Abstract:
1. A canister vent valve mounting structure comprising: a first vent valve connecting section adapted to be coupled to a canister configured to adsorb fuel vapors produced inside a fuel tank, the first vent valve connecting section including an insertion hole; a second vent valve connecting section adapted to be coupled to a canister vent valve configured to introduce outside air into the canister, the second vent valve connecting section including a connecting pipe part that fits into the insertion hole; and a sealing member being configured to seal a space between the connecting pipe part and the insertion hole when the first and second vent valve connecting sections are coupled together, one of the first and second vent valve connecting sections including a plurality of mating projections that are circumferentially spaced apart near the tip thereof, the other of the first and second vent valve connecting sections including a protrusion with a plurality of mating notches into which the mating projections are inserted, the mating projections and the mating notches being configured to mate with each other such that the protrusion engages the projections upon relative rotational movement of the first and second vent valve connecting sections, the first and second vent valve connecting sections including a rotation regulating structure configured to selectively retain the first and second vent valve connecting sections in at least two different angular positions relative to each other.
