PROBLEM TO BE SOLVED: To provide a parking brake mechanism which can stably generate a brake force.SOLUTION: A brake main body part 61 is a multi-plate clutch which brakes the rotation of a power transmission shaft 23 by making a plurality of inside friction plates 62 and a plurality of outside friction plates 63 pressure-contact with each other by using a pressing part 64. A brake transmission part 70 comprises: a turning part 71 which coincides with a turning axial core L of the power transmission shaft 23, and turns with the turning axial core L as a center; an equal transmission mechanism 72 which makes a turning force imparted to the turning part 71 equally act on the turning part 71 in a peripheral direction according to an operation of a brake pedal; and a motion conversion mechanism 73 which converts a turn of the turning part 71 around the turning axial core L to the movement of the pressing part 64 in a direction along the turning axial core L.SELECTED DRAWING: Figure 5

    【課題】制動力を安定して発生させることができる駐車ブレーキ機構を提供する。【解決手段】ブレーキ本体部61は、複数の内側摩擦板62及び複数の外側摩擦板63どうしを押圧部64により圧接することにより動力伝達軸23の回転を制動する多板クラッチであり、ブレーキ伝達部70は、動力伝達軸23の回転軸心Lと一致した回動軸心Lを中心として回動する回動部71と、ブレーキペダルの操作に応じて回動部71に付与される回動力を回動部71に対して周方向に均等に作用させる均等伝達機構72と、回動部71の回動軸心Lまわりの回動を、押圧部64の回動軸心Lに沿った方向への移動に変換する運動変換機構73と、を備えている。【選択図】図5
