PROBLEM TO BE SOLVED: To provide a vehicle-use cleaning device featuring excellent operability and unique design capable of composing the cleaning device in a small shape. SOLUTION: This vehicle-use cleaning device 100 is equipped with: a cylinder 110, designed to supply purification liquid from one end thereof; a piston 120, designed to have a purification channel 121 inside and linked to the cylinder 110 in a free slidable manner; the 1st spring means 130 arranged to fix the piston pressingly to one end of the cylinder; a shut-off valve 140 formed at one end of the piston; and a jet nozzle 150 formed at the other end of the piston and designed to have a jet port 152, which is aligned with the purification liquid channel within the piston. In this cleaning device 100, one end of the shut-off valve is connected with the internal surface of the cylinder, while its other end is equipped with a sealant 141, which is connected with the external surface of the piston, and which clogs ports 123 formed at one end of the piston, thereby blocking passages with the interior of the cylinder. After the piston is protruded to a fixed position from the other end of the cylinder, the sealant opens the aforementioned ports on the cylinder, thereby forming purification liquid channels from the cylinder through the interior of the piston to the jet nozzle.
