A ball engages with a reaction force receiving part provided opposite to the side surface, and by pressing this ball in the engagement direction from the other side of the flange part, a restraining force corresponding to the reaction oil pressure is applied, and the ball is moved between the output shafts. an annular reaction force piston that is slidably supported on the outer periphery of the one shaft, and the inner end portion of the guide hole is connected to the outer periphery of the one shaft that supports the reaction piston on a flange portion; In addition to being shifted so that it is located closer to the axis than the
An escape groove is cut out in a portion of the outer peripheral portion of one shaft that supports the reaction piston, close to the other side of the flange portion and communicating with the guide hole, to allow the ball to enter and exit the guide hole.
