A gasket is configured to be sandwiched between a first sealing surface of a first member and a second sealing surface of a second member, the second sealing surface facing the first sealing surface. The gasket includes an annular elastic body in contact with the first sealing surface and the second sealing surface, the annular elastic body enclosing a space between the first member and the second member. The annular elastic body has a Shore A durometer hardness of 0 or more and 30 or less.

An ultrasound probe includes a piezoelectric body including a first surface; an insulating layer including a covering portion that covers a portion of the first surface and a peripheral edge portion that in plan view does not overlap the piezoelectric body; a first electrode including an electrode portion in contact with the first surface and a terminal portion in contact with a surface of the peripheral edge portion; and a wiring substrate bonded to the terminal portion of the first electrode and to the peripheral edge portion of the insulating layer.

A sealing device seals a gap between an inner peripheral surface of an opening in a first member and an outer surface of a second member that is stationary within the opening. The sealing device includes: a first elastic body that includes: a first outer surface in contact with an inner peripheral surface of the opening in the first member; a first opening; and a first inner surface that defines the first opening; and at least one second elastic body that is located within the first opening of the first elastic body and includes: a second outer surface that faces the first inner surface of the first elastic body with a separation space: and a second inner surface in contact with the outer surface of the second member. The first elastic body further includes a first protrusion that extends inward from the first inner surface and is in contact with the second outer surface of the at least one second elastic body.

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).
