摘要： A single-band type metallic belt wound between annular V-grooves of a drive pulley and a driven pulley is provided. The metallic belt includes a metal endless band having at least one layer, and a plurality of metal push blocks engaged and superimposed on the band in a manner enabling sliding in a longitudinal direction of the band. The push block includes a body formed by bending a single wire material and subsequently performing pressing so as to have two outer side surfaces defining side contact surfaces that are inclined to respectively make frictional contact with two inner surfaces of the annular V-grooves. A pair of pillars respectively extend along extensions of the two contact surfaces of the body and have an outer surface that is continuous with the side contact surfaces of the body. A pair of opposed hooks extend. The outer side surface of the push block that makes frictional contact with the V-grooves include an oil film breaking portion. An opening is defined by the pair of hooks, and a band holding surface is formed on the body in the opening. The band is inserted in the opening of each push block and held on the band holding surface. A metal retainer is arranged on an outer surface of the band in a manner engageable with the pair of hooks to ensure engagement between the band and the push blocks. A ring is attached to the outer surface of the retainer to prevent deformation of the retainer.

摘要： At least one belt layer in which one or plural rubber-coated belt cords are arranged to be spirally wound almost in parallel with a tire circumferential direction on the outer circumference of a body ply. The belt cord is small in the increase rate of tensile load to stretch rate in the range of a predetermined stretch rate or less, but becomes large in the increase rate of the tensile load in another range exceeding the predetermined stretch rate. Therefore, during a vulcanizing and forming process, the belt cord is expanded together with unvulcanized compounded rubber under a small tensile load, and it does not occur to prevent body ply cords from being expanded, so that a green tire is vulcanized and formed with respective parts thereof being adhered as a result of being expanded to keep a correct shape.

摘要： A cylindrical body ply is mounted around a cylindrical bladder, and annular beads are set on both axial end portions of the body ply. In this state, while the spacing between both axial ends of the body ply is narrowed, an axial intermediate portion of the body ply is increased in diameter by the bladder. Subsequently, bending members formed of rigid bodies are radially moved from the inside to the outside of the body ply to bend both axial end portions of the body ply by the bending members. The bent portions of the body ply wrap around corresponding beads. With the use of the body ply manufactured in this way in a tire, the resulting tire can be reduced in the manufacturing cost and weight.
