摘要： A hydraulic autotensioner has a cylinder having a closed bottom end, a sleeve mounted in the cylinder and a plunger slidably mounted in the sleeve. The interior of the cylinder is divided into a reservoir chamber and a pressure chamber by the plunger which is formed with a passage through which the reservoir chamber and the pressure chamber communicate with each other. A check valve is provided in the passage to close the passage if the pressure of hydraulic oil in the pressure chamber increases above the pressure of hydraulic oil in the reservoir chamber. A return spring is mounted in the cylinder to bias a rod which is axially movable together with the plunger in such a direction as to protrude from an upper opening of the cylinder. The return spring is mounted in a space formed between the outer peripheral surface of the sleeve and the inner peripheral surface of the cylinder.

摘要： A chain tensioner keeps constant the tension of a chain for transmitting the rotation of an engine crankshaft to e.g. camshafts. It includes a housing having a cylinder chamber. A rod member has its rear end inserted in the cylinder chamber for pressing a chain. A tension adjusting spring biases the rod member outwardly of the housing. The chain tensioner further includes a hydraulic damper for damping a dynamic load applied to the rod member from the chain, and a thread engagement mechanism for preventing the rod member from retracting under a static load applied to the rod member.

摘要： An autotensioner having a fixed shaft, a pulley support pivotally supported on the fixed shaft, a pulley rotatably supported on the pulley support and a spring for biasing the pulley support in such a direction as to apply tension to a belt. The pulley support has a cylindrical portion arranged coaxially with the fixed shaft. The fixed shaft is formed with cam surfaces at such a position that wedge-shaped spaces are defined between the cam surfaces and the cylindrical portion. The wedge-shaped spaces narrow in a direction in which the pulley support pivots to slacken the belt. Friction members are each mounted in the respective wedge-shaped spaces. They have a shape substantially complementary to the shape of the wedge-shaped spaces. A spring member is also mounted in each wedge-shaped space to bias the friction members into the narrow area of each wedge-shaped space.

摘要： A wheel driving device includes a speed reducer for transmitting rotation of an electric motor to a hub ring supporting a vehicle wheel after reducing its speed. The speed reducer is a cycloid speed reducer including an external gear, and an internal gear meshing with the external gear and rotationally fixed to the speed reducer casing through a rotational fixing arrangement which is also capable of elastically supporting the internal gear. The rotational fixing arrangement absorbs, by elastic deformation, vibration of the internal gear due to torque transmitted from the external gear to the internal gear, thereby preventing the vibration of the internal gear from being transmitted to the speed reducer casing.

摘要： A ceramic heater is constructed by embedding a heat-generator in a base body made of ceramics. The heat-generator has a recess in a surface thereof, the ceramics being inside the recess. Even if a great thermal stress is developed due to a difference in thermal expansion between the heat-generator and the base body, by the recess inside which the ceramics that forms the base body exists, occurrence of a gap between the heat-generator and the base body, as well as appearance of cracks in the base body, can be prevented even in the direction of the length of the heat-generator in which the thermal stress is applied heavily.

摘要： An object of the invention is to always maintain an outer pin holder and a housing in a speed reducer section at their predetermined positions, to prevent damage to such components as revolving members, outer circumferential engagers, and motion conversion mechanism upon a large axial load due to turning or sudden acceleration/deceleration, etc., and to eliminate rattling noise caused by the housing and the outer pin holder. A casing immobilizing member which is fixed to an inner surface of a speed reducer section casing and a housing immobilizing member which is fixed to an outer surface of a speed reducer section housing are provided between the speed reducer section casing and the speed reducer section housing. The casing immobilizing member and the housing immobilizing member are bonded with each other via a rubber member.

摘要： A vane pump includes a casing and a rotary unit rotatably held within the casing. The rotary unit includes a base portion with radially outwardly opened slits extending radially with respect to a rotational axis of the rotary unit and vanes slidably fitted in the respective slits. An annular chamber is formed around the base portion within the casing and divided into a plurality of pump chambers by the vanes. Each of the pump chambers has a volume cyclically expanded and contracted during rotation of the rotary unit to discharge the fluid drawn into each of the pump chambers. The casing includes an inlet port through which to draw the fluid into the annular chamber. The inlet port is arranged to face a portion of the annular chamber extending between a middle position and a terminating position of an expanding section in which each of the pump chambers expands.
