A transmission includes: a case configured to store oil; a gear power transmission mechanism supported by the case and configured to operate in a state where a part of the gear power transmission mechanism is immersed in the oil stored in the case; a chain power transmission mechanism supported by the case; and a transmission mechanism supported by the case. The case includes a rib configured to cover the chain power transmission mechanism at an upper side of the chain power transmission mechanism in a vertical direction. The rib internally includes an oil passage for supplying oil to the transmission mechanism.

Transmission

A continuously variable transmission has an oil pan, an oil strainer located above the oil pan and a control valve unit located above the oil pan. The control valve unit has a shape having a cutting portion formed by a part of the control valve unit being cut out when viewed from an oil pan side. The oil strainer is arranged so as to overlap the cutting portion. With this structure, it is possible to ease a restriction on layout in terms of a height direction in the continuously variable transmission.

Configurations of control valve unit and strainer in power transmitting device

A power transmission device includes: a gear; a case receiving the gear; and a baffle plate positioned between the gear and the case; the baffle plate including a guide portion arranged to guide an oil scooped up by the gear, into between the baffle plate and the case, and the guide portion being disposed above an oil level within the case, the guide portion being adjacent to an axial side surface of the gear, the guide portion being positioned in the baffle plate on an upstream side in a rotation direction of the gear, and the guide portion including a first bent portion which is positioned on a tip end side, and which is bent in a direction from the case toward the gear.

Power transmission device and manufacturing method therefor

A driving force transmission device includes: a gear; a case receiving the gear; a baffle plate positioned between a side surface of the gear and the case, the baffle plate including a downstream side end portion positioned at a most downstream position in a rotation direction of the gear, the case including a rib protruding toward the downstream side end portion, a clearance positioned between a surface of the rib and a surface of the baffle plate, the rib including a linear portion crossing a rotation direction of the gear.
