Abstract: A joint structure includes first and second engagement members, and an elastic member. The first engagement member includes a first body and a first engagement claw. The second engagement member includes a second body and a second engagement claw. The elastic member is disposed between the first and second engagement portions in a circumferential direction. When a relative rotation angle between the first and second engagement members is less than a predetermined angle, the first and second engagement claws are not in direct contact with each other in the circumferential direction, and a rotational force is transmitted through the elastic member while the elastic member is being elastically deformed. When the relative rotation angle is equal to the predetermined angle, the first and second engagement claws are in direct contact with each other in the circumferential direction.

Abstract: A sensor fault detection circuit includes: a first amplifier circuit that includes a first pair of elements operating reversely to each other, and amplifies a first sensor signal input from a first voltage amplifier; a second amplifier circuit that includes a second pair of elements operating reversely to each other, and amplifies a second sensor signal input from the second voltage amplifier; and a fault diagnosis unit that detects abnormality of a first voltage signal or a second voltage signal based on the first voltage signal output from the first amplifier circuit and the second voltage signal output from the second amplifier circuit. Characteristics of the first pair of elements are asymmetrical to each other, and characteristics of the second pair of elements are asymmetrical to each other in a same relationship with a relationship of the asymmetry between the characteristics of the first pair of elements.

Abstract: A damper includes a cylinder, a piston, a piston rod, a rod-side fluid chamber, a piston-side fluid chamber, an annular fluid chamber, and a stopper mechanism. The cylinder includes an inner tube and an outer tube. The rod-side fluid chamber is defined by the piston in the inner tube on a lower end side. The piston-side fluid chamber is defined by the piston in the inner tube on an upper end side. The annular fluid chamber is between the inner and outer tubes. At least one communication hole communicates the rod-side fluid chamber with the annular fluid chamber. A communication passage communicates the rod-side fluid chamber with the annular fluid chamber. A check valve in the communication passage allows fluid to flow from the annular fluid chamber to the rod-side fluid chamber and disallows the fluid to flow from the rod-side fluid chamber to the annular fluid chamber.

Abstract: A ball screw includes a nut, a screw shaft, an end deflector attached to the nut, plural balls, and a pair of ball lifting portions. A spiral groove is formed at an outer peripheral surface in the screw shaft. The plural balls roll along the spiral groove. The pair of ball lifting portions is provided at the end deflector so as to interpose a width center of the spiral groove. The pair of ball lifting portions supports the balls by a first part of one of the pair of ball lifting portions and a second part of other of the pair of ball lifting portions being apart from each other in a width direction of the spiral groove so as to interpose the width center of the spiral groove between the first and second parts to thereby lift the balls from the spiral groove.
