Latest Patents
Nishikawa's latest patents include a clutch device and a power transmission device. The clutch device features a unique design that includes a clutch center holding output-side rotating plates alternately arranged with input-side rotating plates. A pressure plate, which is movable toward or away from the clutch center, includes pressure-side fitting teeth that hold the output-side rotating plates. In a half-clutch state, portions of the center-side fitting teeth overlap with portions of the pressure-side fitting teeth when viewed in the radial directions of an output shaft. The power transmission device consists of a pressure member, drive-side clutch plates, driven-side clutch plates, a clutch spring, a separate receiving member, and a back-torque limiting cam. A radially-outside restricting portion is designed to restrict the radially-outward movement of the receiving member relative to the pressure member, maintaining clearance between the receiving member and the inner peripheral wall of a clutch member.
