PROBLEM TO BE SOLVED: To provide a sheave opening amount measurement method of a CVT which can accurately measure a sheave opening amount in an operation state of the CVT.SOLUTION: Inclinations of movable sheaves 11b, 21b are calculated on the basis of distances which are detected by a first displacement gauge 30 which opposes external peripheral ends of the movable sheaves 11b, 21b in a peripheral direction, and a second displacement gauge 31 which opposes the external peripheral ends of the movable sheaves 11b, 21b in the peripheral direction. Sheave openings are calculated on the basis of the calculated inclinations of the movable sheaves 11b, 21b, and distances which are detected by a third displacement gauge 32 which opposes a back face 40b of a fixed sheave 11a being a face opposite to belt slide faces 40a of the fixed sheaves 11a, 21a in an axial direction, and a fourth displacement gauge 33 which opposes the external peripheral ends 41c of the movable sheaves 11b, 21b in the axial direction in a position which is displaced to the third displacement gauge 32 by a prescribed distance in the axial direction.SELECTED DRAWING: Figure 3 |
