Abstract:
[Problem] To provide a valve and a shock absorber that are inexpensive and provide satisfactory assembling properties. [Solution] A valve (V) according to the present invention comprises: an annular valve body (14); spacers (16, 17) each of which is laminated on the annular valve body (14) and serves as a bending fulcrum for the free end of the annular valve body (14); and valve stoppers (13, 15) each of which faces the spacer (16, 17) side of the annular valve body (14) in the axial direction and regulates the bending of the annular valve body (14) when the annular valve body (14) is bent to abut against the valve stopper (13, 15). The valve stoppers (13, 15) comprise: rings (131, 151) each of which has an axial thickness smaller than that of the spacer (16, 17) and is disposed in the inner periphery or outer periphery of the spacer (16, 17); and laminated annular plates (132, 152) laminated to the spacers (16, 17), respectively.
