Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever groove seal structure for a cover member, and more particularly to a seal structure for sealing a lever groove of a column shift lever of a steering column cover of an automatic vehicle so that the lever can be operated. .

[0002]

2. Description of the Related Art Conventionally, for example, a column shift lever (operation lever) of an automatic vehicle has a cover member covering the operating side of the operation lever, and the operation lever is projected from a lever groove of the cover member. The lever groove has a linear shape or a bent shape, and the inside of the groove is sealed by a rubber sheet having a cut corresponding to the groove shape so that the operation lever can be operated.

[0003]

However, if the sealing material of the rubber sheet that seals the lever groove is thin, it has no durability and is torn, and if it is thick, the resistance of the lever operation is large and the operability is poor. Further, when the arrangement of the sealing material is a curved surface, the rubber sheet is likely to be wrinkled or deformed, which causes a problem in the sealing property. In particular, when the lever groove of the automatic column shift lever has a bent shape, the deformation of the sealing material has a disadvantage that the resistance when operating the lever increases.

Therefore, an object of the present invention is to eliminate the above-mentioned inconveniences in the conventional rubber groove lever groove seal material, and the sealability is improved regardless of the thickness of the seal material or the shape of the lever groove. It is an object of the present invention to provide a lever groove seal structure for a cover member, which has good operability of the operating lever for a long period of time.
