Claims

[Scope of utility model registration request]

(1) A pair consisting of a carrier formed by laminating endless metal bands and a number of metal presser pieces that are movable in the circumferential direction of the carrier via carrier grooves having carrier sliding surfaces. In a drive belt for a continuously variable transmission that is hung on a V-type belt wheel, the carrier sliding surface is provided with angle chamfered portions having a predetermined chamfer angle with respect to the carrier sliding surface at both ends in the carrier movement direction. A presser foot piece characterized in that a connecting lip between the angle chamfered portion and the carrier sliding surface is provided with a curved surface.

(2) The chamfer angle of the angle chamfer of the carrier sliding surface with respect to the carrier sliding surface is 3 to 30 degrees, and the curvature of the curved surface formed at the joint with the angle chamfer six sliding surfaces is ■ Scope of Utility Model Registration Claim 1, characterized in that the carrier is formed with a smaller curvature than the minimum curvature that the carrier can take inside the vehicle.
Presser foot as described in section.
