Abstract
In order to provide a filter structure for a
canister in which dust or the like in air is prevented
from sticking to the filter and being distributed over
the entire surface thereof, and accordingly, the filter
can hardly clogging so as to prevent lowering of the
purge volume of a canister due to an increase in
ventilation resistance, the dust filter 8 is formed in
a crescent-like shape, having, at a substantially
center thereof, a pipe hole 8a fitted on a pipe
extended to a filter chamber le, the filter chamber le
accommodating the dust filter 8 is formed in a
crescent-like shape substantially identical with that
of the dust filter 8 and the atmospheric port 1f is
communicated with the bottom side of the dust filter 8,
and accordingly, the atmospheric air flows by a large
volume around the pipe 7a so that the dust or the like
is likely to be accumulated around the pipe 7a, but the
opposite ends becoming narrow outward so that the flow
rate of the atmospheric air is become less. As a
result, the dust or the like can hardly be accumulated
so as to prevent the ventilation resistance of the dust
filter 8 from increasing, thereby preventing leakage of
evaporation fuel into the atmosphere.
Further, in a canister, in order to aim at
restraining the ventilation resistance of the filter
from being increased by dust sucked with air through
the atmospheric port, and at enhancing the mounting
ability of the filter for restraining suction of the
dust, the atmospheric port 33 is formed in the upper
portion of a canister casing 31, dust sucked through
the atmospheric port 33 being caused to stick to the
lower surface of a dust preventing filter 34 while the
sticking dust is allowed to be dropped by vibration.
Further, the dust preventing filter 34 is held by a
filter holding member 35, and is then fitted in a
filter mounting chamber 39 defined in the canister
casing 31. Thereafter, an adsorbent side filter 36 is
secured. A temporary holding device A for temporarily
holding the filter holding member is provided in
the filter holding member 35 and the filter mounting
chamber 39.
