Claims

[Scope of utility model registration request]

A step portion having a smaller diameter on the outer side in the axial direction is formed on the rotating body, and a ring-shaped worm gear that fits into this step portion is formed with an annular engagement cylinder that projects outward in the axial direction. An outer circumferential locking portion and an inner circumferential locking portion that are displaceable in the radial direction are provided on a portion of the outer circumferential portion and the inner circumferential portion, and a washer-like leaf spring that comes into contact with the outer surface of the engagement cylinder is provided. An outer protrusion and an inner protrusion are provided on the outer circumferential part and the inner circumferential part, and the outer protrusion and the inner protrusion are bent in opposite axial directions and can be engaged with the outer circumferential locking part and the inner circumferential locking part, and the tip of the inner protrusion A contact piece is provided that protrudes in the axial direction,
A locking device for a worm gear for driving a meter cable, characterized in that the axial end of the contact piece is pressed axially inward by an inner race of a bearing fitted to the axial end of the rotating body.
