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 is to provide an oil feed type auto-tensioner which can reliably prevent air from mixing into hydraulic oil in the pressure chamber.This tensioner includes a housing (11) defining a cylinder chamber (13), a plunger (14) slidably mounted in the cylinder chamber (13), a return spring (15) mounted in the cylinder chamber (13) and biasing the plunger (14) outwardly of the cylinder chamber (13), the housing (11) being formed with an oil supply passage (17) communicating with a pressure chamber (16) defined in the cylinder chamber behind the plunger (14), and a check valve (18) provided at a hydraulic oil outlet of the oil supply passage (17). The cylinder chamber (13) includes a large-diameter hole portion (19) provided at an open end thereof, in which a snap ring (20) for braking is received so as to be movable therein. The snap ring (20) includes a plurality of engaging pieces (20a) provided at a radially inner portion thereof and inclined in a direction in which the plunger (14) protrudes from the housing. The engaging pieces (20a) have radially inner edges that are in engagement with the outer periphery of the plunger, thereby restraining retraction of the plunger. When a pushing force is applied to the plunger (14) from the chain while the engine is at a stop, the snap ring (20) for braking abuts the closed end face of the large-diameter hole portion (19) and is stopped. In this state, because the radially inner edges of the engaging pieces (20a) formed on the radially inner portion of the snap ring (20) are in engagement with the outer periphery of the plunger (14), the plunger (14) is prevented from retracting, thus keeping the tension of the chain within a predetermined range. This prevents the plunger (14) from markedly moving outwardly when the engine is subsequently restarted.
