Abstract

The invention relates to a speed ratio change operation device and a speed changer. A speed ratio change operation device includes: a case (101); a shift select lever (103) housed in the case (101) and provided slidably in a direction of an axis and rotatably in a circumferential direction; a speed ratio change operating lever (250) that operates the shift select lever (103); a select-purpose cam (160) that is fixed to the shift select lever (103) and rotates about the shift select lever (103); a lock ball (150) that presses the select-purpose cam (160); and a bevel portion (163, 164) that is formed in an end portion of a press surface (162, 163, 164) of the select-purpose cam (160) which is pressed by the lock ball (150), the end portion being positioned in a shift displacement direction in which the shift select lever (103) is displaced at the time of a shift operation. The bevel portion is inclined so that a point on the bevel portion approaches the shift select lever (103) as the point is moved in the shift displacement direction. Thus, the operation feeling of the shift operation can be improved.

Description

technical field [0001] The invention relates to a speed change operating device and a transmission. More particularly, the present invention relates to a shift operating device for a manual transmission, and a manual transmission including the shift operating device. Background technique [0002] Various manual transmissions have been disclosed. For example, Japanese Patent Laid-Open No. 11-294582 (JP-A-11-294582) discloses a shift operating device that suppresses the gap between the shift fork and the fork shaft when the selection operation is performed by using the operating lever. of twisting and twisting occurs. The shift operating device includes a fork shaft, a housing shift lever fitted and fixed to the fork shaft, a groove portion formed on an end surface of the housing shift lever, and a pin for suppressing the movement of the fork shaft in a selection direction. [0003] In addition, the shift operating mechanism of the manual transmission disclosed in Japanese ...
