1. A rotating electric machine system including a rotating electric machine and a rotating electric machine housing configured to rotatably support a rotating shaft of the rotating electric machine,
wherein the rotating shaft includes a first end part and a second end part, and a first bearing is disposed between the rotating electric machine housing and the first end part, and a second bearing is disposed between the rotating electric machine housing and the second end part, whereby the rotating shaft is rotatably supported by the rotating electric machine housing via the first bearing and the second bearing; and
the first end part includes a projecting distal end configured to pass through the first bearing;
the rotating electric machine system comprising:
a rotational parameter detector disposed at the projecting distal end via a retaining member, and configured to detect a rotational parameter of the rotating shaft;
electric terminal portions electrically connected to the rotating electric machine; and
a terminal casing in which the electric terminal portions are accommodated,
wherein,
the rotating electric machine housing comprises
a hollow main housing in which both ends thereof are open ends,
a first sub-housing configured to close one of the open ends of the main housing, and
a second sub-housing configured to close another of the open ends of the main housing,
the first sub-housing is exposed from the open ends of the main housing and includes an exposed portion an outer diameter of which is smaller than an outer diameter of the main housing wherein a step portion is formed between the exposed portion and the main housing,
the terminal casing is supported by an outer circumferential surface of the exposed portion, and an end portion of the terminal casing closer to the main housing is located at the step portion,
the projecting distal end projects out from the main housing and is located in a hollow interior part of the exposed portion of the first sub-housing, and
in the rotating electric machine system, the electric terminal portions and the rotational parameter detector are arranged in parallel when viewed from a side along a first direction, which is an extending direction of the rotating shaft.
