Claims

[Scope of utility model registration request]

In a shift fork that moves a sleeve in the axial direction of the transmission rotation shaft in order to couple and detach from the transmission rotation shaft a transmission gear supported by a bearing so as to be able to idle on the transmission rotation shaft, the engagement portion of the shift fork The sleeve is configured to guide lubricating oil, which passes through the transmission rotating shaft and is supplied to the bearing of the transmission gear supported by the transmission rotating shaft, into an annular groove on the outside of the sleeve in which the sleeve is slidably engaged. A lubricating device for a shift fork, characterized in that a lubricating oil guide path is provided that communicates between an outer annular groove and an inner side of the sleeve.
