  • Publication number: 20240102552
    Abstract: A continuously variable transmission includes: a first pulley and a second pulley each including a fixed pulley and a movable pulley; and an endless member wound around the first pulley and the second pulley, wherein the continuously variable transmission continuously changes a speed ratio by controlling a thrust of the movable pulley with a hydraulic pressure, the thrust of the movable pulley is made smaller as a rotation speed of the first pulley decreases, and when the rotation speed of the first pulley is lower than a predetermined rotation speed, the thrust of the movable pulley in a case where the speed ratio is on a Low side of the predetermined speed ratio is not made smaller than the thrust of the movable pulley in a case where the speed ratio is on a High side of the predetermined speed ratio.

  • Publication number: 20230314987
    Abstract: A fixing device includes a pressure member, and a holder. The pressure member forms a pressure area between the pressure member and a fixing belt. The holder is provided inside the fixing belt, has a sliding surface in contact with an inner peripheral surface of the fixing belt via a lubricant, and holds a heater for heating the fixing belt. The holder includes a plurality of slits and a blocking portion. The plurality of slits are arranged in an axial direction on the sliding surface upstream of the pressure area in a passing direction of a medium and guide movement of the lubricant from upstream to downstream in a rotational direction of the fixing belt. The blocking portion restricts an outflow of the lubricant from each of the slits and restricts a fall of the fixing belt into each of the slits.

  • Publication number: 20230244168
    Abstract: A fixing device includes a fixing member, a pressure member, and a pair of retention members each including a restriction surface. The restriction surface restricts a movement of the fixing member in an axial direction. The restriction surface includes a first contact area and a second contact area. The first area is an area more on a downstream side of a passing direction of a medium than a center of a pressure area in the passing direction, and also closer to the pressure area than an apex of the fixing member on an opposite side of the pressure area. The first contact area and the second contact area are each tilted at a certain gradient so as to be set apart from the end portion of the fixing member in the axial direction from a side of the apex toward a side of the pressure area.
