  In order to increase the accuracy of rotation detection by the magnetic sensor 76 and the sensor magnet 77, the position of the magnetic sensor 76 relative to the sensor magnet 77, that is, the positioning accuracy of the control substrate 65 on which the magnetic sensor 76 is mounted inside the substrate housing chamber 64. Need to be increased.

  Therefore, in the opening / closing device 21, the control substrate 65 is positioned in the insertion direction in the substrate storage chamber 64 by sandwiching the control substrate 65 between the bottom portion 64a of the substrate storage chamber 64 and the contact portion 71c of the cover 71. In addition, a positioning structure 91 as a positioning means is provided separately from the guide rail 66, and the control board 65 is positioned by the positioning structure 91 in a direction orthogonal to the insertion direction, that is, in the width direction. As shown in FIG. 8, the positioning structure 91 includes a concave portion 91 a provided in the control substrate 65 and a convex portion 91 b provided in the bottom portion 64 a of the substrate storage chamber 64.

  The concave portion 91a is formed on an end edge 65a on the front side in the insertion direction of the control substrate 65 into the substrate storage chamber 64, that is, on the end side 65a on the side facing the bottom portion 64a of the substrate storage chamber 64. Is provided. The end side 65 a is orthogonal to the insertion direction of the control substrate 65 into the substrate storage chamber 64. The recess 91a is formed in a groove shape that opens to the end side 65a and extends from the recess 65a toward the opening along the insertion direction, and the groove width is constant. In addition, the recess 91 a includes a board-side power supply terminal 74 disposed at a position near one side of the end side 65 a of the control board 65, that is, one guide rail 66, and the end side 65 a of the control board 65. The magnetic sensor 76 is disposed adjacent to the magnetic sensor 76 disposed in a substantially central portion in the vicinity in the width direction.

  On the other hand, the convex portion 91b is formed in a block shape integrally with the case 31 on the bottom portion 64a of the substrate housing chamber 64, and extends in the insertion direction from the bottom portion 64a toward the opening with a substantially same width as the concave portion 91a. . The tip of the convex portion 91b is formed in a semi-cylindrical shape, and the concave portion 91a is easily engaged with the convex portion 91b. Further, the protruding amount of the convex portion 91b from the bottom 64a of the substrate housing chamber 64 toward the opening is made larger than the protruding amount of the motor-side power supply terminal 75 into the substrate housing chamber 64. Thus, when the control board 65 is inserted into the board housing chamber 64, the concave portion 91a of the positioning structure 91 is engaged with the convex portion 91b before the board-side power supply terminal 74 is connected to or engaged with the motor-side power supply terminal 75. It is supposed to be.

  Next, a procedure for housing the control board 65 in the board housing chamber 64 will be described with reference to FIG.

  First, as shown in FIG. 9A, the control board 65 is inserted into the board housing chamber 64 of the case 31 with the cover 71 removed from the opening. At this time, the control board 65 engages with the guide rail 66 on both sides thereof, and is guided by the guide rail 66 and moves from the opening toward the bottom 64a.

  When the control board 65 is guided to the guide rail 66 and inserted to the position just before the bottom 64a, the tip portion of the convex portion 91b provided on the case 31 is located on the control board 65 as shown in FIG. It enters from the insertion direction into the recess 91a provided on the end side 65a, and these engage with each other. At this time, the board-side power supply terminal 74 provided on the control board 65 is not yet engaged with the motor-side power supply terminal 75 protruding into the board housing chamber 64. That is, when the control board 65 is inserted into the board housing chamber 64, before the board-side power supply terminal 74 is engaged with the motor-side power supply terminal 75, the concave portion 91 a is engaged with the convex portion 91 b and the case of the control board 65. Positioning in a direction orthogonal to the insertion direction with respect to 31 is performed. In other words, the engagement margin L1 between the projection 91a and the recess 91b in the positioning structure 91 and the engagement margin L2 between the motor-side feeding terminal 75 and the board-side feeding terminal 74 are set to be larger. ing.

  After the concave portion 91a is engaged with the convex portion 91b, when the control board 65 is further pushed toward the back of the substrate housing chamber 64, the board-side power supply terminal 74 is engaged with the motor-side power supply terminal 75, and these are connected to each other. Is done. At this time, since both the concave portion 91a and the convex portion 91b are formed so as to extend in the insertion direction, the engagement is maintained and the positioning structure 91 positions the control board 65 in the direction orthogonal to the insertion direction with respect to the case 31. Is also maintained.

  When the control board 65 is inserted to a position where it comes into contact with the bottom 64 a of the board storage chamber 64, the insertion work is completed, and then the cover 71 is attached to the case 31. When the cover 71 is attached to the case 31, the control board 65 is also positioned in the insertion direction by being sandwiched between the bottom part 64a of the board housing chamber 64 and the contact part 71c of the cover 71. In this state, as shown in FIG. 4, the cover 71, the control board 65, and the case 31 are fastened by the screw member 92, and the control board 65 is fixed at a predetermined position in the board housing chamber 64 of the case 31. Will be.

  As described above, the opening / closing device 21 is provided with the positioning structure 91 including the concave portion 91a and the convex portion 91b that are engaged with each other in the insertion direction, in addition to the guide rail 66 that guides the control board 65 in the insertion direction. Since the concave portion 91a and the convex portion 91b are engaged before the substrate-side power supply terminal 74 is connected to the motor-side power supply terminal 75 when the substrate 65 is inserted into the substrate housing chamber 64, the motor-side power supply Regardless of the connection state between the terminal 75 and the board-side power supply terminal 74, the control board 65 can be accurately positioned in the board housing chamber 64 in the direction orthogonal to the insertion direction by the positioning structure 91. Thereby, the position accuracy of the magnetic sensor 76 with respect to the sensor magnet 77 can be increased, and the rotation detection accuracy of the driving drum 33 by the magnetic sensor 76 can be increased.

  Further, in this switchgear 21, the recess 91a is formed in a groove shape in the portion between the magnetic sensor 76 and the substrate-side power supply terminal 74 on the end side 65a on the front side in the insertion direction of the control substrate 65, and the protrusion 91b is formed on the substrate. Since it is formed on the bottom portion 64a of the storage chamber 64, the configuration of the positioning structure 91 can be simplified to reduce the cost, and the positioning accuracy of the control substrate 65 in the substrate storage chamber 64 can be further increased.

  10A and 10B are front views showing modifications of the positioning structure shown in FIG.

  In the positioning structure 91 shown in FIG. 8, the concave portion 91a is formed in a groove shape extending with a constant width along the insertion direction, and the convex portion 91b is formed in a block shape extending with a constant width along the insertion direction. However, the present invention is not limited to this, and any structure that can be engaged with each other in the insertion direction, such as forming the recess 91a in a V shape as shown in FIG.

  Further, in the positioning structure 91 shown in FIG. 8, the concave portion 91 a is provided between the magnetic sensor 76 on the end side 65 a of the control board 65 and the board-side power supply terminal 74. It may be provided at any position on the end side 65a. For example, as shown in FIG. 10B, the positioning accuracy of the magnetic sensor 76 with respect to the sensor magnet 77 can be further increased by providing the recess 91a between the pair of magnetic sensors 76.

  Further, in the positioning structure 91 shown in FIG. 8, the concave portion 91 a is provided on the end side 65 a of the control substrate 65 and the convex portion 91 b is provided on the bottom portion 64 a of the substrate housing portion 64 b of the case 31. Alternatively, the convex portion 91 b may be provided on the end side 65 a of the control substrate 65, and the concave portion 91 a may be provided on the bottom portion 64 a of the substrate housing portion 64 b of the case 31.

  Also in the modified example as shown in FIG. 10B, the allowance L1 between the convex portion 91a and the concave portion 91b in the positioning structure 91, and the allowance L2 between the motor side power supply terminal 75 and the board side power supply terminal 74. Means that the engagement margin L1 is set larger.

  FIG. 11 is a front view showing details of the brush holder mounted on the case, and FIG. 12 is a cross-sectional view taken along the line AA in FIG.

  In the switchgear 21, when the control board 65 is inserted into the board housing chamber 64, the motor side power supply terminal 75 is connected to the case side in order to securely connect the board side power supply terminal 74 to the motor side power supply terminal 75 on the case 31 side. 31 is positioned in the substrate storage chamber 64.

  As shown in FIG. 11, each motor-side power supply terminal 75 is provided on the brush holder 51 b of the electric motor 51. The brush holder 51b is formed in a substantially oval plate shape, and a through hole 93 is provided in the axial center thereof. On the other hand, a cylindrical positioning boss 94 that is coaxial with the armature shaft 51 c is provided at the shaft center of the holder accommodating portion 53 of the case 31, and the brush holder 51 b is disposed on the outer periphery of the positioning boss 94 at the inner periphery of the through hole 93. It is inserted from the axial direction and positioned inside the holder accommodating portion 53 of the case 31 around the axis of the armature shaft 51c. A commutator 95 fixed to the armature shaft 51c is positioned in the through-hole 93 of the brush holder 51b accommodated in the holder accommodating portion 53, and a pair of brushes 96 held by the brush holder 51b is connected to the commutator 95. It comes in sliding contact with the outer periphery. The pair of motor-side power supply terminals 75 are fixed to both side portions of the brush holder 51b at their base portions and are parallel to each other and project outward from the brush holder 51b in the radial direction. And a choke coil 97, a circuit breaker 98, etc., are electrically connected to the corresponding brush 96.

  In the partition wall 101 that partitions the holder housing portion 53 of the case 31 and the substrate housing chamber 64, a pair of slits 102 a, 102b are arranged in parallel with each other at a predetermined interval. As shown in FIG. 12, these slits 102a and 102b have a concave shape opened to one end of the partition wall 101 of the case 31 on the same side as the side where the holder accommodating portion 53 opens, and the brush holder 51b accommodates the holder. When accommodated in the portion 53 from the axial direction, each motor-side power supply terminal 75 is inserted into the corresponding slit 102a, 102b from its opening. At this time, since the brush holder 51b can be slightly rotated around the positioning boss 94, the position of the motor-side power supply terminal 75 relative to the slits 102a and 102b can be adjusted by this rotation. The motor-side power supply terminal 75 inserted into the slits 102 a and 102 b is positioned with respect to the case 31 by these slits 102 a and 102 b, and the tip portion protrudes from the holder housing portion 53 to the substrate housing chamber 64.

  Here, in the opening / closing device 21, the width (gap) w1 of one slit 102a is set to be equal to or slightly narrower than the thickness W of the corresponding motor-side power supply terminal 75, and the other slit 102b has its width ( The gap w2 is set to be slightly wider than the thickness W of the corresponding motor-side power supply terminal 75.

  That is, by setting the width w1 of one slit 102a to be equal to or slightly narrower than the thickness W of the corresponding motor-side power supply terminal 75, the motor-side power supply terminal 75 is lightly press-fitted into the slit 102a. Yes. As a result, the motor-side power supply terminal 75 can be accurately positioned with respect to the case 31 by the slit 102a. On the other hand, since the width w2 of the other slit 102b is set wider than the thickness W of the corresponding motor-side power supply terminal 75, even if there is a dimensional error in the distance between the motor-side power supply terminals 75, the error Can be absorbed by the gap formed by the slit 102b that is set wider, and both the motor-side power supply terminals 75 can be easily inserted into the corresponding slits 102a and 102b.

  With this configuration, in the opening / closing device 21, the brush holder 51b is positioned on the case 31 with the positioning boss 94 as the center of the axis of the armature shaft 51c, and a pair of motor-side power supply terminals 75 provided on the brush holder 51b are provided. The slits 102 a and 102 b provided in the case 31 can be accurately positioned in the substrate housing chamber 64 of the case 31. In addition, since one slit 102a into which the motor-side power supply terminal 75 is inserted is set to light press-fit, and the other slit 102b is set to a gap, high accuracy is achieved as component accuracy and mounting accuracy of the brush holder 51b and each motor-side power supply terminal 75. Therefore, it is possible to easily engage each of the motor-side power supply terminals 75 with the slits 102a and 102b.

  FIG. 13 is a perspective view showing details of the claw portion of the cover and the engagement protrusion of the case, and FIG. 14 is a cross-sectional view showing a state where the claw portion and the engagement protrusion are engaged.

  As described above, the control substrate 65 is positioned in the insertion direction in the substrate storage chamber 64 by sandwiching the control substrate 65 between the bottom portion 64a of the substrate storage chamber 64 and the contact portion 71c provided on the cover 71. Is called. In the switchgear 21, even if the control board 65, the case 31, and the cover 71 have a dimensional error within the tolerance, the control board 65 is reliably connected between the contact portion 71 c of the cover 71 and the bottom portion 64 a of the substrate housing chamber 64. In order to fix, the engaging surface 111 of the claw portion 71b of the cover 71 and the engaged surface 112 of the engaging projection 72 are inclined with respect to the direction perpendicular to the insertion direction of the control board 65, respectively. The dimensional error is absorbed by moving the engaging surface 111 of the claw portion 71 b along the inclination with respect to the engaged surface 112 of the engaging protrusion 72.

  As shown in FIGS. 13 and 14, the claw portion 71 b provided in the cover 71 is formed in a plate shape having an engagement hole 113, and is a portion bent into a U shape on both side portions, that is, both side wall portions of the main body portion 71 a. And extends parallel to the side wall. The engagement surface 111 of the claw portion 71b is provided on one end side of the engagement hole 113 facing the main body portion 71a. On the other hand, the engaging protrusions 72 provided on both sides of the cover 71, that is, both side walls, are formed in a block shape smaller than the engaging hole 113 of the claw portion 71b. It is provided on one end side facing away from the cover 71. The engaging surface 111 and the engaged surface 112 are each in the width direction of the case 31 with respect to the insertion direction of the control board 65, that is, the direction orthogonal to the mounting direction of the cover 71 to the case 31 (the width direction of the case or cover). Inclined in a direction gradually approaching the cover 71 from the outside to the inside.

  When the cover 71 is attached to the case 31, the claw portions 71 b are elastically deformed in the width direction relative to the main body portion 71 a so as to get over the corresponding engagement protrusions 72 and enter the engagement holes 113. When the engaging protrusion 72 enters, as shown in FIG. 14, the engaging surface 111 of the claw portion 71 b engages with the engaged surface 112 of the engaging protrusion 72, and the cover 71 is fixed to the case 31.

  Here, in this opening / closing device 21, the engaging surface 111 of the claw portion 71 b and the engaged surface 112 of the engaging projection 72 are both inclined, so that the claw portion 71 b is engaged with the engaging projection 72. For this, it is necessary to first push the engaging surface 111 of the claw portion 71 b to a position beyond the engaged surface 112 of the engaging protrusion 72 and then engage the engaged surface 112 of the engaging protrusion 72. For this reason, as shown in FIG. 14, a slight gap t is provided between the both side portions of the main body 71 a of the cover 71 and the opening end portion of the case 31 in the mounting direction of the cover 71. As a result, the cover 71 can be elastically deformed in a bow shape in a direction in which both sides thereof approach the case 31 with the contact portion 71c contacting the control board 65 as a center, and the engagement surface 111 of the claw portion 71b is formed. It can be moved to a position beyond the engaging protrusion 72 and engaged with the engaged surface 112.

  In the opening / closing device 21, since the engaging surface 111 of the claw portion 71b and the engaged surface 112 of the engaging protrusion 72 are both inclined, the control board 65, the case 31, and the cover 71 are covered with the cover 71 for the case 31. Even if there is a dimensional error in the mounting direction, the dimensional error is absorbed by the engaging surface 111 of the claw portion 71b moving along the inclination with respect to the engaged surface 112 of the engaging protrusion 72. Can do.

  FIGS. 15A and 15B are explanatory views showing how dimensional errors are absorbed in the engaging portions of the claw portion and the engaging protrusion, respectively.

  For example, as shown in FIG. 15A, the position of the cover 71 is shifted in a direction away from the regular position shown in FIG. 14 due to the dimensional error of the control board 65, the case 31, and the cover 71. In this case, the engaging surface 111 of the claw portion 71 b moves along the engaged surface 112 of the engaging protrusion 72 toward the root side of the engaging protrusion 72, that is, the inner side in the width direction of the case 31. Thereby, the engagement position of the claw portion 71b with respect to the engagement protrusion 72 is shifted to the opening side of the case 31 with respect to the normal position, and the position shift of the cover 71 is absorbed. On the other hand, as shown in FIG. 15B, due to the dimensional error of the control board 65, the case 31, and the cover 71, the position of the cover 71 is shifted in the direction approaching the case 31 with respect to the normal position shown in FIG. In this case, the engaging surface 111 of the claw portion 71 b moves along the engaged surface 112 of the engaging protrusion 72 toward the distal end side of the engaging protrusion 72, that is, outward in the width direction of the case 31. Thereby, the engagement position of the claw portion 71b with respect to the engagement protrusion 72 is shifted to the side away from the opening of the case 31 with respect to the normal position, and the position shift of the cover 71 is absorbed. That is, the shift in the insertion direction of the cover 71 is absorbed by the amount that the engagement position between the claw portion 71b and the engagement protrusion 72 is shifted in the inclination direction, and therefore, the control board 65, the case 31, and the cover 71 are absorbed. Even if the position of the cover 71 is shifted from the normal position shown in FIG. 14 due to the dimensional error, the control substrate 65 is reliably positioned between the bottom 64a of the substrate storage chamber 64 and the contact portion 71c of the cover 71. In addition, it is possible to prevent an excessive bending load centering on the contact portion 71c from being applied to the cover 71 and to enhance its durability.

  Thus, in this opening / closing device 21, the engaging surface 111 of the claw portion 71b for fixing the cover 71 to the case 31 and the engaged surface 112 of the engaging protrusion 72 that engages with the claw portion 71b are respectively provided. Since the control board 65 is provided so as to be inclined with respect to the direction orthogonal to the insertion direction of the control board 65, the variation in the insertion direction of the cover 71, the case 31, and the control board 65 is related to the engagement surface 111 of the claw portion 71b. It can be absorbed by a change in the engagement position of the mating protrusion 72 with the engaged surface 112. Accordingly, the cover 71 is fixed at an appropriate position with respect to the case 31 without applying an excessive bending load, and the control board is securely connected between the contact portion 71c of the cover 71 and the bottom portion 64a of the substrate storage chamber 64. Can be fixed.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above-described embodiment, the present invention is applied to the cable-type opening / closing device 21 for driving the sliding door 13 to open and close. However, the present invention is not limited to this, for example, the back door (tailgate) of the vehicle 11.
