Transmission

A transmission comprising:

• a transmission case having a partition wall that defines a transmission chamber;
• a clutch cover that covers the partition wall and forms a clutch chamber adjacent to the transmission chamber with the partition wall interposed therebetween;
• a plurality of rotating bodies accommodated in the transmission chamber;
• a clutch that connects and disconnects a drive source output shaft to and from at least one of the rotating bodies, the clutch being accommodated in the clutch chamber;
• an actuator that is disposed in one of the transmission chamber and the clutch chamber and is driven by a pressure medium to be supplied;
• and
• a pressure circuit block that constitutes at least a part of a pressure circuit for applying pressure to the actuator via the pressure medium and is attached to the partition wall
• wherein the actuator includes a cylinder, and
• wherein the cylinder is constructed by a part of the partition wall.

• wherein the pressure circuit includes a filter that filters the pressure medium,
• wherein the filter is supported by the pressure circuit block, and
• wherein the clutch cover has a maintenance opening formed at a position overlapping with the filter in a side view, and the maintenance opening is openably closed by a lid.
