Claims

[Scope of utility model registration request]

A hydraulic response device for tilting, which is interposed between the cab and the body frame of the truck, and rotates the cab up or down around a pivot at a lower front end portion of the cab by relative expansion and contraction of a piston shaft and a cylinder; A column installed in parallel with the hydraulic displacement device and displaced with respect to the vehicle body frame together with the device, and a column 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. a locking device that also prohibits 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 completes a predetermined extension stroke; and an electrical alarm device such as a buzzer connected in parallel to the electric motor energizing circuit; A cab tilt device for a truck, characterized in that a normally closed alarm control switch is provided which opens when the locking device engages with a support column and performs a locking function.
