Abstract

A vehicle cleaning apparatus includes a nozzle configured to jet fluid toward an object to be cleaned; a cover configured to cover at least a part of the nozzle; a valve configured to open and close a channel of the fluid; and a holder including a valve disposition portion in which at least a part of the valve is disposed, and a cover attachment portion to which the cover is attached. The cover attachment portion is formed integrally with the valve disposition portion.

First claim

What is claimed is:

1 . A vehicle cleaning apparatus comprising:
a nozzle configured to jet fluid toward an object to be cleaned; a cover configured to cover at least a part of the nozzle; a valve configured to open and close a channel of the fluid; and a holder including a valve disposition portion in which at least a part of the valve is disposed, and a cover attachment portion to which the cover is attached, wherein the cover attachment portion is formed integrally with the valve disposition portion.

2 . The vehicle cleaning apparatus according to claim 1 , further comprising
a piston which is movable in an axial direction with respect to a cylinder and in which the fluid flows, wherein: the holder further includes a piston coupling portion that is coupled to the piston; and the valve disposition portion and the piston coupling portion are integrally formed.

3 . The vehicle cleaning apparatus according to claim 2 , wherein:
the holder further includes a nozzle holding portion configured to hold the nozzle; the valve disposition portion and the piston coupling portion are provided to be continuous with each other in the axial direction; and the nozzle holding portion is projected from the valve disposition portion in a different direction from the axial direction.

4 . The vehicle cleaning apparatus according to claim 3 , wherein:
a plurality of the nozzle holding portions and a plurality of the nozzles are provided; and the plurality of the nozzle holding portions are projected from the valve disposition portion toward opposite sides in a direction orthogonal to the axial direction.

5 . The vehicle cleaning apparatus according to claim 2 , wherein a part of the valve is disposed in the piston coupling portion.

6 . The vehicle cleaning apparatus according to claim 1 , wherein:
an air flow hole is provided, and outside air is taken into the holder through the air flow hole to cause the valve to operate; and the air flow hole is covered by the cover.

7 . The vehicle cleaning apparatus according to claim 6 , wherein:
a cap that closes an opening of the valve disposition portion is attached to an inner peripheral surface of the cover attachment portion; and the air flow hole is provided in the cap.

8 . The vehicle cleaning apparatus according to claim 1 , wherein the valve is elastically deformable.
