In the clutch hydraulic circuit, which introduces the accumulated pressure of the accumulator into the clutch cylinder prior to the supply pressure from the hydraulic pump when the switching valve is turned on, a relief valve is provided in the middle of the accumulator circuit that opens toward the accumulator side. A hydraulic circuit for a clutch in which a valve and a check valve that opens from the accumulator to the main flow path are installed in parallel.
