A pressure regulating valve is provided that can inhibit lowering of sealing performance due to force from an outside without adding elements. A pressure regulating valve 1 includes a base member 2 and a valve body member 3. The base member 2 has a first sealing portion 11 which surrounds an opening portion 120 from an outer periphery side and is annular, a second sealing portion 12 with which the valve body member 3 is provided to be contactable and is annular, and a support portion 21 which supports the valve body member 3. The support portion 21 supports a valve body member 2 such that the valve body member 2 is movable so as to be contactable with the second sealing portion 12. The valve body member 3 has a contact portion 31 and a side wall part 32 which extends from the contact portion 31. The contact portion 31 is contactable with the second sealing portion 12. The side wall part 32 is annular so as to cover the second sealing portion 12 from the outer periphery side and has an inclined portion 33. The inclined portion 33 expands to the outer periphery side as progresses downward.

A gasket capable of suppressing reduction in sealing performance due to an eccentricity of an application target is provided. A sealing device 1 includes an elastic body portion 2 formed from an elastic body. The elastic body portion 2 includes a fitting portion 10 that is an annular part, a lip 20 that is an annular part protruding from the fitting portion 10 to an inner periphery side, and an annular first protruding portion 30. The lip 20 protrudes from an inner end portion 10a of the fitting portion 10 while being inclined to an inner side. A length 1 of the lip 20 in the protruding direction is set based on a minimum crush allowance c when a tube is eccentric at maximum with respect to a through hole. The first protruding portion 30 protrudes from the inner end portion 10a of the fitting portion 10 toward the inner side.

A cushioning sheet (40) is attachable to a container body (21) of a transport container (20). The container body (21) includes a facing portion (23a) facing in a first direction and a plurality of recesses (29, 36) recessed from the facing portion (23a). The first direction is orthogonal to a bottom (23) of the container body (21) and outward from the container body (21). The cushioning sheet (40) includes a sheet portion (50) formed from an elastomer. The sheet portion (50) includes a first surface (50a) to face in the first direction and a second surface (50b) to face the facing portion (23a) to at least partially cover the facing portion (23a). The cushioning sheet (40) includes a protrusion set (60) protruding from the second surface (50b) and including a plurality of protrusions (70, 80, 90, 100) integral with the sheet portion (50). The plurality of protrusions (70, 80, 90, 100) are fittable correspondingly into the plurality of recesses (29, 36).
