The intake device (1) for an engine includes a carburetor section (2) and an air cleaner section (4). The carburetor section (2) includes a body (5) having an intake passage (6) which has an opening (6a) communicating with the air cleaner section (4) and a choke valve (8) being a butterfly valve having a plate-like valve body (8b). The air cleaner section (4) includes an air filter (12), an air-flow chamber (14) provided between the air filter (12) and the intake passage (6), and a reverse-flow restriction surface (18b) provided within the air-flow chamber (14). The air cleaner section (4) further includes a plate-like partition (24) extending from a location near an air-cleaner side periphery (8c) of the valve body (8b) of the choke valve (8) in the full-open position to a location near the reverse-flow restriction surface (18b) so as to continue the periphery (8c). |
