PROBLEM TO BE SOLVED: To provide a watering tube which suppresses dispersion in the amount of water supply for each water supply hole.SOLUTION: The watering tube includes: a main pipe 10 which has a liquid conveying passage 11 and a branch pipe 20 which is provided at a periphery of the main pipe 10 and has a communicating hole 21 provided between the liquid conveying passage 11 and the main pipe, a water supply hole 22 which is headed toward the outside, and a water supply channel 23 which extends between the communicating hole 21 and the water supply hole 22. The water supply channel 23 contains at least a pair of linear parts 23a and a connecting part 23b which connects this pair of linear parts 23a. Inner diameter of the connecting part 23b is larger than the inner diameter of the linear part 23a.COPYRIGHT: (C)2012,JPO&INPIT【課題】給水孔毎の給水量のばらつきを抑制する潅水チューブを提供する。【解決手段】潅水チューブは、液体搬送路11を有する主管10と、主管10の外周に設けられ、液体搬送路11との間に設けられた連通孔21と、外方へ向かう給水孔22と、連通孔21と給水孔22との間に延びる給水路23を有する支管20と、を備えている。給水路23は、少なくとも一対の線状部23aと、この一対の線状部23aを接続する接続部23bとを含む。接続部23bの内径は、線状部23aの内径より大きい。【選択図】図1
