摘要： A sealing device includes an annular reinforcing ring fixed to a housing, an annular elastic member that includes a fixing portion fixed to the reinforcing ring, and a lip that protrudes from the fixed portion and is in slidable contact with an outer peripheral surface of a shaft, and at least one annular spring that presses the lip against the outer peripheral surface of the shaft, the lip being between the at least one spring and the outer peripheral surface of the shaft. The elastic member is made of an electrically conductive elastic material. A contact surface, which is a part of the lip and is in contact with the outer peripheral surface of the shaft, is straight when viewed in a cross section defined by a plane that includes a central axis of the elastic member. A width of the at least one annular spring is greater than its thickness.

摘要： A gasket (1) includes a body portion (10) in an annular shape having a basal surface (11) to contact a bottom surface (113) of a groove(110) and a top surface (12) to contact a second member (200) and extending over an entire circumferential direction of the gasket (1), a first protrusion pair (20) protruding from the body portion (10) respectively toward both side surfaces (111, 112) of the groove (110) and extending over the entire circumferential direction; and a second protrusion pair (30) protruding from the first protrusion pair (20) respectively toward both the side surfaces (111, 112). Respective second protrusions (31, 32) of the second protrusion pair (30) are disposed at a same position in the circumferential direction, and tip ends (31f, 32f) of the respective second protrusions (31, 32) are formed in a planar shape to be along the side surfaces of the groove (110). A first gasket width (W1) of the gasket (1) is smaller than a groove width (W0), and a second gasket width (W2) is larger than the groove width (W0).

摘要： A battery buffering material which prevents a reaction force from increasing suddenly even when the compression ratio is large, and maintains its heat insulating performance is provided. A battery buffering material 100 is a buffering material disposed between adjacent members which constitute a battery, includes a sheet-like structure made of an elastic material, and front surface protruding portions 21 extending on the side of a front surface 11 thereof and the back surface protruding portions 22 extending on the side of a back surface 13 thereof, wherein the front surface protruding portions and the back surface protruding portions have a hollow conical shape or a hollow spherical segment shape, and the front surface protruding portions 21 and the back surface protruding portions 22 collapse when an external force due to expansion of the members is applied to the battery buffering material.
