By strengthening the spring, the WPC clutch center spring encourages the pulley to shift gears in the torque band, and quickly and forcibly returns the pulley, which was previously in a high-ratio state, to a low-ratio state when suddenly accelerating from deceleration or on a slope, resulting in sharp shifting characteristics.
By performing a composite treatment including WPC on the surface, it exhibits stable performance even when used for long periods of time at high temperatures.
