WIPO Patent Application WO/2017/159146

Kind Code:

A1

Abstract:

Provided is a lubricant guiding structure (1) in an automatic transmission in which a baffle plate (4) for regulating the movement of a lubricant (OL) agitated by a driven sprocket (32) is disposed at one side, where an oil pump (OP) is located, in the direction of a rotational axis (X2) of the driven sprocket (32), the lubricant guiding structure (1) is configured such that: as viewed from the direction of the rotational axis (X2), a partition wall (52) disposed to extend across a chain (33) is provided closer to the chain (33) than a base (40) of the baffle plate (4); as viewed from the direction of the rotational axis (X2), the baffle plate (4) is provided with a guide wall (61) that extends along the torque transmitting-side chain (33A) of the chain (33) wound on the driven sprocket (32); and in the direction of the rotational axis (X2), the guide wall (61) has an inclined portion (611) that is inclined so as to come closer to the chain (33) as the distance to the tip side decreases.
