Transmission and vehicle drive transmission device including the same

A transmission comprising:

• a planetary gear mechanism including an input element drivingly connected to a drive source for a wheel, an output element drivingly connected to the wheel, a first stationary element, and a second stationary element;
• a first fixing device configured to selectively fix the first stationary element to a non-rotary member;
• and
• a second fixing device configured to selectively fix the second stationary element to the non-rotary member, wherein
• the first fixing device includes a first fixed gear connected to the first stationary element so as to rotate integrally with the first stationary element, a first fixing gear that meshes with the first fixed gear, and a first friction engagement device configured to selectively engage the first fixing gear with the non-rotary member,
• the second fixing device includes a second fixed gear connected to the second stationary element so as to rotate integrally with the second stationary element, a second fixing gear that meshes with the second fixed gear, and a second friction engagement device configured to selectively engage the second fixing gear with the non-rotary member,
• the first friction engagement device is disposed coaxially with the first fixing gear,
• the second friction engagement device is disposed coaxially with the second fixing gear,
• a rotation axis of the first fixing gear and a rotation axis of the second fixing gear are parallel to each other, and
• assuming that an axial direction is a direction along the rotation axis of the first fixing gear and the rotation axis of the second fixing gear,
• the first friction engagement device and the second friction engagement device are disposed so as not to overlap each other in an axial view along the axial direction.
