摘要： [Problem to be Solved]To provide an antivibration device that can realize low dynamic spring characteristics in a high vibration region while securing a damping force in a low vibration region.[Solution]In the case where a load input in the axial direction of a coupling member is a predetermined value or smaller, the dynamic spring constant of a first bush 10 is set larger than that of a second bush 20, and the loss factor of the second bush 20 is set larger than that of the first bush 10. On the other hand, in the case where the load input in the axial direction of the coupling member 30 exceeds the predetermined value, the dynamic spring constant of the first bush 10 is set smaller than that of the second bush 20.

摘要： A modified diene polymer is obtained by decomposing a diene polymer having a carbon-carbon double bond in a main chain by oxidative cleavage of the carbon-carbon double bond to reduce a molecular weight, changing acido-basic properties of a system containing polymer fragments obtained such that the system is changed into a basic system when the system is acidic and the system is changed into an acidic system when the system is basic to combine the polymer fragments, thereby obtaining an intermediate polymer having an altered structure, and epoxidizing a carbon-carbon double bond moiety of a main chain of the intermediate polymer.

摘要： The object of the present invention is to provide a method and an apparatus for molding an annular member capable of accurately molding an annular member into a predetermined cross-sectional shape even if the annular member has a thick-walled inner peripheral part and a thin-walled outer peripheral part. The method for molding a bead filler (11) including a thick-walled inner peripheral part (11a) and a thin-walled outer peripheral part (11b), the method comprising the steps of extruding, into an annular shape, rubber (R1) by a first extruder (30) onto a molding table (20) through a first die (31) provided with an opening having the same cross-sectional shape as that of the inner peripheral part (11a) while the molding table (20) is rotated, and molding the inner peripheral part (11a); and extruding, into an annular shape, rubber by a second extruder (40) onto the molding table (20) through a second die (41) provided with an opening having the same cross-sectional shape as that of the outer peripheral part (11b) while the molding table (20) is rotated, and molding the outer peripheral part (11b).

摘要： Edge separation in a turned-up end portion (5E) of a carcass ply (5) is suppressed. In a pneumatic tire comprising a bead core (4) embedded in a bead portion (3) and a carcass ply (5) turned up and locked around the bead core (4), a rubber sheet (10) is prepared using a wet masterbatch containing natural rubber and/or polyisoprene rubber and carbon black, and the rubber sheet (10) is arranged on at least one of front and back sides of the turned-up end portion (5E) of the carcass ply (5).

摘要： A pneumatic tire includes a rib formed in a center region of a tread portion and extending continuously in a tire circumferential direction. The rib has a plurality of respective recessed portions disposed along the tire circumferential direction at a center portion thereof. A bottom surface of each of the plurality of recessed portions is formed of a pair of inclined surfaces respectively deepened toward both sides. A groove portion extending in a tire width direction toward a kicking-out side in the tire circumferential direction is configured to communicate with one side of the recessed portion.
