Electric power steering device

1. An electric power steering device, comprising:

a motor; and

a control device,

wherein the motor includes a case having a cylindrical shape which is opened at one end portion,

wherein the control device includes:

a control device main body;

a connector connected to the control device main body; and

a housing having a cylindrical shape which is opened at one end portion and closed at another end portion,

wherein the housing houses the control device main body,

wherein the case and the housing are coupled to each other in a state in which an outer peripheral end portion at the one end portion of the case and an outer peripheral end portion at the one end portion of the housing face each other,

wherein a first sealing material is disposed between the outer peripheral end portion of the case and the outer peripheral end portion of the housing,

wherein the connector is disposed between the outer peripheral end portion of the case and the outer peripheral end portion of the housing,

wherein a second sealing material is disposed between the housing and at least one surface facing the housing among a plurality of surfaces which form an outer periphery of the connector, and

wherein a part of the first sealing material disposed between the outer peripheral end portion of the case and the outer peripheral end portion of the housing and a part of the second sealing material disposed between the housing and the surface of the connector adhere to each other.

2. The electric power steering device according to claim 1 ,

wherein the housing includes a connector mounting portion, which is formed on the outer peripheral end portion of the housing, and is configured to receive the connector disposed thereon,

wherein the connector mounting portion includes:

a cutout portion formed so as to extend from the outer peripheral end portion toward another end portion of the housing; and

a connector mounting base, which is formed at a bottom portion of the cutout portion, and protrudes toward a radially outer side of the housing,

wherein the connector is disposed on the connector mounting base in a state in which a part of the connector protrudes to an outside of the housing from the cutout portion, and

wherein the second sealing material is disposed between the connector mounting base and the one surface among the plurality of surfaces which form the outer periphery of the connector, and between another two surfaces which form the outer periphery of the connector and both side surfaces of the cutout portion.

3. The electric power steering device according to claim 1 , wherein a material of the first sealing material is different from a material of the second sealing material.

4. The electric power steering device according to claim 1 ,

wherein at least one of the outer peripheral end portion of the housing, the outer peripheral end portion of the case, and the outer periphery of the connector includes:

a recessed portion which is open toward an intersecting region between a region in which, among the outer peripheral end portion of the housing, the outer peripheral end portion of the case, and the outer periphery of the connector, a set of any two is sealed, and a region in which another set of any two is sealed intersect each other.

5. The electric power steering device according to claim 4 , wherein, in the intersecting region between the region in which the outer peripheral end portion of the housing and the outer periphery of the connector are sealed and the region in which the outer peripheral end portion of the housing and the outer peripheral end portion of the case are sealed, a distance between the outer peripheral end portion of the housing and the outer peripheral end portion of the case is larger than a distance between the outer periphery of the connector and the outer peripheral end portion of the case.

6. The electric power steering device according to claim 4 ,

wherein, in the intersecting region between the region in which the outer peripheral end portion of the housing and the outer periphery of the connector are sealed and the region in which the outer peripheral end portion of the housing and the outer peripheral end portion of the case are sealed,

a distance between the outer periphery of the connector and the outer peripheral end portion of the case is larger than a distance between the outer peripheral end portion of the housing and the outer peripheral end portion of the case.

7. The electric power steering device according to claim 2 , wherein both side surfaces of the cutout portion include inclined portions which are inclined so as to extend from the outer peripheral end portion of the housing toward the connector mounting base.
