Claim Text:
1. A rotation position detection mechanism for a trunnion axis in a hydraulic stepless transmission wherein, by way of a rotation operation of the trunnion axis, the rotation speed and the rotation direction of an output axis can be changed, comprising: an operation lever whose one side end portion is supported by the trunnion axis so as to be incapable of relative rotation and which is configured to be capable of rotating the trunnion axis by rotating around the trunnion axis; a follower lever whose middle portion is supported by the trunnion axis so as to be capable of free relative rotation; and a detection switch which is turned on/off by one side end portion of the follower lever; wherein, for the operation lever, a link for operating the operation lever is connected to a middle portion thereof so that, when the operation lever is rotated to one direction from a predetermined rotation position by the link, one side end portion of the operation lever comes into tactile contact with one side end portion of the follower lever so as to rotate the follower lever in order to switch between on and off for the detection switch, whereas when the operation lever is rotated to another direction from the predetermined rotation position by the link, the one side end portion spaces apart from the one side end portion of the follower lever whereby the follower lever does not turn.
