Abstract

A detent mechanism associated with a selector mechanism for change-speed gears in a manual transmission which includes a shift-and-select shaft axially slidably and rotatably assembled within a transmission housing and being linked with a manual shift lever to be axially moved in selecting operation of the shift lever and to be rotated in shifting operation of the shift lever. The detent mechanism comprises a casing rotatable on the shaft but axially fixed to the same, the casing being formed at its inner wall with a plurality of equiangularly spaced axial detent grooves in parallel with the axis of the shaft, a spring loaded follower element radially movable within a portion of the shaft and being selectively retained in the axial detent grooves of the casing under resilient load, and a guide pin secured to the transmission housing and being slidably engaged with an axial slot of the casing.
