BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide supporting member for guiding and supporting a cable, and more particularly to a guide supporting member having a vibration damping body incorporated therein so as not to transmit vibration to the cable.

In this specification, a cable assembly transformer control for guiding and supporting a cable extending from a shift lever of an automobile to a mission on a mission side as a guide supporting member will be described, but the present invention is not limited to this. Absent.

[0003]

2. Description of the Related Art Conventionally, a guide supporting member for guiding and supporting a cable extending from a shift lever of an automobile to a mission is known from Japanese Patent Publication No. 63-27169.

The guide supporting member 10 described in the above publication is shown in FIG.
As shown in FIG. 3, a cylindrical conduit 11 that covers the cable 1 so as to be movable in the axial direction, a substantially cylindrical vibration damping body 13 that covers the circumference of the conduit 11, and a substantially cylindrical shape that covers the circumference of the vibration damping body 13. The housing 14 is formed of a synthetic resin product together with the conduit 11 in order to reduce the weight. Further, the vibration damping body 13 is
It is made of a polymer elastic material that is softer than the conduit 11 and the housing 14 so that the vibration from the stop plate 4 on the mission side for fixing the housing 14 is not transmitted to the cable 1.

A stopper 12 fitted in a recess 13a of the vibration damping body 13 is fixed to the outer periphery of the conduit 11 in order to prevent the vibration damping body 13 from coming off.

Flange portions 14a and 14b protruding toward the inner peripheral surface of the housing 14 are in contact with the front and rear ends of the vibration damping body 13 to prevent the vibration damping body 13 from coming off.

On the outer periphery of the front end of the housing 14, a plurality of flexures extending in opposition to the step portion 14c abutting the peripheral edge of the mounting hole 4a of the stop plate 4 and the step portion 14c for fixing the housing 14 to the stop plate 4 are provided. Locking claw 14d is formed. Further, on the inner peripheral surface of the flange portion 14b of the housing 14, the spherical portion 16a on the base side of the guide pipe 16 is provided.
A cup spacer 15 is fixed so that it can swivel.

The guide pipe 16 supports the slider rod 2 connected to the tip of the cable 1 so as to be axially movable and rotatable. This slider rod 2
Will be connected to an operation lever (not shown) of the mission. Incidentally, 17 is a cap of the guide pipe 16.

The conventional guide support member 10 is constructed as described above, and the housing 14 has the stop plate 4 on the mission side.
When the cable 1 is moved, the slider rod 2 moves along with the turning motion, thereby operating an operation lever (not shown) on the mission side.

In the conventional guide support member 10, since the vibration damping body 13 is interposed between the housing 14 fixed to the stop plate 4 and the cable 1, the transmission side stop for fixing the housing 14 is fixed. It is possible to prevent the vibration from the plate 4 from being transmitted to the cable 1 or, conversely, the vibration on the cable 1 side to be transmitted to the housing 14 side.

[0011]

However, in the conventional guide supporting member 10, the stopper 12, the vibration damping body 13, and the housing 14 fixed to the outer periphery of the conduit 11 are sequentially formed by injection molding. .

Therefore, the production efficiency is low, the number of manufacturing steps is increased, and the manufacturing cost is increased in terms of the yield due to defective products. Further, the conduit 11 itself is a long product, and the handling of the conduit 11 is poor at each molding,
This resulted in a decrease in work efficiency and an increase in work space, further increasing the manufacturing man-hours and manufacturing costs.

The present invention solves the above-mentioned problems, and an object of the present invention is to provide a cable guide supporting member which can be easily manufactured and which can reduce the number of manufacturing steps and the manufacturing cost.
