の防塵構造。 A power generator is equipped with a power generation section that includes a rotor that is integrally rotatably connected to a crankshaft that protrudes from the engine, and a stator that is arranged to face the outer peripheral surface of the rotor. A crank angle sensor section consisting of a rotor disk held in a sandwich manner by a joint provided at the tip of the shaft and the rotor, and a sensor head that reads a plurality of slits formed in the rotor disk is connected to the engine rather than the power generation section. An inward flange portion formed at the distal end side of the case body covering the sensor portion and an outward flange portion formed at the proximal end portion of the rotor overlap, The uneven parts formed on the opposing surfaces of both overlapping flanges are
A dust-proof structure for a generator integrated with a crank angle sensor, characterized in that a labyrinth is formed by loosely fitting each other in an interlocking manner.
