Abstract

In an ignition device, a proportion of a yoke end width defined as a distance from one end to another end of an end portion of each of a pair of yokes in the circumferential direction to a magnet width defined as a distance from one end to another end of a permanent magnet disposed on the outer circumferential surface of a flywheel, in the circumferential direction is in a range of 60% to 100%. Moreover, a proportion of the magnet width to a yoke interval between the pair of yokes is in a range of 95% to 100%.
