JP 2001-82027 A

  In the window regulator of Patent Document 1, a glass carrier (slider base) is configured by combining a synthetic resin main body and a metal reinforcing plate. When the wire is pulled, the wire end storage portion formed in the main body is formed. The end surface of the wire end (the end surface on the side to which the wire is connected) comes into contact with the inner surface. The reinforcing plate is provided with a wire end retaining piece to be inserted in the vicinity of the wire end housing portion of the main body, and the wire end retaining piece disperses stress from the main body to the reinforcing plate. As another type different from Patent Document 1, there is also known a type of window regulator in which the end surface of the wire end is in direct contact with the wire end retaining piece of the reinforcing plate. In such a conventional window regulator, the overall rigidity of the main body is improved by the reinforcing plate, but the local load applied from the wire end to the wire end retaining piece is received by the synthetic resin main body. The load on the main body tends to be large. Further, when the load is large, the wire end retaining piece may be deformed.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a wire-type window regulator with improved load resistance in a glass carrier when a wire is pulled.

  The present invention includes a glass carrier that supports a window glass and is supported so as to be movable in the ascending / descending direction of the window glass, and a pair of wires that have a wire end at one end and provide a pulling force in the ascending / descending direction to the glass carrier. The provided window regulator has the following characteristics. A glass carrier is comprised by the resin-made main body member and the plate-shaped metal support member which overlaps with a main body member. The main body member includes a wire end locking portion capable of abutting an end surface on the wire connecting side of each wire end, and a pressed portion positioned on the other end side of the wire from the wire end locking portion. Have. The support member is cut and raised to provide a wire end retaining piece. The wire end retaining piece is inserted between the wire end locking portion and the pressed portion of the main body member, and can come into contact with the pressed portion in the direction in which the end surface of the wire end contacts the wire end locking portion. It becomes. The support member is further formed with an engagement hole by cutting and raising the wire end retaining piece. The main body member is provided with a protruding portion that is provided on the other end side of the wire with respect to the pressed portion, and that contacts the edge of the engagement hole in the direction in which the end surface of the wire end contacts the wire end locking portion. .

  It is preferable that at least a part of the protruding portion is located within a range of a width obtained by extending the wire end locking portion to the other end side of the wire.

  The main body member has a crossing part that crosses and supports a pair of wires, and the main body member and the support member are fitted to each other at different positions in the wind glass ascending / descending direction across the crossing part. It is preferable to provide a fitting part.

  As a different form of the window regulator of the present invention, an end face of the wire end on the side to which the wire is connected may be directly brought into contact with a wire end retaining piece formed by cutting and raising the support member. The main body member has a pressed portion that is positioned on the other end side of the wire with respect to the wire end retaining piece and can be brought into contact with the wire end retaining piece. Then, an engagement hole is formed in the support member by cutting and raising the wire end retaining piece, and a protrusion that can contact the edge of the engagement hole is provided on the main body member. The protruding portion is positioned on the other end side of the wire with respect to the pressed portion, and contacts the edge of the engagement hole in a direction in which the end surface of the wire end contacts the wire end retaining piece.

  According to the above-described window regulator of the present invention, when the wire is pulled, the load input to the pressed portion of the resin main body member from the wire end retaining piece of the support member is applied to the protrusion of the main body member and the support member. The load applied to the glass carrier when the wire is pulled by changing the load applied between the pressed part and the projecting part of the main body member into a compressive load by receiving at the contact part with the edge of the engagement hole Can be improved. Moreover, the deformation | transformation of a wire end retaining piece can be suppressed because the part between the to-be-pressed part and protrusion part in a main body member stretches.

  The support member 50 includes a flat cover portion 51 and glass attachment portions 52 and 53 located on both sides of the cover portion 51. The glass attachment portion 52 and the glass attachment portion 53 are fixed to the window glass using fastening means (not shown). The cover portion 51 is formed with a pair of first sandwiching pieces 54 and 55 and a pair of second sandwiching pieces 56 and 57. The first sandwiching pieces 54 and 55 are arranged separately on the upper end side and the lower end side of the cover part 51, and are arranged at different positions in the width direction of the cover part 51. Similarly, the second sandwiching pieces 56 and 57 are arranged separately on the upper end side and the lower end side of the cover part 51 and are arranged at different positions in the width direction of the cover part 51. More specifically, the first clamping piece 54 and the second clamping piece 56 are provided on the upper end side of the cover portion 51 and have a positional relationship facing the width direction. The 1st clamping piece 55 and the 2nd clamping piece 57 are provided in the lower end side of the cover part 51, and have the positional relationship which opposes the width direction. In addition, the first sandwiching piece 54 and the second sandwiching piece 57 are provided at a position close to the glass attachment portion 52 in the width direction of the cover portion 51, and the first sandwiching piece 55 and the second sandwiching piece 56 are arranged in the width of the cover portion 51. It is provided at a position close to the glass attachment portion 53 in the direction. Accordingly, the straight line connecting the first holding pieces 54 and 55 and the straight line connecting the second holding pieces 56 and 57 intersect each other in a state in which the support member 50 is viewed in plan as shown in FIGS. Both the first clamping pieces 54 and 55 and the second clamping pieces 56 and 57 are formed as a part of a bent portion bent toward the vehicle inner side with respect to the cover portion 51. About the 1st clamping pieces 54 and 55 and the 2nd clamping pieces 56, it is the inner side of the cover part 51 (1st clamping part 54a, 55a, 56a) with respect to the base end bending parts 54a, 55a, and 56a bent at substantially right angle with respect to the cover part 51. The piece 54 and the second holding piece 56 are bent at a substantially right angle toward the lower side and the first holding piece 55 on the upper side. On the other hand, the second clamping piece 57 is bent at a substantially right angle toward the outer side (lower side) of the cover part 51 with respect to the base end bending part 57a bent at a substantially right angle with respect to the cover part 51. It has become.

  The support member 50 is further formed with a pair of wire end retaining pieces 58 and 59 that are paired in different positions in the vertical direction. As shown in FIG. 12, each wire end retaining piece 58, 59 is formed by cutting and raising a part of the cover portion 51 toward the inside of the vehicle, and has a bifurcated shape having wire insertion grooves 58a, 59a at the tip portions thereof. It is a protrusion part. Engagement holes 60 and 61 are formed in the cover portion 51 by cutting and raising when the wire end retaining pieces 58 and 59 are formed. The engagement hole 60 and the engagement hole 61 are holes that are inclined so as to decrease the vertical interval between the support member 50 in the width direction from the glass attachment portion 53 side to the glass attachment portion 52 side. As shown in FIGS. 11 to 13, fitting protrusions 62 and 63 (fitting portions) are formed in the vicinity of the engagement holes 60 and 61. The fitting protrusions 62 and 63 are cylindrical protrusions, and protrude toward the vehicle interior in the same manner as the wire end retaining pieces 58 and 59.

  Before the main body member 30 and the support member 50 are combined, the wire 15 and the wire 16 are assembled to the main body member 30. As shown in FIG. 7, a wire end 70 having a diameter larger than that of the wire 15 is provided at the end of the wire 15. As described above, the wire guide groove 33 and the wire end storage portion 35 are opened to the outer surface of the main body member 30, and the wire 15 and the wire end 70 are opened to the wire guide groove 33 from the opened vehicle outer side. It is inserted into the wire end storage part 35. As shown in FIG. 7, a compression spring 71 is inserted between the flange portion of the wire end 70 inserted into the wire end storage portion 35 and the contact surface 35 a. The wire 16 is inserted into the wire guide groove 34 in the same manner as the wire 15. A large-diameter wire end 72 (a part of which is shown in FIG. 5) is provided at the end of the wire guide groove 34, and the wire end 72 is inserted into the wire end storage portion 36. A compression spring (not shown) is inserted between the flange portion of the wire end 72 and the contact surface 36a. The wire 15 inserted into the wire guide groove 33 and the wire 16 inserted into the wire guide groove 34 pass through the intersection 45 where the wire guide groove 33 and the wire guide groove 34 intersect, respectively, and the wire introduction port 33a and the wire The main body member 30 is pulled out through the introduction port 34a. Since the positions of the wire guide groove 33 and the wire guide groove 34 in the intersecting portion 45 are different in the thickness direction of the main body member 30, the wire 15 and the wire 16 do not interfere with each other at the intersecting portion 45.

  When the wires 15 and 16 are assembled as described above, the contact surfaces 35a and 36a in the wire end storage portions 35 and 36 corresponding to the wire end 70 and the wire end 72, respectively, when the wires 15 and 16 are not tensioned. It is not pressed to the side. The retaining protrusion 35b and the retaining protrusion 36b prevent the wire ends 70 and 72 from falling off from the wire end storage portions 35 and 36 in this state.

  The support member 50 is configured so that the first clamping pieces 54 and 55, the second clamping pieces 56 and 57, the wire end retaining pieces 58 and 59, and the fitting protrusions 62 and 63 protrude toward the vehicle interior side. The cover 51 is put on the vehicle from the outside and assembled. As shown in FIGS. 4 and 6, in a state where the support member 50 is assembled to the main body member 30, both sides of the guide portion 31 of the main body member 30 by the first holding piece 54 and the second holding piece 56 provided on the support member 50. The surface 31 b is clamped, and the both side surfaces 32 b of the guide portion 32 are clamped by the first clamping piece 55 and the second clamping piece 57. The relative movement of the main body member 30 and the support member 50 in the width direction is restricted by these clamping. Further, the relative movement of the main body member 30 and the support member 50 in the vertical direction is restricted by sandwiching the upper end and the lower end of the main body member 30 by the base end bending portions 54a, 55a, 56a and 57a. At this time, as shown in FIG. 6, the retaining protrusion 41 of the main body member 30 engages with the first sandwiching piece 54 of the support member 50, and the retaining protrusion 42 of the main body member 30 is engaged with the second sandwiching piece 57 of the support member 50. The main body member 30 and the support member 50 are coupled so as not to be separated in the thickness direction of the slider base 14. More specifically, when the support member 50 is assembled to the main body member 30, if the first sandwiching piece 54 comes into contact with the retaining protrusion 41, the first sandwiching piece 54 is elastically deformed toward the glass mounting portion 52 side. When the second clamping piece 57 comes into contact with the retaining projection 42 and gets over the retaining projection 41, the second clamping piece 57 is elastically deformed toward the glass mounting portion 52 and climbs over the retaining projection 42. Then, when the first clamping piece 54 and the second clamping piece 57 return from elastic deformation after overcoming the retaining projection 41 and the retaining projection 42, respectively, the engaged state shown in FIG. 6 is obtained.

  When the support member 50 is assembled to the main body member 30, the wire end retaining piece 58 is inserted into the insertion groove 37, and the wire end retaining piece 59 is inserted into the insertion groove 38. The wire end retaining piece 58 is inserted on the extension of the wire 15, but does not interfere with the wire 15 by inserting the wire 15 into the wire insertion groove 58 a. Similarly, the wire end retaining piece 59 is inserted on the extension of the wire 16, but does not interfere with the wire 16 by inserting the wire 16 into the wire insertion groove 59a. Further, when the support member 50 is assembled to the main body member 30, the protrusion 39 is inserted into the engagement hole 60 and the protrusion 40 is inserted into the engagement hole 61 as shown in FIG. 6. The protrusion 39 abuts against a portion of the inner edge of the engagement hole 60 opposite to the wire end retaining piece 58. The protrusion 40 abuts against a portion of the inner edge of the engagement hole 61 opposite to the wire end retaining piece 59. That is, the protrusion 39 abuts against the inner edge of the engagement hole 60 in the same direction as the end surface of the wire end 70 (the end surface on the side to which the wire 15 is connected) abuts the abutment surface 35a. 40 abuts against the inner edge of the engagement hole 61 in the same direction as the end surface of the wire end 72 (the end surface to which the wire 16 is connected) abuts the abutment surface 36a. Further, in a state where the support member 50 is assembled to the main body member 30, the fitting protrusion 62 and the fitting hole 46 are fitted, and the fitting protrusion 63 and the fitting hole 47 are fitted.

  The wire 15 having the wire end 70 at one end connected to the slider base 14 configured as described above extends upward along the guide rail 11, is guided by the guide pulley 17, and is inserted into the guide tube 21. Then, it is wound around a winding drum in the drum housing 20. A wire 16 having a wire end 72 at one end connected to the window regulator 10 extends downward along the guide rail 11, is guided by the guide piece 18 and is inserted into the guide tube 22, and is wound in the drum housing 20. It is wound around a drum. As the winding amount of each wire 15, 16 around the winding drum is increased, the tension of each wire 15, 16 is increased. When the tension is increased, the wire ends 70 and 72 of the wires 15 and 16 (the end surface of the wire end 70 to which the wire 15 is connected, the end surface of the wire end 72 to which the wire 16 is connected) are formed. The compression springs 71 (the compression springs fitted to the wire ends 72 are not shown) which are pressed against the contact surfaces 35a, 36a of the corresponding wire end storage portions 35, 36 and fit to the wire ends 70, 72 are compressed and deformed. FIG. 7 shows a state where the wire end 70 is pressed against the contact surface 35a, and the wire end 72 is also pressed against the contact surface 36a in the same manner.

  1 to 3 show a completed state of the window regulator 10 in which the wiring of the wire 15 and the wire 16 is completed and the guide portions 31 and 32 of the slider base 14 are slidably supported with respect to the guide rail 11. is there. When the winding drum in the drum housing 20 is rotated in this completed state, one and the other of the wire 15 and the wire 16 are pulled and relaxed according to the rotation direction. In the pulled wires 15 and 16, the wire ends 70 and 72 transmit force to the corresponding contact surfaces 35 a and 36 a of the wire end storage portions 35 and 36. Since the movement of the wire ends 70 and 72 to the other end side (winding drum side) of the wires 15 and 16 with respect to the slider base 14 is restricted by contact with the contact surfaces 35a and 36a, A force for moving the guide rail 11 in the longitudinal direction acts on the slider base 14 from the wires 15 and 16 in the force applying portions F1 and F2 (FIG. 10). The force applying portion F1 is a portion where an upward pulling force acts on the contact portion of the slider base 14 from the wire 15 when the wire 15 is pulled, and the force applying portion F2 is a portion where the wire 16 is pulled. This is a place where a downward traction force acts on the contact position of the slider base 14 from the wire 16. The loose wires 15 and 16 are loosened by being pressed in a direction in which the wire ends 70 and 72 are separated from the contact surfaces 35a and 36a by the force of the compression spring 71 (the compression spring acting on the wire end 72 is not shown). Removed.

  FIGS. 14 to 16 collectively show the relationship between the slider base 14 and the guide pulley 17 at the top dead center of the window glass and the relationship between the slider base 14 and the guide piece 18 at the bottom dead center of the window glass. is there. As can be seen from these drawings, the guide portion 31 and the guide portion 32 in the slider base 14 are arranged at different positions from the guide pulley 17 and the guide piece 18 in the width direction of the guide rail 11. Can move without interfering to the side of the guide pulley 17 at the top dead center of the window glass, and can move without interfering to the side of the guide piece 18 at the bottom dead center of the window glass. That is, since almost the entire length of the guide rail 11 in the longitudinal direction becomes the movable range of the slider base 14, the window regulator 10 can increase the amount of movement of the window glass (the stroke amount of the slider base 14) while being small.

  In the window regulator 10 configured as described above, when the slider base 14 is moved in the longitudinal direction of the guide rail 11 by pulling the wires 15, 16, the guide portions 31, which are slidably fitted to the guide rail 11, 32 and the applied force portions F1 and F2 to which the pulling force in the up-and-down direction acts from the wires 15 and 16 are different in the width direction of the guide rail 11, so that the slider base 14 receives the pulling force on the side receiving the pulling force. The moment of rotation around the parts F1 and F2 works. Here, in the slider base 14, guide portions 31 and 32 are located between the force applying portions F 1 and F 2 and the wire end storage portions 35 and 36 in the width direction of the guide rail 11. Therefore, the distance in the width direction between the force applying portions F1, F2 and the guide portions 31, 32 can be reduced without being affected by the arrangement space of the wire end storage portions 35, 36 and the wire ends 70, 72, and the moment is suppressed. be able to. By reducing the moment acting on the slider base 14, wear of the guide portions 31 and 32 with respect to the guide rail 11 can be reduced, and the operating efficiency at the time of raising and lowering the window glass can be increased.

  In the slider base 14, the force applying portions F 1 and F 2 and the wire end storage portions 35 and 36 (particularly the contact surfaces 35 a and 36 a) are positioned between the guide portion 31 and the guide portion 32 in the vertical direction. According to this arrangement, the rotation of the slider base 14 relative to the guide rail 11 can be suppressed by the guide portion 31 and the guide portion 32 having a large vertical interval, and the support connection structure (wires) for the wires 15 and 16 relative to the slider base 14 The abutment portions F1 and F2 that receive the force in the up-and-down direction from 15 and 16 and the contact surfaces 35a and 36a of the wire end storage portions 35 and 36 that lock the wire ends 70 and 72 are provided between the guide portion 31 and the guide portion 32. The slider base 14 can be configured compactly in the vertical direction by concentrating in the vertical range therebetween.

  Further, in the slider base 14 of the window regulator 10, the metal support member 50 is fixed to the window glass, and the synthetic resin main body member 30 is not fixed directly to the window glass, but the support member 50 is fixed. It is indirectly combined with the wind glass via. Therefore, the force acting on the window glass can be received by the support member 50 having high rigidity, and concentration of stress on the main body member 30 can be prevented. Since the main body member 30 is a part responsible for sliding with respect to the guide rail 11 and connecting the wires 15 and 16, the performance of the window regulator 10 can be maintained by preventing bending and deformation due to stress concentration on the main body member 30. In particular, the guide portions 31 and 32 of the main body member 30 are sandwiched in the width direction by the pair of first sandwiching pieces 54 and 55 and the pair of second sandwiching pieces 56 and 57 provided on the support member 50, so that FIG. The rotational rigidity of the slider base 14 with respect to the inclination of the window glass in the left-right direction of FIG. 2 (the front-rear direction of the vehicle when the window regulator 10 is attached to the side door of the vehicle) can be increased.

  For example, when a force is applied to the support member 50 from the window glass to rotate in the clockwise direction in FIG. 1 (counterclockwise in FIG. 2), the first one located diagonally across the guide portions 31 and 32. A pressing force is applied to the guide portions 31 and 32 from the sandwiching pieces 54 and 55. On the other hand, when a force to rotate counterclockwise in FIG. 1 (clockwise in FIG. 2) acts on the support member 50 from the window glass, the second is located diagonally across the guide portions 31 and 32. 2 A pressing force is applied to the guide portions 31 and 32 from the sandwiching pieces 56 and 57. Since the guide portions 31 and 32 are at positions separated in the vertical direction (the upper end and the lower end of the slider base 14), the body member 30 is unlikely to be locally bent or deformed when receiving such a pressing force, and the slider base 14 Can adversely affect the operation performance. Furthermore, since the side wall 11b and the flange 11c of the guide rail 11 are fitted in the groove portions 31a and 32a of the guide portions 31 and 32 with the slider base 14 supported by the guide rail 11, the first sandwiching pieces 54 and 55 are fitted. When the pressing force is applied to the guide portions 31 and 32 from the second sandwiching pieces 56 and 57, the guide rail 11 functions as a reinforcing material for the guide portions 31 and 32 and high rigidity can be obtained.

  The guide portions 31 and 32 of the main body member 30 are slidably fitted to the guide rail 11 and are sandwiched between the first sandwiching pieces 54 and 55 and the second sandwiching pieces 56 and 57. Further, the retaining protrusions 41 and 42 provided on the guide portions 31 and 32 of the main body member 30 are in the thickness direction of the slider base 14 due to the engagement between the first sandwiching piece 54 and the second sandwiching piece 57 of the support member 50. It functions as a retaining portion that regulates the separation of the main body member 30 and the support member 50 from each other. As described above, by providing the guide portions 31 and 32 and the sandwiching pieces 54, 55, 56, and 57 with a composite function, the configuration of the slider base 14 can be simplified.

  As shown in FIGS. 14 and 16, the base end bending portion 54a of the first clamping piece 54 is different in position in the width direction from the guide pulley 17, and the slider base 14 is moved to the top dead center of the window glass. Sometimes the base end bending portion 54a and the guide pulley 17 do not interfere with each other. On the other hand, the base end bending portion 57 a of the second sandwiching piece 57 is at a position in the width direction overlapping with a part of the guide piece 18. Therefore, with respect to the second sandwiching piece 57, the bending direction from the proximal end bending portion 57 a is reversed to that of the first sandwiching piece 55, and the direction away from the cover portion 51 toward the distal end from the proximal end bending portion 57 a (downward). Protruding. Accordingly, the position of the base end bending portion 57a is set above the base end bending portion 55a, and the downward stroke of the slider base 14 can be increased without causing the base end bending portion 57a and the guide piece 18 to interfere with each other. It is possible.

  The window regulator 10 of the present embodiment includes two sets of first sandwiching pieces 54 and 55 and second sandwiching pieces 56 and 57. With this configuration, rotational rigidity is obtained with respect to any inclination of the window glass. Although it is preferable because it can be increased, it is also possible to adopt a configuration including only one set of clamping pieces. For example, when the improvement of the rotational rigidity of the slider base 14 with respect to the rotation of the window glass in the clockwise direction in FIG. 1 (counterclockwise in FIG. 2) is mainly required, the second clamping pieces 56 and 57 are omitted. Only one clamping piece 54, 55 may be provided.

  When the wind drum is rotated by the window regulator 10 to rotate the winding drum and pull the wires 15 and 16, the corresponding contact surfaces 35 a and 36 a from the wire ends 70 and 72 of the pulled wires 15 and 16. The tensile force works against. For example, the tensile force from the wire end 70 to the contact surface 35a is a load in a direction toward the other end of the wire 15 along the wire guide groove 33 with respect to the main body member 30 on which the contact surface 35a is formed. Acts as More specifically, the load applied to the contact surface 35 a of the main body member 30 is received by the wire end retaining piece 58 of the support member 50, and the wire end retaining piece 58 presses the pressed surface 43 to load the main body member 30. Act. As shown in FIGS. 6 and 7, a projecting portion 39 is provided in the direction of the load, and the projecting portion 39 is pressed against the inner edge of the engagement hole 60 in response to the load applied to the main body member 30. Then, a compressive load acts on the main body member 30 between the contact portion between the wire end retaining piece 58 and the pressed surface 43 and the contact portion between the protruding portion 39 and the inner edge portion of the engagement hole 60. Similarly, the tensile force from the wire end 72 to the contact surface 36 a acts on the main body member 30 as a load in the direction toward the other end of the wire 16 along the wire guide groove 34. More specifically, the load applied to the contact surface 36 a of the main body member 30 is received by the wire end retaining piece 59 of the support member 50, and the wire end retaining piece 59 presses the pressed surface 44 to load the main body member 30. Act. As shown in FIG. 6, a projecting portion 40 is provided in the acting direction of the load, and the projecting portion 40 is pressed against the inner edge of the engagement hole 61 in response to the load on the main body member 30. Then, a compressive load acts on the main body member 30 between the contact portion between the wire end retaining piece 59 and the pressed surface 44 and the contact portion between the protruding portion 40 and the inner edge portion of the engagement hole 61. Since the synthetic resin main body member 30 is superior in load resistance against a compressive load as compared with a tensile load or a shear load, there is an advantage that the main body member 30 is hardly damaged or deformed even when a strong load is applied.

  The main body member 30 and the support member 50 are further provided with a fitting portion including a fitting hole 46 and a fitting protrusion 62 and a fitting portion including a fitting hole 47 and a fitting protrusion 63 at the upper and lower positions sandwiching the intersecting portion 45. Have. Thus, by fitting the main body member 30 and the support member 50 at the upper and lower positions sandwiching the intersection 45, the wires 15 and 16 routed through the wire introduction ports 33a and 34a of the wire guide grooves 33 and 34 are moved in the vertical direction. The stress applied to the main body member 30 can be distributed to the support member 50 when the wire 15 is pulled upward (when the wire 15 is pulled upward and when the wire 16 is pulled downward). Thereby, the load resistance of the slider base 14 is further improved.

  The protrusions 39 and 40 are protrusions that protrude from the surface of the main body member 30 facing the vehicle exterior side, and can be easily formed when the main body member 30 is molded. In particular, in the main body member 30, as can be seen from FIG. 10, the wire guide grooves 33, 34, the wire end storage portions 35, 36, the protruding portions 39, 40, and the fitting holes 46, 47 are all provided on the surface facing the vehicle exterior. These parts can be formed at a time by a mold that is released toward the outside of the vehicle. Further, the engagement holes 60 and 61 can be formed at the same time when the wire end retaining pieces 58 and 59 are cut and raised in the support member 50. Therefore, the protrusions 39 and 40 and the engagement holes 60 and 61 are excellent in productivity.

  Note that the concave and convex relationship is reversed from that of the illustrated embodiment, and concave portions corresponding to the engagement holes 60 and 61 are provided on the main body member 30 side, and convex portions corresponding to the protruding portions 39 and 40 are provided on the support member 50 side. The configuration can also be adopted. Similarly, a configuration in which convex portions corresponding to the fitting protrusions 62 and 63 are provided on the main body member 30 side and concave portions corresponding to the fitting holes 46 and 47 are provided on the support member 50 side may be employed.

  As described above, the main body member 30 and the support member 50 include the insertion grooves 37 and 38 and the wire end retaining pieces 58 and 59 in addition to the engaging portions including the protruding portions 39 and 40 and the engaging holes 60 and 61. have. The insertion groove 37 and the wire end retaining piece 58 are located closer to the wire end storage portion 35 than the protruding portion 39 and the engaging hole 60, and the insertion groove 38 and the wire end retaining piece 59 are disposed to the protruding portion. 40 and the engagement hole 61 are located closer to the wire end storage portion 36. A tensile force applied to the contact surface 35a from the wire end 70 is received by the wire end retaining piece 58 in the insertion groove 37, and a tensile force applied to the contact surface 36a from the wire end 72 is removed from the wire end 38 in the insertion groove 38. The stress applied to the main body member 30 from the wire ends 70 and 72 is received via the wire end retaining pieces 58 and 59 together with the engaging portions composed of the protruding portions 39 and 40 and the engaging holes 60 and 61 described above. The support member 50 can be dispersed. The width of each of the wire end retaining pieces 58 and 59 when the slider base 14 is viewed in plan as shown in FIG. 6 is wider than the width of the portion where the wire ends 70 and 72 are in contact with the contact surfaces 35a and 36a. High stress dispersion effect. In addition, the portion between the pressed surfaces 43 and 44 and the projecting portions 39 and 40 in the main body member 30 is configured to stretch against the compressive load, thereby preventing the wire end from protruding from the support member 50 in a cantilevered manner. An effect of suppressing deformation of the pieces 58 and 59 is also obtained. Accordingly, a relationship is established in which the main body member 30 and the support member 50 increase the mutual strength.

  4, 6, and 10, the protrusion 39 has a width range in which the wire end storage portion 35 and the wire end retaining piece 58 are extended along the wire guide groove 33 to the other end side of the wire 15. Located in. Similarly, the protruding portion 40 is located within a width range in which the wire end storage portion 36 and the wire end retaining piece 59 are extended along the wire guide groove 34 to the other end side of the wire 16. In other words, the entire contact portion between the protrusion 39 and the engagement hole 60 is located on an extension of the direction of application of the load applied from the wire end 70 to the main body member 30, and the contact between the protrusion 40 and the engagement hole 61. The entire contact portion is located on the extension of the acting direction of the load applied from the wire end 72 to the main body member 30. By arranging in this way, the above-described stress dispersion effect by the protrusions 39 and 40 and the engagement holes 60 and 61 can be enhanced.

  However, unlike the present embodiment, a part of the contact portion between the protruding portion 39 and the engagement hole 60 is arranged so as to be out of the range of the width obtained by extending the wire end storage portion 35 and the wire end retaining piece 58, or Even in the arrangement where a part of the contact portion between the protrusion 40 and the engagement hole 61 deviates from the range of the width obtained by extending the wire end storage portion 36 and the wire end retaining piece 59, the slider base 14 A predetermined effect can be obtained with respect to improvement in load resistance.

  FIG. 17 shows a different embodiment of the slider base 14. In this embodiment, the end surface of the wire end 70 to which the wire 15 is connected is brought into contact with the support member 50 instead of the main body member 30. More specifically, a wire end retaining piece 158 is formed on the support member 50 by cutting and raising. When the wire 15 is pulled, the end surface of the wire end 70 comes into contact with the wire end retaining piece 158. The main body member 30 is formed with a pressed surface 143 (a pressed portion) with which a surface of the wire end retaining piece 158 opposite to the side with which the wire end 70 abuts is formed. A load applied to the stopper piece 158 also acts on the pressed surface 143. As in the previous embodiment, the protruding portion 39 is in contact with the inner edge portion of the engagement hole 61 at the tip of the direction of application of the load, the contact portion between the wire end retaining piece 158 and the pressed surface 143, and the protruding portion. A compression load acts on the main body member 30 between the portion 39 and the contact portion of the inner edge portion of the engagement hole 60. Thereby, the same effect as the previous embodiment can be obtained. Although not shown, a similar load receiving structure is provided for the other wire 16.

  Although the present invention has been described based on the illustrated embodiment, the present invention is not limited to the illustrated embodiment, and can be improved or modified without departing from the gist of the invention.

  For example, the window regulator 10 of the illustrated embodiment is a type in which the slider base 14 is slidably supported with respect to the guide rail 11, but the present invention can also be applied to a type of window regulator that does not include the guide rail. It is. In other words, any window regulator having at least a wire and a glass carrier that is pulled by the wire and moves in the up-and-down direction of the window glass is applicable.

  The slider base 14 of the illustrated embodiment includes two wire end storage portions 35 and 36 for individually locking the wire ends 70 and 72 of the wires 15 and 16, but the two wire ends 70 and 72 are combined. It is also possible to use a common wire end storage portion to be locked.

Further, as described above, a modified example in which the unevenness of the protrusions 39 and 40 and the engagement holes 60 and 61 are reversed, and a part of the fitting portion between the protrusions 39 and 40 and the engagement holes 60 and 61 are shown. It is also possible to adopt a modification in which the wire end storage portions 35, 36 and the wire end retaining pieces 58, 59 are positioned outside the extended width range.
It is also possible.
