[Detailed description of the invention] <Industrial application field> This invention is an electric remote control door mirror, particularly an electric remote control door mirror having a mechanism to securely hold a cord that electrically connects a drive unit that drives the mirror in a tiltable manner. Regarding remote control door mirrors.

《Prior Technology》 Conventionally, when a shock is applied to the mirror body, a door mirror with a shock absorbing mechanism that folds against the base to alleviate the shock is equipped with a drive unit for adjusting the mirror's field of view, and an electric An electrically operated remote control mirror is known that allows the user to make the adjustment at will. For such mirrors, it is necessary to wire the cord from the switch into the mirror body in a free state relative to the drive unit, so that the cord will not be damaged when the mirror body is tilted or become an obstacle when the mirror body is folded. Alternatively, as disclosed in Japanese Utility Model Application Publication No. 58-108936, a cord holding part and a fixed part are formed on a wire-like hook, and the fixed part is screwed into a mounting boss with a screw. It was configured to do so.

[Problems to be solved by the invention] However, in the former conventional technology, when attaching the door mirror to the vehicle body, the cord may become loose or move and come off from between the mounting base and the vehicle body attachment part, or the cord may become loose or move. The cord gets caught between the mounting base and the car body mounting part, making it difficult to assemble, and when the mirror body is folded down, the cord comes into contact with the periphery of the mounting hole in the car body mounting base, causing wear. There was a danger that the wires would break or break, causing electrical problems.

Further, the latter conventional technique has the problem that it requires a large number of parts and also increases the man-hours required for manufacturing the hook and assembling the screw.

The purpose of the present invention is to provide an electric remote control door mirror with a shock absorbing mechanism in which the cord that electrically connects the drive unit and the switch inside the mirror body is given slack in advance so that the cord can be easily installed. shall be.

<Means for Solving the Problems> In the present invention, a mirror and a mirror body supporting the mirror are arranged to be electrically tiltable within the mirror body, and the mirror body is attached to a mounting base with a coil. The door mirror is mounted by being crimped with a spring, and the vehicle body mounting surface of the mounting base is formed with a cord insertion hole, a plurality of vehicle body mounting bosses protruding toward the vehicle body, and a hook mounting boss. A predetermined amount of the cord is disposed and held within the mirror body by press-fitting and locking a locking portion of the hook, which is composed of a locking portion having a locking claw and a cord holding portion, on the hook attachment boss. It is characterized by

<Operation> This invention holds the cord by placing the cord inside the mirror body so that it has a certain amount of slack, and then press-fitting the locking part of the hook into the car body mounting boss formed on the car body mounting surface. The cord is held between the section and the base.

<<Example>> Hereinafter, an example of the present invention will be described with reference to the drawings. Fig. 1 is a partial sectional view showing an overview of the electric remote control door mirror of the present invention, Fig. 2 is a front view, Fig. 3 is a view taken in the direction of arrow A in Fig. 2, and Figs. 4 to 6 are It is a figure showing a hook. The mirror 1 is held by a mirror body 2, and the mirror body 2 is tilted about a pivot 31 by a drive member 32, and is connected to a drive unit 3.
is supported by 33 is a motor casing that covers a drive mechanism (not shown) of the drive unit.

A motor casing 33 that tiltably supports the mirror 1 is fixed to a bracket 42 attached to the mirror body 4 by a screw 34. The mirror body 4 is composed of a bracket 42 and a mirror housing 41 fixed to the bracket, and the mirror body 4 is crimped and held on the mounting base 6 by a coil spring 9.
That is, in the shock absorbing mechanism of the present invention, the shaft 51 at one end of the mirror body 4 is pivotally connected to the bracket 42 of the mirror body 4, and the shaft 52 at the other end is pivotally connected to the mounting base 6 via the hinge plate 5. The mirror body 4 is crimped and held on a mounting base 6. Therefore, in response to an impact from the rear side (front of the vehicle body) of the mirror main body 4, the mirror housing 41 is rotatable about the shaft 52 together with the hinge plate 5, thereby alleviating the impact. In response to an impact from the direction of the mirror, the mirror main body 4 is independently rotatable about a shaft 51, thereby alleviating the impact.

Further, a drive unit 3 fixed to the mirror body 4
A cord 7 electrically connects the mirror drive switch (not shown) located inside the vehicle body.
is guided through a space 44 formed in the lower wall 43 of the bracket 42 and a space 53 in the hinge plate 5 to a cord insertion hole 61 in the mounting base 6 via a grommet 62.

As shown in FIG. 3, the mounting base 6 is formed with three vehicle body mounting bosses 63 protruding toward the vehicle body arranged on a vehicle body mounting surface 60 in a substantially triangular shape with the cord insertion hole 61 at the center. At the same time, a hook attachment boss 65 is provided on the center side. A protective wall 64 is erected around the cord insertion hole 61 so as to be inscribed in the vehicle body mounting boss 63.
Further, around the cord insertion hole 61, as shown in FIGS. 4 to 6, a flat cord holding portion 81 and a locking hole 8 are provided on the mounting surface 60 side of the mounting base 6.
A hook 8 having a locking portion 83 is attached to the vehicle body mounting surface 60. This hook 8
is an oval-shaped flat cord holding part 81 and the holding part 81
It is provided with a columnar locking part 83 protruding from the
The locking portion 83 is provided with an arrowhead-shaped locking pawl 82 formed at an acute angle toward the tip, and these are integrally molded from synthetic resin. By pressing the cord 7 against the mounting surface 60 and press-fitting the locking portion 83 of the hook 8 into the hook mounting boss, the cord 7 is held between the vehicle body mounting surface 62 and the cord holding portion 81.

The door mirror is constructed by pressing and holding the mirror body 4 with the coil spring 9 via the hinge plate 5, and the three vehicle body mounting bosses 63 of the mounting base 6 are pressed against the inner peripheral edge of the door mirror mounting hole 11 of the vehicle body 10. They are arranged so as to be in contact with each other and are fixed to the vehicle body by screws 11a.

As a result of the above configuration, the cord 7 that electrically connects the drive unit 3 and a switch (not shown) for tilting the mirror inside the vehicle body is inserted into the mirror body 4 so that the mirror body 4 can be tilted by impact. Even in such cases, the cord 7 can be attached through the space 44 between the bracket 42 of the mirror body 4, the space 44 between the lower wall 43, and the space 53 of the hinge plate 5, after giving a certain amount of slack to the extent that the cord 7 will not be pulled excessively and cut. The cord is led out from the cord insertion hole 61 of the mounting base 6 to the outside of the door mirror, and is held down by the hook 8 inside a protection wall 64 that is vertically formed on the vehicle body mounting surface 60 of the mounting base 6. The hook 8 presses the locking portion 83 into the hook attachment boss 65 of the vehicle body attachment surface 60, thereby pressing down the cord 7 with a strong force. Therefore, although the cord 7 has a certain amount of slack inside the mirror body 4, the cord 7 is held in a relatively tensioned state without being affected by the slack toward the inside of the vehicle body from the hook 8.

《Effects of the invention》 Since the present invention has the above-mentioned configuration,
The cord that electrically connects the drive unit 3 and the mirror tilting switch (not shown) inside the vehicle body is made strong by the hook 8 that is press-fitted into the hook mounting boss on the vehicle body mounting surface of the mounting base. Because it is held down by force, the slack created between the drive unit and the mounting base will not be fully extended, and when installing it on the vehicle body, the cord may be caught between the mounting base and the vehicle body mounting part. Moreover, even if the mirror body receives an impact and falls over, the cord will not be torn. Furthermore, if the cord is always protected by a protective wall inside the vehicle body mounting surface, when the mirror body is folded down, the cord will not come into contact with the inner periphery of the vehicle body mounting hole and cause electrical problems. .

Furthermore, since the cord is easily held by press-fitting the hook into a hook attachment boss formed on the vehicle body attachment surface, the number of parts is small and the number of assembly steps can be reduced.
