1. A vehicle cleaner unit for cleaning a to-be-cleaned object mounted on a vehicle, the vehicle cleaner unit comprising:
a single motor;
a single pump comprising a cylinder extending in a longitudinal direction of the vehicle cleaner unit, air being introduced into the cylinder, and a piston capable of carrying out linear motion in the longitudinal direction inside of the cylinder and configured to blow the air outside of the vehicle cleaner unit at high pressure;
an urging spring configured to urge the piston toward a direction in which the piston is to move when blowing the air in the cylinder to the outside;
a single worm mechanism configured to transmit rotary motion of the single motor to cause the piston to carry out linear motion toward a direction opposite the direction in which the piston is to move when blowing the air in the cylinder to the outside;
a base member configured to support the to-be-cleaned object; and
a nozzle configured to spray the high-pressure air toward a cleaning surface of the to-be-cleaned object,
wherein a rotation axis of the single motor and the longitudinal direction are parallel to each other,
wherein the single motor, the single pump, and the urging spring are positioned entirely on the same side of the worm mechanism in the longitudinal direction, and
wherein a discharge port of the nozzle is provided on a face of the base member, which is opposite to a face of the base member on which the single pump and the single motor are provided, the base member being interposed therebetween.
