Embodiments disclosed herein provide a vehicular active shock absorber in which two variable valves is able to be operated by one solenoid, a tube connecting a damping force-variable valve and the pump is not subjected to a bending force and is not expanded, and a space of a compression chamber is small. According to the embodiments, there is provided a vehicular shock absorber including: a damper including a cylinder, a piston valve disposed inside the cylinder, and a piston rod, of which one end is connected to the piston valve and a remaining end is connected to a vehicle body; a damping force-variable valve assembly attached to an outer portion of the damper and configured to regulate a flow of the working fluid of the damper; a pump fixed to the vehicle body; and a tube configured to make the pump and a piston road flow path provided in the piston rod communicate with each other. The piston rod flow path makes the tube and an extension chamber of the damper communicate with each other.
