PURPOSE: Structure of a cap tilt cylinder of a truck is provided to prevent an accident by preventing a cap from rapidly descending in cap tilting-down of the truck. CONSTITUTION: Structure of a cap tilt cylinder(14) of a truck has the cap tilt cylinder to which a rod head(15) vertically operating by hydraulic pressure is installed. The rod head is hinged with a supporting plate installed under a cap. The structure of the cap tilt cylinder forms a lost motion part(LM) the internal diameter of which gets wider from the upper side toward the lower side in the cap tilt cylinder. Semi-circular pipes(20) are oppositely inserted in the lost motion part. A solenoid device(30) is installed to the outer peripheral surface of the semi-circular pipe. The solenoid device operates according to a power signal of an electrically driven pump, and expands and reduces the internal diameter of the semi-circular pipes.
