Abstract
In a transmission for a saddle type vehicle wherein a shift position sensor for detecting the angular position of a shift drum has a sensor shaft disposed coaxially with the shift drum and wherein an engaging pin disposed along a plane orthogonal to the center axis of the sensor shaft and inserted and passed through and fixed to the sensor shaft is engaged with an engagement groove provided at one axial end of the shift drum, to restrain abrasion or torsion from occurring between the engagement groove and the engaging pin even if a radial load is exerted on the shift drum at the time of a shift change and thereby to promise enhanced durability. The longitudinal direction of the engagement groove is set in a direction orthogonal to the direction in which the greatest one of radial loads on the shift drum is exerted.
