PROBLEM TO BE SOLVED: To provide a holding mechanism which is satisfactorily disposed in a limited space and suppresses trouble such as an operational defect, and a parking device with the same.SOLUTION: A cam 60 which is fitted to a notched part 52 of a shaft member 40, is formed in a cylindrical shape regarding a right half in the figure, in a shape formed with a protrusion 61 protruding obliquely from the top of the cylindrical shape to a lower left side regarding an upper side of a left half, and in a shape formed with a protrusion 62 resulting from rounding corners of a rectangular shape regarding a lower side of the left half. When oil pressure to a hydraulic piston 32 is reduced in the state where the cam 60 is fitted to the notched part 52, a force acts on the protrusion 61 by an energizing force of a spring 36. A horizontal component of the force is balanced by summing up forces acting on the protrusion 62 and an abutment part 63, and the vertical component thereof is balanced by summing up forces acting on a bottom and the top of the cam 60. Thus, a force which is orthogonal to an axial direction does not act on a moving member 58. |
