摘要：A synchromesh device for a transmission includes: a shaft; a sleeve; an idler gear;a gear piece; a synchronizer ring; a first spline, a second spline and a third spline, the firstspline of the sleeve being engageable with each of the second spline of the gear pieceand the third spline of the synchronizer ring; and a first chamfer, a second chamfer and a
third chamfer, formed at one end of the first spline, one end of the second spline andone end of the third spline, respectively, for a spline-engagement and for a thrust-through operation. The first chamfer of the sleeve includes a small-diameter sidethrusting through the third chamfer at the time of shifting and a large-diameter sidethrusting through the second chamfer at the time of shifting. A chamfer angle of thelarge-diameter side is smaller than a chamfer angle of the small-diameter side.
