In a continuously variable transmission, a hydraulic actuator for axially moving a movable sheave has an outer cylinder which includes a radial portion extending radially from a boss on the stationary sheave. A bearing is disposed abutting the surface of the radial portion. The inner race of the bearing has a large diameter so that the inner race contacts at least a predetermined area of the surface of the radial portion, preferably, the entire area of that surface. One side of the inner race has a recess in which a nut for axially fixing the outer cylinder, the bearing and the like is disposed, thereby reducing the axial dimension of the continuously variable transmission.

First and second refrigerating circuits respectively cause first and second adsorbing bodies to alternately adsorb and release first and second coolants. In the first refrigerating circuit, when the first adsorbing body is heated, it releases the first coolant. The released first coolant is cooled, and discharged through an expansion valve so that a part of the first coolant is liquefied. The resultant latent heat of vaporization can be utilized to cool an object to be cooled. Thereafter, the first coolant is adsorbed when the first adsorbing body is cooled. In the second refrigerating circuit, when the second adsorbing body is heated, it releases the second coolant. The released second coolant is cooled by a liquefied-gas-type cooler, and discharged through an expansion valve so that a part of the second coolant is liquefied. The resultant latent heat of vaporization is utilized to cool the first adsorbing body of the first refrigerating circuit. Thereafter, the second coolant is adsorbed by the second adsorbing body. The liquefied-gas-type cooler cools the second coolant by utilizing the latent heat of vaporization of a liquefied gas. Thus, the amount of the second coolant liquefied after being discharged through the expansion valve in the second refrigerating circuit is increased.

A vehicle has a rotary magnetic field member which is rotatably supported at a position near the surface of a roadway along which the vehicle runs and rotatingly driven by a driving device. The rotary magnetic field member has magnetic poles of different polarities alternately arranged around its circumference. The vehicle also has an electrical power collector for receiving electrical power from an electrical power supply associated with the roadway. The received electrical power is supplied under the control of a controller to the driving device thereby rotatably driving the rotary magnetic field member. The rotary magnetic field member when rotated relative to the roadway made of an electrically conductive non-magnetic material, forms a varying magnetic field in cooperation with the roadway, thereby generating propulsion force for propelling the vehicle and force for suspending the vehicle, so that the vehicle is propelled in a floating state. It is therefore possible to reduce friction between wheels of the vehicle and the roadway and, hence, to suppress wear of the wheels. In a high-speed transportation system of the invention, the electrical power collector picks up electrical power from the electrical power supply and the rotary magnetic field member is rotatingly driven by the power picked up by the electrical power collector.

A vehicle with a noncontact drive mechanism includes a magnetic propelling device 7 for generating a propelling force derived from magnetic induction of an eddy current within a reaction plate 4 laid on a road surface, without contact between the magnetic propelling device and the reaction plate; a flux changing device 13 for changing magnetic flux of the magnetic propelling device; a chassis supporting device for holding a chassis with respect to the road surface; and running-direction control devices 3, 5 for controlling the direction of running of the vehicle. The vehicle is adapted to run by generating a magnetic force in noncontact with the reaction plate. The vehicle further includes a plurality of wheels 2 for supporting the chassis on the road surface and a wheel drive device for driving at least one of the wheels, so as to permit running by making use of magnetic propelling force in noncontact with the reaction plate and by making use of a frictional force through friction between the road surface and the wheels. The vehicle is capable of running on any road surface so as to enhance the degree of its freedom, and is capable of reducing tire wear. Also disclosed is a transportation system using the vehicle.
