Belt type continuously variable transmission for vehicle

Abstract

A belt type continuously variable transmission for a vehicle includes: an input shaft and an output shaft disposed in parallel with each other; a pair of groove width variable pulleys disposed on the outer circumferential sides of the input shaft and the output shaft; and a transmission belt wound around each of V-grooves of the pair of the groove width variable pulleys, the belt type continuously variable transmission for a vehicle changing a winding diameter of the transmission belt by changing the groove widths of the V-grooves so as to continuously vary a gear ratio, wherein the groove width variable pulley includes a fixed sheave fixed to an outer circumferential surface of one of the input shaft and the output shaft, and a movable sheave disposed relatively non-rotatably on the one shaft and relatively movably in the direction of the shaft center of the one shaft so as to form the V-groove with the fixed sheave, wherein the belt type continuously variable transmission for a vehicle is disposed with a parking gear having a disc-shaped main body portion fixed to the one shaft on the side opposite to the movable sheave relative to the fixed sheave, and an annular projecting portion projecting from the main body portion toward a wall surface of the fixed sheave on the side opposite to the movable sheave and abutting on the wall surface of the opposite side on the outer circumferential side than the minimum winding diameter of the transmission belt, and wherein the annular projecting portion of the parking gear abuts on the wall surface of the fixed sheave on the side opposite to the movable sheave at a radial position corresponding to the maximum winding diameter of the transmission belt.
