  • Patent number: 10054197
    Abstract: A shifter gear for reducing a thrust load that occurs in a shifter gear for restraining friction between the shifter gear and a shift fork. A gear part and an engaging part with the shift fork are disposed at an outer periphery of a base part. The spline is disposed at an inner periphery of the base part. The shifter gear is mounted relatively slidable to a gear shift shaft in an axis direction via the spline and is mounted to be incapable of relative rotation around an axis. The shift fork engaging the engaging part is configured to perform a slide operation on the shifter gear. One part of the spline is configured with a splined collar in an axis direction. The splined collar is a different body from the base part and is able to relatively rotate to the part around an axis.
