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.
Claims9
A seal member mounted between a cylinder head cover and an ignition plug tube, comprising:
- a mount portion formed to be at least partially smaller in diameter than an inner diameter of a peripheral surface of an annular stepped portion formed around an opening of the cylinder head cover for insertion of the ignition plug tube, the mount portion being interposed between an upper surface of the annular stepped portion and a baffle plate fused to an underside of the cylinder head cover to be radially movable;
- a first annular seal portion projecting radially outward from the mount portion contacting with the peripheral surface of the annular stepped portion;
- and
- a second annular seal portion projecting radially inward from the mount portion contacting with a peripheral surface of the ignition plug tube to be elastically deformable following relative radial movements between the mount portion and the ignition plug tube.
