タンクに係るものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a fuel tank which is made of synthetic resin and is integrally formed with a fuel tank body and a fuel supply pipe protruding from the body by blow molding or the like. An expansion cavity is formed in the fuel tank body so as to be higher than the protrusion of the fuel supply pipe, and a breather tube with an inlet at one end opened in the cavity is bent lower than the inlet to prevent backflow of fuel. This invention relates to a synthetic resin fuel tank which is fixed so that the discharge port at the other end can be passed through a fuel supply pipe without clogging the pipe.

解決することを問題点としているものである。(Problems to be Solved by the Invention) In the conventional fuel tank illustrated in FIG. must be bent downward (1) at the base C-, of the refueling pipe C. However, when refueling, the fuel flows into the suction port cl.
, fuel flows in from the suction port (1) and accumulates at the bend d-, blocking W2, and the function of the breather tube d is lost when re-injecting. This is not fatal, and due to the compressive force of the air generated in the expansion cavity during refueling, the fuel accumulated in the bend Cl returns from the outlet d-2 into the refueling pipe C and is filled with refueling fuel. However, bending d
, it is ideal to exclude the part . The present invention provides such bending d
The problem is to solve the problem in such a way that it is not necessary to form -3 in the breather tube d.

燃料滞留の問題点を解決できる。(Means for Solving the Problems) As described in the previous section, the present invention stores the fuel in the tank body a between the suction port CL of the breather tube d and the discharge port d-2, and thereby The purpose is to eliminate the downward bend d, which would cause the breather tube to lose its function.The suction port at -i is opened into the expansion space, and the discharge port at the other end is set higher than the suction port at +'+7f. The breather tube that opens into the fuel supply pipe at the position is higher than the communication part of the fuel supply pipe with the fuel tank body, and is fixed by passing it through the holding part that is integrally connected and molded between the fuel tank body and the fuel supply pipe. According to this configuration, the breather tube can be fixed at a higher position than the base of the fuel supply pipe, so that it passes straight through the interior of the fuel supply pipe through the expansion space. This reduces the number of man-hours required to create bends in the breather tube, and also solves the problem of fuel retention.

。(Operations and Effects of the Present Invention) As clarified from the above explanation, the present invention has the suction port (8) at one end opened into the expansion space (2), and the discharge port (11) at the other end opened into the expansion space (2). A preserver chave (
7) is made higher than the connection 1ff1 part of the fuel supply pipe (4) with the fuel tank body (1), and is integrally connected and molded between the fuel tank body (1) and the fuel supply pipe (4). (6)
The structure is such that the breather tube (7) is fixed by passing it inside, without having to bend it downward like in the past.
Since the straight #1 section between the suction port (8) and the discharge port (11) can be fixed by passing it through the holding portion (6), there is no need to block the tube cavity with fuel as in the conventional case. This has the effect of easily resolving one interstitial point in the tank.
