Claims

[Scope of utility model registration request]

, is interposed between the truck cab and the vehicle body frame,
A tilting hydraulic response device that rotates the cab up or down around a pivot at a lower front end portion by relative expansion and contraction of the piston shaft and the cylinder, and a tilting hydraulic response device that is installed in parallel with the hydraulic response device and attached to the vehicle body frame together with the device. On the other hand, a displaceable column, a locking device provided between the hydraulic response device and the column and engaged with the column when hydraulic oil is lost when the hydraulic response device is extended to inhibit contraction of the hydraulic response device; An electric motor that drives a hydraulic pump that supplies hydraulic oil to the hydraulic response device, a main switch that is arranged in series in the energizing circuit of the electric motor and that is manually opened and closed by the operator, and the hydraulic response device. an extension detection switch that opens when the electric motor has completed a predetermined extension stroke; an electrical alarm device such as a buzzer connected in parallel to the electric motor energizing circuit; A cab tilt device for a truck, comprising an alarm control switch that is open when the lock device is operatively engaged with the column and closed when the lock device is not engaged.
