摘要

Continuous belt continuously variable transmission (15) includes a primary sheave belt (29), and the secondary sheave (30) and (31). The primary sheave (29), the second sheave body to form a (37) a belt groove is wound belt (31) between the first sheave member and (34a), the first sheave member and (34a) and (34b), the pressing body of multiple varying width belt groove (37) to slide the second sheave body and (34b) in response to centrifugal force and (45), the second sheave body is (34b) Upon reaching the minimum speed ratio position to narrow the most width belt groove (37), a plurality of stoppers for limiting the movement of (45) pressing body by contact with the (47a) outer surface pressing body (45) (66) I contains, and. Stoppers (66) is shaped to accelerate the wear of the outer surface portion of the push body (45) of (47a).
