Description

[Technical Field]

[0001] The present invention relates to a window regulator and a method for manufacturing the same. [Background technology]

[0002] A known prior art window regulator is shown in Patent Document 1. The configuration of the prior art window regulator will be briefly described as follows.

[0003] The window regulator has a guide rail that extends in the vertical direction and is installed on the door panel of the vehicle. A carrier plate that holds the window glass is mounted on the guide rail so that it can be raised and lowered. The window regulator has a cable (referred to as a wire in Patent Document 1) that pulls the carrier plate. A cable end (referred to as a wire end in Patent Document 1) is fixed to one end of the cable.

[0004] In order to connect a cable end to the carrier plate, the carrier plate is provided with a cylindrical end accommodating section (referred to as an end accommodating section in Patent Document 1) that accommodates the cable end. The back wall of the end accommodating section (referred to as a top wall or bottom wall in Patent Document 1) is a locking section that can lock the cable end. A slit is formed in the outer wall of the end accommodating section along the longitudinal direction of the end accommodating section. A short slit is formed in the back wall of the end accommodating section so as to communicate with the slit, and the short slit extends from the center of the back wall of the end accommodating section toward the outer periphery. With the cable accommodated in the end accommodating section through the slit and the short slit, the cable can be accommodated in the end accommodating section and locked onto the back wall of the end accommodating section by winding the cable from the other end side.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2019-78069 Summary of the Invention [Problem to be solved by the invention]

[0006] However, although slits and short slits are necessary to lock the cable end in the back wall of the end accommodating section, forming slits and short slits in the end accommodating section leads to a decrease in the strength of the carrier plate. In particular, since a large load (weight) from the cable end acts on the back wall, which is the locking section of the end accommodating section, forming short slits in the back wall of the end accommodating section reduces the strength of the carrier plate, making it difficult to increase the durability of the carrier plate.

[0007] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a window regulator and a manufacturing method thereof that can ensure sufficient strength of the carrier plate and increase the durability of the carrier plate. [Means for solving the problem]

[0008] To achieve the above object, one aspect of the present invention provides a window regulator comprising: a guide rail; and a carrier plate that is mounted on the guide rail so as to be able to rise and fall and that holds a window glass. The carrier plate comprises a cable insertion hole having a cable opening that opens on one of an upper surface and a lower surface of the carrier plate and through which a cable that pulls the carrier plate is inserted; and an end accommodating hole that is arranged vertically adjacent to the cable insertion hole and has an end opening that opens on the other of the upper surface and the lower surface of the carrier plate and that accommodates a cable end fixed to an end of the cable. A communication opening that communicates the cable insertion hole with the end accommodating hole is formed in a back wall of the end accommodating hole, and the back wall of the end accommodating hole is a continuous wall that surrounds the communication opening and serves as a locking portion that can lock the cable end.

[0009] A method for manufacturing a window regulator according to one aspect of the present invention involves inserting a cable for pulling a carrier plate from a cable opening opening on one of the upper or lower surfaces of the carrier plate into a cable insertion hole in the carrier plate, and then leading the cable through a communicating opening formed in the rear wall of the end accommodating hole of the carrier plate and out of an end opening opening on the other of the upper or lower surfaces of the carrier plate to the outside of the end accommodating hole, and then pulling the cable out of the cable opening to the outside of the cable insertion hole, thereby accommodating a cable end fixed to the end of the cable from the end opening into the end accommodating hole and engaging it with the rear wall of the end accommodating hole, which is a continuous wall surrounding the communicating opening. [Effects of the Invention]

[0010] According to the window regulator and the manufacturing method thereof according to one aspect of the present invention, the strength of the carrier plate can be sufficiently ensured, thereby increasing the durability of the carrier plate. [Brief explanation of the drawings]

Fig. 9 is a vertical cross-sectional view of a portion of the carrier plate 22.

[0015] As shown in Fig. 1, a window regulator 10 according to this embodiment is a device for raising and lowering a window glass W of a vehicle, and is installed between an inner panel IP and an outer panel EP of a door panel P of the vehicle. In the following embodiment, a window regulator 10 for a vehicle will be described, but the window regulator according to the present invention is not limited to use in a vehicle.

[0016] As shown in Figures 1 to 3, the window regulator 10 includes a guide rail 12 that extends at an incline in the front-to-rear direction relative to the up-down direction, and the guide rail 12 is attached to an inner panel IP via a bracket 14. The guide rail 12 has upright wall portions 16, 18 that rise from both sides in the width direction of the guide rail 12, and an extension portion 20 that extends outward in the width direction from the end of one of the upright wall portions 16. The guide rail 12 is made of a hard material such as stainless steel or an aluminum alloy. Note that the guide rail 12 may extend in the up-down direction instead of extending at an incline in the front-to-rear direction relative to the up-down direction.

[0017] As shown in Figures 1 to 5, a carrier plate 22 that holds the lower end of the window glass W is provided on the guide rail 12 so as to be able to rise and fall. The carrier plate 22 has a clamping portion 24 that clamps one of the standing wall portions 16 so as to be able to slide along the longitudinal direction of the guide rail 12. The carrier plate 22 is made of, for example, resin, aluminum alloy, etc. The window glass W can be raised and lowered by the carrier plate 22 rising and falling along the guide rail 12.

[0018] As shown in FIGS. 1 to 3, the window regulator 10 includes an ascending-side cable 26 as a first cable that pulls the carrier plate 22 in the ascending direction. First cable ends 28 (see FIG. 9) are fixed to both ends of the ascending-side cable 26 by caulking. A first elastic member 30 (see FIG. 9), such as a first spring, that absorbs elongation of the ascending-side cable 26 is provided on one end of the ascending-side cable 26. One end of the ascending-side cable 26 is connected to a predetermined position on the carrier plate 22 via the first cable end 28 and the first elastic member 30. A cable supporter 32 that supports the ascending-side cable 26 is provided on the central side of the guide rail 12 in the longitudinal direction. The cable supporter 30 can be omitted if there is no need to support the ascending-side cable 26.

[0019] The window regulator 10 is equipped with a descending cable 34 as a second cable that pulls the carrier plate 22 in the downward direction. Second cable ends 36 (see FIG. 9) are fixed to both ends of the descending cable 34 by crimping. A second elastic member 38 (see FIG. 9), such as a second spring, that absorbs the elongation of the descending cable 34 is provided on one end side of the descending cable 34. One end of the descending cable 34 is connected to another predetermined portion of the carrier plate 22 via the second cable end 36 and the second elastic member 38.

[0020] As shown in Figures 1 to 3, a direction-changing member 40 that changes the moving direction of the ascending cable 26 is provided at the upper end of the guide rail 12, and is made of, for example, resin, aluminum alloy, or the like. The direction-changing member 40 has a semicircular shape when viewed from the outside and inside of the vehicle. A guide groove 42 is formed on the arc-shaped edge of the direction-changing member 40, through which the ascending cable 26 is slidably wound. A pulley may also be used as the direction-changing member 36.

[0021] 2 and 3, a drive unit 44 for driving the carrier plate 22 to move up and down is provided at the lower end of the guide rail 12. The specific configuration of the drive unit 44 is as follows.

[0022] The drive unit 44 is equipped with a drum 46 that winds and unwinds two cables (the ascending cable 26 and the descending cable 34). The other end of the ascending cable 26 is connected to a predetermined location on the front surface (the surface facing the inside of the vehicle) of the drum 46 via a first cable end 28 (not shown). The other end of the descending cable 34 is connected to a predetermined location on the back surface (the surface facing the outside of the vehicle) of the drum 46 via a second cable end 36 (not shown).

[0023] The drive unit 44 includes a housing 48 provided at the lower end of the guide rail 12. The housing 48 rotatably accommodates the drum 46. In other words, the drum 46 is rotatably provided within the housing 48. The housing 48 is made of, for example, resin, aluminum alloy, or the like.

[0024] The drive unit 44 includes a cover member 50 that is provided to close the open side of the housing 48. The cover member 50 is made of, for example, resin, aluminum alloy, or the like. The drive unit 44 also includes an electric motor 52 that rotates the drum 46 in forward and reverse directions, and the electric motor 52 is provided in the cover member 50. An output shaft (not shown) of the electric motor 52 is operatively connected to a rotating shaft (not shown) of the drum 46 via a reduction mechanism (not shown).

[0025] When the electric motor 52 is driven to rotate the drum 46 in the forward direction, the descending cable 34 is unwound from the drum 46 while the ascending cable 26 is wound onto the drum 46. This causes the carrier plate 22 to rise along the guide rail 12, allowing the window glass W to be raised. On the other hand, when the electric motor 52 is driven to rotate the drum 46 in the reverse direction, the ascending cable 26 is unwound from the drum 46 while the descending cable 34 is wound onto the drum 46. This causes the carrier plate 22 to descend along the guide rail 12, allowing the window glass W to be lowered.

[0026] In addition, instead of the drive unit 44 raising and lowering the carrier plate 22 by driving the electric motor 52, the carrier plate 22 may be raised and lowered by manually operating an operating member (not shown) such as a handle that is interlocked with the rotating shaft of the drum 46.

[0027] As described above, one end of the ascending cable 26 is connected to a predetermined portion of the carrier plate 22 via the first cable end 28 and the first elastic member 30. The other end of the descending cable 34 is connected to another predetermined portion of the carrier plate 22 via the second cable end 36 and the second elastic member 38. The configuration for connecting one end of the ascending cable 26 to a predetermined portion of the carrier plate 22 and the configuration for connecting one end of the descending cable 34 to another predetermined portion of the carrier plate 22 are as follows.

[0028] As shown in Figures 4, 5, 7, 8, and 9, the carrier plate 22 has a first cable insertion hole 54 through which the ascending-side cable 26 is inserted. The first cable insertion hole 54 has a first cable opening 54a that opens into the upper surface of the carrier plate 22. The first cable insertion hole 54 has a first tapered portion 54t that gradually widens toward the first cable opening 54a. The first cable opening 54a of the first cable insertion hole 54 extends in a direction perpendicular to the width direction and longitudinal direction of the guide rail 12.

[0029] 9, the carrier plate 22 has a cylindrical first end accommodating hole 56 that accommodates the first cable end 28 and the first elastic member 30. The first end accommodating hole 56 is arranged next to the first cable insertion hole 54 in the up-down direction (the height direction of the carrier plate 22). The first end accommodating hole 56 has a first end opening 56a that opens to the lower surface of the carrier plate 22.

[0030] 8 and 9, a first communication opening 56c that communicates between the first cable insertion hole 54 and the first end accommodating hole 56 is formed in the center of the back wall 56f of the first end accommodating hole 56. The back wall 56f of the first end accommodating hole 56 is a continuous wall that surrounds the first communication opening 56c and serves as a first locking portion that can lock the first cable end 28 via the first elastic member 30. The first communication opening 56c of the first end accommodating hole 56 extends in a direction perpendicular to the width direction and longitudinal direction of the guide rail 12.

[0031] As shown in Figures 4, 5, 7, 8, and 9, the carrier plate 22 has a second cable insertion hole 58 through which the descending-side cable 34 is inserted. The second cable insertion hole 58 has a second cable opening 58a that opens to the lower surface of the carrier plate 22. The second cable insertion hole 58 has a second tapered portion 58t that gradually widens toward the second cable opening 58a. The second cable opening 58a of the second cable insertion hole 58 extends in a direction perpendicular to the width direction and longitudinal direction of the guide rail 12.

[0032] 9, the carrier plate 22 has a cylindrical second end accommodating hole 60 that accommodates the second cable end 36 and the second elastic member 38. The second end accommodating hole 60 is arranged next to the second cable insertion hole 58 in the up-down direction. The second end accommodating hole 60 has a second end opening 60a that opens to the upper surface of the carrier plate 22.

[0033] 7 and 9, a second communication opening 60c that communicates between the second cable insertion hole 58 and the second end accommodating hole 60 is formed in the center of the back wall 60f of the second end accommodating hole 60. The back wall 60f of the second end accommodating hole 60 is a continuous wall that surrounds the second communication opening 60c and serves as a locking portion that can lock the second cable end 36 via the second elastic member 38. The second communication opening 60c of the second end accommodating hole 60 extends in a direction perpendicular to the width direction and longitudinal direction of the guide rail 12.

[0034] 5, 6, and 9, a first grease supply hole 62 for supplying grease to the first cable end 28 and the first elastic member 30 is formed in the rear surface (surface facing the vehicle outside) of the carrier plate 22 so as to communicate with the first end accommodating hole 56. In addition, a second grease supply hole 64 for supplying grease to the second cable end 36 and the second elastic member 38 is formed in the rear surface of the carrier plate 22 so as to communicate with the second end accommodating hole 60.

[0035] According to the configuration of the window regulator 10 of this embodiment, as described above, the rear wall 56f of the first end accommodating hole 56 is formed with a first communication opening 56c that communicates between the first cable insertion hole 54 and the first end accommodating hole 56. The rear wall 56f of the first end accommodating hole 56 is a continuous wall that surrounds the first communication opening 56c. Therefore, the ascending-side cable 26 can be set on the carrier plate 22 by inserting the ascending-side cable 26 into the first cable insertion hole 54 and leading it out of the first end accommodating hole 56 via the first communication opening 56c. Thereafter, the ascending-side cable 26 is pulled out from the first end opening 56a, whereby the first cable end 28 is engaged with the rear wall 56f of the first end accommodating hole 56. In other words, the first cable end 28 can be engaged with the rear wall 56f of the first end accommodating hole 56 without forming a slit in the carrier plate 22 or a short slit in the rear wall 56f of the first end accommodating hole 56.

[0036] Similarly, a second communication opening 60c that communicates the second cable insertion hole 58 and the second end accommodating hole 60 is formed in the rear wall 60f of the second end accommodating hole 60. The rear wall 60f of the second end accommodating hole 60 is a continuous wall that surrounds the second communication opening 60c. Therefore, the descending-side cable 34 can be set on the carrier plate 22 by inserting the second cable insertion hole 58 and leading it out of the second end accommodating hole 60 via the second communication opening 60c. The descending-side cable 34 is then pulled out from the second end opening 60a, whereby the second cable end 36 is engaged with the rear wall 60f of the second end accommodating hole 60. In other words, the second cable end 36 can be engaged with the rear wall 60f of the second end accommodating hole 60 without forming a slit in the carrier plate 22 or forming a short slit in the rear wall 60f of the second end accommodating hole 60.

[0037] Therefore, according to the window regulator 10 of this embodiment, the strength of the carrier plate 22 can be sufficiently ensured, and the durability of the carrier plate 22 can be increased.

[0038] According to the configuration of the window regulator 10 according to this embodiment, as described above, the first cable insertion hole 54 has the first tapered portion 54t that gradually widens toward the first cable opening 54a. Therefore, during the assembly work of the window regulator 10, it becomes easier to insert the ascending-side cable 26 into the first cable insertion hole 54. Furthermore, even if the ascending and descending trajectory of the carrier plate 22 is curved due to the curved guide rail 12, the lead angle (lead-out angle) of the ascending-side cable 26 can be changed to follow the ascending and descending trajectory of the carrier plate 22, thereby reducing the contact pressure of the ascending-side cable 26 with the edge of the first cable opening 54a.

[0039] Similarly, the second cable insertion hole 58 has a second tapered portion 58t that gradually widens toward the second cable opening 58a. This makes it easier to insert the descent-side cable 34 into the second cable insertion hole 58 during assembly of the window regulator 10. Furthermore, even if the ascending and descending trajectory of the carrier plate 22 is curved, the lead angle of the descending-side cable 34 can be changed to follow the ascending and descending trajectory of the carrier plate 22, thereby reducing the contact pressure of the descending-side cable 34 against the edge of the second cable opening 58a.

[0040] Therefore, according to the window regulator 10 according to this embodiment, the assembly of the window regulator 10 can be improved, and deterioration of the ascending-side cable 26 and the descending-side cable 34 can be suppressed.

[0041] Furthermore, according to the configuration of the window regulator 10 according to this embodiment, as described above, the first cable opening 54a of the first cable insertion hole 54 extends in a direction perpendicular to the width direction and the longitudinal direction of the guide rail 12. Therefore, during the assembly work of the window regulator 10, it is easy to insert the ascending-side cable 26 into the first cable insertion hole 54. Furthermore, even if the ascending and descending trajectory of the carrier plate 22 is curved, the lead angle of the ascending-side cable 26 can be changed to follow the ascending and descending trajectory of the carrier plate 22, thereby reducing the contact pressure of the ascending-side cable 26 with the edge of the first cable opening 54a. Note that the cable opening 54a may be shaped like an elongated hole whose major axis is in a direction perpendicular to the width direction and the longitudinal direction of the guide rail 12, for example.

[0042] Similarly, the second cable opening 58a of the second cable insertion hole 58 extends in a direction perpendicular to the width direction and the longitudinal direction of the guide rail 12. Therefore, during the assembly work of the window regulator 10, it is easy to insert the descending-side cable 34 into the second cable insertion hole 58. Furthermore, even if the ascending and descending trajectory of the carrier plate 22 is curved, the lead angle of the descending-side cable 34 can be changed to follow the ascending and descending trajectory of the carrier plate 22, thereby reducing the contact pressure of the descending-side cable 34 with the edge of the second cable opening 58a. The cable opening 58a can be, for example, an elongated hole shape whose major axis is in a direction perpendicular to the width direction and the longitudinal direction of the guide rail 12.

[0043] Therefore, according to the window regulator 10 according to this embodiment, the assembly of the window regulator 10 can be improved, and deterioration of the ascending-side cable 26 and the descending-side cable 34 can be suppressed.

[0044] Furthermore, according to the configuration of the window regulator 10 of this embodiment, as described above, the first communication opening 56c of the first end accommodating hole 56 extends in a direction perpendicular to the width direction and the longitudinal direction of the guide rail 12. Therefore, even if the ascending and descending trajectory of the carrier plate 22 is curved, the lead angle of the ascending-side cable 26 can be changed to follow the ascending and descending trajectory of the carrier plate 22, thereby reducing the contact pressure of the ascending-side cable 26 with the edge of the first cable opening 54a. The cable opening 56c can be, for example, an elongated hole shape whose major axis is in a direction perpendicular to the width direction and the longitudinal direction of the guide rail 12.

[0045] Similarly, the second communication opening 60c of the second end accommodating hole 60 extends in a direction perpendicular to the width direction and longitudinal direction of the guide rail 12. Therefore, even if the ascending and descending trajectory of the carrier plate 22 is curved, the lead angle of the descending-side cable 34 can be changed to follow the ascending and descending trajectory of the carrier plate 22, thereby reducing the contact pressure of the descending-side cable 34 against the edge of the second cable opening 58a. The cable opening 60c can be, for example, an elongated hole shape whose major axis is in the direction perpendicular to the width direction and longitudinal direction of the guide rail 12.

[0046] Therefore, according to the window regulator 10 of this embodiment, deterioration of the ascending-side cable 26 and the descending-side cable 34 can be suppressed.

[0047] According to the configuration of the window regulator 10 according to this embodiment, a first grease supply hole 62 is formed in the rear surface of the carrier plate 22 and communicates with the first end accommodating hole 56. Therefore, grease can be easily supplied (applied) to the first cable end 28 and the like by simply injecting grease into the first grease supply hole 62. Similarly, a second grease supply hole 64 is formed in the rear surface of the carrier plate 22 and communicates with the second end accommodating hole 60. Therefore, grease can be easily supplied to the second cable end 36 and the like by simply injecting grease into the second grease supply hole 64. The first grease supply hole 62 can be provided at a position where grease injected from the first grease supply hole 62 can be applied to the inner wall of the first end accommodating hole 56 when the first cable end 28 slides within the first end accommodating hole 56. For example, the first grease supply hole 62 can be provided in a location where the first cable end 28 is located when no load is applied to the first elastic member 30. Similarly, the second grease supply hole 64 can be provided at a position where grease injected from the second grease supply hole 64 can be applied to the inner wall of the second end accommodating hole 60 when the second cable end 36 slides inside the second end accommodating hole 60. For example, the second grease supply hole 64 can be provided at a location where the second cable end 36 is located when no load is acting on the second elastic member 38.

[0048] Therefore, according to the window regulator 10 of this embodiment, deterioration due to wear of the first cable end 28 and the like can be suppressed.

[0049] Furthermore, according to the configuration of the window regulator 10 according to this embodiment, the first end opening 56a of the first end accommodating hole 56 opens to the lower surface of the carrier plate 22. The second cable opening 58a of the second cable insertion hole 58 opens to the lower surface of the carrier plate 22. Therefore, even if water seeps into the first cable insertion hole 54 or the second end accommodating hole 60, the water can be discharged from the first end opening 56a of the first end accommodating hole 56 or the second cable opening 58a of the second cable insertion hole 58.

[0050] Therefore, according to the window regulator 10 of this embodiment, the drainage performance of the carrier plate 22 can be improved.

[0051] Next, a method for manufacturing the window regulator according to this embodiment will be described with reference to Figures 10 to 13. Figures 10 to 13 are diagrams for explaining the method for manufacturing the window regulator according to this embodiment.

[0052] 10 to 13, the method for manufacturing a window regulator according to this embodiment is a method for manufacturing window regulator 10, and includes steps 1, 2, 3, and 4. The specific content of each step in the method for manufacturing a window regulator according to this embodiment is as follows:

[0053] 1st process 10 , one end of the ascending-side cable 26 is inserted from the first cable opening 54a into the first cable insertion hole 54, and then led out of the first end accommodating hole 56 from the first end opening 56a via the first communication opening 56c, thereby setting the ascending-side cable 26 on the carrier plate 22. Then, the first cable end 28 is fixed to one end of the ascending-side cable 26 by caulking, and the first elastic member 30 is attached to the one end side of the ascending-side cable 26.

[0054] 2nd process After the first step is completed, as shown in Fig. 11 , the ascending-side cable 26 extending out from the first cable insertion hole 54 is pulled out from the first cable opening 54a to the outside of the first cable insertion hole 54. This allows the first cable end 28 and the first elastic member 30 to be accommodated in the first end accommodating hole 56 from the first end opening 56a and engaged with the inner wall 56f of the first end accommodating hole 56, which is a continuous wall surrounding the first communication opening 56c. In other words, the first cable end 28 can be accommodated in the first end accommodating hole 56 and engaged with the inner wall 56f of the first end accommodating hole 56 via the first elastic member 30.

[0055] 3rd process 12, one end of the descending cable 34 is inserted through the second cable opening 58a into the second cable insertion hole 58, and then led out of the second end accommodating hole 60 from the second end opening 60a via the second communication opening 60c, thereby setting the descending cable 34 on the carrier plate 22. Then, the second cable end 36 is fixed to one end of the descending cable 34 by crimping, and the second elastic member 38 is attached to one end of the descending cable 34.

[0056] 4th step After the third step is completed, as shown in Fig. 13, the downward-side cable 34 protruding from the second cable insertion hole 58 is pulled out from the second cable opening 58a to the outside of the second cable insertion hole 58. This allows the second cable end 36 and the second elastic member 38 to be accommodated in the second end accommodating hole 60 from the second end opening 60a and engaged with the inner wall 60f of the second end accommodating hole 60, which is a continuous wall surrounding the second communication opening 60c. In other words, the second cable end 36 can be accommodated in the second end accommodating hole 60 and engaged with the inner wall 60f of the second end accommodating hole 60 via the second elastic member 38.

[0057] According to the manufacturing method of the window regulator of this embodiment, the ascending-side cable 26 is set on the carrier plate 22 by inserting the ascending-side cable 26 into the first cable insertion hole 54 and leading it out of the first end accommodating hole 56 via the first communication opening 56c. Then, the ascending-side cable 26 is pulled out of the first cable insertion hole 54 from the first cable opening 54a, thereby locking the first cable end 28 in the rear wall 56f of the first end accommodating hole 56. In other words, the first cable end 28 can be locked in the rear wall 56f of the first end accommodating hole 56 without forming a slit in the carrier plate 22 or forming a short slit in the rear wall 56f of the first end accommodating hole 56.

[0058] Similarly, the descending-side cable 34 is inserted into the second cable insertion hole 58 and led out of the second end accommodating hole 60 via the second communication opening 60c, thereby setting the descending-side cable 34 on the carrier plate 22. Thereafter, the descending-side cable 34 is pulled out of the second cable insertion hole 58 from the second cable opening 58a, thereby engaging the second cable end 36 with the rear wall 60f of the second end accommodating hole 60. In other words, the second cable end 36 can be engaged with the rear wall 60f of the second end accommodating hole 60 without forming a slit in the carrier plate 22 or forming a short slit in the rear wall 60f of the second end accommodating hole 60.

[0059] Therefore, according to the manufacturing method of the window regulator according to this embodiment, the strength of the carrier plate 22 can be sufficiently ensured, and the durability of the carrier plate 22 can be improved.

[0060] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention. [Industrial Applicability]
