    摘要： An endless belt (11) to be provided on a driven pulley (4b) and a pulley rotation support apparatus for supporting the driven pulley (4b). In the pulley rotation support apparatus, there is used a three-point-contact-type or four-point-contact-type radial ball bearing (14b). An offset quantity δ, which is an axial-direction distance between the center α of a radial load applied from the endless belt (11) to the driven pulley (4b) and the center position β of the radial ball bearing (14b), is set 40% or less of the pitch circle diameter of the radial ball bearing (14b). The radial clearance of this radial ball bearing (14b) is set 0.2% or less of the above pitch circle diameter.

    摘要： A double-row angular contact ball bearing is provided with inner and outer rings, balls in two rows, a cage for holding the balls, and non-contact sealing devices made of a substantially disc-like member. Radial outer end portions of a metallic sealing device are respectively fit and swaged into grooves arranged at both axial end portions of the outer ring's inner circumferential surface. The ratio Ts/Tr is equal to or lower than 0.07, where Ts is the sealing device thickness and Tr is the outer ring thickness at the bottom portion of the groove. In addition, the ball diameter is equal to or greater than 75% of a half a bearing width to equal to or greater than 83% thereof. Furthermore, an axial width Tc of the radial outer end portion having a substantially U-shape is equal to or smaller than 2.7 mm.

    摘要： The object of the invention is to provide a structure which not only can be reduced in size but also can secure the durability of an endless belt (11) to be provided on a driven pulley (4b) and a pulley rotation support apparatus for supporting the driven pulley (4b). In the invention, as the above pulley rotation support apparatus, there is used a three-point-contact-type or four-point-contact-type radial ball bearing (14b). An offset quantity δ, which is an axial-direction distance between the center α of a radial load applied from the endless belt (11) to the driven pulley (4b) and the center position β of the radial ball bearing (14b), is set 40% or less of the pitch circle diameter of the radial ball bearing (14b). The radial clearance of this radial ball bearing (14b) is set 0.2% or less of the above pitch circle diameter.
