DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a gear shift operating lever for gear shift control of transmission in a transmission device such as a vehicle, and more particularly to fitting of a holding cylinder to a tapered connecting portion of a folding lever. The mating surface is made of synthetic resin to facilitate the fitting and removal of the holding cylinder, and the tapered fitting part of the holding cylinder is positioned inside the holding cylinder to hold the tapered connecting part by the holding cylinder. To increase the rigidity of the.

[Conventional technology]

In this type of foldable speed change lever,
As a conventional one, a holding cylinder having a taper fitting portion in which a bendable connecting portion between an upper lever and a lower lever is formed on a taper shaft continuous with each other, and the connecting portion formed on the taper shaft is fitted The upper lever is slidably fitted, and the tapered fitting portion of the holding cylinder is fitted to the connecting portion formed on the taper shaft of the gear shift operation lever. It is known that the upper lever is firmly held upright (see, for example, Japanese Utility Model Laid-Open No. 58-97623).

[Problems to be solved by the device]

In the conventional foldable gear shift operation lever, the gear shift operation lever including the upper lever and the lower lever and the holding cylinder fitted to the lever are both made of metal. Although the lever connecting part can be rigidly held by the wedge action between the holding tube and the tapered fitting part of the holding tube, the holding tube is lever-connected to release the holding of the lever connecting part by the holding tube when the lever is folded. There is a problem that the detachment is difficult when detaching from the lever portion, and if the taper angle of the taper fitting between the lever connecting portion and the holding barrel is increased to facilitate detachment of the holding barrel from the lever connecting portion, By reducing the taper fitting area and reducing the wedge action, the fitting force, which is the holding force of the lever connecting part by the holding cylinder, becomes small, and the lever connecting part is operated by operating the lever. There is a problem that occurs only.

The present invention solves the above-mentioned problems of the prior art. By forming the inner surface of the holding cylinder with a synthetic resin, the sliding characteristics of the synthetic resin surface with respect to the metal surface allow the taper fitting between the tapered connecting portion and the holding cylinder. Even when the fitting angle is increased by decreasing the taper angle of the holding cylinder, the holding cylinder can be easily detached from the tapered connecting portion by the detaching force with respect to the holding barrel, so that the holding cylinder can be fitted into and removed from the tapered connecting portion. In addition to facilitating the simplification, the holding cylinder has a fitting portion that extends from the tapered connecting portion to the lower lever, so that the holding cylinder can be positioned by arranging the tapered fitting portion from the end portion of the holding cylinder to the inner portion. An object of the present invention is to provide a gear shift operation lever capable of increasing the rigidity of holding the tapered connection portion by the above.

[Means for Solving the Problems]

In order to achieve the above object, in the gear shift operation lever of the present invention, the lower lever is connected to the upper lever having a small diameter so as to be tilted up and down, and the inner surface is composed. A holding cylinder formed of resin and having a fitting portion extending from the tapered connecting portion to the lower lever is slidably fitted to the upper lever.

[Action]

In the gear shift operation lever configured as described above, the connecting portion in which the upper lever having a small diameter is connected to the lower lever so as to be able to move up and down is formed in a tapered shape, and is fitted to the tapered connecting portion. Since the holding cylinder having the fitting portion is slidably fitted to the upper lever, sliding the holding cylinder toward the lower lever in the upright state of the upper lever allows the upper lever and the lower lever to move. The tapered fitting part of the holding cylinder is fitted to the tapered connection part, which is the connecting part of the upper cylinder, by the wedge action of the taper, and the upper lever is held upright by the lower cylinder by the holding cylinder, and the upper lever and the lower lever are integrated. The gear shift operation lever is capable of performing gear shift operation, but the holding cylinder has a fitting portion that extends from the tapered coupling portion that is the coupling portion between the upper lever and the lower lever to the lower lever. Since it is formed, the tapered connecting part is located inward of the holding cylinder where the holding rigidity is high with respect to the end where the holding rigidity is low, so that the rigidity of the holding cylinder for holding the tapered connecting part is high. Can be realized.

Thus, for example, when the driver wants to move from the driver's seat to the passenger's seat, or when the driver has to get off from the driver's seat while straddling the gear shift operation lever, the gear shift operation lever held upright is obstructed. Therefore, the gear shift operation lever can be removed from the obstacle by pulling up the holding cylinder to the upper lever side and releasing the holding of the tapered connecting portion by the holding cylinder and tilting the upper lever sideways. Since the inner surface of the holding cylinder is made of synthetic resin, the sliding characteristic of the synthetic resin surface with respect to the metal surface reduces the taper angle of the tapered fitting between the tapered connecting portion and the holding cylinder to reduce the fitting force. Even when the holding cylinder is increased, the holding cylinder is easily separated from the tapered connecting portion due to the detaching force with respect to the holding cylinder. It is possible to achieve the reduction.

The reinforcing cylinder 12 may be fitted to the outer peripheral surface of the holding cylinder 8 by forming a plurality of engaging holes 15 corresponding to.

[Effect of device]

The present invention is configured as described above, and since the inner surface of the holding cylinder is made of synthetic resin, the sliding property of the synthetic resin surface with respect to the metal surface causes Even when the taper angle of the taper fitting with the holding cylinder is reduced to increase the fitting force, the holding cylinder is easily separated from the tapered connecting portion due to the detaching force with respect to the holding cylinder, and the holding cylinder is fitted into the tapered connecting portion. Not only is it easy to put on and take off, and the fitting surface of the holding cylinder can be made into a finished surface at the same time as resin molding, so not only is taper processing that requires skill not required, and manufacturing is simple. Since the holding cylinder is formed with a fitting portion extending from the tapered connecting portion which is a connecting portion between the upper lever and the lower lever to the lower lever, the tapered connecting portion is By being positioned to the strong inner portion of the holding rigidity to weak end of lifting stiffness, in which it is possible to achieve the rigidity of the tapered connecting portion held by the holding tube.
