Patent ID: 7104150

Claim:
A shift position detection apparatus for a variable speed gear, comprising: a clutch member disposed for movement in an axial direction on a power transmission shaft; a shift shaft disposed so as to extend in parallel to said power transmission shaft; a shift fork coupled and attached to said shift shaft and having an end engaged with said clutch member, said shift fork being configured wherein in response to a shift operation, said shift shaft and said shift fork are moved in the axial direction to move said clutch member in the axial direction on said power transmission shaft to select a shift position; a plurality of shift detection portions provided on said shift shaft or said shift fork in a corresponding relationship to a plurality of shift positions; and a plurality of position sensors individually disposed in an opposing relationship to said shift detection portions, wherein the movement of said shift detection portions in the axial direction by the movement of said shift shaft in the axial direction is detected by said position sensors to detect the shift position; and at least two of said plurality of shift detection portions are disposed at different positions in a same lateral position in the axial direction and are spaced radially relative to each other.
