A continuously variable transmission includes a variator having a belt wound around a pair of pulleys, and a case forming a container chamber for the variator. The pulleys include fixed pulleys and movable pulleys. The belt includes elements stacked to be arranged in an annular form, and rings binding the element stacked. A circumference wall portion of the case is provided with a monitoring hole enabling flank faces of the elements to be monitored.

Continuously variable transmission

A transmission case () includes a case () and a side cover (). A rotation sensor () including a connector terminal part () is attached to the side cover (). A seal member (FIPG) () is interposed between joining surfaces () of the case () and the side cover (). A notch portion () where the seal member () is accumulated is provided to an outer peripheral surface () of the joining surface () which is adjacent to the connector terminal part (). Accordingly, the amount of the seal member () protruding outward from the outer peripheral surface () of the flange portions () is reduced, thus suppressing connection failure of a connector.

Driving force transmission device

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.
