Claim 0:
1. A vehicle cleaner unit comprising:
a cylinder unit comprising a cylinder configured to form therein a chamber, a discharge port through which the chamber communicates with an outside, and a piston configured to reciprocate inside of the cylinder to discharge from the discharge port a cleaning medium inside of the chamber;
a power unit comprising a motor, a power transmission mechanism configured to transmit rotary motion of the motor to the piston to cause the piston to reciprocate, and a housing configured to house therein the motor and the power transmission mechanism; and
a casing configured to house the cylinder unit and the power unit,
wherein the cylinder unit and the power unit are supported to the casing with a first rubber member and a second rubber member being interposed therebetween,
wherein the first rubber member is provided at one end surface of the casing and the second rubber member is provided at the other end surface of the casing in a reciprocation direction of the piston,
wherein the first rubber member is interposed between the cylinder unit and the casing, and the second rubber member is interposed between the power unit and the casing,
wherein the first rubber member includes:
a first large-diameter part attached to the casing,
a first small-diameter part attached to the cylinder unit, and
a first connection part configured to interconnect the first large-diameter part and the first small-diameter part,
wherein the second rubber member includes:
a second large-diameter part attached to the casing,
a second small-diameter part attached to the power unit, and
a second connection part configured to interconnect the second large-diameter part and the second small-diameter part,
wherein a stiffness of the first connection part is smaller than the stiffness of the first large-diameter part and the stiffness of the first small-diameter part,
wherein the stiffness of the second connection part is smaller than the stiffness of the second large-diameter part and the stiffness of the second small-diameter part,
wherein the first connection part is thinner than the first large-diameter part and the first small-diameter part in the reciprocation direction, and
wherein the second connection part is thinner than the second large-diameter part and the second small-diameter part in the reciprocation direction.
