Abstract: A planetary gear has a sun gear having external teeth on an outer peripheral side, a plurality of pinion gears engaged with the sun gear, a carrier supporting the plurality of pinion gears, a circular oil catch plate on an end of the carrier, and a rotation member having a ring gear, on an outer peripheral side of the carrier and the oil catch plate. An engaging element engaged with the rotation member is disposed on an outer periphery of the planetary gear. The oil catch plate includes an open close valve which opens a passage at at least a predetermined rotation number. Lubrication oil supplied to the planetary gear is guided to the engaging element through the passage when the open/close valve is opened. This enables adjusting of the lubrication amount in accordance with a variation occurring in a ratio of a lubrication amount to each part.

Abstract: An oil strainer for a vehicle transmission includes a body case, a suction port member, a suction port, and a connection tube. The body case contains a filtering member. The suction port member is separated from the body case. The suction port is provided in the suction port member. The connection tube has flexibility or stretchability and connects the body case to the suction port member. The connection tube has a structure which is bent or which is expanded and contracted to allow the suction port member to move while following a change in an oil surface of oil in a transmission casing of the vehicle transmission so that the suction port is not exposed at the oil surface when a position of the oil surface varies due to lean of a vehicle or acceleration/deceleration applied to the vehicle.

Abstract: A vehicle engine starting device includes a drive starter gear provided on an output shaft of a transmission and a driven starter gear provided on a crankshaft of an engine are meshed, not only is it possible to start the engine by cranking the crankshaft by means of the driving force transmitted from a driven wheel without requiring a starter motor, but it is also possible to prevent the dragging of the transmission since the driving force is not transmitted to the crankshaft via the transmission. Further, since the gear ratio of the drive starter gear and the driven starter gear is set so that the rotational speed of the crankshaft attains a rotational speed that can start the engine when the vehicle speed reaches a predetermined vehicle speed for starting the engine, it is possible to reliably start the engine by cranking the crankshaft at an optimum speed.
