Title:
PULLEY WIDTH ADJUSTING DEVICE FOR CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP3692821
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently perform the axial movement of a displacement side pulley piece by a small-sized and lightweight structure.
SOLUTION: An external thread 30 is formed on the outer peripheral surface of a first cylindrical member 20 rotatably supported in relation to a transmission case 18a. The central axis of the first cylindrical member 20 is eccentric in relation to the central axis of a rotary shaft 1b having a pulley. An internal thread 29 is formed on the inner peripheral surface of a second cylindrical member 22 rotatably supported on a displacement side pulley 4b. A part in the circumferential direction of the internal thread 29 and a part in the circumferential direction of the external thread 30 are meshed with each other.
