Abstract: A circuit board including a through-hole into which a press-fit terminal portion is inserted in a depth direction; an inner wall land provided on an inner wall of the through-hole; and a plurality of inner layer lands which are provided in an inner layer of the circuit board, are planes substantially parallel to a mounting surface of the circuit board, and are in contact with the inner wall land. The inner wall land has a first region that is in contact with the press-fit terminal portion and a second region that is not in contact with the press-fit terminal portion. Among the plurality of inner layer lands, a first inner layer land, which is an inner layer land disposed on an identical surface with the first region of the inner wall land, is wider than a second inner layer land which is an inner layer land disposed on an identical surface with the second region of the inner wall land.

Abstract: An object of the present invention is to firmly fix a magnet at a predetermined position of a magnet insertion portion. A rotor for a rotary electric machine includes: a rotary shaft; at least one magnet; a rotor core having at least one magnet housing inside which the at least one magnet is attached; and at least one fixing member disposed inside the at least one magnet housing to fix the at least one magnet, wherein the at least one fixing member includes: a first fixing portion that is in contact with a side surface of the at least one magnet in a radial direction of the rotary shaft or in contact with a side surface of the at least one magnet in a circumferential direction of the rotary shaft; and a second fixing portion that is in contact with an end face of the at least one magnet in an axial direction of the rotary shaft. The first fixing portion and the second fixing portion are connected to each other at an angle smaller than 90 degrees, and the at least one fixing member is inserted, together with the at least one magnet, in the at least one magnet housing and presses the at least one magnet against an inner wall of the at least one magnet housing due to an increase in the angle between the first fixing portion and the second fixing portion.
