A housing case that houses a fuel cell is provided with mounts for fixing two ends of a lower surface of an end plate that retains stacked unit cells of the fuel cell, and a mount for fixing a central portion of a lower surface of another end plate. Using these three mounts, the fuel cell is fixed to the housing case.

A four-wheel steering system for an automotive vehicle includes a front wheel steering mechanism operable in response to a steering effort applied thereto to steer a pair of dirigible front road wheels, a rear wheel steering mechanism arranged to steer a pair of dirigible rear road wheels in response to steerage of the front road wheels, and a control apparatus arranged to control the rear wheel steering mechanism in such a manner that the rear road wheels are retained in their neutral positions when the front road wheels are steered at an angle less than a predetermined small angle and that the rear road wheels are steered in an opposite direction relative to the front road wheels when the front road wheels are steered at a larger angle than the predetermined small angle. The control apparatus is further arranged to control the rear wheel steering mechanism in such a manner that a changing rate of the rear wheel steering angle per a unit steering angle of the front road wheels increases in accordance with an increase of the front wheel steering angle.

Four-wheel steering system for automotive vehicles

A four-wheel steering system for an automotive vehicle in which a cable linkage is adapted to operatively interconnect front and rear wheel steering mechanisms. The cable linkage is provided with a displacement transmitting mechanism which includes an input element operatively connected to a front lateral bar in the front wheel steering mechanism through the cable linkage, an output element operatively connected to the rear wheel steering mechanism, and a spring element disposed between the input and output elements to transmit displacement of the input element to the output element without any deflection in a condition where the output element is freely movable and to absorb displacement of the input element in a condition where the output element is restrained by an excessive load applied thereto from the rear wheel steering mechanism.

A linear expansion or contraction of a piezoelectric element (150) is converted into a corresponding magnified linear movement of an output member (120) along a central axis (34) by a series combination of a pair of magnifying lever arms (100, 102) supported from a retainer structure (52) via a pair of elastic integral hinges (96, 98) and a pair of links (110, 112; 206, 208) wherein the retainer structure is enclosed in a housing (38) and adjustably fastened thereto so as to be adjustably shiftable relative thereto along the central axis.

This controller controls a varible damping force shock absorber taking the cycle time and the oscillating phase of the body vibration. The controller increases the damping force when the body is moving toward its mean position. Before that, the damping force is kept weak so that the body vibration is hastened to become moving toward the mean position. Some criteria for determining that the body is moving toward its mean position are proposed.
