Fig. 3 (a) is a perspective view of the fixing member 20 from above obliquely to the left near front, fig. 3 (B) is a side view of the fixing member 20 from the left side, and fig. 3 (C) is a front view of the fixing member 20 from the near front. The fixing member 20 has a rectangular parallelepiped shape in which a portion extending from the rear side toward the front side in a state of being attached to the door main body 101 is in a longitudinal direction. The fixing member 20 has a setting portion 21 fixed to the door main body 101. The installation portion 21 is a rear surface of the rear side and is formed substantially flat. The fixing member 20 can fix the installation portion 21 to the surface of the door main body 101 by attaching, for example, a double-sided tape to the installation portion 21. The lever handle operating instrument 10 can fix the installation portion 21 to the door main body 101 by using a double-sided tape, and thus can be mounted to the door 100 without modifying the door 100.
The fixing member 20 has a hollow box shape having a front opening 26, and left and right side plate portions 27 each have an opening 22. The opening 22 is formed in a size and shape that allows insertion of the free end side of the grip portion of the lever handle 104. When the lever handle operation tool 10 is installed, the grip portion of the lever handle 104 is inserted from the opening 22 on the right side, and the openings 22 on both sides are inserted so as to protrude from the opening 22 on the left side to the outside of the fixing member 20. The fixing member 20 has an inner space 24 defined by an upper plate portion 28, a bottom plate portion 29, and left and right side plate portions 27. In order to insert the lever handle 104 into the fixing member 20, the opening 22 may be provided only on the side close to the rotation axis of the lever handle 104, or the opening 22 may not be provided on the side distant from the rotation axis of the lever handle 104.
In the lever handle operation tool 10, the movable member 30 is fitted into the fixed member 20 so as to be movable in the internal space 24 of the movable member 30 shown in fig. 2. The upper plate portion 28, the bottom plate portion 29, and the left and right side plate portions 27 function as guide portions 23 that guide the movable member 30 when the movable member is moved toward the front side and the rear side.
Fig. 4 (a) to 4 (C) are external views showing the removal of the movable member 30 from the lever handle operating instrument 10. Fig. 4 (a) is a perspective view of the movable member 30 viewed obliquely from above and toward the left, fig. 4 (B) is a perspective view of the movable member 30 viewed from the bottom surface side, and fig. 4 (C) is a side view of the movable member 30 viewed from the left side. The movable member 30 has a front-side operation portion 36 and a moving portion 33 extending inward from the operation portion 36. As shown in fig. 2 (a) to 2 (D), the movable member 30 is inserted into the opening of the front surface of the fixed member 20 from the rear side of the moving portion 33. The moving portion 33 has a size and shape along the guide portion 23 of the fixing member 20, and moves along the guide portion 23. More specifically, the moving portion 33 is formed in a frame shape having an insertion space 34 through which the lever handle 104 can be inserted, by using an upper moving portion 33A that moves above the grip portion, a lower moving portion 33B that moves below the grip portion, a front plate portion 33C that connects the upper moving portion 33A and the lower moving portion 33B on the front side, and a rear plate portion 33D that connects the upper moving portion 33A and the lower moving portion 33B on the rear side. In addition, in the moving portion, an abutment portion 31 is formed from the upper moving portion 33A to the front plate portion 33C.
The lever handle operating tool 10 is provided to the door main body 101 such that the grip portion of the lever handle 104 is inserted from the right opening 22 of the fixing member 20, inserted into the insertion space 34 of the moving portion 33, and protrudes outward from the left opening 22 of the fixing member 20. The opening 22 and the insertion space 34 are formed so as to be aligned with each other so that the grip portion of the lever handle 104 can be inserted from right to left. Further, an abutting portion 31 is formed inside the moving portion 33, and the abutting portion 31 can abut against a grip portion of the lever handle 104 in a state where the lever handle operating tool 10 is installed, that is, in a state where the grip portion is inserted into the insertion space 34.
As shown in fig. 4 (B), the contact portion 31 of the movable member 30 has a pressing surface 32, and the pressing surface 32 presses down the grip portion of the lever handle 104 while sliding with respect to the grip portion when the internal space 24 shown in fig. 3 moves toward the installation portion 21. Since the pressing surface 32 is inclined downward from the rear side toward the near front side, when the abutting portion 31 moves toward the installation portion 21, the gripping portion of the lever handle 104 can be pressed while sliding with respect thereto.
As shown in fig. 4 (B) and 4 (C), the inclination angle of the pressing surface 32 is different between the right end and the left end. Specifically, in the pressing surface 32, the lower end of the side away from the rotation axis of the lever handle 104 reaches a position lower than the lower end of the side closer to the rotation axis of the lever handle 104, and the inclination angle of the pressing surface 32 is formed larger on the side away from the rotation axis of the lever handle 104. The pressing surface 32 of the lever handle operating instrument 10R attached to the rear surface of the door 100 is shown in fig. 4 (B) and 4 (C). Since the lever handle operating instrument 10 attached to the front surface of the door 100 is left side (see fig. 1 a and 1C) on the side away from the rotation axis of the lever handle 104, the lower end of the left end portion of the pressing surface 32 is formed to reach a position lower than the lower end of the right end portion, and the inclination angle of the left end portion is larger than the inclination angle of the right end portion.
As shown in fig. 3 (a) and 3 (C), the fixed member 20 has a stopper 25 for preventing the movable member 30 from being separated from the guide 23. The stopper portion 25 protrudes toward the inner space 24 from a bottom plate portion 29 forming the inner side of the guide portion 23. After the movable member 30 is inserted into the internal space 24 of the fixed member 20, the stopper 25 is driven from an opening (not shown) formed in the bottom surface of the fixed member 20. On the other hand, as shown in fig. 4 (B), the lower moving portion 33B of the movable member 30 has a groove 35 that prevents interference with the stopper portion 25 when the moving portion 33 moves along the guide portion 23. The groove 35 is formed on the bottom surface of the movable member 30 so as to extend from the front side to the rear side with a width larger than that of the stopper 25, and by fitting the stopper 25 into the groove 35, interference between the stopper 25 and the moving portion 33 is not generated.
Next, the operation of the lever handle operation tool 10 will be described with reference to fig. 5. Fig. 5 (a) to 5 (D) are cross-sectional views of the lever handle manipulation instrument 10. Fig. 5 (a) and 5 (B) are cross-sectional views of the lever handle operation tool 10 corresponding to fig. 2 (a) and 2 (B), and fig. 5 (C) and 5 (D) are cross-sectional views of the lever handle operation tool 10 corresponding to fig. 2 (C) and 2 (D). As shown in fig. 5 (a) and 5 (C), in a state in which the lever handle operation tool 10 is not provided in the door 100, the movable member 30 can be fitted into the fixed member 20 until the deepest portion of the moving portion 33 comes into contact with the deepest surface in the inner space 24. As shown in fig. 5 (B) and 5 (D), the movable member 30 can be pulled out from the fixed member 20 until the deepest portion of the groove 35 comes into contact with the stopper 25. In this way, the movable member 30 can move toward the front side and the rear side without being separated from the fixed member 20.
When the lever handle operation tool 10 of the present embodiment is provided to the door 100, the movable member 30 is pushed in the direction of the installation portion 21, so that the contact portion 31 moves toward the installation portion 21, and the pressing surface 32 of the contact portion 31 can be pushed down while sliding with respect to the grip portion of the lever handle 104. By this operation, the lever handle 104 is turned downward, and the latch mechanism is operated, so that the latch pin of the door main body 101 is disengaged from the latch receiver, and the door 100 can be opened. According to the lever handle operation tool 10 of the present embodiment, the door 100 can be opened by a tool small enough to the door main body 101 without performing an operation of holding the lever handle 104 and pressing down.
In the present embodiment, the push-down surface 32 is formed such that the inclination angle of the left end portion distant from the rotation axis of the lever handle 104 is larger than the inclination angle of the right end portion. According to this structure, the lever handle manipulation instrument 10 can press the left side of the grip portion of the lever handle 104 more greatly by the pressing surface 32. By pressing the left side of the grip portion of the lever handle 104 more, the rotation angle of the lever handle 104 can be increased, and the latch can be disengaged from the latch receiver more reliably.
Next, a door opener 40 according to the present embodiment will be described with reference to fig. 6. Fig. 6 is an external perspective view of the door opener 40. Fig. 6 (a) is a perspective view of the door opener 40 from the back side, and fig. 6 (B) is a perspective view of the door opener 40 from the near front side.
As shown in fig. 1, the door opener 40 is used in combination with the lever handle operating implement 10 described above. The door opener 40 includes a base 41, a mounting portion 42 fixed to a door body 101 of the door 100, and a pressing portion 43 that presses the door frame 102 by a biasing member. The base 41 has a rectangular shape long in the up-down direction. The mounting portion 42 and the pressing portion 43 are integrated with respect to the base portion 41. The mounting portion 42 has an insertion portion 42A extending inward from the center of the base 41 in the vertical direction to form an opposing portion 420A opposing the base 41. The insertion portion 42A is integrally formed with the base 41. The end of the door main body 101 is inserted into the inside of the insertion portion 42A. The door opener 40 is inserted into the end of the door main body 101 inside the insertion portion 42A to determine the position of attachment to the door main body 101. The mounting portion 42 includes a screw 42B penetrating the base 41. The tip of the screw 42B protrudes inward of the insertion portion 42A, and the movable portion 42C is fixed to the tip. The movable portion 42C moves toward the base 41 when the screw 42B is loosened, and moves toward the opposing portion 420A when the screw 42B is tightened. The mounting portion 42 is inserted into the door main body 101 inside the insertion portion 42A, and moves the movable portion 42C in the direction of the opposing portion 420A, so that the door opener 40 can be mounted to the door main body 101 by sandwiching the door main body 101 between the movable portion 42C and the opposing portion 420A. Accordingly, the door opener 40 can be mounted to the door main body 101 without modifying the door 100.
The pressing portion 43 includes a compression coil spring 43A (an example of a "biasing member" described in the present application) and a pressing plate 43B. One end of the compression coil spring 43A is fixed to the base 41, and the other end of the compression coil spring 43A is fixed to the pressing plate 43B. When the door opener 40 is attached to the door main body 101, the compression coil spring 43A is compressed in comparison with the natural length, and the frame 102 is continuously pressed via the pressing plate 43B. In this state, when the movable member 30 of the lever handle operating tool 10 is operated to move toward the installation portion 21, the lever handle 104 is rotated downward, the latch mechanism is operated, the latch pin of the door main body 101 is disengaged from the latch receiver, and the door main body 101 is rotated toward the front side by the force of the pressing plate 43B pressing the frame 102. According to the lever handle operation tool 10 of the present embodiment, when the pressing surface 32 of the abutment portion 31 presses the grip portion of the lever handle 104, the latch is disengaged from the latch receiver, and the pressing portion 43 presses the frame 102, whereby the door 100 is opened. Thus, according to the lever handle operating instrument 10 of the present embodiment, the door 100 can be opened without modifying the door and without holding the lever handle 104 to perform a pressing operation. Further, according to the lever handle operation tool 10, the door 100 can be opened only by one operation of pressing the movable member 30 toward the setting portion 21.
The lever handle operation tool 10R shown in fig. 1 provided on the rear side of the door main body 101 has the same structure and configuration as the lever handle operation tool 10 provided on the front side except that the contact portion 31 is opposite to the contact portion 31 of the lever handle operation tool 10 provided on the front side of the door main body 101. Further, the abutting portion 31 can use the lever handle operation tool 10 for the lever handle 104 directed to either one of the left and right sides by making the left and right shapes, that is, the left and right inclination angles the same.
Modification 1
Next, modification 1 of the present embodiment will be described with reference to fig. 7. In the lever handle operation tool 10 of the above embodiment, the moving portion 33 of the movable member 30 is configured to move along the inner peripheral surface of the guide portion 23 of the fixed member 20, but the moving portion 33 may be configured to move along the outer peripheral surface of the guide portion 23.
Fig. 7 (a) and 7 (B) are cross-sectional views of the lever handle operation tool 10 according to the present modification from the left side. Fig. 7 (a) shows a state in which the movable member 30 is pushed into the deepest part of the fixed member 20, and fig. 7 (B) shows a state in which the movable member 30 moves to the near side of the fixed member 20. In the present modification, the guide portion 23 is inserted inside the moving portion 33, and the moving portion 33 moves along the outer peripheral surface of the guide portion 23. As in the present modification, for example, the movable member 30 may be fitted into the fixed member 20 so that the moving portion 33 moves along the outside of the guide portion 23. In the present modification, the stopper 25 and the groove 35 are not provided, but the stopper 25 may be provided inside the lower moving portion 33B and the groove 35 may be provided outside the bottom plate portion 29.
Modification 2
Next, modification 2 of the present embodiment will be described. In the door opening device 50 of the above embodiment, the door opener 40 is attached to the door main body 101, but the door opener 40 may be configured to be attached to the frame 102 on the back side of the door 100 and the wall in the vicinity thereof via a fixing portion, and the pressing portion may press the back side of the door main body 101.
(second embodiment)
In fig. 8 to 15, the lever handle operating instrument 12 according to the present embodiment includes a fixed member 60 and a movable member 70.
The fixing member 60 has a setting portion 61 fixed near the lever handle 104 of the door 100. The installation portion 61 is a rear surface of the rear side and is formed substantially flat. The fixing member 60 can fix the installation portion 61 to the surface of the door main body 101 by attaching, for example, a double-sided tape to the installation portion 61.
The fixed member 60 is a box-shaped member having an inner space 64, which is divided by an upper plate portion 68, a bottom plate portion 69, and left and right side plate portions 67, and which has an abutment portion 71 of a movable member 70, which will be described later, and which is movable toward the installation portion 61. The movable member 70 is inserted into the interior space 64 through the front opening 66 on the proximal front side. Guide portions 63, for example, in the form of grooves, in which the movable member 70 is movable toward the installation portion 61 are provided on, for example, the upper left and right inner surfaces of the fixed member 60.
The front end edge of the bottom plate portion 69 and a part of the front end edges of the left and right side plate portions 67 form a notch step portion 65 that is lowered inward from the front end edge of the guide portion 63. The notched step portion 65 corresponds to the opening portion 22 in the first embodiment, and is a portion on the free end side of the grip portion of the lever handle 104 interposed between the notched step portion and the abutment portion 71 of the movable member 70 described later. The notch step 65 is located below the guide 63, and the notch step 65 is shorter than the guide 63 with respect to the depth dimension of the side plate 67. As shown in fig. 12 and 13, a circular groove 54 is provided on the inner surface side of the installation portion 61, for example, in which one end of the compression coil spring 53 is disposed.
The movable member 70 has an abutment portion 71 that can abut against the grip portion of the lever handle 104, and is movable relative to the fixed member. The abutment portion 71 has a pressing surface 72 that presses the grip portion while sliding with respect to the grip portion when the movable member 70 is moved in the direction of the installation portion 61.
The movable member 70 includes a front-side operation portion 76 and a moving portion 73 extending inward from the operation portion 76. The operation unit 76 is configured to be able to receive, for example, an input of a force in the moving direction of the movable member 70 to the setting unit 61 and an input of a force from an obliquely upper direction intersecting the moving direction. The operation portion 76 has a convex curved surface on the side opposite to the installation portion 61 side in the moving direction of the movable member 70, for example. The operation portion 76 extends upward from the upper portion of the front surface side of the fixing member 60, that is, the upper plate portion 68. The operation portion 76 may extend to the left and right than the moving portion 73, or may extend downward than the moving portion 73. In the illustrated example, the operation portion 76 extends upward, downward, leftward, and rightward with respect to the moving portion 73, wherein the upward extension is the largest. This is to facilitate the operation of pulling the hand from above by placing the hand on the operation portion 76.
The movable member 70 is inserted into the front opening 66 of the fixed member 60 from the rear plate portion 73D side of the moving portion 73 described later. The moving portion 73 has a size and shape along the guide portion 63 of the fixing member 60, and moves along the guide portion 63. More specifically, the movable member 70 includes an abutment portion 71, an upper moving portion 73A, a back plate portion 73D, and a stopper portion 75. The upper moving portion 73A is a portion that moves above the grip portion of the lever handle 104 while being guided by the guide portion 63. The upper moving portion 73A is configured to extend to the left and right of the portion other than the upper moving portion 73A in the moving portion 73 so as to engage with the groove-shaped guide portion 63 in the up-down direction. The back plate 73D is located at the rear end of the upper moving part 73A, and extends downward from the rear end. The movable member 70 of the present embodiment is formed such that the lower end of the back plate 73D does not contact the upper surface of the bottom plate 69 of the fixed member 60, but may be formed such that the lower end of the back plate 73D slides on the upper surface of the bottom plate 69 of the fixed member 60.
An insertion space 74 through which the grip portion of the lever handle 104 is inserted is formed between the abutment portion 71 and the stopper portion 75 of the movable member 70. Unlike the first embodiment, the second embodiment does not provide a lower moving portion in the movable member 70, and the insertion space 74 is also opened downward.
The stopper 75 is a portion that abuts against the grip portion of the lever handle 104 in a state where the movable member 70 is guided by the guide 63 when the movable member 70 is moved in a direction opposite to the installation portion 61 side. The stopper 75 is provided at a lower portion of the back plate 73D. The inner plate portion 73D including the stopper portion 75 is formed in a size that can move toward the installation portion 61 side and the opposite side (front opening 66 side) within the internal space 64 of the fixing member 60 with the movement of the moving portion 73.
The abutment portion 71 is provided on the front side of the stopper portion 75 below the upper moving portion 73A. The contact portion 71 and the pressing surface 72 correspond to the contact portion 31 and the pressing surface 32 in the first embodiment, respectively. Since the pressing surface 72 is inclined downward from the rear side toward the front side, when the contact portion 71 moves toward the installation portion 61, the grip portion of the lever handle 104 can be pressed while sliding with respect thereto. In the present embodiment, the abutting portion 71 and the pressing surface 72 are formed symmetrically in the left-right direction, and the lever handle manipulating tool 12 can be used for the lever handle 104 directed to either one of the left and right directions.
As shown in fig. 11, the moving portion 73 and the operating portion 76 of the movable member 70 are integrated by fastening with, for example, a screw 80. As an example, mounting portions 82 and 83 inserted into the inner side of the moving portion 73 are provided in the upper and lower sides of the inner side of the operating portion 76, the upper moving portion 73A is fastened to the mounting portion 82, and the abutting portion 71 is fastened to the mounting portion 83.
As shown in fig. 14 and 15, the compression coil spring 53 is disposed between the fixed member 60 and the stopper portion 75 of the movable member 70, and the movable member 70 is biased in a direction (near-front side) opposite to the installation portion 61 of the fixed member 60. In a state where the movable member 70 is guided by the guide portion 63, the stopper portion 75 abuts against the grip portion of the lever handle 104, and therefore the movable member 70 does not come off from the fixed member 60 even if the movable member 70 is biased by the compression coil spring 53.
(action)
In fig. 14 and 15, in the lever handle operating tool 12, when the movable member 70 is moved toward the setting portion 61 in order to press the grip portion of the lever handle 104, a force is input to the operating portion 76. The operation portion 76 is formed as a curved surface protruding toward the side opposite to the installation portion 61 side in the moving direction of the movable member 70, and is capable of receiving an input of force in the moving direction of the movable member 70 on the installation portion 61 side and an input of force obliquely upward from the crossing of the moving direction. Therefore, the position of the operation portion 76 is located at a low position in terms of the user, and even if the operation portion 76 is pushed obliquely upward, the movable member 70 can be smoothly moved toward the installation portion 61. When the movable member 70 is moved toward the inner space 64 of the fixed member 60, the contact portion 71 of the movable member 70 moves toward the installation portion 61, and the holding portion of the lever handle 104 is pushed down while the pushing down surface 72 of the contact portion 71 slides with respect to the holding portion. Thus, the latch mechanism operates, and the latch pin of the door main body 101 is disengaged from the latch receiver, so that the door 100 can be opened.
Further, since the operation portion 76 extends upward from the front side upper portion of the fixing member 60, that is, above the upper plate portion 68 of the fixing member 60, the operation of pulling the door 100 toward the front side to open the door can be easily performed by putting a hand on the operation portion 76. Further, since the insertion space 74 of the movable member 70 is also opened downward, the pressing of the grip portion of the lever handle 104 by the abutment portion 71 is not hindered halfway compared to the case where the lower side of the insertion space 74 is closed, and the lever handle 104 can be appropriately rotated to the position where the latch is disengaged from the latch receiver.
(third embodiment)
In fig. 16 to 20, in the lever handle operation tool 13 according to the present embodiment, the fixing member 60 includes: a first fixing member 91 having a setting portion 61; the second fixing member 92 having the guide portion 63 is attached to the first fixing member 91.
The first fixing member 91 includes a mounting portion 61, an upper plate portion 88, and left and right side plate portions 87. The lower side (bottom surface opening 81) and the near front side (front surface opening 86) of the first fixing member 91 are opened.
The second fixing member 92 has a back plate portion 84, an upper plate portion 68, left and right side plate portions 67, and a bottom plate portion 69, and the movable member 70 is inserted through the front opening 66. The guide 63 is provided to the second fixing member 92. The inner plate 73D of the movable member 70 is movable toward the back plate 84 and the opposite side (front opening 66) thereof in the inner space 64 of the second fixed member 92 in response to the movement of the movable member 73. Further, for example, the inner end portions of the side plate portions 67 on both sides of the second fixing member 92 are provided with the protruding strips 90 extending in the up-down direction. Since other portions of the second fixing member 92 are the same as those of the fixing member 60 of the second embodiment, the same reference numerals are given to the same portions in the drawings, and the description thereof is omitted.
In the first fixing member 91, the lower portions of the front end edges of the left and right side plate portions 87 become notched step portions 85 that descend farther to the rear than the upper portions. The notched step portion 85 is a portion on the free end side of the grip portion of the lever handle 104 interposed between the abutment portion 71 of the movable member 70. Regarding the depth dimension of the side plate portion 87, the portion of the cutout step portion 85 is shorter than the upper portion.
The position of the second fixing member 92 relative to the first fixing member 91 is adjusted according to the position of the grip portion of the lever handle 104 relative to the door main body 101 (door 100). In the illustrated example, three mounting grooves 87A, 87B, 87C are formed in the first fixing member 91. The mounting grooves 87A, 87B, 87C extend in the vertical direction, open downward, and are formed at predetermined intervals in parallel with the depth direction of the first fixing member 91. The arrangement pitch of the mounting grooves 87A, 87B, 87C may or may not be constant.
By inserting the protruding strip 90 of the second fixing member 92 into any one of the mounting grooves 87A, 87B, 87C, the mounting position of the second fixing member 92 with respect to the first fixing member 91 in the depth direction can be adjusted. The second fixing member 92 is slidably attached to the first fixing member 91 in a direction intersecting the moving direction of the movable member 70, for example, in the up-down direction.
In order to prevent the second fixing member 92 from falling off the first fixing member 91, engagement portions (not shown) may be provided in which the mounting grooves 87A, 87B, 87C engage with the protruding pieces 90. The second fixing member 92 may not be detached from the first fixing member 91 by adhesion, fastening, or the like.
(action)
In the lever handle operating tool 13, by adjusting the position of the second fixing member 92 relative to the first fixing member 91, the lever handle operating tool can be applied to various types of doors having different positions of the grip portion of the lever handle 104 relative to the door main body 101 (door 100). Fig. 17 and 18 show a case where the grip portion is relatively far from the door main body 101, and the protruding strip 90 is inserted into the mounting groove 87C. Fig. 19 and 20 show a case where the grip portion is relatively close to the door main body 101, and therefore the protruding strip 90 is inserted into the mounting groove 87A. In this case, the notched step portion 85 of the first fixing member 91 is substantially aligned with the notched step portion 85 of the second fixing member 92 (see fig. 19 and 20).
The movable member 70 is guided by the guide portion 63 of the second fixing member 92 to move toward the installation portion 61 of the first fixing member 91, and at this time, the holding portion 104 of the lever handle 104 is pushed down while sliding against the pushing surface 72 of the abutment portion 71 of the movable member 70. Thus, the latch mechanism operates, and the latch pin of the door main body 101 is disengaged from the latch receiver, so that the door 100 can be opened.
Other portions are the same as those of the second embodiment, and therefore the same reference numerals are given to the same portions in the drawings, and the description thereof is omitted.
(modification)
In fig. 21, in the lever handle operation tool 13 according to the present modification, instead of the mounting grooves 87A, 87B, 87C in the first fixing member 91 of the third embodiment, a bottom plate portion 89 is provided in the first fixing member 91, and three through holes 89A, 89B, 89C are provided in the bottom plate portion 89, for example. Further, in place of the protruding strip 90 of the second fixing member 92, a recess 96 having the same size as the through holes 89A, 89B, 89C is provided in the bottom plate portion 69 of the second fixing member 92. Further, by driving the stopper member 94 into the recess 96 from any one of the through holes 89A, 89B, 89C, the position of the second fixing member 92 with respect to the first fixing member 91 can be set. The arrangement pitch of the through holes 89A, 89B, 89C may or may not be constant.
The method of fixing the second fixing member 92 to the first fixing member 91 is not limited to the above method, and may be, for example, fastening by a screw.
The embodiments and modifications disclosed above can be combined with each other.
