摘要： PROBLEM TO BE SOLVED: To simplify construction while maintaining a convenience in inserting a pipe into a resin tube. SOLUTION: When the pipe 20 is inserted into the resin tube 10 to link a fluid passage, an insertion portion 22 of the pipe 20 is inserted into a joint portion 12 of the resin tube 10. A joint part 14 and a straight tube part 13 of the joint portion 12 are in the condition of the insertion portion 22 being inserted with no gap to the inner peripheral face or are expanded by the insertion portion 22. In the joint part 14, an engaging boss 24 of the insertion portion 22 is located inside its crest portion 14a. The engaging boss 24 annularly uprising on the outer peripheral side of the pipe has contact with a valley portion 14b extending from the crest portion 14a of the joint part 14. It is reliably functioned to prevent the come-off of the pipe because the backward movement (come-off) of the pipe 20 is interrupted by the valley portion 14b. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a fuel tank device capable of adding fuel, and preventing fuel from returning to or flowing out of an fuel-supply opening at the time of stopping supply of the fuel with a simple structure.
SOLUTION: This fuel tank device has an fuel supplying mechanism 20 supplying fuel to a fuel tank 10, and a fuel blocking mechanism for blocking communication between the fuel tank 10 and the outside. The fuel supplying mechanism 20 has a check valve 30 opening and closing an output port 33b of a fuel supplying tube 21. The fuel blocking mechanism closes a first connection path 64a connecting inside of the fuel tank 10 and the outside by raising a float 67 up to a first liquid level FL1 of the fuel. Thereby heightens a tank inner pressure. The check valve 30 closes an output port 33b by a valve element 40 when reaching to a second liquid level FL2 higher than the first liquid level FL1. Furthermore, the fuel blocking mechanism closes a second connection path 71e when reaching to a third liquid level FL3 higher than the second liquid level FL2.
