the inside of the mirror housing and the inside of the base, rainwater etc. can enter into the base from the mirror housing. There is a possibility that Therefore, it is necessary to close the opening of the fixed shaft.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the door mirror of the present invention connects a plurality of wires to a mirror that is tiltably supported by a support member in a mirror housing. This is a door mirror that adjusts the tilting of the mirror by pulling these wires with an operating rod placed inside the vehicle, and each of the wires is inserted into a tube and is attached to the inside of a base fixed to the door and to the inside of this base. The cap is guided into the mirror housing from the operating rod through the interior of the hollow fixed shaft that is erected, and a cap having an insertion hole for each wire is fitted into the opening of the fixed shaft, and the supporting member Further, an extended retaining portion is formed on the surface of the cap.

<<Operation>> By fitting the cap onto the fixed shaft, the opening of the fixed shaft can be closed very easily. Furthermore, by assembling the support member to the fixed shaft, the retaining portion faces the surface of the cap, thereby preventing the cap from coming off.

<<Example>> FIG. 1 is a schematic exploded perspective view showing a door mirror according to an example of the present invention.

This door mirror is a foldable type that can be folded onto the side of the vehicle body, and is rotatably assembled to a base 2 that is fixed to the side of the door via a gasket 1 and a fixed shaft 3 provided on this base 2. supporting member 4
a mirror housing 5 attached to and covering the support member 4; a mirror body base 6 attached to the support member 4 so as to be tiltable via a pivot mechanism; and a mirror body base 6 detachably attached to the mirror body base 6. It has a mirror body 7 and a mirror 8 that is fitted and held on the mirror body 7 via a cushion material (not shown), and three wires 9a, 9 connected to the mirror body base 6.
The tilting of the mirror 8 is adjusted by pulling and operating the levers b and 9c using an operating rod 10 attached to the base 2.

The base 2 has a cavity formed therein for wire insertion, and the fixed shaft 3 also has a wire insertion hole 3a. The wires 9a, 9b, 9c connected to the operating rod 10 are inserted into the tubes 37a, 37b, 37c, respectively, and are passed through the inside of the base 2 and the wire insertion hole 3a of the fixed shaft 3 to the support member 4 side. I'm starting to be guided by this.

The support member 4 includes a die-cast main bracket 11 and a resin sub-bracket 12.

The main bracket 11 has a cylindrical portion 13 formed at the folding center of the door mirror.
As shown in FIG. 2, the fixed shaft 3 on the base 2 side is inserted into this cylindrical portion 13, and a push nut 29 is attached to the inserted end via a coil spring 14, so that it can be rotated freely on the base 2. It is assembled into. In detail, a flange portion 15 is formed at the base end of the fixed shaft 3, and the main bracket 11 is received on this flange portion 15. A regulating mechanism is provided between the upper surface of the flange portion 15 and the lower surface of the main bracket 11 to hold the main bracket 11 at a predetermined rotational position. In other words, this regulating mechanism is configured such that a plurality of rollers 16 attached to the main bracket 11 are elastically fitted into a plurality of grooves 17 formed in the flange portion 15, so that the main bracket 11 is rotated within a predetermined range. When in this position, each roller 16 fits into a groove 17 to restrict rotation of the main bracket 11.

In addition, each wire 9 is attached to the main bracket 11.
A mechanism is provided to prevent loosening of a, 9b, and 9c. This mechanism has a coil spring 1 attached to a guide post 18 formed on the main bracket 11.
The wire pressing body 20 is fitted through the wire pressing body 20, and the wires 9a, 9b, and 9c are hooked onto the wire sliding contact portion 21 formed at the tip of the wire pressing body 20, and the coil spring 19 is elasticized. Tension is applied to each wire 9a, 9b, 9c by force. In addition, in detail, the wires 9a, 9
As shown in FIG.
guided by c.

By the way, in this embodiment, each wire 9a, 9
A common wire pressing body 20 and coil spring 19 are provided for wires 9a, 9b, and 9c.
9c may be individually energized. Further, in this case, for example, in order to simplify the structure, it is also possible to adopt a structure in which a single plate spring serves both the wire pressing body and the spring. That is, the leaf springs are provided in correspondence with the number of wires, each having a curved distal end to form a wire sliding contact part, and the resilient force of the leaf spring urges each wire individually. As a result, appropriate tension can be obtained for each wire, and a more reliable effect of preventing loosening can be obtained. Note that the main bracket 11 is formed with a guide stepped portion 23 for the wire pressing body 20. As shown in FIG.

Further, the sub-bracket 12 is fixed to the main bracket 11 with screws, and is integrally formed with a cover 30 for covering the wire sliding contact portion 21, and supports the mirror body base 6 on the front surface. A pivot mechanism is arranged.

The cover 30 has a structure that surrounds the wire pressing member 20 from three sides, overlaps the upper edge of the main bracket 11, and covers the upper surface of the wire sliding contact portion 21. This prevents dust and the like from entering the wire sliding contact portion 21.

A portion of the cover 30 is extended downward to form a cap 3 attached to the opening of the fixed shaft 3 described above.
It faces the top surface of the cap 1 and serves as a retaining portion 32 for the cap 31. That is, the cap 31 is fitted into the open end of the fixed shaft 3, and each wire 9
Three insertion holes 3 for inserting a, 9b, 9c
1a, 31b, and 31c, and is provided with a flange portion 33 at the base end, and this flange portion 33
The tip of the retaining portion 32 is close to. With this structure, the cap 31 can be easily attached to the fixed shaft 3, and the attached cap 31 can be easily attached to the fixed shaft 3.
1 should come off from the fixed shaft 3, the retaining portion 32 can prevent it from falling off.

On the other hand, the pivot mechanism, as shown in Figure 6,
The annular fitting portion 24 formed on the mirror body base 6 is connected to the receiving portion 2 formed on the sub-bracket 12.
5 and a pressure contact member 26 inserted through a hole 6a formed in the center of the mirror body base 6 and attached to the receiving portion 25. That is, the fitting portion 24 has a convex spherical outer periphery, is slidably in close contact with the concave spherical surface formed on the receiving portion 25, and a part of the inner periphery has a convex shape formed on the outer periphery of the pressure contact member 26. It has a structure that allows it to slide freely against the spherical surface. The pressure contact member 26 is screwed to the receiving portion 25 side. As a result, the fitting part 24 is held between the receiving part 25 and the pressing member 26, and is held movably with each spherical surface as a guide, and the mirror body base 6 is supported so as to be tiltable.

The mirror body base 6 supported in this manner has a locking portion 3 for attaching the mirror body.
A plurality of numbers 4 are formed. This locking part 34 has a shaft body 34a integrally formed in a notch formed in the mirror body base 6, and as shown in FIG. The pieces 35 are adapted to fit together.
As a result, the mirror body 7 is detachably attached.

Further, as shown in FIGS. 3 and 6, the mirror body base 6 and the main bracket 11 are integrally formed with contact portions 50a and 50b for regulating the tilting position of the mirror body base 6. These contact portions 50a and 50b each have an annular protrusion shape, and are formed opposite to each other.
When the tilting angle of the mirror body 7 exceeds a certain level, the mirror body 7 comes into contact with the mirror body 7 to limit its tilting. This restricts unnecessary tilting of the mirror body base 6, and allows the mirror body 7 to be easily attached and detached.

Further, each wire 9a, 9b, 9c has one end locked to a locking member 36 provided at the base end of the operating rod 10, and has tubes 37a, 37b, 3, respectively.
7c is inserted into the base 2 and the fixed shaft 3, and is inserted into the insertion hole 31a of the cap 31 described above.
31b and 31c, the wire is guided to the sliding contact part 21, and further passed through each insertion hole of the sub-bracket 12 and mirror body base 6, and the other end is connected to the connecting plate 38.
It is now being joined to.

The connecting plate 38 is held on the front surface of the mirror body base 6 by the tension of each wire 9a, 9b, 9c. Therefore, by tilting the operating rod 10, the wires 9a, 9b, 9c are selectively pulled, and the connecting plate 38 is tilted together with the mirror body base 6. This allows the angle of the mirror 8 to be adjusted.

Moreover, each tube 37a, 37b, 37c is flexible and guides each wire 9a, 9b, 9c slidably. Of each tube 37a, 37b, 37c, the portion disposed inside the base 2 is attached to a holding member 3 attached to the inner wall of the base 2, as shown in FIGS. 2 and 7.
9, they are clamped and fixed in parallel and in close contact with each other. By this, each tube 37
a, 37b, 37c are wires 9a, 9b, 9c
Proper operating conditions can be maintained without loosening during operation.

Furthermore, each tube 37a, 37b, 37
As shown in FIG. 8, the portions c of the fixed shaft 3 arranged in the wire insertion hole 3a are arranged in a state of being bound together due to the shape of the wire insertion hole 3a. In other words, the wire insertion hole 3 of the fixed shaft 3
a is formed into a substantially equilateral triangle, and each tube 37 is placed at each vertex of the triangle according to this shape.
a, 37b, and 37c are arranged and held in substantially close contact with each other. This prevents each tube 37a, 37b, 37c from loosening within the fixed shaft 3, and improves the transmission efficiency by the wires 9a, 9b, 9c.

Further, as shown in FIG. 2, the operating rod 10 has a knob 40 press-fitted into its distal end, and a washer 41 and a locking member 36 press-fitted into its proximal end. The locking member 36 is formed to bulge in the outer diameter direction of the operating rod 10, and the wires 9a, 9b, 9c are inserted into the three locking holes 42 formed from the tip to the proximal end of the operating rod 10. Sphere 43 formed at the tip
It is designed to be locked and held. As a result, each wire 9a, 9b, 9c is connected to the operating rod 1.
Connected to 0.

Further, the washer 41 is disposed near the tip of the operating rod 10 with respect to the locking member 36, and has a shape that partially closes each locking hole 42 of the locking member 36. As a result, the sphere 4 in each locking hole 42
3, the operation rod 10 is prevented from disengaging in the distal direction, and the operation rod 10 is reliably displaced by the tilting operation, so that an appropriate transmission action of the wires 9a, 9b, and 9c can be obtained. ing.

Further, the washer 41 is formed with a fitting portion 44 that is inserted into the operating rod insertion hole 1a of the packing 1. That is, the fitting part 44 is formed by forming an annular groove part 44a on the outer periphery of the shaft part formed in the washer 41, and the peripheral part of the operating lever insertion hole 1a of the packing 1 is inserted into the groove part 44a and held. , so as to close the operating rod insertion hole 1a. Further, the area around the operating rod insertion hole 1a of the packing 1 is formed into a cylindrical bulge, making it highly flexible. Therefore, even when the operating rod 10 is tilted, it can be freely followed, and the insertion hole 1a and the fitting portion 44 will not separate. By the way, the operating rod insertion hole 1a
is formed to have a large diameter to accommodate the insertion of the knob 40 of the operating rod 10, but it is reliably closed by the washer 41, so that the seal 1 can maintain a watertight state. It's summery.

<<Effects of the invention>> As explained above, according to the invention, by fitting a cap having a wire insertion hole to the fixed shaft through which the wire is inserted, the opening of the fixed shaft can be easily closed. , it is possible to ensure watertightness of this part. Furthermore, the retaining portion provided on the support member can prevent the cap from detaching from the fixed shaft.
