Abstract:
[PROBLEMS] To prevent a power roller [(4(7)] from being excessively inclined. [MEANS FOR SOLVING PROBLEMS] Stop members (73, 73) fixed to opposite ends of trunnions [(30 (31)] are provided with convex sections (66, 66). Further, the inner surfaces of end plates (48, 48) constituting a swing frame [(21 (22)] are provided with concave sections (67, 67) at positions opposed to the convex sections (66, 66). The convex sections (66, 66) are inserted in the concave sections (67, 67) in such a manner as to allow the trunnions [(30) (31)] to displace in the direction of swing. Further, the lateral surfaces of the convex sections (66, 66) abut against the inner surfaces of the concave sections (67, 67) on the basis of the swing of the trunnions [(30) (31)], thereby preventing the trunnions [(30) (31)] from swinging more than a predetermined degree.
