Abstract
A wide section 71d which contacts a connector member and positions the connector member relative to a connector housing part is provided in a section where a first securing part 71b of a cover member 70 is provided and is configured so as to be wider than the other parts of the section where the first securing part 71b of the cover member 70 is provided; hence, it is possible to use the wide section 71d in the pressing section (pressing point OP) of an extrusion pin. As a result, it is possible to suppress distortion of the cover member 70 and to sufficiently smooth the welded section (first securing part 71b) of the cover member 70 even when the shape of the cover member 70 is complicated.
Claims6
A motor device provided with an output shaft configured to be rotated by a rotation shaft, the motor device comprising:
- a housing including an opening that is opened in an axial direction of the output shaft;
- a connector storage unit provided in the housing and configured to store a connector member to which an external connector is connected;
- a cover configured to block the opening;
- an exposure hole provided in the cover and configured to expose a connector connecting unit of the connector member to which the external connector is connected to outside;
- a first securing unit provided in the periphery of the exposure hole in the cover and secured to the housing;
- a second securing unit provided in a portion other than the periphery of the exposure hole in the cover and secured to the housing;
- and
- a positioning unit provided at a portion of the cover at which the first securing unit is provided, having a wider width than a width of a portion other than the portion of the cover in which the first securing unit is provided, and configured to abut on the connector member and position the connector member with respect to the connector storage unit.
A method for producing a motor device provided with an output shaft that is rotated by a rotation shaft, the motor device comprising
- a housing including an opening that is opened in an axial direction of the output shaft,
- a connector storage unit provided in the housing and configured to store a connector member to which an external connector is connected,
- a cover configured to block the opening,
- an exposure hole provided in the cover and configured to expose a connector connecting unit of the connector member to which the external connector is connected to outside,
- a first securing unit provided in the periphery of the exposure hole in the cover and secured to the housing,
- a second securing unit provided in a portion other than the periphery of the exposure hole in the cover and secured to the housing, and
- a positioning unit provided in a portion of the cover in which the first securing unit is provided, having a wider width than a width of a portion other than the portion of the cover in which the first securing unit is provided, and configured to abut on the connector member and position the connector member with respect to the connector storage unit,
- wherein the cover is formed through
- a first process in which a pair of molds are caused to abut on each other to form a cavity for forming the cover inside the pair of molds,
- a second process in which a molten resin supply device is operated to cause a molten resin to flow into the cavity, and
- a third process in which a pressing pin provided in at least one of the pair of molds is operated to press the positioning unit and release the cover.
