Abstract

A pipe structure of a windshield washer fluid feeding device for a vehicle includes a refill pipe which is used for the feeding of windshield washer fluid into a windshield washer fluid reservoir tank and has a multiply-curved form ensuring a sufficient working space between the refill pipe and a head lamp unit of the vehicle, and an auxiliary pipe connected at both ends thereof to certain portions of the refill pipe. With the combined configuration of the refill pipe and auxiliary pipe, even if the windshield washer fluid freezes, a joint region between the windshield washer fluid reservoir tank and the refill pipe is protected from damage.

Claims

1. A pipe structure of a windshield washer fluid feeding device comprising:

a refill pipe having a multiply-curved shape so as to define a wide space between the refill pipe and a head lamp unit of a vehicle, the refill pipe being joined at one end thereof to a windshield washer fluid reservoir tank; and

an auxiliary pipe connected at both ends thereof to the refill pipe and integrally formed with the refill pipe.

2. The structure as set forth in claim 1, wherein the refill pipe includes:

a joining pipe which is joined to the windshield washer fluid reservoir tank and is extended upward in a vertical direction;

an inverse U-shaped pipe extending from the joining pipe;

a U-shaped pipe extending from the inverse U-shaped pipe; and

a vertical pipe extending upward in a vertical direction from the U-shaped pipe.

3. The structure as set forth in claim 1, wherein the auxiliary pipe communicates at the one end thereof with an uppermost portion of the inverse U-shaped pipe, and at the other end thereof with an upper end portion of the vertical pipe.

4. The structure as set forth in claim 2, wherein the auxiliary pipe communicates at the one end thereof with an uppermost portion of the inverse U-shaped pipe, and at the other end thereof with an upper end portion of the vertical pipe.
