Abstract
An extension piece portion is provided at a lower end portion of a screen plate so as to extend from the lower end portion, beyond a gas-passing through hole, to an oil pocket portion. An oil guide portion is provided at respective gas-hitting-side face portions of the screen plate and the extension piece portion so as to guide oil trapped at the above-described face portions into the oil pocket portion. Accordingly, it can be prevented that part of the oil in the middle of dropping down into the oil pocket portion from the screen plate is carried away by the gas flow passing through the gas-passing through hole, so that the efficiency of oil trap can be improved.
