Abstract
A shift position detection apparatus for a variable speed gear wherein a shift shaft is moved in an axial direction to perform a speed changing operation. A variable speed gear includes a clutch sleeve disposed for movement in an axial direction on a counter shaft with a shift shaft disposed so as to extend in parallel to the counter shaft. A shift fork is coupled and attached to the shift shaft and has an end engaged with the clutch sleeve. The clutch sleeve is moved in the axial direction through the shift fork to select a shift position. A shift position detection apparatus includes F, R and N shift detection portions provided on the shift fork. The F shift detection portion and the R shift detection portion are spaced by approximately 60 degrees in a circumferential direction on substantially the same plane perpendicular to the axis of a cylindrical portion.
