Abstract: Groove widths of center main grooves are larger than groove widths of inner and outer main grooves. Plurality of lateral grooves are formed at intervals in a tire circumferential direction so as to define inner shoulder blocks belonging to an inner shoulder row. A first raised portion connecting a pair of inner shoulder blocks to each other is formed in the lateral grooves every one other on an inner main groove side. A depth of the lateral groove in the first raised portion is smaller than the depth of the lateral groove in other portions. A second raised portion is formed on the outer main groove in a region defined by an imaginary line connecting an outer intermediate block and an outer shoulder block. A depth of the outer main groove in the second raised portion is smaller than that of the outer main groove in other portions.

Abstract: A sipe is defined by a wall surface including a first side surface and a second side surface and that face each other with a gap therebetween. The first and second side surfaces each include a first portion on the surface side of the land section, a second portion on the bottom side of the sipe, and a third portion interposed between the first portion and the second portion. The first portion of the first side surface and the first portion of the second side surface have complementary shapes. The first portion of the first side surface and the first portion of the second side surface each have a shape having an amplitude in the sipe width direction from one end to the other end in the ripe extending direction, the amplitude gradually decreasing toward the bottom of the sipe from the surface of the land section.

Each of the sipes 30 has, at parts in a sipe longitudinal direction, bottom protrusions 42, 44, 46 protruding from a bottom surface of the sipe 30 toward a tread surface. The concave portion 34 is provided close to the bottom protrusions 42, 44, 46.

Plurality of lateral grooves are formed at intervals in a tire circumferential direction so as to define inner shoulder blocks belonging to an inner shoulder row. A first raised portion connecting a pair of inner shoulder blocks to each other is formed in the lateral grooves every one other on an inner main groove side. A depth of the lateral groove in the first raised portion is smaller than the depth of the lateral groove in other portions. A second raised portion is formed on the outer main groove in a region defined by an imaginary line connecting an outer intermediate block and an outer shoulder block. A depth of the outer main groove in the second raised portion is smaller than that of the outer main groove in other portions.

Abstract: A pneumatic tire includes a tread portion, a sidewall portion, a buttress portion provided between the tread portion and the sidewall portion, multiple first protrusions provided to the buttress portion and spaced in a tire circumferential direction, and multiple second protrusions provided to the buttress portion in spaces between the first protrusions situated adjacently in the tire circumferential direction. The first protrusions have a larger area of top surfaces than the second protrusions and a higher protruding height from the buttress portion than the second protrusions. The second protrusions are provided with recessed grooves that sink below top surfaces.

Abstract: A first block 20 and a second block 30 are aligned in a tire circumferential direction with a groove being interposed therebetween. The first block 20 has a first projected section 22 extending toward the second block 30. The second block 30 has a second projected section 32 extending toward the first block 20. The first projected section 22 and the second projected section 32 overlap each other in a tire width direction. Two-step tapered sections 50, 60 are formed at ends of the first projected section 22 and the second projected section 32. The two-step tapered sections 50, 60 include first tapered surfaces 51, 61 on a ground contact surface side and second tapered surfaces 52, 62 on a groove bottom side. Inclination angles of the first tapered surfaces 51, 61 are larger than inclination angles of the second tapered surfaces 52, 62.

Abstract: The present invention is characterized that a first block 20 in a shape of having a projected section 22 that extends in a tire circumferential direction and a second block 30 in a different shape from the first block 20 are alternately aligned in the tire circumferential direction to forma block row, that two of the block rows are famed, and that the two second blocks 30 are arranged on both sides in a tire width direction of the projected section 22 of the first block 20.

Abstract: A connection terminal is on a flange of a thermal flow meter. A terminal connection part has a first and a second bent part. The first bent part is bent from a first direction to a second direction. The second bent part has is bent from the first bent part to a third direction. The first and second bent parts are formed such that when connection pin parts of a plurality of the connection terminals and terminal connection parts of the plurality of connection terminals are projected onto a first imaginary plane, an imaginary line L extending along a first direction passing through the projection areas of each of the terminal connection parts of the plurality of connection terminals passes between the projection areas of the connection pin parts from among the connection pin parts of the plurality of connection terminals, that are positioned on both sides.
