A crimp portion provided to a damping force adjustable shock absorber includes a crimp groove portion provided on an outer peripheral surface of a solenoid case along a circumferential direction thereof, and one end portion of a thin wall portion of a valve case that is contained while being bent in this crimp groove portion. The crimp groove portion includes an inclined surface inclined into a case 40 from a valve case side toward a solenoid case side. Due to this configuration, the damping force adjustable shock absorber can securely fix the solenoid case and the valve case by crimping while reducing a load on a solenoid block and a valve block due to the crimp fixation to a minimum load.

A shock absorber includes a hollow cylinder body extending in an up-down direction, a rod pipe located on an axis of the cylinder body, provided to be relatively movable in an axial direction of the cylinder body with respect to the cylinder body, and provided in a form of receiving a force in the axial direction, a rod-shaped support body extending inside the rod pipe with an upper end fixed, a stroke sensor including a coil and a conductor provided to be able to detect relative displacement of the rod pipe with respect to the support body, and a hollow intermediate member provided between the inner peripheral surface of the rod pipe and the support body to allow movement in the axial direction.

The damper assembly includes a tubular member, a rod, a primary piston, a secondary piston, and a resilient member. The tubular member includes a sidewall and a cap positioned at an end of the sidewall. The sidewall and the cap define an inner volume. The sidewall includes a shoulder separating the tubular member into a first portion and a second portion. The resilient member is disposed between the secondary piston and the cap and thereby is positioned to bias the secondary piston into engagement with the shoulder.

Embodiments of a hydraulic bump stop assembly may include a telescoping hydraulic cylinder containing hydraulic fluid. The telescoping cylinder may be located on a vehicle shock. Components of the shock may engage and compress the telescoping cylinder during the final stages of compression of the shock to prevent the shock from bottoming out. The telescoping cylinder has damping properties during compression and expansion due to hydraulic fluid being forced through orifices of one or more hydraulic fluid lines to and from a reservoir. Damping ratios may be adjusted by adjusting the size of the orifices. In some embodiments, the damping ratios may be adjusted remotely, such as from the driver compartment of the vehicle.
