PROBLEM TO BE SOLVED: To provide a dynamo-electric machine for an internal combustion engine, facilitating assembly operation for an internal combustion engine.SOLUTION: A dynamo-electric machine 10 for an internal combustion engine includes a rotor 21 and a stator 31. The dynamo-electric machine 10 for an internal combustion engine includes a sensor unit 41. The sensor unit 41 has a rotational-position sensor 43 located between magnetic poles. The rotational-position sensor 43 detects the rotational position of the rotor 21 by detecting the magnetic flux from permanent magnets 23 on the rotor 21. The sensor unit 41 is fixed to the stator 31 via an affixing bolt 44 in a fastening section 54. The rotational-position sensor 43 protrudes from the sensor unit 41 and is accommodated inside a cover 53 located between the magnetic poles. The cover 53 contacts the stator so as to define the position of the rotational-position sensor 43 in an axial direction. The sensor unit 41 has a leg part 61. The leg part 61 is deformable in an axial direction by being pressed against a body 13. |
