DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift operation device for a vehicle, and more particularly, to a shock absorbing structure for a device having a device main body and a shift lever projecting from the device main body.

[0002]

2. Description of the Related Art Conventionally, as an impact-absorbing structure of this type, a device main body is swingably provided on a body frame and the swing is restrained by a restraining member. There is a known configuration in which the restraint of the restraint member is released to swing the speed change operation device (see Japanese Patent Application Laid-Open No. H10-16597).

[0003]

However, if it is constructed in a swinging / constraining manner as in the prior art, there is a problem that the structure becomes complicated and the cost is high.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an impact force absorbing structure having a simple structure and a low cost.

[0005] To achieve the above object, according to the present invention,
What is claimed is: 1. A shock absorbing structure for a vehicle shift operating device comprising an apparatus main body and a shift lever protruding from the apparatus main body, wherein the apparatus main body is fixed to a vehicle body via an impact force absorber, and the impact force absorbing structure is provided. The body is broken by the impact force acting on the device, and an impact force absorbing structure of the vehicular shift operating device that allows the device to move in the direction of the impact force is provided.

When the apparatus main body is formed as a fixed type as described above, the structure can be simplified and the cost can be reduced as compared with the conventional swinging / restricting type.
