In an inline skate comprising a wheel frame provided with a rear wheel fixed axle at a rear portion thereof, a rear axle at a rear portion thereof, an intermediate fixed axle arranged between the rear wheel fixed axle and the rear axle, and a shock absorbing structure mounted between the rear wheel
In an inline skate comprising a wheel frame provided with a rear wheel fixed axle at a rear portion thereof, a rear axle at a rear portion thereof, an intermediate fixed axle arranged between the rear wheel fixed axle and the rear axle, and a shock absorbing structure mounted between the rear wheel fixed axle, the rear axle and the intermediate fixed axle, the improvement wherein the shock absorbing structure comprises a front absorber and two rear absorbers, the front absorber comprising a first tubular member made of foamed plastic, two retainer rings each having an inner end slidably fitted into an end of the tubular member, and a first spring fitted inside said first tubular member and bearing against the two retainer rings, the two retainer rings being connected between the intermediate fixed axle and the rear wheel fixed axle, and each of the rear absorber comprising a second tubular member having an open end, a second spring fitted inside the second tubular member, a piston fitted inside the tubular member and formed with a plurality of axial though holes, a rod extending into the second tubular member to engage with the piston, a hydraulic fluid filled into the tubular member, a cover threadedly engaged with an open end of the tubular member, and a retainer threadedly engaged with an outer end of the rod.
