A motor device and a method for producing same are provided. A connector storage unit () and a substrate storage unit () which are provided in a gear case () open in a direction (axial direction of output shaft) which intersects the axial direction of an armature shaft. As a result, when assembling a motor device (), it is possible to store a connector member () and a control substrate () in the connector storage unit () and the substrate storage unit (), which have comparatively large openings, by insertion therein from the same direction.

Method for producing motor device

A wide sectionwhich contacts a connector member and positions the connector member relative to a connector housing part is provided in a section where a first securing partof a cover memberis provided and is configured so as to be wider than the other parts of the section where the first securing partof the cover memberis provided; hence, it is possible to use the wide sectionin the pressing section (pressing point OP) of an extrusion pin. As a result, it is possible to suppress distortion of the cover memberand to sufficiently smooth the welded section (first securing part) of the cover membereven when the shape of the cover memberis complicated.

Motor device and method for producing same

A motor device is provided. A grommet member () is equipped with a pair of motor-side lip seals () which elastically deform in the insertion direction of an external connector (CN) into a connector member (), and are adhered to a connector cover part () (contact surface) of the cover member (); hence, it is possible to configure in a manner such that the mounting direction of the grommet member () onto a gear case (), and the adhesion direction of the pair of motor-side lip seals () to the cover member (), or in other words, the direction in which sealing properties increase, are the same direction.

Motor device having a grommet member

According to the present invention, a coil is continuously wound in a single pass around each of a series of teeth, and connected to each segment.
