    摘要： A spring clutch is provided for which durability is improved by preventing a clutch spring from breaking due to fatigue. A cylindrical clutch spring made from a wire having a square section is mounted between a pulley and a pulley hub mounted in the pulley. An end of the clutch spring is coupled to the pulley hub. A clutch surface is formed on the inner periphery of the pulley and is formed with a large-diameter recess at a position opposite to the end portion of the clutch spring including the torque transmission end. When the pulley rotates in one direction, the clutch spring expands. At this time, the end portion of the clutch spring including the torque transmission end expands in the large-diameter recess, thus relaxing sharp torque produced in the clutch. This prevents local stress concentration on the clutch spring and breakage of the clutch spring and improves the durability of the clutch.

    摘要： A friction type continuously variable transmission has double cones kept in contact with an input shaft and a drive cone and is capable of transmitting the rotation of the input shaft to an output shaft so that the output shaft rotates at a higher speed than the input shaft. A mechanism is provided for preventing the double cones from rotating about the input shaft and from coming off of their support shafts. A stay is mounted on a carrier supporting the double cones. The stay carries a guide roller bearing received in a guide fixed to a housing of the transmission. The stay thus prevents the rotation of the carrier while allowing only its axial movement. A stopper surface is provided at one end of the guide to restrict the axial movement of the carrier within a predetermined range.

    摘要： A drive device for an electric vehicle in which, by improving a supporting structure of an input shaft of a speed reduction unit, the bearing stiffness of a hub bearing is improved, while the rotational accuracy and the durability of an input shaft of a speed reduction unit are improved and noise is suppressed. The drive device includes: a speed reduction unit including an input shaft driven by an electric motor; a hub unit rotationally driven by the speed reduction unit; and a housing. The input shaft of the speed reduction unit is supported by bearings provided at two locations in the axial direction. The bearings are both supported by the output member, and the PCD of the inboard-side hub bearing of the hub bearings disposed at the two locations in the axial direction of the hub unit is larger than the PCD of the outboard-side hub bearing.

    摘要： A vehicular motor drive device is provided with an electric motor and a speed reducer having two gear trains capable of switching a fixed gear ratio. Driving force curves, which are determined depending on an output characteristic of the motor and represent a relationship between an output rotation speed in the respective gear train and an output torque, which is obtainable maximally at such output rotation speed, have a constant torque curve section, a gradually decreasing torque curve section and a constant speed curve section. The gear trains have respective speed reduction ratios such that the driving force curve of a gear train having a larger speed reduction ratio and the driving force curve of a gear train having a smaller speed reduction ratio continue to and partially overlap with each other in the gradually decreasing torque curve sections.
