[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washer tank for a vehicle, and more particularly to an improvement in a mounting structure of a water supply pipe extending upward from a tank body through a hole provided in a panel on a vehicle body.

[0002]

2. Description of the Related Art To increase the stability of a water supply pipe extending upward from a tank body through a hole provided in a panel on the vehicle body side, a tongue piece is provided at an upper end of the water supply pipe and fixed to the vehicle body side. I just need. However, when the tongue is provided at the upper end of the water supply pipe as described above, it is necessary to provide a large hole through which the tongue passes through the panel on the vehicle body side, so that the strength of the panel is reduced. There is a problem that.

In order to solve such a problem, for example, as shown in Japanese Utility Model Application Laid-Open No. Sho 62-163170, a flat C-shaped band portion is provided on a bracket, and a water supply pipe extending upward from the tank body. It is effective to hold the upper end of the squeezing force with the band portion.

[0004] However, in order to securely engage the bracket with the water supply pipe using the flat C-shaped band as described above, it is necessary to provide a band having a length that is equal to or more than half the outer circumference of the water supply pipe. In addition, it is necessary to bend and extend the distal end opening of the band outward to facilitate the operation of inserting the water supply pipe into the band. Further, the fixing strength of the water supply pipe by the bracket changes depending on the pinching strength of the band portion, and the pinching strength of the band portion depends on the length of the band portion.

[0005] Therefore, in order to increase the fixing strength of the bracket, it is necessary to lengthen the band portion. When the length of the band portion is increased in this way, the width of the opening is reduced, and the workability of coupling with the water supply pipe is improved. However, there is a problem that it is necessary to increase the working space by an amount corresponding to the outwardly extending and extending portion provided in the opening at the distal end of the band portion.
