    摘要： A damper includes a cylinder into which magneto-rheological fluid is sealed, a first fluid chamber and a second fluid chamber, a throttle passage, an electromagnetic coil, and a spacer. The first fluid chamber and the second fluid chamber are partitioned by a piston core in the cylinder. The throttle passage is formed between an inner peripheral surface of the cylinder and an outer peripheral surface of the piston core. The throttle passage communicates between the first fluid chamber and the second fluid chamber. The throttle passage provides a resistance to a flow of the passing magneto-rheological fluid. The electromagnetic coil generates a magnetic field acting on the magneto-rheological fluid flowing through the throttle passage. The spacer is mounted to the piston core and is configured to adjust a length of the throttle passage.

    摘要： Provided is a unidirectional shock absorber without losing a damping force reducing effect even with continuous input of high-frequency vibrations. A shock absorber includes: a piston partitioning a cylinder into an extension chamber and a compression chamber; a pressure chamber; a free piston slidably inserted into the pressure chamber; a spring element; an extension chamber-side passage; a compression chamber-side passage; a valve provided to the extension chamber-side passage and configured to offer resistance to a flow from a side closer to the extension chamber to a side closer to the compression chamber; and a check valve provided in parallel with the valve, allowing only a flow from the side closer to the compression chamber to the side closer to the extension chamber, wherein the shock absorber generates a damping force only at the time of elongation.

    摘要： A shock absorber includes at least one of an expansion-side sensitive unit and a contraction-side sensitive unit. The expansion-side sensitive unit has an expansion-side actuating chamber that communicates with an expansion-side chamber and a contraction-side chamber, an expansion-side free piston that partitions the expansion-side actuating chamber into a first expansion-side pressure chamber and a second expansion-side pressure chamber, and an expansion-side spring element configured to bias the expansion-side free piston to compress the first expansion-side pressure chamber. The contraction-side sensitive unit has a contraction-side actuating chamber that communicates with a contraction-side chamber and a reservoir, a contraction-side free piston that partitions the contraction-side actuating chamber into a first contraction-side pressure chamber and a second contraction-side pressure chamber, and a contraction-side spring element configured to bias the contraction-side free piston to compress the first contraction-side pressure chamber.

    摘要： A rotation lock is provided to a piston rod, a collar is fitted on a small-diameter portion disposed on an end portion on a side of the piston rod extending from a cylinder, and the collar is press-fitted onto a press-fitted portion disposed on the piston rod by a press-fitting jig screwed with an external thread formed on the small-diameter portion. The press-fitting jig adds an axial force to the collar.

    摘要： An electric actuator is capable of easily achieving reduction in weight and size when compared to a hydraulic cylinder device, capable of being used in place of the hydraulic cylinder device, and capable of freely extending in response to a suddenly-applied impact load. An electric actuator converts rotation of an electric motor into advancing/retracting motion of an output rod using a screw shaft and a nut member mounted to the screw shaft. The output rod includes: a drive cylinder, to which the nut member is provided, the drive cylinder being arranged around the screw shaft; and a movable cylinder arranged to overlap the drive cylinder around the screw shaft and freely advancing and retreating with respect to the drive cylinder. The electric actuator further includes a releasing mechanism provided between the drive cylinder and the movable cylinder, for engaging the movable cylinder with the drive cylinder.
