  By the way, in recent years, due to the mounting space in the vehicle, it is desired that the motor as described above suppress the projection area of the motor as small as possible when viewed from the direction of the rotation axis of the rotor. In particular, in an electric column device that adjusts the tilt position and telescopic position of the steering wheel using the driving force of the motor according to the physique and driving posture of the driver, when the motor is installed in the electric column device, the electric column device It is significantly desired to keep the column axis projection area of the apparatus as small as possible.

  In order to reduce the projected area of the motor viewed from the rotation axis direction of the rotor, for example, it is conceivable to reduce the size of the yoke housing in the radial direction. However, in order to ensure the output characteristics of the motor, it is not preferable to downsize the yoke housing in the radial direction. Further, for example, it is conceivable to downsize the flange portion in the radial direction. However, considering the connection strength between the yoke housing and the housing case, there is a limit to downsizing the flange portion in the radial direction.

  Therefore, in order to keep the projection area of the motor (for example, the motor assembled in the electric column device) viewed from the direction of the rotation axis of the rotor small, a power feeding unit for feeding power to the motor is provided on the outer peripheral surface of the yoke housing. It has been a problem to suppress the amount protruding outward in the radial direction.

  In the motor described in Patent Document 1, a connector portion that is a power feeding portion protrudes to one side in the longitudinal direction of the yoke housing. Therefore, when the motor is viewed from the direction of the rotation axis of the rotor, the projected area of the motor is enlarged by the connector portion around the yoke housing.

  Further, in the motor described in Patent Document 2, the amount by which the power feeding portion protrudes radially outward from the outer peripheral surface of the yoke housing is suppressed to be smaller than that of the motor described in Patent Document 1, and the rotor The projected area of the motor as seen from the direction of the rotation axis is small. However, since the number of parts increases or the assembly becomes complicated, the manufacturing cost increases.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a motor capable of suppressing the projection area viewed from the direction of the rotation axis of the rotor to be small and an electric column device including the motor. It is to provide.

  A motor that solves the above problems includes a rotor, and a cylinder in which the rotor is arranged inside and has a flat shape having a longitudinal direction and a short direction when viewed from the rotation axis direction of the rotor, and one end is closed. And a yoke housing having a flange portion extending radially outward from the opening of the cylindrical portion and provided with a fastening hole, a housing case for housing a worm that rotates integrally with the rotor, and the yoke A plurality of connector terminals including a brush holding portion that is disposed between a housing and the housing case and holds a power supply brush for supplying power to the rotor, and a power supply terminal electrically connected to the power supply brush. A brush holder having a connector portion provided integrally with the brush holding portion, and a fastening member that is inserted through the fastening hole and connects the yoke housing and the housing case. And the fastening holes are respectively provided at one end side and the other end side in the longitudinal direction across the rotation axis of the flange portion, and the connector portion is viewed from the direction of the rotation axis. The flange portion is arranged in the longitudinal direction with the fastening hole provided on one end side in the longitudinal direction, and does not protrude to the outer peripheral side from the flange portion in the longitudinal direction. , Along the short direction.

  According to this configuration, the connector portion is aligned with the fastening hole provided on one end side in the longitudinal direction of the tubular portion in the flange portion and the short direction of the tubular portion as seen from the rotational axis direction of the rotor, It does not protrude outward from the flange portion in the longitudinal direction of the tubular portion. Furthermore, the several connector terminal hold | maintained at a connector part is located in a line along the transversal direction of a cylindrical part. Accordingly, the connector portion, which is a power feeding portion for feeding power to the motor, is suppressed from the outer peripheral surface of the yoke housing while suppressing the motor from becoming thick in the thickness direction of the yoke housing (that is, the short direction of the cylindrical portion). The amount protruding in the radial direction can be suppressed. As a result, the projected area of the motor viewed from the direction of the rotation axis of the rotor can be kept small.

  In the motor, the fastening hole provided on one end side in the longitudinal direction of the flange portion is more than the first center line extending in the lateral direction through the rotational axis when viewed from the rotational axis direction. Provided in a first range on one side in the longitudinal direction and on one side in the lateral direction with respect to a second center line extending in the longitudinal direction through the rotation axis, and in the longitudinal direction of the flange portion The fastening hole provided on the other end side is the other side of the longitudinal direction from the first center line and the short side direction from the second center line when viewed from the rotational axis direction. It is preferable to be provided in the second range on the other side.

  According to this configuration, the fastening hole provided on one end side in the longitudinal direction of the tubular portion in the flange portion is located at a position shifted from the second center line, that is, in the flange portion when viewed from the rotation axis direction of the rotor. It is provided at a position shifted from the central portion of the tubular portion in the short direction. Therefore, it is easy to secure a range in which the connector portion is provided while suppressing the amount of the connector portion protruding in the radial direction from the outer peripheral surface of the yoke housing. Further, the second range is located on the opposite side of the first range with respect to the rotation axis of the rotor. Accordingly, the yoke housing and the housing case are connected by inserting the fastening member through the fastening hole provided in the first range and the fastening hole provided in the second range and connecting the yoke housing and the housing case. And can be stably fixed.

  In the motor, the cylindrical portion has a cross-sectional shape in a direction perpendicular to the rotation axis between a pair of flat portions that are parallel to each other on both sides in the radial direction of the rotor, and between the pair of flat portions, respectively. It is preferable that the connecting portion has a flat shape including connecting arc-shaped arc portions, and the connector portion is located on the housing case side with respect to the flange portion.

  According to this configuration, since the connector portion is disposed on the housing case side with respect to the flange portion, the connector portion is located on the outer circumferential side of the flange portion in the longitudinal direction of the cylindrical portion when viewed from the rotation axis direction of the rotor. It becomes easier to secure a space for providing the connector portion so as not to protrude.

  In the motor, the connector portion includes a side wall portion that extends in the rotation axis direction and surrounds the plurality of connector terminals, the end portion in the short direction of the side wall portion, and the connector portion in the rotation axis direction. It is preferable that an engaging portion that engages in the direction of the rotation axis is provided with an external connector that is inserted along.

  According to this configuration, the engaging portion that engages in the rotational axis direction of the external connector and the rotor is provided at the short-side end portion of the cylindrical portion in the side wall portion of the connector portion. Therefore, it is possible to provide the motor with a portion where the external connector and the connector portion engage with each other in the rotation axis direction of the rotor while suppressing the motor from being enlarged in the longitudinal direction of the cylindrical portion. As a result, it is possible to suppress the external connector from dropping from the connector portion while suppressing the motor from being enlarged in the longitudinal direction of the cylindrical portion.

In the motor, it is preferable that the connector portion is housed within the width of the flange portion in the short direction.
According to this configuration, it is possible to further suppress the motor from becoming thicker in the thickness direction of the yoke housing (that is, the short direction of the cylindrical portion), and as a result, the projected area of the motor as viewed from the rotation axis direction of the rotor. Can be kept smaller.

The external connector and the electronic control unit connection connector through a second lead wire are electrically connected to be inserted into the connector portion of the second motor and have the same shape as the first external connector. Electrically connected to the electronic control unit by a bifurcated lead having a second external connector.

  According to this configuration, the first motor and the second motor have a small projection area viewed from the direction of the rotation axis of the rotor, so that it is easy to secure a mounting space on the vehicle, and the electric column device Increase in size can be suppressed.

  The bifurcated lead wire connecting the first and second motors to the electronic control unit has the same shape as the first external connector inserted into the connector portion of the first motor and the first external connector. And a second external connector to be inserted into the connector portion of the second motor. Thus, since the shape of the first external connector and the second external connector is the same, the first motor as a drive source of the electric tilt column apparatus and the drive source of the electric telescopic column apparatus.

Then, the tie rod 17 is moved via the rack and pinion mechanism of the steering gear 15 so that the steering angle of the front wheel 18 can be changed.

  As shown in FIG. 2, the electric column apparatus 10 includes an electric tilt column apparatus 20 that adjusts the tilt position of the steering wheel 12 using the driving force of the motor. A portion of the steering shaft 11 on the rear side of the vehicle body and disposed in the vehicle compartment is included in a steering column 21 (hereinafter referred to as column 21), and is pivotally supported by the steering column. Yes. The steering column 21 is located on the front side of the vehicle body with respect to the steering wheel 12 and is covered with a column cover 22. The electric tilt column device 20 is provided on the steering column 21.

  A column 21 front end (left end in FIG. 2) of the column 21 is pivotally supported by a lower body mounting bracket 24 fixed to the vehicle 23 and extends in the left-right direction of the vehicle 1 (perpendicular to the plane of FIG. 2). The support shaft 25 is pivotally supported with respect to the lower vehicle body mounting bracket 24. Further, the end of the column 21 on the vehicle body rear side (the end on the right side in FIG. 2) is supported by an upper vehicle body mounting bracket 26 fixed to the vehicle body 23 so that the tilt position can be adjusted.

  The column 21 includes a bracket 28 to which a motor 27 serving as a drive source for the electric tilt column apparatus 20 is fixed.

It is elastically deformed to the side. At this time, the elastic deformation of the side wall portion 92 is allowed by opening the slit 95 so that the width in the short direction X2 is widened. When the external connector 110 is inserted into the connector portion 83 until the entire engaging convex portion 112 is disposed at a position overlapping the engaging hole 94 in the short direction X2, the side wall portion 92 returns to the original shape, and the engaging convex portion The portion 112 is disposed in the engagement hole 94. And the external connector side engaging surface 112b and the connector part side engaging surface 94a contact | abut in the rotation axis L1 direction (same as the insertion direction X13). As a result, the engagement convex portion 112 is snap-fit engaged with the engagement hole 94, and the external connector 110 is prevented from coming out of the connector portion 83. Further, when the engaging convex portion 112 is engaged with the engaging convex portion 112 in the rotation axis L1 direction, the stopper protrusion 114 is moved from the insertion direction X13 (rotational axis L1 direction) to the distal end surface (side wall portion 92 of the side wall portion 92). The outer connector 110 is in contact with the distal end surface, and further insertion of the external connector 110 into the connector portion 83 (movement in the insertion direction X13) is prevented.

When the fixed portion 101 is viewed from the direction of the rotation axis L1, the second housing side fastening hole 102b is provided at a position that is substantially diagonal to the first housing side fastening hole 102a across the rotation axis L1. ing.

  The housing case 100 is attached to the yoke 61 so as to sandwich the outer peripheral edge portion (elastic member 87) of the holder main body 82 (see FIG. 9B) of the brush holder 81 between the fixing portion 101 and the flange portion 63. Has been placed. The housing case 100 passes through the first fastening hole 65a and the first screw 103a as a fastening member screwed into the first housing side fastening hole 102a and the second fastening hole 65b. It is connected to the yoke 61 by a second screw 103b as a fastening member screwed into the second housing side fastening hole 102b.

  The housing case 100 also has a worm shaft housing portion 104 that extends from the fixed portion 101 in the direction of the rotation axis L1 in the direction opposite to the yoke 61. When viewed from the direction of the rotation axis L <b> 1, the worm shaft housing portion 104 is within the outer shape range of the fixed portion 101 (that is, within the outer shape range of the yoke 61). The worm shaft accommodating portion 104 has a hollow shape, and accommodates a portion on the distal end side that penetrates the holder main body 82 of the brush holder 81 in the rotating shaft 72 inside. The worm shaft accommodating portion 104 holds a bearing 105 that supports the tip end portion of the rotating shaft 72 therein. A worm 77 provided between the bearing 105 and the bearing 84 in the rotating shaft 72 is accommodated in the worm shaft accommodating portion 104 together with the rotating shaft 72. The worm shaft accommodating portion 104 is provided with a worm exposure port 106 that exposes the worm 77 to the outside. The worm wheel 31 (see FIG. 2) meshes with the worm 77 through the worm exposure port 106.

  In the motor 27 as described above, when current is supplied from the connector terminal 111 of the external connector 110 to the rotor 71 via the connector terminal 93 of the connector portion 83 and the power supply brush 85, the rotor 71 rotates. The rotation of the rotor 71 is transmitted while being decelerated to the worm wheel 31 meshed with the worm 77 that rotates integrally with the rotating shaft 72 of the rotor 71.

  As shown in FIG. 13, the electric column apparatus 10 includes an electronic control unit 120 (hereinafter referred to as an ECU 120) that controls driving of the motor 27 of the electric tilt column apparatus 20 and the motor 48 of the electric telescopic column apparatus 40. Yes. The motor 27 and the motor 48 are electrically connected to the ECU 120 by a bifurcated lead wire 130.

  The ECU 120 has a motor connection connector 121 for electrically connecting the motors 27 and 48. The bifurcated lead wire 130 has an electronic control unit connection connector 131 (hereinafter referred to as an ECU connection connector 131) that is electrically and mechanically connected by being inserted into the motor connection connector portion 121. The bifurcated lead wire 130 has a first external connector 133 that is electrically and mechanically connected to the ECU connection connector 131 via the first lead wire 132 and is inserted into the connector portion 83 of the motor 27. Further, the bifurcated lead wire 130 has a second external connector 135 that is electrically and mechanically connected to the ECU connection connector 131 via the second lead wire 134 and is inserted into the connector portion 83 of the motor 48. In the present embodiment, since the motor 27 and the motor 48 have the same shape, the connector portion 83 of the motor 27 and the connector portion 83 of the motor 48 have the same shape. Therefore, the first external connector 133 and the second external connector 135 have the same shape. That is, the first external connector 133 and the second external connector 135 are both the external connectors 110 described above.

  In this way, the first external connector 133 is inserted into the connector portion 83 of the motor 27, the second external connector 135 is inserted into the connector portion 83 of the motor 48, and the ECU connection connector 131 is used for connecting the motor of the ECU 120. By being connected to the connector part 121, the motors 27 and 48 and the ECU 120 are electrically connected via the bifurcated lead wire 130. The order in which the ECU connection connector 131, the first external connector 133, and the second external connector 135 are inserted into the bifurcated lead wire 130 is not limited.

  As shown in FIG. 14, the motor connecting connector 121 of the ECU 120 is disposed closer to the motor 48 than the motors 27 and 48 disposed at positions separated from each other. Then, by making the length of the second lead wire 134 shorter than the length of the first lead wire 132, the first external connector 133 and the second external connector 133 are connected to the connector portions 83 of the motors 27 and 48. It is possible to prevent erroneous assembly that alternately connects the connectors 135.

  Specifically, as shown in the figure, the length of the first lead wire 132 is set such that the first external connector 133 can be connected to the connector portion 83 of the motor 27. The length of the second lead wire 134 is set such that the second external connector 135 can be connected to the connector portion 83 of the motor 48 and does not reach the connector portion 83 of the motor 27. Thereby, it can prevent connecting the 2nd external connector 135 to the connector part 83 of the motor 27 accidentally. 14, the motor connection connector 121 of the ECU 120 may be disposed near the motor 27 and the length of the first lead wire 132 may be shorter than the length of the second lead wire 134. Similar effects can be obtained.

Next, the operation of this embodiment will be described.
The connector portion 83 is aligned with the first fastening hole 65a provided on one end side of the longitudinal direction X1 in the flange portion 63 and the short direction X2 when viewed from the direction of the rotation axis L1, and from the flange portion 63 in the longitudinal direction X1. Also does not protrude outward. Further, the plurality of connector terminals 93 held by the connector portion 83 are arranged in a line along the short direction X2. Therefore, while suppressing the motor 27 from becoming thick in the thickness direction of the yoke 61 (that is, the short direction X2 of the cylindrical portion 62) (while maintaining the thinness of the motor 27 in the thickness direction of the yoke 61), The amount of the connector 83 protruding in the radial direction from the outer peripheral surface of the yoke 61 can be suppressed.

Next, the effect of this embodiment will be described. In addition, although only the effect about the motor 27 is described below, the same effect is acquired also about the motor 48. FIG.
(1) The connector portion 83 which is a power feeding portion for feeding power to the motor 27 while suppressing the thickness of the motor 27 from increasing in the thickness direction of the yoke 61 (that is, the short direction X2 of the cylindrical portion 62) is The amount protruding in the radial direction from the outer peripheral surface of 61 can be suppressed. As a result, the projected area of the motor 27 viewed from the direction of the rotation axis L1 can be reduced.

  (2) The first fastening hole 65a provided on one end side in the longitudinal direction X1 in the flange portion 63 is a first center line C1 extending in the short direction X2 through the rotational axis L1 when viewed from the rotational axis L1 direction. It is provided in the first range A1 which is on one side in the longitudinal direction X1 and on the one side in the lateral direction X2 with respect to the second center line C2 extending in the longitudinal direction X1 through the rotation axis L1. Therefore, the first fastening hole 65a provided on one end side in the longitudinal direction X1 in the flange portion 63 is short in the flange portion 63 when viewed from the position shifted from the second center line C2, that is, from the direction of the rotation axis L1. It is provided at a position shifted from the center of the direction X2. Therefore, it is easy to secure a range in which the connector portion 83 is provided while suppressing the amount of the connector portion 83 protruding in the radial direction from the outer peripheral surface of the yoke 61.

  Further, the second fastening hole 65b provided on the other end side in the longitudinal direction X1 in the flange portion 63 is the other side in the longitudinal direction X1 with respect to the first center line C1 as viewed from the direction of the rotation axis L1, and The second range A2 is provided on the other side in the lateral direction X2 from the second center line C2. And 2nd range A2 is located in the other side on both sides of rotation axis L1 with respect to 1st range A1. Accordingly, the first screw 103a is inserted into the first fastening hole 65a provided in the first range A1, and the second screw 103b is inserted into the second fastening hole 65b provided in the second range A2. By inserting and connecting the yoke 61 and the housing case 100, the yoke 61 and the housing case 100 can be stably fixed.

  (3) The cylindrical portion 62 has a cross-sectional shape in a direction orthogonal to the rotation axis L1 between the pair of flat portions 62b and the pair of flat portions 62b that are parallel to each other on both sides in the radial direction of the rotor 71. It has a flat shape composed of connecting arc-shaped arc portions 62c. The connector portion 83 is located on the housing case 100 side (the opposite side to the tubular portion 62) with respect to the flange portion 63. Accordingly, since the connector portion 83 is disposed on the housing case 100 side with respect to the flange portion 63, the connector portion 83 does not protrude from the flange portion 63 to the outer peripheral side in the longitudinal direction X1 when viewed from the direction of the rotation axis L1. It becomes easier to secure a space for providing the connector portion 83.

  (4) The connector portion 83 includes a side wall portion 92 that extends in the direction of the rotation axis L1 and surrounds the plurality of connector terminals 93. An engagement hole 94 that engages in the rotation axis L1 direction with an external connector 110 that is inserted into the connector portion 83 along the rotation axis L1 direction is provided at the end of the side wall portion 92 in the short direction X2. As described above, the engagement hole 94 that engages with the external connector 110 in the direction of the rotation axis L <b> 1 is provided at the end of the side wall portion 92 of the connector portion 83 in the short direction X <b> 2. Therefore, the portion where the external connector 110 and the connector portion 83 engage in the direction of the rotation axis L1 (that is, the engagement hole 94 and the engagement protrusion) is suppressed while the motor 27 is prevented from being enlarged in the longitudinal direction X1 on the outer peripheral side. Part 112) can be provided in the motor 27. In other words, when viewed from the direction of the rotation axis L1, the engagement projection 94 that engages with the engagement hole 94 of the connector 83 and the engagement hole 94 of the external connector 110 protrudes more outward than the flange 63 in the longitudinal direction X1. The engagement hole 94 can be easily provided while avoiding this. As a result, it is possible to suppress the external connector 110 from falling off the connector portion 83 while suppressing the motor 27 from being enlarged in the longitudinal direction X1.

  (5) The connector portion 83 has a flat shape in which the longitudinal direction X1 is the thickness direction. And the side wall part 92 has the slit 95 which carries out uneven | corrugated engagement with the misassembly prevention convex part 113 provided in the external connector 110, and the rotation axis L1 direction in the side surface of the thickness direction of the connector part 83. FIG. Therefore, when the external connector 110 is inserted into the side wall portion 92 of the connector portion 83, the external connector 110 is placed in the wrong direction by engaging the misassembly prevention convex portion 113 and the slit 95 in the direction of the rotation axis L1. Insertion into the connector part 83 can be suppressed.

  (6) The slit 95 for allowing elastic deformation of the side wall portion 92 when the engagement convex portion 112 of the external connector 110 and the engagement hole 94 of the connector portion 83 are snap-fit engaged, causes the external connector 110 to be incorrect. It also serves as an engaging part for preventing erroneous assembly for preventing the connector part 83 from being inserted in the orientation. Therefore, the shape of the connector portion 83 is complicated as compared with the case where the connector portion 83 is provided with an engaging portion that engages with the misassembly preventing convex portion 113 in order to prevent misassembly. This can be suppressed.

  (7) The flange portion 63 has a smaller amount of extension in the short direction X2 than the amount of extension in the longitudinal direction X1. Therefore, it is easy to suppress the motor 27 from becoming thick in the thickness direction of the yoke 61 (that is, the short direction X2 of the cylindrical portion 62). Moreover, it is easy to provide the 1st and 2nd fastening holes 65a and 65b provided in the flange part 63 at the one end side and other end side of the longitudinal direction X1.

  (8) The engagement hole 94 that engages with the engagement convex portion 112 of the external connector 110 is an end portion on one side of the side wall portion 92 of the connector portion 83 in the short-side direction X2, and the first fastening hole 65a. It is provided in the adjacent part. Therefore, compared with the case where the engagement hole 94 is provided at the other end portion in the lateral direction X2 on the opposite side of the first fastening hole 65a in the side wall portion 92, the engagement hole 94 and the engagement convex portion 112 are used. The connector portion 83 can be provided with an engagement hole 94 that engages the external connector 110 in the direction of the rotation axis L1 while further suppressing the motor 27 from being enlarged in the longitudinal direction X1.

  (9) The connector portion 83 of the present embodiment is not connected to the circuit board 86 via a lead wire, but is provided integrally with the holder main body 82.
