1. A fuel tank connector attached to a fuel tank for connecting a ventilation flow path of the fuel tank connector to the fuel tank, comprising: an upper chamber including a first communication portion relative to the ventilation flow path;a lower chamber including a second communication portion relative to the fuel tank;a bowl-shaped portion situated between the upper chamber and the lower chamber to separate the upper chamber and the lower chamber, the bowl-shaped portion narrowing downward to a bottom portion at a center of the bowl-shaped portion and having a third communication portion at the bottom portion, anda cover body disposed directly above the third communication portion, and having a lateral size smaller than that of the bowl-shaped portion, the cover body including leg portions attached to the bowl-shaped portion, a closed top portion covering the third communication portion, and a side portion partially closing a periphery of the third communication portion with a ventilation interval between the side portion and the third communication portion so that a fluid from the lower chamber hits the cover body and flows to the first communication portion through the ventilation interval. 2. A fuel tank connector according to claim 1, wherein the ventilation interval between the side portion of the cover body and the third communication portion narrows on a side of the first communication portion, and widens on a side away from the side of the first communication portion. 3. A fuel tank connector according to claim 2, wherein the bowl-shaped portion has a plurality of grooves radially upwardly extending from the center of the bowl-shaped portion, the center forming the third communication portion, and a width of each of the plurality of grooves widens from the center of the bowl-shaped portion to an outer end of the bowl-shaped portion.
