Abstract
A transmission shift fork engages with a coupling sleeve of a synchronizer and shifting the coupling sleeve. The transmission shift fork includes a first part, second part, and at least one fin. The first part is arranged to movably mount the transmission shift fork in a shift fork movement direction. The second part includes a coupling sleeve facing surface, an outwardly facing surface, and a pair of shift-direction facing surfaces. The coupling sleeve facing surface includes at least one coupling sleeve engagement part arranged to engage with an engaging groove formed on an external circumferential surface of the coupling sleeve. The outwardly facing surface includes an oil catch disposed in a position with respect to the coupling sleeve engagement part such that the oil catch captures lubricating oil and supplies to the coupling sleeve engagement part. The fin projects from inside an oil receiving recess defined by the oil catch.
