The invention provides a brake device for a railway vehicle. A railway vehicle brake device (1) is provided with: an electric motor (2); a speed reducer (20) having an output rotating body (21) for outputting the rotational force input from the motor; a conversion mechanism (30) that has an input rotating body (31) to which the rotational force output from the output rotating body is input, and a linear motion member (32) that converts the rotational motion of the input rotating body into linear motion in movement directions (VA, VB) parallel to the rotational axis of the input rotating body; and friction pieces (40A, 40B) to which the linear motion of the linear motion member is transmitted to brake the railway vehicle. The input rotating body is provided so as to be movable relative to the output rotating body in the movement direction and so as to be able to transmit the rotational motion of the output rotating body to the linear motion member.

    本发明提供一种铁道车辆用制动装置。铁道车辆用制动装置(1)具备:电动机(2);减速器(20),其具有输出从电动机输入来的旋转力的输出旋转体(21);转换机构(30),其具有输入旋转体(31)和直动构件(32),该输入旋转体被输入从输出旋转体所输出的旋转力,该直动构件将输入旋转体的旋转运动转换成与输入旋转体的旋转轴线平行的移动方向(VA、VB)的直线运动;以及摩擦件(40A、40B),直动构件的直线运动向摩擦件传递,而使铁道车辆制动。输入旋转体以可在移动方向上相对于输出旋转体相对移动、且可向直动构件传递输出旋转体的旋转运动的方式设置。
