To obtain, for example, a brake gear having a cooling mechanism which enables further reduction of rotational resistance of a brake rotor.SOLUTION: For example, a brake gear includes: a brake stator; a brake rotor which is provided so as to be rotatable around a rotation center; an actuator which slides the brake stator and the brake rotor with the brake stator and the brake rotor moved close to each other in an axial direction of the rotation center to brake the brake rotor; a case which houses the brake stator and the brake rotor and can house a cooling medium; and a cooling mechanism which can switch a state of the gear between a first state where the cooling medium is housed in the case and a second state where an amount of the cooling medium in the case is smaller than that in the first state.SELECTED DRAWING: Figure 1

    【課題】例えば、ブレーキロータの回転抵抗をより低減することが可能な冷却機構を有したブレーキ装置を得る。【解決手段】ブレーキ装置は、例えば、ブレーキステータと、回転中心回りに回転可能に設けられたブレーキロータと、ブレーキステータとブレーキロータとを回転中心の軸方向に近付けて摺動させることによりブレーキロータを制動するアクチュエータと、ブレーキステータとブレーキロータとを収容するとともに、冷却媒体を収容可能なケースと、ケース内に冷却媒体が収容された第一状態と、ケース内の冷却媒体の量が第一状態よりも少ない第二状態と、を切り替え可能な冷却機構と、を備える。【選択図】図1
