DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift select lever structure for an automatic transmission installed on an instrument panel, particularly an instrument panel select lever device. The shift select lever structure of the present invention can be applied, for example, as a shift select lever of a column shift type automatic transmission.

[0002]

2. Description of the Related Art In vehicles such as automobiles, floor shift type shift levers which are quick and responsive have been employed for many years due to the short distance from the transmission due to the spread of sports type vehicles and the like. In taxis and the like where a large number of occupants are required to be boarded, a manual type so-called column shift lever in which a shift lever is attached to a handle shaft is still used because a front seat also employs a bench seat. . However, as in recent years, automatic transmissions have become the mainstream, and quick automatic transmission control by electronic control has become possible. At present, it is no longer necessary to install a transmission lever on a floor close to the transmission. With these trends, in order to facilitate walk-through in the passenger compartment with the spread of leisure vehicles in recent years, the shift lever installed on the floor often becomes an obstacle when not in use, that is, when the vehicle is stopped. did.

SUMMARY OF THE INVENTION
Attempts have been made to install a select lever device in an automatic transmission on an instrument panel. This type of instrument panel select lever device is different from the conventional column shift device described above in that a speed change rod attached to a handle shaft directly operates a speed change device installed in an engine room. Since the select lever and the automatic transmission only need to be connected with the shift cable only, the installation on the instrument panel was performed by installing the pre-assembled instrument sub-assembly select lever device in the transverse direction of the vehicle body. Since it only needs to be attached to a support beam or the like, the outfitting has been greatly simplified. However, since it is necessary to match the shift position in the automatic transmission and the shift position in the instrument panel select lever device in the outfitting process of attaching the instrument panel select lever device to the actual vehicle, the shaft supporting portion of the select lever in the instrument panel select lever device is required. It was not possible to keep it as a finished product, and there was a risk that bearing parts and the like to be assembled by the outfitting process would fall off and be lost.

[0004] Further, with respect to the harnesses of the shift lock button mounted on the top of the lever knob for operating the select lever, the harnesses of the shift lock button are generally provided inside the select lever in the above-mentioned floor type shift lever. Because of the insertion, the insertion work is troublesome, and the structure is complicated, such as making the select lever hollow.

The present invention solves the above-mentioned problems of the conventional shift select lever structure and makes it possible to temporarily assemble bearing parts and the like in the select lever device. It is an object of the present invention to provide a shift select lever structure that eliminates the risk of loss and can also incorporate a shift lock device having a simple structure.
