Brake/shock-absorber seat structure of handle-controlled skate board. The front ends of rear wheel brackets are pivotally connected with a lower bar of rear section of the skate board by a shaft pin. The bottoms of front sections of the rear wheel brackets are connected by a connecting plate. A projecting circular receptacle is formed in the connecting plate. The rear wheel brackets are formed with through holes behind the receptacle. A rear wheel is pivotally connected with the rear portions of the rear wheel brackets. The wheel cover is locked on the middle portion and rear end of the rear wheel brackets. The middle portion of the wheel cover is equipped with a brake structure. One end of the shock-absorbing spring abuts against the bottom face of the skate board. The other end thereof is received in the receptacle of the connecting plate of the rear wheel brackets. The restricting slide rail is locked on the locking plates of the skate board. A lower section of the slide rail is formed with a blind arch rail slot. A pin member is passed through the through holes of the rear wheel brackets and the slide slot of the restricting slide rail. The rear wheel brackets are movable through an arch path along the rail slot of the restricting slide rail about the shaft pin at front end of the rear wheel brackets, whereby the rear wheel brackets can only move up and down without deflecting left or right so as to achieve a true shock-absorbing effect.
