SOLUTION: A cylindrical recessed and curved surface 30d having a radius of curvature r1 is formed in a rocking member 30 formed at one end of the rocker arm, and a cylindrical protruded and curved surface 14d having a radius of curvature r2 smaller than that of the cylindrical recessed and curved surface 30d and the center of curvature coincides with that of the cylindrical recessed and curved surface 30d is formed in a hydraulic adjuster member 14 for supporting the rocking member 30. The cylindrical protruded and curved surface 14d is disposed facing the cylindrical recessed and curved surface 30d with a gap therebetween. A plurality of cylindrical rollers 16 are arranged between the cylindrical recessed and curved surface 30d and the cylindrical protruded and curved surface 14d. The cylindrical rollers 16 are configured to make rolling contact with the cylindrical protruded and curved surface 14d and the cylindrical recessed and curved surface 30d when the rocker arm rocks. There is provided a rolling area 17a for allowing the rollers 16 to roll at a rolling angle of θ=α×r1/(r1+r2) when the rocking angle of the rocker arm is set at α.

摘要： PROBLEM TO BE SOLVED: To provide a coated member coated with a surface coating that can greatly improve wear resistance or improve a sliding characteristic (a reduction in friction coefficient).SOLUTION: A coated member is formed of a base material and a surface coating which coats at least part of a surface of the base material. The surface coating is formed of TiC and columnar fine particles whose grain sizes are 1-90 nm are distributed over the outermost surface. Amorphous carbon may be included in the surface coating. The surface coating, which does not substantially include the amorphous carbon and is formed of column particles in which grain growth occurs from the outermost surface of the base material to the outermost surface of the surface coating, shows extremely high wear resistance. Such a surface coating formed of the TiC is, e.g., obtained by plasma CVD. One example of the coated member is a molding die.

摘要： PROBLEM TO BE SOLVED: To provide a continuously variable transmission reducing the deformation of sheaves without increasing the size thereof.
SOLUTION: The continuously variable transmission includes a plurality of pulleys 10, and a transmission belt 20 bridged among the plurality of pulleys 10. Each pulley 10 includes a pulley shaft 12, a fixed sheave 14 fixed to the pulley shaft 12, and a movable sheave 16 movable forward and backward along the pulley shaft 12. The fixed sheave 14 and the movable sheave 16 are arranged opposing each other, and a width-variable pulley groove 18 is formed between both sheaves 14, 16. Annular ribs 17 are protruded on back faces 14b, 16b of the sheaves 14, 16. The annular ribs 17 prevent an increase in the thicknesses of the sheaves 14, 16 and thus improve the rigidity of the sheaves 14, 16 while preventing an increase in the size of the transmission. This results in reducing the deformation of the sheaves 14, 16.
