1. An oil separator unit configured to separate an oil mist contained in a blowby gas generated in an internal combustion engine, comprising:

  • an upstream member disposed on an upstream side in a flow direction of the blowby gas and having an opening through which the blowby gas passes;

    a downstream member disposed on a downstream side in the flow direction of the blowby gas and having a hit portion hit by the blowby gas; and

    a porous member including a first surface facing the upstream member and a second surface facing the downstream member and formed in a substantially rectangular shape with a predetermined thickness so as to trap the oil mist contained in the blowby gas that has passed through the opening, whereinthe upstream member includes an upstream surface facing the first surface and a spacer projected from the upstream surface and provided in contact with the first surface to support the first surface,the downstream member includes a downstream surface facing the second surface and a rib projected from the downstream surface and provided in contact with the second surface to support the second surface,the spacer is extended along a first direction and the rib is extended along a second direction substantially perpendicular to the first direction,the spacer includes a support surface configured to support the first surface of the porous member and a projecting portion projected from the support surface of the spacer, andthe rib includes a support surface configured to support the second surface of the porous member and a projecting portion projected from the support surface of the rib.
