Abstract

A brake device of a transmission according to the present invention includes: a rotary-side holding member including an inner peripheral surface having a cylindrical surface shape about an axis extending in a forward/rearward direction and configured to hold a rotary-side friction plate on the inner peripheral surface; a fixed-side holding member including an outer peripheral surface having a cylindrical surface shape about the axis extending in the forward/rearward direction and configured to hold a fixed-side friction plate on the outer peripheral surface; and a lubricating oil supply portion supplying lubricating oil to the fixed-side friction plate and the rotary-side friction plate. The fixed-side holding member is provided in a transmission casing so as not to rotate. The rotary-side holding member is provided in the transmission casing at a radially outer side of the fixed-side holding member and is rotatable about a central axis of the inner peripheral surface.
