[0021] An embodiment of the present invention will be described below. First, an overview of the parking device 1 will be described. In the following description, the "front side" and the like refer to the front side of the parking device 1, which is the side from which the vehicle 100 enters and exits. The "rear side" and the like refer to the rear side of the parking device 1, which is the opposite side to the "front side." The "side" and "width direction" refer to the left-right direction in FIG. 1. The parking device 1 of this embodiment is a mechanical parking device. The parking device 1 is a puzzle-type multi-story parking device, and has a function of raising and lowering a pallet (mounting platform) 10 and a function of moving it sideways. The parking device 1 of this embodiment has a base frame 2, on which a plurality of parking units 3 are installed.

[0022] The foundation frame 2 is framed by steel materials and constitutes the outer shell of the parking device 1. As shown in Figures 1 to 4, the foundation frame 2 has a five-story structure and is divided into the ground floor A, the second floor B, the third floor C, the fourth floor D, and the fifth floor E. As shown in Figs. 1 and 3, the base frame 2 has a first space a, a second space b, and a third space c in the width direction. On each floor, lateral rails 11a, 11b are installed as shown in Figures 2 and 4. Both of the lateral rails 11a, 11b are steel members installed in the width direction of the foundation frame 2. The lateral rail 11a is installed on the front side of each floor, and the lateral rail 11b is installed on the rear side of each floor.

[0023] The parking unit 3 is composed of a pair of a traverse frame 5 and a pallet 10, as shown in Figs. The traverse frame 5 has a frame body 12, a hoisting device 13, a traverse mechanism 15, a pulley 16, and a fall prevention device 17. Two pulleys 16 are attached to the frame body 12, and four fall prevention devices 17 are attached to the frame body 12. The frame body 12 is a generally rectangular frame made of steel. That is, the frame body 12 is configured with a front horizontal member 41 and a rear horizontal member 42 arranged in parallel with each other and a vertical member 43 connected between them to form a rectangle.

[0024] The winding device 13 is composed of two winding drums 20a, 20b and a drive mechanism 21 that rotates the winding drums 20a, 20b. The winding drums 20a and 20b are for winding wires (cord members) 22a, 22b, 23a, and 23b. The winding drums 20a and 20b are provided with drum side grooves 25 into which the wires 22a, 22b, 23a, and 23b fit. The drive mechanism 21 is made up of a geared motor 26, a connecting member 18 that connects the two winding drums 20a, 20b, and a power transmission mechanism .

[0025] In this embodiment, two winding drums 20a, 20b are connected by a connecting member 18. That is, the winding drums 20a, 20b are attached to both ends of the connecting member 18. A sprocket 27 is provided in the middle of the connecting member 18. A sprocket 30 is attached to the geared motor 26. A chain 31 is wound around the sprocket 30 on the geared motor 26 and a sprocket 27 of the connecting member 18. That is, in this embodiment, the two sprockets 27, 30 and the chain 31 constitute a power transmission mechanism 28.

[0026] The traverse mechanism 15 is made up of four rollers 38 and a drive device (not shown).

[0027] The fall prevention device 17 is a known device, and a stopper member 33 protrudes from and retracts into a box body 32. The box body 32 of the fall prevention device 17 is a vertically long rectangular parallelepiped as shown in Fig. 11. The box body 32 is formed with a slit 37 through which the stopper member 33 protrudes. The box 32 houses a solenoid and a spring (not shown). The stopper member 33 is substantially triangular, and has a substantially horizontal receiving surface 48 and an inclined surface 36 as shown in FIG. The stopper member 33 is constantly protruding from the box body 32 by a spring (not shown). The position of the stopper member 33 is as shown in Fig. 11, in which the substantially horizontal receiving surface 48 faces upward, and the amount of protrusion of the inclined surface 36 increases from the bottom to the top. As described above, a solenoid is built into the box body 32, and the stopper member 33 is recessed into the box body 32 by driving the solenoid.

[0028] Next, the relationship between the members constituting the traverse frame 5 will be described. As described above, the traverse frame 5 has the frame body 12, the hoisting device 13, the traverse mechanism 15, two pulleys 16, and four fall prevention devices 17 provided thereon. The hoisting device 13 is attached to the rear cross member 42 of the frame body 12. The hoisting device 13 is installed on the rear cross member 42. The traverse mechanism 15 is provided on the rear cross member 42 and the front cross member 41 of the frame body 12. That is, two rollers 38 protrude rearward from the rear cross member 42. Also, two rollers 38 protrude forward from the front cross member 41.

[0029] The pulley 16 is disposed on the vertical member 43 of the frame body 12 in the vicinity of the front horizontal member 41 . Two of the four fall prevention devices 17 are vertical members 43 and are provided near the front horizontal member 41. The other two of the four fall prevention devices 17 are vertical members 43 and are provided near the rear horizontal member 42. The four fall prevention devices 17 each have their upper end supported by a vertical member 43 , and most of the box body 32 hangs down from the vertical member 43 . The fall prevention devices 17 are all installed in a position in which the stopper members 33 face the inside of the traverse frame 5. The fall prevention device 17 may be attached to any member or at any position. For example, the fall prevention device 17 may be attached to the front horizontal member 41 or the rear horizontal member 42 of the frame main body 12, the pillars or beams of the foundation frame 2, the lateral rails 11a and 11b, or the like. Furthermore, there are no limitations on the shape or structure of the fall prevention device 17, as long as some kind of obstacle appears under the pallet 10 to prevent the pallet 10 from falling.

[0030] Next, the pallet 10 will be described. The pallet 10 is a platform on which the vehicle 100 is placed. The cross-sectional shape of the main body of the pallet 10 is "concave", and there is a vehicle placement area 45 in which the vehicle 100 is placed in the center in the width direction. The vehicle placement area 45 is a flat area occupied by the vehicle 100. In this embodiment, the wheels of the vehicle 100 come into contact with the ground in the vehicle placement area 45. In this embodiment, the portion of the vehicle placement area 45 where the wheels of the vehicle are placed is the wheel placement area. There are raised portions 46 on both sides of the vehicle placement area (vehicle mounting portion) 45. The upper surface of the raised portions 46 is flat. In the actual pallet 10, there are protrusions and cutouts on the sides and front and rear end faces of the main body for attaching accessories, but the vehicle placement area 45 is a rectangular area that is part or all of the main body of the pallet 10. The front end of the vehicle placement area 45 is the front end of the main body of the pallet 10, and the rear end of the vehicle placement area 45 is the rear end of the main body of the pallet 10. A guide roller 47 is provided on the side surface of the pallet 10 near the rear end. The guide roller 47 rotates freely.

[0031] The parking unit 3 is composed of a traverse frame 5 and a pallet 10, and the pallet 10 is suspended from the traverse frame 5 so as to be able to rise and fall. In this embodiment, the pallet 10 is suspended by four wires 22a, 22b, 23a, and 23b. In this embodiment, the lifting mechanism is made up of members that suspend the four wires 22a, 22b, 23a, and 23b and members that pay out and wind in the four wires 22a, 22b, 23a, and 23b. That is, in this embodiment, the lifting mechanism is made up of the wires 22a, 22b, 23a, and 23b, the winding drums 20a and 20b that wind the wires, the geared motor 26 that drives the winding drums 20a and 20b, the connecting member 18, the power transmission mechanism 28, and the pulley 16 that suspends the wires. The structure for rotating the winding drums 20a and 20b is not limited, and each of the winding drums 20a and 20b may be provided with a separate motor for rotating the winding drums 20a and 20b. In addition, the winding drums 20a and 20b may be directly connected to a geared motor, or the winding drums 20a and 20b may be connected to a geared motor. The motor may be built in. The wires 22a and 22b are front-hanging wires, and one end of each wire is connected to the front side of the pallet 10. The wires 23a and 23b are rear-hanging wires, and one end of each wire is connected to the rear side of the pallet 10.

[0032] In this embodiment, one front hanging wire 22a and one rear hanging wire 23a are wound around one winding drum 20a, and one front hanging wire 22b and one rear hanging wire 23b are wound around the other winding drum 20b. The base ends of the front hanging wires 22a, 22b are wound around the winding drums 20a, 20b, and the tip ends are connected to the front side of the pallet 10 via the pulley 16. That is, the winding path of the front hanging wires 22a, 22b is as shown in Figures 9 and 10(a), and is connected from the winding drums 20a, 20b to the front side of the pallet 10 via the pulley 16. The suspension position of the front hanging wires 22a, 22b between the winding drums 20a, 20b and the pulley 16 is inclined slightly downward from the winding drums 20a, 20b toward the pulley 16. The suspension position of the front hanging wires 22a, 22b between the pulley 16 and the pallet 10 is vertically downward.

[0033] The winding paths of the rear hanging wires 23a, 23b are as shown in Figs. 9 and 10(b), and are connected directly to the rear side of the pallet 10 from the winding drums 20a, 20b. The rear suspension wires 23a, 23b between the winding drums 20a, 20b and the pallet 10 are directed vertically downward.

[0034] Next, the relationship between the base frame 2 and the parking unit 3 will be described. In the parking device 1 of this embodiment, as shown in Fig. 1, two parking units 3 are installed from the second floor B portion to the fourth floor D portion of the base frame 2, and three parking units 3 are installed on the fifth floor E portion of the base frame 2. In this way, on the top floor, the number of spaces and the number of parking units 3 are the same, and on the intermediate floors, the number of parking units 3 is less than the number of spaces. The parking unit 3 is placed on the lateral rails 11a, 11b of the base frame 2. That is, the rollers 38 of the lateral mechanism 15 protruding in the front-rear direction from the frame body 12 of the lateral frame 5 are placed on the lateral rails 11a, 11b installed at the front and rear of the base frame 2. Therefore, by driving the rollers 38 of the traverse mechanism 15, the parking unit 3 moves laterally.

[0035] Next, the basic functions of the parking device 1 will be described. The parking device 1 of this embodiment is a puzzle-type multi-story parking device, and on the top floor, the fifth floor E, parking units 3 are installed in all of the first space a, second space b, and third space c. In contrast, there are no parking units 3 on the ground floor A, which is the loading and unloading floor. On the intermediate floors, the second floor B, third floor C, and fourth floor D, parking units 3 are installed in a number that is one less than the number of spaces.

[0036] When parking the vehicle 100 on the ground floor A, a gate (not shown) is opened and the vehicle 100 is placed into any one of the first space a, the second space b, or the third space c on the ground floor A. When parking the vehicle 100 in a parking unit 3 installed on an upper floor, the pallet 10 of the parking unit 3 is lowered to the ground floor (lowered position) A. For example, when parking the vehicle 100 in the parking unit 3 located in the third space c at the right end of the fourth floor D, the parking units 3 on the lower floors, the third floor C and the second floor B, are moved sideways to open the bottom of the third space c at the right end of the fourth floor D where the vehicle 100 is to be lowered. Alternatively, when the vehicle 100 located in the second space b in the center of the fourth floor D is to be lowered, the parking units 3 are moved sideways to move the parking unit 3 to a position where the space below is vacant.

[0037] Then, the driving mechanism 21 is driven to rotate the winding drums 20a and 20b, and the four wires 22a, 22b, 23a, and 23b are paid out from the winding drums 20a and 20b. As a result, the pallet 10 of the parking unit 3 is lowered to the ground floor A, which is the lowering position. Then, the vehicle 100 is placed on the pallet 10, the drive mechanism 21 is driven to rotate the winding drums 20a, 20b in the reverse direction, and the four wires 22a, 22b, 23a, 23b are wound around the winding drums 20a, 20b, and the four wires 22a, 22b, 23a, 23b are pulled up. As a result, the pallet 10 of the parking unit 3 rises and stops at a predetermined raised position. The raised position of the pallet 10 is near the traverse frame 5 and is slightly lower than the traverse frame 5.

[0038] Next, a characteristic configuration of the parking device 1 of this embodiment will be described. The parking device 1 of this embodiment is characterized by the structure of the winding drums 20a and 20b and the structure of the parts where the wires 22a, 22b, 23a, and 23b are attached to the winding drums 20a and 20b. The parking device 1 of this embodiment is also characterized by the winding paths of the wires 22a, 22b, 23a, and 23b.

[0039] As described above, the parking device 1 of this embodiment lowers the pallet 10 to the ground floor A by rotating the winding drums 20a, 20b and letting out the wires 22a, 22b, 23a, 23b from the winding drums 20a, 20b. Also, the winding drums 20a, 20b are rotated in the reverse direction to wind the four wires 22a, 22b, 23a, 23b around the winding drums 20a, 20b, thereby lifting the pallet 10 to the elevated position. In other words, the pallet 10 is lifted up to the vicinity of the traverse frame 5.

[0040] In this embodiment, as shown in FIG. 12, when the pallet 10 reaches the raised position, the payout positions of the front hanging wires 22a, 22b on the winding drums 20a, 20b are set to be the outermost positions of the winding drums 20a, 20b. That is, when the pallet 10 is on the ground floor A as shown in FIG. 11, the payout positions of the front hanging wires 22a, 22b are the central parts of the winding drums 20a, 20b. In order to raise the pallet 10, the front hanging wires 22a, 22b are wound around the winding drums 20a, 20b, and as the front hanging wires 22a, 22b are retrieved onto the winding drums 20a, 20b, the front hanging wires 22a, 22b get stuck in the grooves 25, and the payout positions of the front hanging wires 22a, 22b gradually move outward. When the pallet 10 reaches the raised position, as shown in FIG. 12, the payout positions of the front hanging wires 22a, 22b on the winding drums 20a, 20b reach the outermost positions of the winding drums 20a, 20b.

[0041] The reason for this setting will be explained below. As described above, the winding path of the front hanging wires 22a, 22b is as shown in Figures 9 and 10(a), and is connected to the front side of the pallet 10 from the winding drums 20a, 20b through the pulley 16. Therefore, the portion between the winding drums 20a, 20b and the pulley 16 forms a horizontal pulling portion 110. On the other hand, in the parking device 1 of this embodiment, a parking unit 3 is installed on each floor, and most of the lifting mechanism is mounted on the lateral frame 5 of the parking unit 3. Therefore, the suspension path of the front hanging wires 22a, 22b is limited to within the parking unit 3, and the height of the lateral pulling portion 110 of the front hanging wires 22a, 22b relative to the pallet 10 cannot be sufficiently secured when the pallet 10 reaches the raised position. In other words, the height of the front hanging wires 22a, 22b in the area (lateral pulling portion 110) from the winding drums 20a, 20b to the pulley 16 relative to the pallet 10 is low. Therefore, if the horizontally-pulled portions 110 of the front-hanging wires 22a, 22b are located above the vehicle placement area 45 of the pallet 10, there is a possibility that the ceiling of the vehicle 100 will interfere with the horizontally-pulled portions 110 of the front-hanging wires 22a, 22b.

[0042] Therefore, in the parking device 1 of this embodiment, as shown in Figures 11 and 12, when the pallet 10 reaches the raised position, the payout positions of the winding drums 20a, 20b of the front hanging wires 22a, 22b are set to be the outermost of the winding drums 20a, 20b. 12, when the pallet 10 reaches the raised position, the horizontally pulled portions 110 of the front hanging wires 22a and 22b move in the width direction and come off from above the vehicle placement area 45 of the pallet 10. Therefore, the ceiling of the vehicle 100 does not come into contact with the horizontally pulled portions 110 of the front hanging wires 22a and 22b.

[0043] As shown in FIG. 13(a), the winding drums 20a and 20b used in this embodiment have a smooth region 55 in the center in the longitudinal direction, and grooves 25 into which the wires 22 and 23 engage are formed in other regions. FIG. 13 is a front view of the left winding drum 20b, and the right winding drum 20a is not shown, but the right winding drum 20a is symmetrical to the left winding drum 20b.

[0044] In this embodiment, the winding drums 20a, 20b are provided with a large number of locking portions 50. In this embodiment, the locking portions 50 are provided at five different positions in the width direction. In this embodiment, the locking portions 50 are two engagement holes 56. Both of the two engagement holes 56 are screw holes. In this embodiment, the area outward from the smooth area 55 at the center of the winding drums 20a, 20b is the winding area 52 for winding the front hanging wires 22a, 22b, and the area inward from the center of the winding drums 20a, 20b is the winding area 53 for winding the rear hanging wires 23a, 23b.

[0045] As described above, in this embodiment, the winding region 52 and the winding region 53 are provided with a plurality of sets of locking portions 50 at five locations. In the following, for ease of understanding, the locking portions 50 will be referred to, from the outside, as locking portion 50 in the first row as locking portion 50a, locking portion 50 in the second row as locking portion 50b, locking portion 50 in the third row as locking portion 50c, locking portion 50d in the fourth row, and locking portion 50e in the fifth row.

[0046] In this embodiment, in the parking unit 3 on the fifth floor, which is the top floor, the ends of the front hanging wires 22a, 22b are fixed to the winding drums 20a, 20b using the central locking portion 50c. The front hanging wires 22a, 22b on the fifth floor start from the central portion of the winding drums 20a, 20b, so that the front hanging wires 22a, 22b can be wound over the entire winding region 52 and many front hanging wires 22a, 22b are held. That is, the front hanging wires 22a, 22b on the fifth floor start from the central portion of the winding drums 20a, 20b, so that the front hanging wires 22a, 22b can be wound over the entire winding region 52 and many front hanging wires 22a, 22b are held. In the parking unit 3 on the fifth floor, the front hanging wires 22a, 22b are wound around the winding drums 20a, 20b, and when the pallet 10 reaches the raised position, the payout positions of the front hanging wires 22a, 22b become the outermost positions of the winding drums 20a, 20b.

[0047] In the parking unit 3 on the second floor, which is a low-rise floor, the ends of the front hanging wires 22a, 22b are fixed to the winding drums 20a, 20b using the outermost first row locking portion 50a. The front hanging wires 22a, 22b on the second floor start near the outside of the winding drums 20a, 20b, so the front hanging wires 22a, 22b are wound in an area closer to the outside of the winding area 52, but the amount that can be held is small. That is, the front hanging wires 22a, 22b on the second floor start near the outside of the winding drums 20a, 20b, so the front hanging wires 22a, 22b are wound from the center to the outermost area, so the amount that can be held is small. Therefore, the required amount of the front hanging wires 22a, 22b is small, which is economical.

[0048] In the parking unit 3 on the second floor, the rear suspension wires 23a, 23b are fixed to the winding drums 20a, 20b using the innermost fifth row locking portion 50e. Therefore, in the parking unit 3 on the second floor, the required amount of the rear suspension wires 23a, 23b is small, which is economical. As for the parking unit 3 on the second floor, the front hanging wires 22a, 22b are wound around the winding drums 20a, 20b, and when the pallet 10 reaches the raised position, the unwinding positions of the front hanging wires 22a, 22b become the outermost positions of the winding drums 20a, 20b.

[0049] In this embodiment, two wires 22, 23 are wound around the winding drums 20a, 20b, but the number of locking portions 50 provided on the winding drums 20a, 20b is five, which is greater than the number of wires 22, 23. The winding drums 20a, 20b employed in this embodiment have a single structure and can be used with the parking units 3 on each floor, and the parts have high interchangeability. Furthermore, by appropriately selecting the locking portion 50 for fixing the wires 22, 23, the amount of the wires 22, 23 used can be minimized.

[0050] Next, the mounting structure of the wires 22 and 23 will be described. In this embodiment, mounting fixtures (fixtures) 60 are used to attach the wires 22, 23 to the winding drums 20a, 20b. The mounting bracket 60 is made of metal and has a curved plate shape as shown in Figures 15 and 16. The overall curvature is approximately equal to the curvature of the outer circumferential surfaces of the winding drums 20a, 20b. Two grooves 61, 62 are provided on the inner surface of the mounting bracket 60. Hereinafter, the grooves 61, 62 provided on the inner surface of the mounting bracket 60 will be referred to as the fixture side grooves 61, 62. Also, the grooves 25 of the winding drums 20a, 20b will be referred to as the drum side groove 25. The shape of the fixture grooves 61, 62 is approximately the same as the drum groove 25 and is approximately half the outer shape of the wires 22, 23.

[0051] The mounting bracket 60 has two through holes 65 arranged side by side in the longitudinal direction. The through holes 65 are provided between the fixing tool grooves 61 and 62.

[0052] In the parking unit 3 on the fifth floor, which is the top floor, the ends of the front hanging wires 22a, 22b are fixed to the winding drums 20a, 20b by using the central locking portion 50c as described above. In the parking unit 3 on the fifth floor, which is the top floor, the rear hanging wires 23a, 23b are also fixed to the winding drums 20a, 20b by using the central locking portion 50c.

[0053] The mounting structure of the wires 22, 23 in the parking unit 3 on the top fifth floor is as shown in Figures 13(b) and 14(a), where the front hanging wires 22a, 22b are sandwiched between the drum gutter 25 and one of the fixing device gutter 61, and the rear hanging wires 23a, 23b are sandwiched between the other drum gutter 25 and the other fixing device gutter 62. Then, a screw 66 is inserted through the two through holes 65 of the mounting bracket 60 and the two locking portions 50c of the third row, and the screw 66 is engaged with the two engagement holes 56 as screw holes. That is, in the parking unit 3 on the fifth floor, which is the top floor, the winding drums 20a and 20b are provided with drum gutters 25 with which the wires 22 and 23 engage, and the mounting bracket 60 has multiple rows of fixture gutters 61 and 62 with which the wires 22 and 23 engage, and one wire 22 is sandwiched between the fixture gutters 61 and the drum gutters 25, and another wire 23 is sandwiched between the other fixture gutters 62 and the other drum gutters 25. In this way, in the parking unit 3 on the fifth floor, one mounting bracket 60 attaches two wires 22 and 23 to the winding drums 20a and 20b.

[0054] In the parking unit 3 on the fifth floor, which is the top floor, the front hanging wires 22a, 22b and the rear hanging wires 23a, 23b are arranged in the two fixed side gutters 61, 62 of the mounting bracket 60, respectively, so that the balance in the height direction is achieved and the inner surface of the mounting bracket 60 faces evenly against the outer surfaces of the winding drums 20a, 20b. Therefore, when the screw 66 is tightened, the two wires 22, 23 are pressed evenly against the winding drums 20a, 20b, and the two wires 22, 23 are firmly fixed to the winding drums 20a, 20b.

[0055] On the other hand, in the parking unit 3 on the intermediate floor, one wire 22, 23 is attached to one mounting bracket 60. Also on the intermediate floor, two wires 22, 23 are attached to each of the winding drums 20a, 20b, so that two mounting brackets 60 are attached to each of the winding drums 20a, 20b.

[0056] For example, the mounting structure of the wires 22, 23 in the parking unit 3 on the second floor is as shown in Figures 13(c) and 14(c), where one of the front suspension wires 22a, 22b is sandwiched between the drum gutter 25 and one of the fixture gutter 61, and a round bar 67 bent into an arc shape is sandwiched between the other fixture gutter 62 and the drum gutter 25. The round bar 67 is a pseudo-rod member inserted to adjust the height. In the parking unit 3 on the second floor, screws 66 are inserted through the two screw holes, i.e., the engagement holes 56, and the screws 66 are engaged with the engagement holes 56. That is, in the parking unit 3 on the second floor, which is the intermediate floor, the winding drums 20a, 20b are provided with drum gutters 25 into which the wires 22, 23 engage, and the mounting bracket 60 has multiple rows of fastener gutters 61, 62 into which the wires 22, 23 engage, with one wire 22 sandwiched between the fastener gutters 61 and the drum gutters 25, and a round bar 67 acting as a quasi-rod member being sandwiched between the other fastener gutters 62 and the other drum gutters 25.

[0057] In the parking unit 3 on the middle floor, either the front hanging wires 22a, 22b or the rear hanging wires 23a, 23b are arranged in one of the two fixture grooves 61, 62 of the mounting bracket 60, and a round bar 67 is arranged in the other fixture groove 61, 62, so that balance in the height direction is achieved and the inner surface of the mounting bracket 60 faces the outer surfaces of the winding drums 20a, 20b evenly. Therefore, when the screw 66 is tightened, the wires 22, 23 are pressed evenly against the winding drums 20a, 20b, and the wires 22, 23 are firmly fixed to the winding drums 20a, 20b.

[0058] In the embodiment described above, the wires 22, 23 are attached to the winding drums 20a, 20b using the plate-shaped mounting brackets 60, but the present invention is not limited to this configuration. 17, for example, a rod-shaped mounting bracket 70 made of metal or the like is directly attached to the tip of the wires 22, 23, and the mounting bracket 70 has a through hole 71. It is preferable that the mounting bracket 70 is curved. Then, the mounting bracket 70 is engaged with the drum side groove 25, and a screw 66 is passed through the through hole 71 of the mounting bracket 70 and the engagement portion 50 to directly fix the wires 22, 23 to the winding drums 20a, 20b. The mounting bracket 60 of this embodiment also functions as an end bracket for preventing the ends of the wires 22, 23 from coming apart.

[0059] 18, the ends of the wires 22, 23 may be folded back, the forward region 72 of the wires 22, 23 may be engaged with one of the fastener grooves 61, the return region 73 may be engaged with the other of the fastener grooves 62, and the wires may be pressed against the winding drums 20a, 20b and fixed with screws 66. According to this configuration, the forward region 72 of the wires 22, 23 is sandwiched between one of the fastener grooves 61 and the drum groove 25, and the return region 73 of the wires 22, 23 is sandwiched between the other of the fastener grooves 62 and the drum groove 25. Therefore, the wires 22, 23 are attached to the winding drums 20a, 20b more firmly.

[0060] In the embodiment described above, two wires 22a, 22b, 23a, and 23b are wound around each of the winding drums 20a and 20b, but the number of wires may be arbitrary, and one wire may be wound around each of the winding drums. In the above embodiment, one front hanging wire 22a and one rear hanging wire 23a are wound around one winding drum 20a, but the front hanging wire 22a may be wound around one winding drum and the rear hanging wire 23a may be wound around another winding drum. In this case as well, a plurality of locking portions 50 for fixing the wire are provided, and the number of locking portions 50 is greater than the number of wires wound around the winding drum.
