Summary:PROBLEM TO BE SOLVED: To provide an engine-driven generator which is easy to assemble and has an improved generator efficiency. SOLUTION: A rear cover 4 is connected to a front cover fixed to an engine with a bolt. The stator core 5 of a stator 6 is held between the front cover and the rear cover 4. A bottomed fitting hole 27 is formed in the surface of the stator core 5 which faces the rear cover 4. A collar through-hole 28 is formed in the rear cover 4 so as to face the fitting hole 27. An anchor collar 29 made of insulating material is inserted into the through-hole 28 of the rear cover 4 and the bottomed fitting hole 27 of the stator core 5. The anchor collar 29 has a brim 29a which presses the rear cover 4 on its base part and the tip part of the anchor collar 29 is divided into a plurality of division pieces 29b. While the rear cover 4 is pressed by the brim 29a of the anchor collar 29, the division pieces 29b of the anchor collar 29 are expanded by a screw 30 which is screwed into the guide hole of the axis of the anchor collar 29 to fix the anchor collar 29 to the stator core 5.
