Abstract

A transmission includes: a casing of the transmission; a shaft rotatably supported by the casing and having an oil passage; plural gears mounted on the shaft. The lubricant is partly lifted and stirred in response to a shift operation implemented by selectively engaging and rotating the gears. The transmission further includes a lubricating mechanism placed at a position higher than the shaft and having an upper end opening in an upward direction so as to collect and store the lifted lubricant. The lubricating mechanism is provided with an oil supply port through which the lubricant is guided to the oil passage of the shaft.
