摘要： A filler neck is connected to a connection pipe attached to a pouring port of a header tank of a radiator. A radiator cap having a pressure valve and an overflow pipe connected to a reservoir are attached to the filler neck. The filler neck has a cylindrical portion which includes an annular pressure-valve sealing portion making contact with the pressure valve, an opening formed inside an inner diameter of the pressure-valve sealing portion to communicate with the connection pipe and an opening peripheral portion formed along a periphery of the opening. The opening peripheral portion is disposed above a lower end of the overflow pipe. The filler neck is formed by pressing a metal plate. Therefore, the filler neck made of metal is readily formed into a shape substantially equal to that of a resin filler neck.
