本発明は、手動変速機のフォークロ・ンド支持構造に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a forklift support structure for a manual transmission.
従来の手動変速機の変速操作機構のフォークロッド（シ

されてｌ、Ｎた。One end of the fork rod of the shift operation mechanism of a conventional manual transmission (the rod that moves when the shift lever is operated and operates the coupling sleeve of the synchronizer via the fixed shift fork) is connected to a hole provided in the casing. They are supported by fitting together so that they can be moved axially in the same direction.

う問題点があった。However, in the fork rod support structure of such a manual transmission, the frictional resistance is large and operability is poor, and when a particularly large operating force is applied and the fork rod bends, the friction between the fork rod and the hole increases. There is a problem in that the number increases and the operability deteriorates.

。Another conventional fork rod support structure for a manual transmission is one in which a linear motion pole bearing is provided in a hole in a casing in order to solve the above problem. However, there was a problem in that the price was high because a pole bearing was used.

より、上記問題点を解消することを目的としている。The present invention has been made by focusing on the above-mentioned problems in the conventional fork rod support structure of a manual transmission, and has solved the above-mentioned problems by providing a roller at the end of the fork rod. The purpose is to eliminate it.
以下、本発明をその実施例を示す添付図面の第１及び２
図に基づいて説明する。Hereinafter, the present invention will be described with reference to Figs. 1 and 2 of the attached drawings showing embodiments thereof.
This will be explained based on the diagram.

is supported by Note that the diameter of the roller 8 is somewhat larger than the diameter of the end of the fork rod 6-. The roller 8 is connected to a hole 12a provided in the casing 12 (this hole 12a).
The diameter of the roller a is approximately equal to the diameter of the roller 8). Note that the transfer surface of the roller 8 is directed toward the center point O of the shift fork 4 (that is, the point of application of force).

ことができる。During a speed change operation, the fork rod 6 moves under force in the axial direction, but the fork rod 6 is supported within the hole 12a of the casing 12 via the rotating roller 8, and only an extremely small frictional force is generated. Therefore, the speed change operation can be performed easily. During a gear shift operation, the fork rod 6 receives a bending moment from the shift fork 4 and causes a slight bend, but there is a gap between the fork rod 6 and the hole 12a of the casing 12, and the two do not come into contact. Therefore, even when a large operating force is applied, operability is impaired.As explained above, according to the present invention, the end of the fork rod that transmits the movement of the shift lever to a four-way device such as a synchronizer A roller is rotatably attached to the part, and the fork rod is supported in the hole of the casing so that it can move in the axial direction via this roller, reducing the frictional force of the fork rod at a very low cost and allowing for gear shifting operation. The operability of the mechanism can be improved.
