Abstract: A valve includes: a valve case; and an annular valve body, one of the inner circumference end and the outer circumference end of the valve body being formed as the free end capable of moving towards both sides in the axial direction with respect to the valve case. The valve case has the annular opposing surface capable of opposing to the free end so as to form the gap therebetween, and the guide surface that is positioned on one side of the opposing surface in the axial direction, the guide surface being continuous with the part of the opposing surface in the circumferential direction. The guide surface is inclined in the direction away from the valve body as the distance from the opposing surface is increased.

Abstract: The valve includes a valve case; an annular valve body, an outer peripheral end of which is a free end movable to both sides in an axial direction with respect to the valve case; a facing portion provided in the valve case, the facing portion including an annular facing surface which is located on an outer peripheral side of the valve body and is configured to face the free end with a gap; and first and second valve stoppers which are located on both sides respectively in the axial direction of the valve body. The first and second valve stoppers, respectively, have a plurality of support portions that are configured to support different positions of the valve body in a radial direction at different heights when the valve body deflects.

Abstract: A valve structure of a shock absorber includes a piston to which a first communication passage and a second communication passage are provided, and a load application member that applies an initial load to a first leaf valve. The initial load is applied to the first leaf valve within a range between the inside in the radial direction from a first seat part and the outside in the radial direction from an abutting part of the piston, the first seat part being positioned on the outside in the radial direction of the first communication passage.
