RADIATOR STRUCTURE

PROBLEM TO BE SOLVED: To obtain a radiator structure which achieves improvement of water filling capability and reduction of the number of components around a radiator.SOLUTION: A radiator structure 10 has: an air bleeding pipeline 30 having a first pipeline 32 connected to a passage pipeline 22, which forms a coolant passage, at one end part, and a second pipeline 34 connected to a radiator 14 at one end part and separably connected to the other end part of the first pipeline 32 at the other end part, the air bleeding pipeline 30 used to remove air in the passage pipeline 22; and a rotation part 40 which is provided in a middle part of the second pipeline 34 so that the other end part of the second pipeline 34 is selectively in a connection posture, in which the other end part of the second pipeline 34 is connected to the other end part of the first pipeline 32, and a water filling posture in which the other end part of the second pipeline 34 is separated from the other end part of the first pipeline 32 to orient an opening to the vehicle body upper side.SELECTED DRAWING: Figure 1 【課題】注水性の向上とラジエータ周りの部品点数の低減を両立できるラジエータ構造を得る。【解決手段】冷却水の流路を構成する流路配管２２に一端部が接続された第１配管３２と、一端部がラジエータ１４に接続され、他端部が第１配管３２の他端部と分離可能に接続された第２配管３４と、を有し、流路配管２２内のエアを抜くためのエア抜き配管３０と、第２配管３４の他端部が、第１配管３２の他端部と接続する接続姿勢と、第１配管３２の他端部から分離して開口を車体上方側へ向ける注水姿勢と、を選択的に取れるように、第２配管３４の中途部に設けられた回動部４０と、を備えたラジエータ構造１０とする。【選択図】図１
