The pulley bracket 30 is a molded product made of a material such as synthetic resin, and is formed by using a metal mold (upper mold) 45 and a metal mold (lower mold) 46 shown in FIG. The eighth figure shows the configuration of the metal mold in the portion of the pulley bracket 30 where the outer tube insertion portion 32 is formed. The metal mold 45 and the metal mold 46 are changeable from each other in the direction along the axis 19x of the pulley support shaft 19, and are accessible to positions where the control faces 47, 48 of each other abut. Further, it is also possible to adopt a form in which one of the metal mold 45 and the metal mold 46 is movable, and the other is formed into a fixed type that does not move, or both of them form a movable movable type. Since the pulley accommodating portion 31 of the pulley bracket 30 is a recess opened in the direction along the axis 19x of the pulley support shaft 19, the metal can be relatively moved by the direction along the axis 19x (the lower direction in the eighth diagram). The mold 45 is formed with a metal mold 46. The accommodating portion opening 31a of the pulley accommodating portion 31 is formed by a protruding portion (not shown) provided in the mold 45.

Similarly to the pulley housing portion 31, the outer tube insertion portion 32 may be formed only by the metal mold 45 and the metal mold 46. As shown in the eighth figure, the metal mold 45 and the metal mold 46 have concave portions 49, 50 opposed to each other. The metal mold 45 has a projection 51 projecting from the bottom of the recess 49, and the metal mold 46 has a projection 52 projecting from the bottom of the recess 50. The projection 52 is formed in a double-strand shape having an intermediate recess 53 recessed from the front end to a predetermined depth, and the projection 51 can be inserted into the intermediate recess 53. The amount of protrusion of the protrusion 51 is smaller than the depth of the intermediate recess 53. When the protrusion 51 is inserted into the deepest state (the state in which the regulating surfaces 47, 48 abut), a gap is formed between the front end of the protrusion 51 and the bottom of the intermediate recess 53. When the pulley bracket 30 is formed, when the mold 45 and the mold 46 are brought close to the control surface 47 and the control surface 48, the concave portion 49 and the inner surface of the concave portion 50 form the tube insertion portion 32 including the reinforcing rib 42. Outer shape. In addition, The mold 51 is inserted into the intermediate recess 53 by the proximity of the metal mold 45 and the mold 46, and the projection 51 and the projection 52 are combined to form the internal space of the tube support groove portion 36b. When the insertion groove 36 is formed, the opening 38 is formed by the projection 51, and the pair of through holes 40 are formed by the double-shaped projection 52. Further, the inner faces of the pair of retaining portions 39 are formed in the vicinity of the front end of the double-shaped projections 52, and the outer faces of the pair of retaining portions 39 are formed in the recesses 49 by the regions facing the vicinity of the front ends of the respective projections 52. In a state in which the regulating surface 47 is in contact with the regulating surface 48, a gap is formed between the front end of the projection 51 and the bottom of the intermediate recess 53, and the bridging portion 41 is formed by the gap.

Thus, by providing the retaining portion 39 adjacent to the opening 38 with the through hole 40 opposed in the direction along the axis 19x to the outer tube insertion portion 32, it is not necessary to use another metal mold that moves in the direction of the insertion shaft 32x. The entire outer tube insertion portion 32 including the insertion groove 36 extending in the direction of the insertion shaft 32x can be formed by the metal mold 45 and the metal mold 46. Thereby, the metal mold structure for molding the pulley bracket 30 can be simplified, and the productivity of the window glass shutter 10 including the pulley bracket 30 can be improved.

The drum accommodating portion 60 is formed in a space surrounded by the bottom portion 63 and a cylindrical straight wall 64 formed on the periphery thereof, and the opposite side of the bottom portion 63 is opened as the accommodating portion opening 60a. The cylindrical drum support shaft 65 protrudes from the bottom portion 63, and the take-up drum 23 is rotatably supported in the drum housing portion 60 via the drum support shaft 65. The ninth and tenth views show the axis 65x of the drum support shaft 65 which becomes the center of rotation of the take-up drum 23. The direction along the axis 65x is taken as the up and down direction of the drum frame 20. In the drum frame 20, the wire insertion passage 60b and the wire insertion passage 60c that communicate with the drum housing portion 60 are formed in different directions (the direction in which the pulley carrier 30 and the wire guiding member 18 are completed in the state in which the window glass shutter 10 is completed).

The insertion shaft 61x in the insertion direction of the outer tube insertion portion 61 of the drum-side end portion 21b and the insertion shaft 62x in the insertion direction of the outer tube insertion portion 62 of the drum-side end portion 22b are shown in FIG. The directions along the insertion shafts 61x and 62x are referred to as the axial direction of the outer tube insertion portions 61 and 62, and the directions around the insertion shafts 61x and 62x are referred to as the circumferential direction of the outer tube insertion portions 61 and 62.

The outer tube insertion portion 61 and the outer tube insertion portion 62 have the same configuration as the outer tube insertion portion 32 of the pulley bracket 30 described above. Here, the outer tube insertion portion 62 will be described as a representative, but the outer tube insertion portion 61 is also configured similarly to the outer tube insertion portion 62, and the same portion of the outer tube insertion portion 61 and the outer tube insertion portion 62 are denoted by the same reference numerals in the drawings. .

An insertion groove 66 penetrating in the axial direction is formed inside the outer tube insertion portion 62, and the insertion groove 66 has a narrow groove portion 66a that communicates with the wire insertion passage 60c (the outer tube insertion portion 61 is the wire insertion passage 60b); The outer tube support groove portion 66b is formed by the groove portion 66a, and the introduction groove portion 66c of the funnel-shaped inner surface having an inner diameter gradually increases as it goes away from the outer tube support groove portion 66b. As shown in the ninth figure, an insertion regulating surface 67 is formed in a step portion of the boundary between the narrow groove portion 66a and the outer tube supporting groove portion 66b, and the drum side of the outer tube 22 is inserted into the outer tube supporting groove portion 66b from the introduction groove portion 66c side. The end surface of the end portion 22b abuts against the insertion regulating surface 67, and determines the insertion position of the outer tube 22 to the outer tube insertion portion 62 (the outer tube 22 is excessively moved in the insertion direction).

The outer tube insertion portion 62 is provided with a through insertion groove 66 toward one of the directions along the axis 65x of the drum support shaft 65 (the radial direction of the drum-side end portion 22b of the tube 22 inserted outside the outer tube insertion portion 62). A slit-like opening 68 inside and outside. The opening 68 is formed from the narrow groove portion 66a of the outer tube insertion portion 62 to the outer tube The support groove portion 66b is provided opposite to the tube support groove portion 36b so as to be opposed to the one pair of the stop portions 69 with the opening 68 interposed therebetween. As shown in the eleventh figure, in a state where the drum-side end portion 22b of the outer tube 22 is inserted into the outer tube supporting groove portion 66b, the outer tube 22 is controlled to be withdrawn from the opening 68 by the pair of retaining portions 69 (Fig. 11) Move in the middle to the top). The diameter of the wire 16 is smaller than the width of the opening 68 through which the wire 16 can be inserted or withdrawn through the opening 68.

In the outer tube insertion portion 62, a pair of through holes 70 are formed at positions facing the pair of retaining portions 69 in the direction of the axis 65x of the drum support shaft 65, and a circumferential position is formed between the pair of through holes 70. The insertion control surface 67 and the bridging portion 71 of the introduction groove portion 66c are connected. Each of the through holes 70 penetrates a wall portion formed on the opposite side of the opening 68 in the direction along the axis 65x, and the bridging portion 71 is opposed to the opening 68 in the direction along the axis 65x. The projected area when each of the through holes 70 is viewed along the axis 65x is set to be equal to or larger than the projected area of the retaining portion 69 in the opposing relationship of the axis 69x, and is directed from the through hole 70 side toward the retaining portion 69 side (also In other words, when the outer tube insertion portion 62 is viewed from the side opposite to the tenth view, the positional relationship of the retaining portion 69 corresponding to the outer shape of each of the through holes 70 is accommodated.

A pair of reinforcing ribs 72 are formed on the outer surface of the outer tube insertion portion 62 so as to protrude in the axial direction with the through hole 70 interposed therebetween. Each of the reinforcing ribs 72 is formed in a shape surrounding the outer tube insertion portion 62 in the circumferential direction except for the portion where the opening 68 is formed.

When the glazing shutter 10 is assembled, the wire 16 protruding from the drum-side end portion 22b of the outer tube 22 is inserted into the insertion groove 66 of the outer tube insertion portion 62 through the opening 68, and the drum-side end portion 22b is introduced. The groove portion 66c is inserted into the insertion groove 36 along the insertion shaft 62x. The end surface of the drum-side end portion 22b abuts against the insertion regulating surface 67, and determines the position of the outer tube 22 in the direction of the insertion shaft 62x. The wire 16 is introduced into the drum housing portion 60 from the insertion groove 66 through the wire insertion passage 60c, and is wound around the winding drum 23 In the spiral groove on the circumference. Thus, in a state in which the drum-side end portion 22b of the outer tube 22 is attached to the tube insertion portion 62 outside the drum frame 20 (first to third figures), the wire 16 can be advanced and retracted from the outer tube 22, and the pair of wires 16 The amount of winding of the spiral groove varies depending on the rotation of the winding drum 23. When the outer tube 21 (the drum side end portion 21b) is attached to the outer tube insertion portion 61, the winding of the wire 15 to the winding drum 23 is also performed in the same manner.

A motor unit 25 is mounted in the drum frame 20. As shown in the first to third figures, the motor unit 25 has a motor 25a, a gear case 25b, and a cover portion 25c. The gear box 25b has a reduction gear train that decelerates the rotation of the output shaft of the motor 25a, and a fitting shaft (not shown) that transmits the rotational driving force of the motor 25a via the reduction gear train protrudes from the cover portion 25c. The cover portion 25c covers the opening portion from the housing opening 60a of the drum frame 20 to the opening 68, and the fitting shaft protruding from the cover portion 25c is in the drum housing portion 60 and the winding drum 23 (10th drawing) The fitting force of the motor 25a can be transmitted to the winding drum 23.

The drum frame 20 is a molded product made of a material such as synthetic resin, and is formed by using a metal mold (upper mold) 75 and a metal mold (lower mold) 76 shown in FIG. The metal mold 75 and the metal mold 76 are spaced apart from each other in the direction along the axis 65x of the drum support shaft 65, and are close to positions where the control faces 77, 78 of each other abut. It is also possible to adopt a movable type in which one of the metal mold 75 and the metal mold 76 is formed, and the other form a fixed type which does not move, or both of which form a movable movable type. Since the drum housing portion 60 of the drum frame 20 is a recess opened in the direction of the axis 65x of the drum support shaft 65, it can be relatively moved in the direction along the axis 65x (the downward direction in the eleventh diagram). The metal mold 75 is formed with the metal mold 76. The accommodating portion opening 60a of the drum accommodating portion 60 is formed by a protruding portion (not shown) provided in the mold 75.

Similarly to the drum housing portion 60, the outer tube insertion portion 62 may be made only of the metal mold 75. Formed with a metal mold 76. As shown in the eleventh diagram, the metal mold 75 and the metal mold 76 have concave portions 79, 80 opposed to each other, the metal mold 75 has a projection 81 projecting from the bottom of the concave portion 79, and the metal mold 76 has a double strand protruding from the bottom of the concave portion 80. The shaped projections 82 are recessed between the intermediate recesses 83. The protrusion 81 can be inserted into the intermediate recess 83, and the protrusion 81 is protruded by a smaller amount than the intermediate recess 83. When the drum frame 20 is formed, when the metal mold 75 and the metal mold 76 are brought close to the control surface 77 and the control surface 78, the concave portion 79 and the inner surface of the concave portion 80 form the tube insertion portion 62 including the reinforcing rib 72. Outer shape. Further, the projection 81 is inserted into the intermediate recess 83 by the proximity of the metal mold 75 and the mold 76, and the inner space of the outer tube support groove portion 66b is formed by combining the projection 81 and the projection 82. At this time, the opening 68 is formed by the protrusion 81, and the pair of through holes 70 are formed by the double-shaped protrusion 82. Further, the inner faces of the pair of retaining portions 69 are formed in the vicinity of the front end of the double-shaped projections 82, and the outer faces of the pair of retaining portions 69 are formed by the regions of the recesses 79 opposed to the vicinity of the front ends of the respective projections 82. In a state where the regulating surface 77 is in contact with the regulating surface 78, there is a gap between the front end of the projection 81 and the bottom of the intermediate recess 83, and the bridging portion 71 is formed by the gap. The eleventh figure shows the formation of the outer tube insertion portion 62, but the outer tube insertion portion 61 is still formed by the same metal mold (i.e., the metal mold 75 and the metal mold 76).

Thus, by providing the retaining portions 69 adjacent to the opening 68 in the outer tube insertion portions 61, 62 with the through holes 70 opposed in the direction along the axis 65x, it is not necessary to use another metal moving in the direction of the insertion shafts 61x, 62x. In the mold, the outer tube insertion portions 61, 62 including the insertion grooves 66 extending in the direction of the insertion shafts 61x, 62x are formed by the metal mold 75 and the metal mold 76. Thereby, the metal mold construction for forming the drum frame 20 can be simplified, and the productivity of the window glass shutter 10 including the drum frame 20 can be improved.
