Abstract:
A spark plug for an internal combustion engine is provided which has a center electrode and a ground electrode. The ground electrode includes an upright portion extending in a lengthwise direction of the spark plug and an extension bent from the upright portion in a radial direction of the spark plug. The extension has a slant surface which is shaped to be inclined away from the center electrode downstream in a flow of air-fuel mixture within a combustion chamber when the spark plug is mounted in the engine. This results in an increase in in distance by which a starting point on the ground electrode where a spark is created is moved on the slant surface, thereby increasing a length of time the spark is moved downstream and then blown out to increase the probability of successful ignition of the air-fuel mixture.

Claim (Index 3):
A spark plug as set forth in  claim 1 , wherein when viewed in the extension lengthwise direction, a center of the inner extension surface in the lateral direction is offset to the Y 2  side from a center of a front end surface of the center electrode in the lateral direction.
