  Under this locking position, a pulling force by the open side cable 21 is applied to the lever member 33 via the pulley shaft 34, and the pulling force by the open side cable 21 is applied to the lever member 33 as indicated by an arrow in the figure. It acts on the shaft holding surface 36b of 33 toward the vehicle front side (the cable drawing direction side from the pulley body 31). Therefore, since the shaft center CL of the lever shaft 38 is arranged offset to the vehicle interior side with respect to the shaft center CP of the pulley shaft 34, the open side cable 21 acting on the lever member 33 is provided on the lever member 33. The moment in the direction of rotating the lever member 33 in one direction of rotation from the release position to the locking position (clockwise direction in the figure) acts on the lever shaft 38 as an axis by the pulling force of Become.

  That is, the shaft center CP of the pulley shaft 34 is parallel to the line of action L of the pulling force applied by the open cable 21 applied to the lever member 33 and passes through the axis CL of the lever shaft 38. 38 is disposed so as to be shifted to one side in the rotational direction with the axis 38 as an axis. For this reason, due to the pulling force of the open-side cable 21 applied to the lever member 33, a moment in the direction of rotating the lever member 33 to one side in the rotation direction acts on the lever member 33 with the lever shaft 38 as an axis. The lever member 33 is held in the locking position by this moment.

  On the other hand, as shown in FIG. 10, when the lever member 33 is in the released position, the lever shaft 38 is pivoted from the locking position to the other side in the rotational direction (counterclockwise direction side in the figure). The lever member 33 is disposed at the pivoted position, and the lever member 33 protrudes from the opening on the vehicle interior side of the case half 42 to the vehicle interior side. At this time, the pair of guide wall portions 36 of the lever member 33 are arranged so as not to wrap in the axial direction of the pulley shaft 34 with respect to the slot 45. As a result, the pulley shaft 34 is movable in the slot 45 along the longitudinal direction thereof, and the pulley main body 31 moves in the vehicle longitudinal direction between the surplus length releasing position shown in FIG. 9 and the surplus length generating position shown in FIG. It has become freely movable.

  Next, the operation of the pulley unit 24 when routing the open cable 21 between the drive unit 23 and the roller assembly 17 of the slide door 14 will be described.

  First, the open-side cable 21 drawn out from the drive unit 23 is wound around the pulley body 31 of the pulley unit 24 and routed along the center rail 15 toward the slide door 14 side. In the pulley unit 24, the lever member 33 is rotated to the release position, and the pulley body 31 is movable between the extra length release position and the extra length generation position. In this state, by pulling the other end of the open side cable 21 drawn to the slide door 14 side toward the vehicle front side, the pulley body 31 is moved to the surplus length generation position by the pulling force of the open side cable 21.

  When the pulley main body 31 is in the surplus length generating position, the pulley main body 31 is arranged on the cable drawing direction side (vehicle front side) from the surplus length releasing position, and the open side cable routed in the pulley case 32 The cable length of the open-side cable 21 drawn out from the pulley unit 24 to the slide door 14 side is increased by the amount that the cable length of 21 is reduced. As a result, when the other end of the open cable 21 is locked to the roller assembly 17 of the slide door 14, a sufficient cable length of the open cable 21 can be secured, and the other end of the open cable 21 can be secured. The roller assembly 17 can be easily locked.

  After the routing of the open cable 21 is completed, the lever member 33 is turned to one side in the turning direction with the lever shaft 38 as an axis, and the lever member 33 is turned to the locking position. At this time, the pulley shaft 34 is guided to the vehicle rear side along the slot 45 by the guide surfaces 36a of the pair of guide wall portions 36 in accordance with the turning operation of the lever member 33, and the pulley main body 31 is moved to the extra length generation position. To the extra length release position. Then, when the pulley shaft 34 is sandwiched between the side surface on the vehicle rear side of the slot 45 and the shaft holding surface 36b of the guide wall portion 36, the pulley shaft 34 is locked under the excess length releasing position. Further, the lever member 33 is engaged when the locking claw 40 and the locking hole 51 are engaged, and a moment in a direction for rotating the lever member 33 to one side in the rotation direction acts on the lever member 33. It is held in the stop position. When the pulley body 31 is in the extra length release position, the open cable 21 is routed between the drive unit 23 and the slide door 14 without looseness, and the open cable 21 is provided on the drive unit 23. A predetermined tension is applied by the tensioner mechanism.

  Thus, in the pulley unit 24 of the present embodiment, the locking position for locking the pulley shaft 34 under the surplus length release position and the locking of the pulley shaft 34 under the surplus length release position are performed. The lever member 33 that is rotated to the release position to be released is assembled to the pulley case 32 so as to be rotatable. This lever member 33 makes it possible to hold the pulley body 31 in the excess length release position.

  Further, in the pulley unit 24 of the present embodiment, the lever member 33 extends in parallel with the line of action L of the pulling force by the open-side cable 21 applied to the lever member 33 under the locking position, and the lever shaft 38. By disposing the shaft center CP of the pulley shaft 34 to one side in the rotational direction with respect to the straight line M passing through the shaft center CL of the lever, the pulling force by the open cable 21 acting on the lever member 33 causes the lever A moment in a direction of rotating the member 33 in one direction of rotation is applied to the lever member 33. As a result, the lever member 33 can be held in the locking position without providing a fixing member such as a bolt, and the operation of holding the pulley body 31 in the excess length releasing position becomes easy and the number of parts is reduced. As a result, the cost and weight of the pulley unit 24 can be reduced.

  The resin pulley case 61 is an axially divided type having a pair of case halves 68 and 69 divided in the axial direction of the pulley shaft 34, that is, in the vehicle vertical direction.

  The first case half 68 disposed on the vehicle upper side includes a bottomed case portion 70 that opens to the vehicle lower side, and the case portion 70 has a shape that can accommodate the pulley body 31. As shown in FIG. 17, a slot (long hole) 71 that opens to the vehicle lower side is formed in the bottom wall 70 a of the case portion 70, and the slot 71 extends along the cable pulling direction from the pulley body 31. It extends in the front-rear direction. Further, an assembly groove 72 for rotatably accommodating the shaft drive unit 63 on the vehicle upper side of the pair of shaft drive units 63 of the lever member 62 is opened on the vehicle lower side on the bottom wall 70a of the case member 70. Is formed. The assembly groove 72 includes a guide groove portion 72a as a guide portion for guiding the guided portion 63b of the shaft driving portion 63, which is positioned on the vehicle front side, that is, the cable drawing direction side from the pulley body 31 with respect to the slot 71. ing. The guide groove 72a is formed to bend toward the vehicle rear side as it goes toward the vehicle interior side.

  A cap attachment half 70b is provided on the side of the vehicle interior of the case 70 at the cable drawing position from the case half 68 to the drive unit 23, and the cap attachment half 70b opens to the vehicle lower side. A stepped groove is provided. A locking hole 73 that penetrates in the axial direction of the pulley shaft 34 is formed in the cap mounting half 70 b. In addition, the case half 68 is provided with a bracket portion 74 that extends from the case portion 70 to the upper side of the vehicle. The bracket portion 74 is integrally provided with the case portion 70. A penetrating mounting hole 74a is formed.

  On the other hand, the second case half 69 disposed on the vehicle lower side includes a case portion 76 disposed to face the case portion 70 of the case half 68, and the case portion 76 is an opening of the case portion 70. The cover shape can be closed. Similar to the bottom wall 70 a of the case portion 70, the bottom wall 76 a of the case portion 76 has a slot 71 extending in the vehicle front-rear direction along the direction of pulling out the cable from the pulley body 31, and a shaft on the vehicle lower side of the lever member 62. An assembly groove 72 for rotatably accommodating the drive unit 63 is formed to open on the vehicle upper side.

  A cap attachment half 76 b is provided on the side of the vehicle interior of the case portion 76 at the cable drawing position from the case half 69 to the drive unit 23, and the cap attachment half 76 b is a part of the case half 68.

A through hole (not shown) that penetrates is formed.

  The pair of case halves 68 and 69 are assembled together from the axial direction of the pulley shaft 34 in a state where the pulley body 31 and the lever member 62 are accommodated in the case portions 70 and 76, and the opening side of the case portion 70 is the case portion 76. The pulley case 61 is formed by being closed. The case portion 70 is formed with openings that open to the vehicle front side and the vehicle lower side at the cable drawing position from the case half 68 to the slide door 14, and the vehicle lower side of the opening portion is formed by the case portion 76. By being closed, a cable lead-out hole 78 is formed between the case halves 68 and 69. The open cable 21 is drawn from the pulley body 31 toward the slide door 14 toward the front side of the vehicle through the cable drawing hole 78.

  Further, the end cap 26a is held by the pulley case 61 by assembling the case halves 68 and 69 with the end cap 26a fitted into the cap mounting half 70b. The open cable 21 drawn from the pulley body 31 toward the drive unit 23 toward the vehicle front side is inserted between the pair of shaft drive parts 63 of the lever member 62 or the cable insertion hole 66 of the operation part 64. It is guided by the outer casing 26 through the end cap 26a.

  In the state in which the case halves 68 and 69 are assembled to each other, both axial ends of the pulley shaft 34 are movably inserted into the pair of slots 71, respectively, and the pulley shaft 34 passes through the slots 71 along the longitudinal direction thereof. Thus, the pulley main body 31 is movable in the vehicle front-rear direction with respect to the pulley case 61 in the movable range. That is, between the surplus length release position where the pulley shaft 34 is disposed at one end of the slot 71 on the vehicle rear side and the surplus length generation position where the pulley shaft 34 is disposed at the other end on the vehicle front side of the slot 71. Thus, the pulley body 31 is accommodated in the pulley case 61 so as to be movable in the vehicle longitudinal direction.

  The lever member 62 is supported by the pulley case 61 via the pulley shaft 34, and a pair of shaft driving portions 63 of the lever member 62 are accommodated in the assembly grooves 72 movably. The lever member 62 has a pulley shaft at a locking position where the pulley shaft 34 is locked under the surplus length releasing position and a release position where the pulley shaft 34 is unlocked under the surplus length releasing position. It is assembled to the pulley case 61 so as to be rotatable about the axis 34.

  The pulley case 61 is inserted into the mounting holes 74a of the bracket portions 74 and 77 with the case portions 70 and 76 partially protruding to the outside of the vehicle compartment through the through holes 16a formed in the outer panel 16. The outer panel 16 is fixed to the vehicle interior side by a fixing member (not shown) such as a bolt. The case half 68 and the case half 69 are engaged with each other by an engaging claw or the like (not shown).

  FIG. 18 is an explanatory view showing the pulley body and the lever member when the lever member is in the locking position. FIG. 19 is an explanatory view showing the pulley main body and the lever member when the lever member is in the release position, and FIG. 20 is a sectional view taken along the line DD in FIG. 12 to 17 show the pulley unit 60 with the lever member 62 in the locked position.

  As shown in FIG. 18, when the lever member 62 is in the locked position, the guided portion 63 b of the lever member 62 is disposed outside the vehicle compartment with respect to the axis of the pulley shaft 34. That is, the connecting portion 63c of the lever member 62 is disposed so as to be shifted to the outside of the passenger compartment with respect to the longitudinal direction of the slot 71, and the side surfaces of the pair of shaft driving portions 63 outside the passenger compartment are provided on the case portions 70 and 76. The stopper portions 79 are respectively abutted against the stopper portions 79. As a result, the lever member 62 is prevented from being further rotated from the locked position to one side in the rotation direction (counterclockwise direction side in the figure) around the pulley shaft 34 as an axis. Also, as shown in FIG. 12, the pair of locking claws 64b of the lever member 62 are engaged with the locking holes 73 of the case halves 68 and 69, respectively.

  At this time, the pair of connecting portions 63c of the lever member 62 extend from the guided portion 63b to the vehicle rear side, and the pair of shaft support portions 63a are disposed at the end portion of the slot 71 on the vehicle rear side. ing. Further, the side surfaces of the pair of guided portions 63b on the vehicle front side are respectively abutted against the side surfaces of the guide groove portions 72a, and the lever member 62 is prevented from moving toward the vehicle front side. The pulley shaft 34 is locked to one end portion of the slot 71 on the vehicle rear side under the extra length release position by being supported by the pair of shaft support portions 63a of the lever member 62.

  Under this locking position, a pulling force by the open side cable 21 is applied to the lever member 62 via the pulley shaft 34, and the pulling force by the open side cable 21 is applied to the lever member 62 as indicated by an arrow in the figure. It acts on the shaft support part 63a of 62 toward the vehicle front side (the cable drawing direction side from the pulley main body 31). Therefore, since the connecting portion 63c of the lever member 62 is disposed to the outside of the passenger compartment with respect to the longitudinal direction of the slot 71, the lever member 62 has a pulling force due to the open cable 21 acting on the lever member 62. As a result, a moment in a direction (counterclockwise direction in the drawing) in which the lever member 62 is rotated to one side in the rotation direction from the release position to the locking position with the pulley shaft 34 as an axis is applied.

  That is, the straight line N along the longitudinal direction of the connecting portion 63c of the lever member 62 is one of the rotational directions around the pulley shaft 34 with respect to the line of action L of the pulling force acting on the lever member 62. It is inclined to the side by an angle α. For this reason, due to the pulling force of the open-side cable that acts on the lever member 62, a moment in the direction of rotating the lever member 62 to one side of the rotation direction acts on the lever member 62 with the pulley shaft 34 as the axis. The lever member 62 is held in the locking position by this moment.

  On the other hand, as shown in FIG. 19, when the lever member 62 is in the released position, the lever member 62 is rotated from the locked position to the other side in the rotational direction with the pulley shaft 34 as the center (clockwise direction in the figure). The operation portion 64 of the lever member 62 protrudes from the opening on the vehicle interior side of the pulley case 61 to the outside. At this time, the guided portion 63 b of the lever member 62 is disposed closer to the vehicle interior side than the axis of the pulley shaft 34, and the movement of the pulley shaft 34 toward the vehicle front side is not restricted by the lever member 62. For this reason, when the pulling force by the open cable 21 is applied to the lever member 62 via the pulley shaft 34 in the cable pulling direction, the lever member 62 having the pulley shaft 34 as the axis rotates. The pulley shaft 34 is moved in the slot 71 toward the front side of the vehicle.

  Next, the operation of the pulley unit 60 when routing the open cable 21 between the drive unit 23 and the roller assembly 17 of the slide door 14 will be described.

  When the other end of the open-side cable 21 drawn out from the pulley unit 60 to the slide door 14 side is connected to the roller assembly 17, the lever member 62 is rotated to the release position as in the pulley unit 24. By pulling the other end of the open side cable 21 toward the front side of the vehicle, the pulley body 31 is moved to the surplus length generation position as the lever member 62 is rotated by the pulling force of the open side cable 21. Under this surplus length generation position, a sufficient cable surplus length of the open cable 21 can be secured, and the other end of the open cable 21 can be easily locked to the roller assembly 17.

  After the opening-side cable 21 is routed, the lever member 62 is turned to one side in the turning direction with the pulley shaft 34 as an axis, and the lever member 62 is turned to the locking position. At this time, the guided portion 63b of the lever member 62 is guided along the guide groove portion 72a, so that the pulley shaft 34 is guided to the vehicle rear side along the slot 71 along with the turning operation of the lever member 62. The pulley body 31 is moved from the surplus length generation position to the surplus length release position. When the lever member 62 is in the locking position, the pulley shaft 34 is locked by the lever member 62 under the extra length releasing position. Further, the lever member 62 is engaged when the locking claw 64b and the locking hole 73 are engaged, and a moment in a direction for rotating the lever member 62 to one side in the rotation direction acts on the lever member 62. It is held in the stop position.

  Thus, in the pulley unit 60 of the present embodiment, the locking position for locking the pulley shaft 34 under the surplus length releasing position and the locking of the pulley shaft 34 under the surplus length releasing position are performed. The lever member 62 that is rotated to the release position to be released is assembled to the pulley case 61 so as to be rotatable. This lever member 62 makes it possible to hold the pulley body 31 in the excess length release position.

  Further, in the pulley unit 60 of the present embodiment, the lever member 62 is in a state where the lever member 62 is against the acting line L of the pulling force caused by the open cable 21 applied to the lever member 62 when the lever member 62 is in the locked position. By displacing the connecting portion 63c to one side in the rotation direction, a moment in a direction in which the lever member 62 is rotated to one side in the rotation direction by the pulling force by the open cable 21 applied to the lever member 62 is generated. The lever member 62 is made to act. As a result, the lever member 62 can be held in the locking position without providing a fixing member such as a bolt, and the operation of holding the pulley body 31 in the excess length releasing position becomes easy and the number of parts is reduced. Thus, the cost and weight of the pulley unit 60 can be reduced.

  21A and 21B are schematic views showing a pulley unit according to still another embodiment of the present invention. In FIGS. 21A and 21B, members similar to those described above are given the same reference numerals, and descriptions thereof are omitted.

  In the rear pulley unit 80, the lever member 81 has the same shape as the lever member 62 described above, and is guided along a guide groove portion (guide portion) 82 formed in a pulley case (not shown). A portion 83; a shaft support portion 84 that is rotatably supported around the pulley shaft 34; and a connecting portion 85 that connects the guided portion 83 and the shaft support portion 84. The pulley body 31 is disposed horizontally with the axial direction of the pulley shaft 34 directed in the vehicle vertical direction, and the open-side cable 21 faces the slide door 14 side and the drive unit 23 side from the pulley body 31 to the front of the vehicle. Pulled out to the side.

  The pulley case is formed with a slot (long hole) 86 for movably supporting both axial ends of the pulley shaft 34, and the slot 86 extends in the vehicle front-rear direction along the direction of drawing the cable from the pulley body 31. It extends to. The guide groove portion 82 is formed on the vehicle rear side of the slot 86, that is, on the opposite side to the cable pulling direction from the pulley body 31. The guide groove portion 82 is formed to bend toward the vehicle rear side toward the vehicle compartment outer side, and at the end portion on one side of the rotation direction of the guide groove portion 82 (vehicle compartment outer side), the vehicle front side, that is, the cable lead-out. An engaging groove portion 82a protruding toward the direction side is formed as an engaging portion.

  In this pulley case, both ends of the pulley shaft 34 in the axial direction are inserted into a pair of slots 86 so as to be movable, and the pulley shaft 34 can be moved within the slot 86 along the longitudinal direction thereof. The main body 31 is movable in the vehicle front-rear direction with respect to the pulley case. That is, between the surplus length release position where the pulley shaft 34 is disposed at one end of the slot 86 on the vehicle rear side and the surplus length generation position where the pulley shaft 34 is disposed at the other end on the vehicle front side of the slot 86. Thus, the pulley body 31 is accommodated in the pulley case so as to be movable in the vehicle longitudinal direction.

  The lever member 81 is supported by the pulley case via the pulley shaft 34. The lever member 81 has a pulley shaft at a locking position where the pulley shaft 34 is locked under the surplus length releasing position and a release position where the pulley shaft 34 is unlocked under the surplus length releasing position. It is assembled to a pulley case so as to be rotatable about 34 as an axis.

  21A shows the pulley main body and the lever member when the lever member is in the locking position, and FIG. 21B shows the pulley main body and the lever member when the lever member is in the release position. ing.

  As shown in FIG. 21A, when the lever member 81 is in the locking position, the guided portion 83 of the lever member 81 is engaged with the engaging groove portion 82a of the guide groove portion 82. That is, the guided portion 83 is fitted into the engaging groove portion 82a that is recessed toward the cable drawing direction. Thereby, when the pulling force by the open cable 21 is applied to the lever member 81 via the pulley shaft 34 in the cable pulling direction, the load in the direction in which the guided portion 83 engages with the engaging groove portion 82a is applied to the lever. Since it is engaged with the member 81, the lever member 81 is not rotated toward the other side in the rotation direction (counterclockwise direction side in the figure), and the lever member 81 is held at the locking position. ing. Further, when the guided portion 83 of the lever member 81 is abutted against the end of the guide groove portion 82 on the outer side of the passenger compartment, the lever member 81 is further rotated around the pulley shaft 34 from the locking position. It is prevented from rotating to one side (clockwise direction in the figure).

  On the other hand, as shown in FIG. 21B, when the lever member 81 is in the release position, the lever member 81 is rotated from the locking position to the other side in the rotation direction with the pulley shaft 34 as an axis. It is arranged at the position. At this time, the guided portion 83 of the lever member 81 is not engaged with the engaging groove portion 82 a of the guide groove portion 82, and the movement of the pulley shaft 34 toward the vehicle front side is not restricted by the lever member 81. For this reason, when the pulling force by the open cable 21 is applied to the lever member 81 through the pulley shaft 34 in the cable pulling direction, the lever member 81 having the pulley shaft 34 as the axis rotates. The pulley shaft 34 is moved in the slot 86 toward the vehicle front side.

  Next, the operation of the pulley unit 80 when routing the open cable 21 between the drive unit 23 and the roller assembly 17 of the slide door 14 will be described.

  When the other end of the open-side cable 21 drawn out from the pulley unit 80 to the slide door 14 side is connected to the roller assembly 17, the lever member 81 is rotated to the release position as in the pulley unit 24. Then, by pulling the other end of the open side cable 21 toward the front side of the vehicle, the pulley body 31 is moved to the surplus length generation position as the lever member 81 is rotated by the pulling force of the open side cable 21. Under this surplus length generation position, a sufficient cable surplus length of the open cable 21 can be secured, and the other end of the open cable 21 can be easily locked to the roller assembly 17.

  After the opening side cable 21 is routed, the lever member 81 is rotated to one side in the rotation direction with the pulley shaft 34 as an axis, and the lever member 81 is rotated to the locking position. At this time, the guided portion 83 of the lever member 81 is guided along the guide groove portion 82, whereby the pulley shaft 34 is guided to the vehicle rear side along the slot 86 along with the turning operation of the lever member 81, The pulley body 31 is moved from the surplus length generation position to the surplus length release position. When the lever member 81 reaches the locking position, the pulley shaft 34 is locked by the lever member 81 under the excess length releasing position. Further, the lever member 81 is held at the locking position when a load in a direction in which the guided portion 83 is engaged with the engaging groove portion 82 a acts on the lever member 81.

  Thus, in the pulley unit 80 of the present embodiment, the locking position for locking the pulley shaft 34 under the surplus length releasing position and the locking of the pulley shaft 34 under the surplus length releasing position are performed.
