A remote operation type damping force control mechanism for a hydraulic damper including a cylinder, a piston, and a hollow piston rod having therein an oil path interconnecting a pair of chambers separated from each other by the piston in the cylinder. The mechanism comprises an adjustment rod rotatably inserted in the hollow piston rod and provided at the inner end thereof with an orifice plate having a plurality of orifices of different diameters, a remote operation part provided with an operation member, a control cable operatively integrally connected with the operation member and lead out of the remote operation part, and a driving mechanism interposed between the control cable and the adjustment rod for driving to rotate the adjust rod in accordance with the rotation of the operation member of the remote operation part. The driving mechanism has a plurality of first pins projectingly provided on an end face of the adjustment rod and a single second pin integrally jointed with the distal end of the control cable and perpendicularly engageable with the first pins.

A spring load adjusting device for cushioning equipment including a pressure chamber which hydraulically controls a spring load of a coil spring. A hydraulic cylinder is hydraulically connected to the pressure chamber, a piston is slidably fitted in the cylinder, an adjust screw is provided for sliding the piston, and a protection member is provided for protecting a threaded portion of the adjust screw. The threaded portion of the adjust screw is protected from exposure to the outside and is thus protected from dust and the like, while the appearance is improved.

A front wheel suspension system for a motorcycle including a telescopic hydraulic shock absorber mechanism which provides an anti-dive function upon braking of a front wheel of the motorcycle. In addition to a main oil passage which is intercepted upon braking of the front wheel, a bypass oil passage is provided between inner and outer tubular members comprising a fork pipe and a bottom case, respectively, disposed in a telescopically fitted relationship with each other. An adjustable orifice mechanism is provided in an intermediate position in the bypass oil passage. The suspension system provides an appropriate adjustment of the damping effect of the shock absorber mechanism in a direction of contraction of a front fork upon an anti-dive operation.
