Abstract
A seal member adapted to be mounted between a cylinder head cover and an ignition plug tube comprises a mount portion interposed radially movably between an upper surface of an annular stepped portion formed around an opening of the cylinder head cover for insertion of the ignition plug tube and a baffle plate. A first seal portion and a second seal portion project radially outward and inward, respectively, from the mount portion to be brought into contact with a peripheral surface of the annular stepped portion and the ignition plug tube, respectively. The second seal portion can be elastically deformed following relative radial movements between the mount portion and the ignition plug tube.
