Manual transmission

Abstract

A manual transmission includes a shift and select shaft supported by a housing and reciprocatable in an axis line direction and a rotational direction, an outer lever fixed to a first end of the shift and select shaft at a base portion thereof, an outer lever pin fixed to an end portion of the outer lever, a connecting member rotatably attached to the outer lever pin, a shift cable an end of which is connected to the connecting member via a guide member secured to the housing, a bearing member having a lower degree of frictional coefficient, and the connecting member being connected to the outer lever pin through the bearing member so as to be movable in the axis line direction corresponding to an amount of a travel distance of the shift and select shaft in the axis line direction.

Description

Claims

1. A manual transmission, comprising: a shift and select shaft supported by a housing, and reciprocatable in an axis line direction and a rotational direction;an outer lever fixed to a first end of the shift and select shaft at a base portion thereof;an outer lever pin fixed to an end portion of the outer lever and extending in parallel with the shift and select shaft;a connecting member rotatably attached to the outer lever pin;a shift cable an end of which is connected to the connecting member via a guide member secured to the housing;the shift and select shaft being reciprocated in the axis line direction in response to a manual operation for selecting a fork shaft out of plural fork shafts and reciprocated in the rotational direction in response to a manual operation for reciprocating the selected fork shaft, so that a shift gear from among plural shift gears is selected;a bearing member having a lower degree of frictional coefficient; andthe connecting member being connected to the outer lever pin through the bearing member so as to be movable in the axis line direction corresponding to an amount of a travel distance of the shift and select shaft in the axis line direction.

2. The manual transmission according to claim 1, wherein the shift and select shaft is reciprocated in the axis line direction in response to a manual operation of a select lever and the shift and select shaft is reciprocated in the rotational direction in response to a manual operation of the shift cable.

3. The manual transmission according to claim 1, wherein the bearing member includes a ball bearing which allows an axial movement and a rotational movement of the connecting member.
