The disclosed leaf valve structure is provided with a ring-shaped valve sheet and a leaf that sits on the valve sheet under a prescribed elastic support force, resisting pressure from a working fluid on the inside of the valve sheet. A depression is formed in the valve sheet, said depressing having openings to the inner edge of the valve sheet and the seating surface of the leaf, respectively. This creates a region where the pressure of the working fluid on the inside of the valve sheet can more easily act on the surface where the leaf valve sits on the valve sheet. This minimizes the effect that the surface absorption force exerted on the leaf valve by the valve sheet has on the cracking pressure, allowing the leaf valve to be lifted up at a stable cracking pressure.
