Claims

[Scope of utility model registration request]

A cylinder whose base end is pivotally attached to the chassis frame side of a cab-over-engine vehicle, and a piston rod that is fitted into the cylinder chamber of the cylinder so as to be slidable in the vertical direction, and whose upper end is pivotally attached to the cab side. a check valve consisting of a piston and a spring that presses the valve body downward; and a check valve that communicates with the cylinder chamber so as to open the check valve when the piston descends. A check valve opening piston slidably disposed in a hollow chamber, a communication pipe that communicates the lower side of the check valve opening piston with the cylinder chamber above the piston, and a hydraulic pump. a first oil pipe connected in communication with the hydraulic pump and the hollow chamber below the check valve opening piston; and a first oil pipe connected to the hydraulic pump and the hollow chamber above the check valve opening piston. and a second oil pipe connected in communication with each other. A cab tilt device characterized in that the oil pipe is provided with a throttle valve that limits the amount of oil discharged when the cab is lowered.
