Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting device for fixing a turn signal body in a predetermined position on a jacket tube by means of a tightening band.

As shown in Japanese Utility Model Application Laid-open No. 53-112283 and FIG. 1, the conventional mounting device has a tightening band b that is integrally molded on the back side of the direction indicator body a and corresponds to about half the circumference of the jacket tube j. An insertion protrusion c for the tightening bolt i and a locking part d for the mating metal fitting e are provided at both ends thereof,
The mating fitting e, which is passed through the locking part d and engaged with one end f, is provided with an insertion protrusion g corresponding to the insertion protrusion c and a locking protrusion h that fits into the positioning hole k of the jacket tube j. The installation work is
Tighten the tightening bolt i very loosely and attach one end f to the locking part d.
Fully open the mating fitting e engaged with the jacket tube j, then use the locking protrusion h to find the positioning hole k, and move the insertion protrusion g closer to the insertion protrusion c. However, the bolt i is then tightened to secure the body, and since the mating fitting e is a separate piece, the parts cost is high, and when inserting the body a into the jacket tube j, the mating fitting e is There is the troublesome work of having to widen the insertion protrusion g of e, and there are drawbacks such as the fact that it cannot be fitted automatically into the locking protrusion h and the positioning hole k. The present invention is an improvement over such conventional attachment devices.

An embodiment of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes a jacket tube into which a steering shaft 2 is loosely inserted and whose end slightly protrudes, and has a positioning hole 3 formed at a predetermined position.

Reference numeral 4 designates a direction indicator body, which has a cancell cam component cylinder 7 that is slightly raised by a spring 6 on the upper surface of the body base 5. The steering shaft 2 is loosely inserted into the center of the component cylinder 7, and slightly protrudes from the upper part. The end surface of the butt tube 1 is brought into contact with the lower surface of the body base 5.

An occluded circular tightening band 8 surrounding the jacket tube 1 is integrally molded on the lower surface of the body base 5 molded from a synthetic resin material. The tightening band 8 has an almost circular shape and protrudes downward for a long time, has protrusions 9 and 10 through which the tightening bolt 16 is inserted at both ends, and is in close contact with about half the circumference of the jacket tube 1. A fixed part 11 and a resilient part 13 which is separated from the base 5 and slightly opened outward by a groove 12 provided between the body base 5 and the body base 5 are provided in a part in the circular direction including the insertion projection 10. The positioning hole 3 of the jacket tube 1 is formed to correspond to the inner periphery of the fixed portion 11, and a resilient tongue piece 14 is cut out from the fixed portion 11 and fitted into the positioning hole 3 on the inner periphery of the lower end. A round projection 15 is provided.

In the present invention, a fixed portion 1 of a tightening band 8 is attached to one side of a jacket tube 1 provided with a positioning hole 3.
1 are brought into contact with each other and the direction indicator body 4 is fitted, the protrusion 15 abuts against the end surface of the jacket tube 1 and escapes outward due to the elasticity of the elastic tongue piece 14 (FIG. 4). By abutting the end face against the body base 5 and turning in the rotational direction, the protrusion 15 finds the positioning hole 3 and is fitted by the elasticity of the elastic tongue piece 14. Then, tighten the bolt 16 and tighten the elastic portion 13 to the outer periphery of the jacket tube to secure it (FIG. 5).

The present invention integrally forms an occluded circular fastening band 8 that surrounds the jacket tube 1 through which the steering shaft is inserted on the lower surface of the turn signal body 4. A notched groove 12 formed in a part of the fastening band 8 is used as an elastic part 13 which is released from the body 4 and the jacket tube 1, and unlike the conventional case, the mating metal fitting is made separately and attached to one end of the fixed part 11. It does not attract the mating metal fitting, and since the elastic portion 13 separates from the surroundings of the jacket tube 1 due to its own elasticity, it does not require manual effort when fitting it into the jacket tube 1 like a conventional mating metal fitting. There is no need to widen the jacket tube 1 with a tool, and since a protrusion 15 corresponding to the positioning hole 3 of the jacket tube 1 is formed on the elastic tongue piece 14 provided on the fixed part 11, the tightening band 8 can be fitted and then rotated. The protrusion 15 is inserted into the positioning hole 3 by the elasticity of the elastic tongue piece 14, and then the insertion protrusions 9 and 10 provided corresponding to each end of the fixed part 11 and the elastic part 13 are tightened with tightening bolts. This has the effect that the direction indicator can be easily installed.
