A rotary electric machine according to the present invention includes: a rotor; a stator that includes: an annular stator core that is disposed so as to surround the rotor; and a plurality of concentrated winding coils that are wound onto the stator core; a holder that includes an annular holder portion in which a groove is formed on one surface so as to extend circumferentially, the holder being disposed on a first axial end of the stator such that a second surface of the holder portion is oriented toward the stator; and a plurality of connecting terminals that are held by the holder, coil terminals of the plurality of concentrated winding coils each extending outward from the concentrated winding coils, being led around circumferentially through the groove, and being connected to connecting terminals that are subject to connection therewith.

Rotary electrical machine

The invention relates to a waterproof electronic control device such that a connector unit is inserted into at least one wall face of a case, a control substrate is incorporated in a housing chamber formed of the case and connector unit, an aperture portion and an upper face of the connector unit are covered with a cover, and a waterproofing member is disposed on a contact surface of each of the case, connector unit, and cover. A structure is such that a first inclined portion is provided in a side wall of one portion of the case, a regulating wall is provided in a direction opposing an inclined face of the first inclined portion, a second inclined portion of the connector unit is provided in a position opposing the first inclined portion and comes into contact with an inner face of the regulating wall when inserted into the case, and the first inclined portion and the second inclined portion come into contact at a final insertion stage of the second inclined portion.

Waterproof electronic control device

A peripheral wall includes a first peripheral wall edge portion and a second peripheral wall edge portion, which are disposed on a case member bottom surface so as to be distant from each other. A connector member main unit is disposed in a space between the first and second peripheral wall edge portions. A peripheral wall groove, which is open toward the connector member main unit, is disposed in each of the first and second peripheral wall edge portions. A bottom surface of the peripheral wall groove is inclined with respect to the case member bottom surface. A base plate groove is disposed on the bottom surface of the case member. A seal material is filled into the space formed between each of an inner surface of the peripheral wall groove and an inner surface of the base plate groove, and the connector member.
