[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible cable arranging device comprising an outer casing connected to a connecting fitting and an inner wire movably provided in the outer casing.

[0002]

2. Description of the Related Art For example, a speedometer cable for connecting a vehicle speedometer and a transmission or an accelerator wire for connecting an engine and an accelerator pedal,
When one or both units, such as the parking brake wire that connects the parking brake lever and the brake unit, vibrates or moves, it is not possible to connect them linearly with the rod or shaft. There is known a technique for arranging the flexible wire with the flexible wire.

[0003]

However, in the above technique, as shown in FIG.
The connecting portion 4 at the end of the outer casing 2a is fixed to a mounting member such as an engine or a transmission, and the outer casing 2a is forcibly bent by α by vibration or other external force as shown in FIG. 10, for example. Then, the outer casing 2a is buckled at the outlet of the rear end of the connecting portion, which causes rotation or sliding failure of the inner wire, and in the worst case, the inner wire is broken. In addition, Japanese Utility Model Publication No. 6-50247 and Japanese Patent Application Laid-Open No. 7-19208 are disclosed, but both are technologies relating to a clamp member that supports the intermediate portion of the outer cable and do not solve the problems of the present application.

Therefore, an object of the present invention is to provide a flexible wire routing device in which the outer casing does not buckle at the outlet of the rear end of the flexible wire connecting portion.

[0005]

According to the present invention, in a flexible cable arranging device comprising an outer casing connected to a connecting metal member and an inner wire movably provided in the outer casing, the connecting metal member is provided. A base plate is attached integrally with an attachment member to be attached, and the base plate is provided with a first arm fixed integrally with the connecting fitting and a second arm for holding the outer casing at a certain length from the connecting fitting. .

Further, according to the present invention, the centers of the first arm and the second arm for fixing the outer casing are offset on the same plane with respect to the base plate.

Further, according to the present invention, the centers of the first arm and the second arm for fixing the outer casing are offset so as to be on different surfaces with respect to the base plate.

[0008]

The present invention is configured as described above, and the base plate integrally attached to an attachment member such as an engine or a transmission has a first structure.
The first arm and the second arm are integrally provided, and the first arm
A flexible wire connecting fitting is fixed to the arm of the second arm, and the outer casing is held by the second arm at a fixed length from the first arm. Further, since the first arm and the second arm are formed integrally with the base plate, even if vibration or external force in the lateral direction is applied to the outer casing, the first casing and the second arm are laterally attached to the outer casing at the rear end of the connecting fitting. No excessive force is applied and the outer casing does not buckle.

Therefore, the inner wire does not become astringent, and problems such as catching and poor return do not occur.
