    摘要： A pneumatic tire has a pair of bead portions, side wall portions, a tread portion, and a carcass ply rolled up in its end portion so as to pinch a bead filler. An outer surface of the side wall portion is provided with a concavo-convex region formed by arranging a lot of projecting lines extending in a tire circumferential direction in parallel in the tire diametrical direction, and an arranged density of the projecting lines becomes larger toward the outer side in the tire diametrical direction. An outer peripheral end of the concavo-convex region is positioned in the outer side than a position where an interface between a tread rubber and a side rubber is exposed, and an inner peripheral end of the concavo-convex region is positioned in an inner side than a leading end of the bead filler.

    摘要： A pneumatic tire has a first wall surface faces one side of a circumferential groove, and a second wall surface faces another side of that. The first wall surface alternately has a first inclined surface portion and a first concave portion. The second wall surface alternately has a second inclined surface portion and a second concave portion. A first land portion has a first connection portion connected to a second land portion and a first bottom surface portion constitutes the bottom of the circumferential groove. The second land portion has a second connection portion connected to the first land portion and a second bottom surface portion constitutes the bottom of the circumferential groove. The first inclined surface portion and the second inclined surface portion are alternately arranged along a tire circumferential direction overlapping with each other and a see-through region of the circumferential groove is formed between them.

    摘要： An engine having a variable valve mechanism arranged to switch a lift degree of a valve between a low speed state and a high speed state includes a cam carrier defined by a cam bearing portion, a rocker shaft support, and a hydraulic cylinder support. The cam bearing portion is provided on a line passing through the bore center of a cylinder in a plane perpendicular or substantially perpendicular to the camshaft. The low speed rocker arm swings in response to the low speed cam of the camshaft. The high speed rocker arm swings in response to the high speed cam of the camshaft. The low speed rocker arm includes a through hole. A connecting pin is slidably inserted into the through hole and urged toward the hydraulic cylinder support. A hydraulic cylinder is provided in the hydraulic cylinder support.

    摘要： A pneumatic tire has a rib sectionalized by main grooves extending along a tire circumferential direction in a center portion of a tread surface. Depressions are arranged in series in a center portion in a width direction of the rib so as to leave a space in the tire circumferential direction. The depressions extend in the tire circumferential direction and become wider from both end portions in a longitudinal direction toward a center portion.
