The wheel main body 71 is supported so as to be rotatable with respect to the support shaft S1. The support shaft S <b> 1 is fixed to an end cover 74 that closes the housing chamber 17 a that houses the worm wheel 70 formed in the clutch case 17 at the base end. Therefore, the worm wheel 70 (wheel main body 71) rotates forward and backward in the accommodating chamber 17a of the clutch case 17 about the support shaft S1 by the forward and reverse rotation of the worm shaft 18.

  As shown in FIGS. 5 and 6, the first driven shaft 75 is disposed on the same central axis O as the support shaft S <b> 1 that rotatably supports the wheel body 71. The first driven shaft 75 is rotatably inserted into a cylindrical second driven shaft 78. The cylindrical second driven shaft 78 is rotatably supported by the clutch case 17. Accordingly, the first driven shaft 75 is supported so as to be rotatable with respect to the clutch case 17 via the cylindrical second driven shaft 78.

  The first driven shaft 75 has a proximal end portion disposed in the accommodating chamber 17 a of the clutch case 17 and a distal end portion protruding from the clutch case 17. The first driven shaft 75 has a proximal end surface opposed to the distal end surface of the support shaft S1.

  As shown in FIG. 6, the first driven shaft 75 has two first engaging pieces 76 extending outward in the radial direction on the outer peripheral surface of the base end portion thereof. Specifically, the two first engagement pieces 76 are formed by recessing the outer peripheral surface of the base end portion. The two first engagement pieces 76 are formed to extend so as to face each other across the central axis of the first driven shaft 75 (the central axis O of the support shaft S1).

  The two first engagement pieces 76 are formed in a fan shape when viewed from the axial direction, and are formed so that the angle formed by the two planes in the circumferential direction is 90 °, and the two planes are in the circumferential direction. Perpendicular to each other, that is, flush with the straight line extending in the radial direction from the central axis O of the first driven shaft 75. In the present embodiment, these two planes are used as the engagement surfaces 77.

  As shown in FIG. 5, the front end portion of the first driven shaft 75 protruding from the clutch case 17 passes through the center position of the front frame portion 7 c of the system frame 7 from the upper surface f2 to the lower surface f1. A first pinion G1 is fixed to the outer peripheral surface of the tip end portion of the first driven shaft 75 protruding from the lower surface f1 of the system frame 7. The first pinion G1 rotates integrally with the first driven shaft 75.

  As shown in FIG. 5, the cylindrical second driven shaft 78 has a proximal end portion disposed in the clutch case 17 and a distal end portion protruding from the clutch case 17. A flange 78 a is formed at the base end of the cylindrical second driven shaft 78.

  As shown in FIGS. 5 and 6, two second engaging pieces 79 are adjacent to the inner peripheral surface of the outer ring portion 72 toward the inner bottom surface 80 from the outer peripheral portion of the flange 78 a on the outer peripheral portion of the flange 78 a. It is extended and formed. The two second engagement pieces 79 are formed to extend so as to face each other across the central axis of the cylindrical second driven shaft 78 (the central axis O of the support shaft S1).

  On the other hand, as shown in FIG. 5, the distal end portion of the cylindrical second driven shaft 78 protruding from the clutch case 17 passes through the center position of the front frame portion 7c of the system frame 7 from the upper surface f2 to the lower surface f1. . The second pinion G2 is fixed to the outer peripheral surface on the upper surface f2 side of the front frame portion 7c of the system frame 7, which is the tip portion of the second driven shaft 78 protruding from the clutch case 17. The second pinion G2 rotates together with the second driven shaft 78. Accordingly, the second pinion G2 is juxtaposed along the central axis O with respect to the first pinion G1.

  As shown in FIG. 6, four first guide members 81 having the same shape in the circumferential direction are formed at equiangular intervals on the inner bottom surface 80 surrounded by the outer ring portion 72 of the wheel body 71. The first guide member 81 has a fan shape with a central angle of 90 ° when viewed from the axial direction, and two circumferential planes perpendicular to each other serve as a first guide surface 81a. The first guide members 81 adjacent in the circumferential direction and the first guide surfaces 81a facing each other are parallel to each other.

  Further, four second guide members 82 having the same shape are formed on the inner bottom surface 80 on the radially inner side of the corresponding first guide member 81. The second guide member 82 has an L-shape bent at 90 ° when viewed from the axial direction, and two circumferential outer sides that are perpendicular to each other serve as a second guide surface 82a. Both the second guide surfaces 82a of the second guide member 82 are parallel to the first guide surfaces 81a on the corresponding side of the first guide member 81 formed on the radially outer side.

  And it is the 2nd guide member 82 adjacent to the circumferential direction, Comprising: The 2nd guide surfaces 82a which mutually oppose are parallel. Here, the interval between the parallel second guide surfaces 82a is shorter than the interval between the parallel first guide surfaces 81a.

Note that a radially outer plane that is bent at a right angle to the second guide surfaces 82a of the second guide member 82 and is continuous is referred to as a stopper surface 82b.
As shown in FIG. 6, two first operating pins 85 and two second operating pins 90 are arranged with respect to the inner bottom surface 80. More specifically, the first operating pin 85 and the second operating pin 90 are provided between the first guide surfaces 81a (between the second guide surfaces 82a) of the adjacent first guide members 81 (second guide members 82). They are alternately arranged at equiangular intervals in the circumferential direction. Accordingly, the two first operating pins 85 and the two second operating pins 90 are alternately arranged at intervals of 90 degrees in the circumferential direction.

  The first operating pin 85 is a rectangular parallelepiped whose first operating pin main body is long in the radial direction, and a pair of first sliding pieces 86 are extended and formed on the outer sides in the radial direction on both sides in the circumferential direction. . Then, the first operating pin 85 slides in the radial direction on the opposing second guide surfaces 82a of the second guide members 82 adjacent to each other in the circumferential direction located on the radially inner side of the first sliding piece 86. At the same time, the pair of first sliding pieces 86 are arranged so as to slide in the radial direction on the opposing first guide surfaces 81 a of the adjacent first guide members 81 and to be movable in the radial direction with respect to the inner bottom surface 80.

  At this time, the first actuating pin 85 is formed on the inner bottom surface 80 so as to coincide with a central line that bisects the circumferential direction (width direction in which the side is short) and a straight line extending in the radial direction from the central axis O of the support shaft S1. In contrast, it moves in the radial direction. The movement of the first operating pin 85 inward in the radial direction moves to a position where the stopper surface 82 b of the second guide member 82 engages with the first sliding piece 86.

  Further, the movement of the first operating pin 85 in the circumferential direction is restricted by the first guide surface 81 a facing the adjacent first guide member 81 and the second guide surface 82 a facing the adjacent second guide member 82. Is done. Accordingly, the first operating pin 85 rotates together with the worm wheel 70 (wheel main body 71), that is, turns around the center axis O of the support shaft S1 as a turning center.

  In the first operating pin 85, a first engagement protrusion 87 is formed to project at the center position of the radially inner side surface. The first engagement protrusion 87 engages with a first engagement piece 76 formed on the first driven shaft 75 when the first operating pin 85 moves radially inward.

  The first operating pin 85 is formed with a rectangular first spring housing chamber 88 that is elongated in the radial direction when viewed from the axial direction. More specifically, the first spring storage chamber 88 elongated in the radial direction has a straight line from the central axis O passing through the circumferential intermediate position thereof, and a straight line from the central axis O passing through the circumferential intermediate position of the first operating pin 85. It forms with respect to the 1st operating pin 85 so that it may correspond.

  A first support protrusion 89 protruding from the inner bottom surface 80 is inserted into the first spring storage chamber 88. When the first operating pin 85 is located at a position where the stopper surface 82 b of the second guide member 82 is engaged with the first sliding piece 86, the first supporting projection 89 is formed in the first spring accommodating chamber 88. It protrudes from the inner bottom surface 80 so as to be disposed at a position in contact with the inner surface on the radially outer side.

  In the first spring storage chamber 88, the first spring spring SP <b> 1 is disposed between the first support protrusion 89 and the radially inner inner surface of the first spring storage chamber 88. The first spring spring SP1 always applies an elastic force to the first operating pin 85 toward the radially inner side (the central axis O side of the support shaft S1).

  And if the wheel main body 71 rotates and the 1st action | operation pin 85 turns centering on the central axis O of the spindle S1, centrifugal force will be added. The force that moves the first operating pin 85 radially outward against the elastic force of the first spring spring SP1 is increased by the centrifugal force. Eventually, when the wheel main body 71 reaches the predetermined first rotational speed N1 and the first centrifugal force F1 is applied to the first operating pin 85, the first operating pin 85 moves further outward in the radial direction. It has become. At this time, the first operating pin 85 can move radially outward to a position where the first spring spring SP1 can no longer be contracted.

  Here, no centrifugal force is applied to the first operating pin 85, and the first operating pin 85 engages with the stopper surface 82b as shown in FIGS. 6, 7A, and 7B, A position where the first engagement protrusion 87 of the first operating pin 85 engages with the first engagement piece 76 of the first driven shaft 75 is referred to as a first position. Further, a centrifugal force equal to or greater than the first centrifugal force F1 is applied to the first operating pin 85, and the first operating pin 85 is separated from the stopper surface 82b as shown in FIG. The position where the first engagement protrusion 87 is disengaged from the first engagement piece 76 of the first driven shaft 75 is referred to as a second position.

  When the first operating pin 85 is disposed at the second position, the radially outer surface of the first operating pin 85 (the surface opposite to the radially inner surface on which the first engagement protrusion 87 is formed). Is located on the inner side of the second engagement piece 79 of the second driven shaft 78, and the first operating pin 85 and the second engagement piece 79 do not collide.

  Similarly, the second operating pin 90 is a rectangular parallelepiped whose second operating pin body has the same shape as the first operating pin 85 and is long in the radial direction. A second sliding piece 91 is formed to extend. Then, the second operating pin 90 slides in the radial direction on the opposing second guide surfaces 82a of the second guide members 82 adjacent to each other in the circumferential direction located on the radially inner side of the second sliding piece 91. At the same time, the pair of second sliding pieces 91 are arranged so as to slide in the radial direction on the opposing first guide surfaces 81 a of the adjacent first guide members 81 and move in the radial direction with respect to the inner bottom surface 80.

  At this time, like the first operating pin 85, the second operating pin 90 includes a center line that bisects the circumferential direction (width direction in which the side is short) and a straight line that extends in the radial direction from the center axis O of the support shaft S1. It moves in the radial direction with respect to the inner bottom surface 80 so as to match. Then, the movement of the second operating pin 90 inward in the radial direction moves to a position where the stopper surface 82 b of the second guide member 82 engages with the second sliding piece 91.

  Further, the movement of the second operating pin 90 in the circumferential direction is restricted by the first guide surface 81 a facing the adjacent first guide member 81 and the second guide surface 82 a facing the adjacent second guide member 82. Is done. Therefore, the second operating pin 90 rotates together with the worm wheel 70 (wheel main body 71), that is, turns around the center axis O of the support shaft S1 as a turning center.

  In the second operating pin 90, a second engaging projection 92 is formed to protrude at the center position of the radially outer side surface. The second engagement protrusion 92 is adapted to engage with a second engagement piece 79 formed on the second driven shaft 78 when the second operating pin 90 moves radially outward.

  A rectangular second spring housing chamber 93 elongated in the radial direction when viewed from the axial direction is formed through the second operating pin 90 in the axial direction. More specifically, the second spring storage chamber 93 elongated in the radial direction has a straight line from the central axis O passing through the circumferential intermediate position thereof, and a straight line from the central axis O passing through the circumferential intermediate position of the second operating pin 90. It forms with respect to the 2nd actuating pin 90 so that it may correspond.

  A second support protrusion 94 protruding from the inner bottom surface 80 is inserted into the second spring storage chamber 93. When the second operating projection 90 is located at a position where the stopper surface 82 b of the second guide member 82 is engaged with the second sliding piece 91, the second supporting projection 94 is moved to the second spring accommodating chamber 93. It protrudes from the inner bottom surface 80 so as to be in a position where it abuts against the radially inner side surface.

  In the second spring storage chamber 93, the second spring spring SP <b> 2 is disposed between the second support protrusion 94 and the inner surface on the radially inner side of the second spring storage chamber 93. The second spring spring SP2 always applies an elastic force to the second operating pin 90 toward the radially inner side (the central axis O side of the support shaft S1).

  And if the wheel main body 71 rotates and the 2nd operation pin 90 turns centering on the central axis O of the spindle S1, centrifugal force will be added. The second operating pin 90 increases the force that moves radially outward against the elastic force of the second spring spring SP2 due to the centrifugal force.

  Eventually, when the wheel body 71 reaches a predetermined second rotational speed N2 (> N1) having a rotational speed larger than the first rotational speed N1, and the second centrifugal force F2 is applied to the second operating pin 90, The second operating pin 90 moves further outward in the radial direction against the elastic force of the second spring spring SP2.

  When no centrifugal force is applied to the second operating pin 90, the second operating pin 90 has its second sliding piece 91 engaged with the stopper surface 82b of the second guide member 82, and the diameter is further increased. Movement inward in the direction is restricted. At this time, the radially inner side surface of the second operating pin 90 (the surface opposite to the radially outer surface on which the second engagement protrusion 92 is formed) is from the first engagement piece 76 of the first driven shaft 75. Is also located on the outer side, and the second operating pin 90 and the first engagement piece 76 do not collide.

  Here, no centrifugal force equal to or greater than the second centrifugal force F2 is applied to the second operating pin 90, and the second operating pin 90 does not move radially outward as shown in FIG. The position where the second engagement protrusion 92 of the second operating pin 90 is disengaged from the second engagement piece 79 of the second driven shaft 78 is referred to as a third position. Further, when the second centrifugal force F2 is applied to the second operating pin 90, the second operating pin 90 further moves radially outward as shown in FIG. A position where the engagement protrusion 92 engages with the second engagement piece 79 of the second driven shaft 78 is referred to as a fourth position.

  In other words, in the present embodiment, when the wheel main body 71 rotates at less than the first rotation speed N1, the first operating pin 85 is in the first position. At this time, the second operating pin 90 is in the third position because the wheel body 71 rotates at a rotation speed less than the second rotation speed N2 and less than the first rotation speed N1.

  Accordingly, the first engagement protrusion 87 and the first engagement piece 76 are engaged, the second engagement protrusion 92 and the second engagement piece 79 are disengaged, and the rotational force of the worm wheel 70 is the first. It is transmitted to the driven shaft 75. That is, the first engagement piece 76, the first operating pin 85, the first spring spring SP1, and the like constitute a centrifugal clutch (first centrifugal clutch). Then, when the first pinion G1 rotates forward and backward, the pair of left and right first drive cables 11a and 11b are push-pull driven to open and close the sun shade 5.

  Further, when the wheel body 71 is rotating at the first rotation speed N1, the first operating pin 85 is in the second position. At this time, the second operating pin 90 is in the third position because the wheel main body 71 rotates at the first rotation speed N1 that is smaller than the second rotation speed N2.

  Accordingly, the first engagement protrusion 87 and the first engagement piece 76, and the second engagement protrusion 92 and the second engagement piece 79 are disengaged, and the rotation of the worm wheel 70 is It is not transmitted to the first driven shaft 75 and the second driven shaft 78.

  Further, when the wheel main body 71 is rotating at the second rotation speed N2 or higher, which is higher than the first rotation speed N1, the second operating pin 90 is in the fourth position. At this time, the first operating pin 85 rotates at a second rotational speed N2 that is greater than the first rotational speed N1, but the first spring spring SP1 cannot be further contracted. In the second position.

  Accordingly, the first engagement protrusion 87 and the first engagement piece 76 are disengaged, the second engagement protrusion 92 and the second engagement piece 79 are engaged, and the rotational force of the worm wheel 70 is It is transmitted to the second driven shaft 78. That is, the second engagement piece 79, the second operating pin 90, the second spring spring SP2, and the like constitute a centrifugal clutch (second centrifugal clutch). Then, when the second pinion G2 rotates forward and backward, the pair of left and right second drive cables 12a and 12b are push-pull driven to open and close the roof glass 4.

  Incidentally, the outer diameter D1 of the first pinion G1 and the outer diameter D2 of the second pinion G2 are the peripheral speed of the outermost periphery of the first pinion G1 and the outer periphery of the second pinion G2, as in the above embodiments. The speed is set to be the same peripheral speed. The opening / closing movement speed of the sunshade 5 and the opening / closing movement speed of the roof glass 4 are the same.

As shown in FIG. 4, an electronic control unit (ECU) 40 is provided in the clutch case 17 of the deceleration / clutch unit 16.
The ECU 40 is a control circuit that controls the rotation of the motor M, and includes a microcomputer. The ECU 40 receives operation signals from a first operation switch 41 for opening and closing a sunshade and a second operation switch 42 for opening and closing a roof glass provided at the driver's seat. When the ECU 40 receives an open / close operation signal or a stop operation signal from the first operation switch 41, the ECU 40 controls the rotation of the motor M in order to open / close the sunshade 5 or stop the open / close operation. When the ECU 40 receives an open / close operation signal or a stop operation signal from the second operation switch 42, the ECU 40 controls the rotation of the motor M to open or close the roof glass 4.

  More specifically, when an opening operation signal is output from the first operation switch 41, the ECU 40 determines that the operation is to open the sunshade 5, and the motor M is rotated forward and the wheel body 71 is rotated in the first rotation. The rotation is controlled so as to rotate forward at a rotation speed smaller than the number N1. On the other hand, when a closing operation signal is output from the first operation switch 41, the ECU 40 determines that the operation is to close the sunshade 5, the motor M is rotated in the reverse direction, and the wheel body 71 has the first rotation speed. The rotation is controlled so as to reversely rotate at a rotation speed smaller than N1.

When a stop operation signal is output from the first operation switch 41, the ECU 40 determines that the operation is to stop the opening / closing operation of the sunshade 5, and stops the rotation of the motor M.
On the other hand, when an opening operation signal is output from the second operation switch 42, the ECU 40 determines that the operation is to open the roof glass 4, the motor M is rotated forward, and the wheel body 71 is rotated at the second rotational speed. The rotation is controlled so as to rotate forward at a rotational speed greater than N2. On the other hand, when a closing operation signal is output from the second operation switch 42, the ECU 40 determines that the operation is to close the roof glass 4, and the motor M is rotated in the reverse direction, and the wheel body 71 is rotated in the second rotation. The rotation is controlled so as to reversely rotate at a rotation speed larger than the number N2.

When a stop operation signal is output from the second operation switch 42, the ECU 40 determines that the operation is to stop the opening / closing operation of the roof glass 4, and stops the rotation of the motor M.
Next, the operation of the embodiment configured as described above will be described.

When the rotational speed is less than the first rotational speed, the rotational force of the wheel main body 71 (motor M) is transmitted. The second driven shaft 78 (second pinion G2) is a second centrifugal clutch including the second operating pin 90, the second spring spring SP2, the second engagement piece 79, etc., and the rotation speed of the wheel body 71 is high. When the rotational speed is equal to or higher than the second rotational speed, the rotational force of the wheel body 71 (motor M) is transmitted.

  Therefore, the first drive cables 11a and 11b and the second drive cables 12a and 12b perform push-pull drive with the system frame 7 interposed therebetween. As a result, the first drive cables 11a and 11b and the second drive cables 12a and 12b do not interfere with each other.

  This eliminates the work of bending the first drive cables 11a and 11b and the second drive cables 12a and 12b to avoid interference. In addition, it is not necessary to secure the bending and handling space for bending the first drive cables 11a and 11b and the second drive cables 12a and 12b.
