摘要： A non-pneumatic tire includes a support structure for supporting a load from a vehicle. The support structure includes an inner annular portion, an outer annular portion concentrically provided on an outer side of the inner annular portion, and a plurality of connecting portions which connect the inner annular portion and the outer annular portion to each other and are provided in a tire circumferential direction independently of one another, the plurality of connecting portions are configured such that elongated plate-like first connecting portions and elongated plate-like second connecting portions are arrayed along the tire circumferential direction, a plate thickness is smaller than a plate width, a plate thickness direction is oriented to the tire circumferential direction, and a plate thickness at a tire radial direction inner end coupled to the inner annular portion is larger than a plate thickness at a tire radial direction center portion.

摘要： A method for forming a cylindrical rubber member includes bringing a die 11 close to a forming drum 2, forming a winding start portion S1 by extruding a rubber S and simultaneously starting to rotate the forming drum 2 to gradually increase an extruding amount to an amount Q1 and gradually increase a distance between the die 11 and the forming drum 2 to a distance D2 corresponding to a desired thickness of the cylindrical rubber member, winding the rubber S by maintaining the extruding amount at the amount Q1, and maintaining the distance between the die 11 and the forming drum 2 at the distance D2, and forming a winding end portion S2 on the winding start portion S1 by maintaining the distance between the die 11 and the forming drum 2 at the distance D2 and gradually reducing the extruding amount from the amount Q1.

摘要： The sheet-like rubber forming device has a die body which has an opening having a predetermined cross sectional shape, and a variable die lip which is arranged in a front side of the die body and can change the height of the opening. The variable die lip is constructed by a first movable body and a second movable body. The die lip control unit controls the variable die lip so as to drive the first movable body in an opening direction from a state in which the first movable body and the second movable body are closed when the forming is started, hold the positions of the first movable body and the second movable body after reaching a predetermined height, and drive the second movable body in a closing direction when the forming is finished.
