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.

Transmission

A transmission apparatus includes a casing provided with shafts therein, a rotational member positioned in the casing at an end portion in an axial direction of the shafts, the rotational member being configured to lift up a lubricating oil so as to supply the lubricating oil to a part that is different from the end portion inside the casing, and an oil passage provided along the axis line direction of the shafts, the oil passage configured to receive the lubricating oil lifted up by the rotational member at a first end portion in a longitudinal direction of the oil passage and to supply the lubricating oil through a second end portion in the longitudinal direction of the oil passage to a part inside the casing placed far away from the rotational member, the oil passage being integrally formed with the casing.
