Claims

[Scope of utility model registration request]

- The shaft is rotatably supported in the first direction and the second direction, and notches 7 are formed at multiple locations around the rotation to prevent rotation, and the rotational trajectory of the notches is in the axial direction. A wheel having a smooth rotating circumferential surface at a shifted position, a bias lever supported rotatably in a fixed position and whose rotating end side is elastically biased toward the rotating circumferential surface of the wheel, and this bias lever. The rotating tip of the lever is rotatably supported by a shaft, and the periphery of the shaft support has a contact portion that comes into contact with the rotating circumferential surface of the wheel, and the rotating tip is in contact with the notch of the wheel. When the wheel rotates in a first direction, the wheel is in the wedged state due to the friction between the contact portion and the rotating circumferential surface, and when the wheel rotates in a second direction, the wheel is in the wedged state. A ratchet device for a magnetic recording/reproducing device, comprising a ratchet that is in a detached state.・
