Abstract: A tire that includes a tread portion having a designated mounting direction to a vehicle can comprise: an outer shoulder land portion having a greatest width, in the tire axial direction, of a ground contact surface among five land portions. The outer shoulder land portion can include a plurality of outer shoulder sipes connected to an outer shoulder circumferential groove. An outer middle land portion can include a plurality of outer middle sipes extending completely across the outer middle land portion in the tire axial direction. The outer shoulder sipes and the outer middle sipes each can include a pair of sipe walls. The outer shoulder sipes and the outer middle sipes can each include a body portion in which the pair of sipe walls are disposed substantially parallel to each other. A width of a body portion of each outer shoulder sipe can be greater than a width of a body portion of each outer middle sipe.

Abstract: Provided is a tire including a tread portion. The tread portion can include three circumferential grooves and four land portions. The circumferential grooves can include two shoulder circumferential grooves and one crown circumferential groove. The land portions can include two shoulder land portions and two middle land portions. The two middle land portions can each include a circumferential sipe, a plurality of first middle lateral grooves, and a plurality of second middle lateral grooves. The two shoulder land portions can each include a plurality of shoulder lateral grooves extending from a tread end and terminating in the shoulder land portion.

Abstract: A tire includes a tread portion including first and second tread edges, circumferential grooves, and land portions. The land portions include a crown land portion, a first middle land portion, and a second middle land portion. Under a 50% loaded condition, the first middle land portion, the crown land portion, and the second middle land portion respectively have axial widths W1m, Wc, and W2m of ground contact surfaces, the widths satisfying the following formula, W1m>Wc>W2m. The crown land portion includes an outer ground contact surface and an inner ground contact surface. The outer ground contact surface and the inner ground contact surface respectively have widths Wco and Wci in the tire axial direction, the widths satisfying the following formula, Wco>Wci.

Abstract: A tire includes a tread portion including at least one land portion having axially spaced first and second ends. The at least one land portion is provided with lateral grooves extending from the first end to terminal ends terminating within the at least one land portion, first sipes each extending along a tire circumferential direction to connect a pair of lateral grooves arranged adjacently in the tire circumferential direction, second sipes extending from the first end toward the first sipes, and third sipes extending from the second end toward the first sipes. The second sipes and the third sipes are arranged without intersecting the lateral grooves.

Abstract: A pneumatic radial tire 1 for a passenger car comprises a carcass 6 having a radial structure, a belt layer 7, and a tread portion 2. The tread portion 2 has an outer tread edge (To) and an inner tread edge (Ti). A tread pattern is formed in an asymmetric shape with respect to a tire equator (C). The tread portion 2 is divided into a plurality of circumferential land regions by a plurality of main grooves 10. The circumferential land regions include an outer shoulder land region 16, an inner shoulder land region 17, and a middle land region 18 arranged therebetween. The outer shoulder land region 16 is larger than the inner shoulder land region 17 with respect to rigidity in a tire circumferential direction and the rigidity in a tire axial direction.

Abstract: A power supply device comprises a battery assembly formed by stacking secondary battery cells having safety valves for exhausting gas, end plates being arranged at both end faces of the battery assembly in the stacking direction, a gas duct guiding gas emitted from the safety valves in a prescribed gas exhaust passage, and fixing portions fixing both ends of the gas duct to the end plates in a position where the gas duct faces the safety valves. In a state in which the gas duct is fixed to the end plates in at least one of the fixing portion a fixing opening of a slit is formed extending in the direction parallel to the direction in which the secondary battery cells are stacked, and a fixing member is inserted into the slit fixing opening.

Abstract: A power supply includes batteries, separators, a base plate, and an elastic seal. The batteries have a rectangular-box exterior shape. The separators are interposed between the batteries. The batteries are arranged side by side. The base plate has one surface onto which a battery block of the batteries is fastened. The seal is interposed between a bottom surface of the battery block and an upper surface of the base plate, thereby airtightly closing gaps between them. The separator has recessed parts that form gas-flowing paths between the batteries so that cooling gas can flow along surfaces of the batteries when the separator is interposed between the batteries. The separator includes a plate-shaped bottom cover that is arranged on a bottom surface side of the separator, and protrudes in the side-by-side arrangement direction of the batteries. The bottom cover has a recessed part that is arranged on the seal.
