Claims

[Scope of utility model registration request]

Two electrodes are integrally attached via an insulator, and the ignition gap formed by these two electrodes is arranged offset from the center of rotation to form a plug body, and the plug body is fixedly attached to the engine. An ignition device characterized in that a plug body is configured to be freely rotatable with respect to a plug mounting member other than at a fixed mounting position, and a position specifying means for specifying the position of an ignition gap is provided.
