Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support mechanism for an outside mirror of an automobile.

[0002]

[Prior art]

 Conventionally, the U-shaped support member that supports the outside mirror of a large truck or bus uses a relatively thin pipe with the same diameter, and the upper and lower ends of this support member are on the vehicle body side. It was rotatably supported by a member fixed to. Then, in this pipe, electric wires for adjusting the reflection angle of the mirror and motors for the mirror wiper and for the heat wire built in the mirror, and wires connected to switches and power supplies in the cab were passed.

[0003]

[Problems to be solved by the device]

 On the other hand, if the pipe cannot be built in because it is thin, it is exposed to the outside of the pipe and is not well-formed, and there is not enough space around the wiring, and there is a hole at the end of the support member. , The wiring was taken out from this hole and pulled in to the car body side, so the appearance was compounded. In addition, the connection rotation point between the support member and the fixing member for mounting the support member on the vehicle body side may rotate the support member itself for adjusting the reflection angle of the mirror, so that it may not be used for a long time. In the meantime, since it repeatedly rotates, the covering material of the wiring at this location is damaged, and there is also an obstacle that causes the conductor wire to be exposed and a short circuit may occur.Therefore, drainage due to damage to the water pipe for mirror cleaning should be avoided. There was also a problem that it would occur. In addition, since the connection rotation point is exposed, there were drawbacks such as the occurrence of rust and the accompanying reduction in rigidity, and lack of smooth rotation.

According to the present invention, a support tube and a fixed tube for attaching the support tube to the vehicle body side are gradually increased in diameter from the outside mirror installation portion to the vehicle body side, and various types of wiring are provided. The purpose of this is to enable the storage of pipes and pipes, to prevent the coating of wiring and damage to pipes, and to prevent the occurrence of short circuits and drainage.

[Effect of device]

 According to the present invention, the support pipe of the outside mirror, the fixed pipe and the hollow connecting tool for connecting the support pipe to the vehicle body side are gradually increased in diameter as the support pipe approaches the vehicle body side from the upright portion. As a result, the conductors and water supply pipes installed on the outside mirror installed in the upright part can be pulled out into the vehicle body by inserting them inside the support pipes, fixed pipes, and hollow connectors, and thus for wiring and piping. The appearance is good in combination with the fact that the number of holes drilled in the support tube is minimal. In addition, since a space is created around the wiring and piping, and a bracket is used in the connecting and rotating part, where holes for passing internal organs such as conductors and water supply pipes are used, it is possible to rotate the support pipe for a long time. Even if you go, you can bend the internal organs gently, there is no damage to the conductor coating or damage to the water supply pipe, so there is little risk of electrical short circuits or water leaks. It can be used after a long period of operation and water supply operation.

[0015] Furthermore, since the cover is covered at the connection rotation point by the bracket, it has a waterproof and rustproof effect on the bracket, and the rigidity is also improved, and the cover is made of a flexible material and has a bellows. Since it is formed in a shape, it is possible to smoothly rotate the connection point.

Further, since the diameter of the root portion of the pipe is larger than that of the conventional one, the cross-section system can be large, and the vibration that has been conventionally generated in the outside mirror during traveling is absorbed by the root portion of the pipe, and Vibration generated in the mirror itself is reduced and it can be used for a long time.
