    • The universal joint of this invention comprises a hub interposed between an upper shaft and a middle shaft, an upper pin coupling together the upper shaft and the hub, a lower pin coupling together the middle shaft and the hub, and a stopper ring fitting over the outside of the middle shaft at an end thereof on the side of the upper shaft. The hub is formed in such a manner that the outer shape thereof is a spindle shape narrowing in the fore-and-aft direction with respect to the upper pin, and a bottomed hole provided with a taper portion is formed in the axial center thereof, opening towards the rear of the upper pin. In a front end portion of the upper shaft are formed a taper portion contracting towards the front of the upper pin and a groove portion engaging with the lower pin. The upper and lower pins are disposed adjacent to one another in the central axial direction of the hub and are also at a phase angle difference of, for example, 90 degrees. This invention provides a universal joint that has a simpler structure and a reduced manufacturing cost.

    • A vehicle speed responsive power steering apparatus enables a pressure which acts upon a power cylinder to be variably controlled in accordance with a vehicle speed or the like, thus allowing an assisting force to be controlled in a variable manner. A control valve CV selectively connects a pump P and a tank T to left and right chambers CL, CR of a power cylinder. The control valve comprises a first and a second fluid pressure bridge circuit 10, 20. The first fluid pressure bridge circuit includes a left and a right path 12, 13, in which a first and a second pair of variable throttles 1R, 1L and 2L, 2R are disposed which are opened or closed in response to a steering operation. The left and the right chamber of the cylinder are connected to the respective paths at the junctions between the variable throttles. A pair of paths 21, 22 branch from a supply path 11 extending from the pump, and a second fluid pressure bridge circuit is defined between the paths 21, 22, in parallel relationship with the first fluid pressure bridge circuit. The second fluid pressure bridge circuit includes variable throttles 3L, 3R, 4R, 4L which are opened and closed in response to a steering operation, and a vehicle speed responsive variable throttle valve 6 which is controlled to be opened or closed in accordance with a vehicle speed.

    • A power steering apparatus includes a main hydraulic path, a reactive oil pressure supply path, and a hydraulic reaction mechanism. The main hydraulic path supplies an oil pressure from a pump to a flow path switching valve connected to a power cylinder. The reactive oil pressure supply path branches from a portion of the main hydraulic path. The hydraulic reaction mechanism introduces part of the oil pressure, caused to diverge by the reactive oil pressure supply path, into a hydraulic reaction chamber for generating a steering reaction through a hydraulic reaction control valve mechanism controlled in accordance with the traveling conditions of a vehicle. A restriction smaller in diameter than the main hydraulic path is arranged between a branch portion branching from the main hydraulic path and the hydraulic reaction control valve mechanism, midway along the reactive oil pressure supply path.
