As Figure 1 shown, the ring slider 1 of the present embodiment is used for hanging the window curtain 8, can move along the axial direction of the curtain rail 9, and is configured to be detachable from the curtain rail 9. In addition, the specific structures of the curtain 8 and the curtain rail 9 using the ring slider 1 are not particularly limited. The curtain 8 illustrated in the present embodiment includes a curtain cloth 81 and a plurality of washers 82 provided at the upper end portion of the curtain cloth 81. The curtain 8 is suspended and supported on the curtain rail 9 by the ring slider 1 passing through each washer 82. The curtain rail 9 illustrated in the present embodiment is, for example, a rod body whose both end portions are fixed to the wall surface such as a shower curtain rail. [Structure of ring slider 1] Mainly referring to Figure 2 the structure of the ring slider 1 will be described. The ring slider 1 is formed as an integral body from an elastic material such as synthetic resin. The ring slider 1 includes: a ring part 2 formed with an openable and closable opening part 21; a curtain holding part 3 provided on the ring part 2; a first leg part 41 and a second leg part 42 for opening and closing the opening part 21 of the ring part 2; and a handle part 5 provided on the ring part 2. The ring portion 2 extends in a ring shape so as to form a through hole 20 through which the curtain rail 9 passes. The ring portion 2 has an opening portion 21 formed by cutting a part of the ring shape of the ring portion 2. In other words, the ring portion 2 has a pair of opening end portions 22, 23, and the pair of opening end portions 22, 23 form the opening portion 21 communicating with the through hole 20. In addition, the ring portion 2 can elastically deform in such a manner that the pair of opening end portions 22, 23 approach each other to close the opening portion 21 (see Figure 3 ). As a specific structure, the ring portion 2 has the following parts: a ring main body portion 24 disposed along a circle or an ellipse centered on the central axis C; and a bent portion 25 bent outward from the ring main body portion 24. The ring main body portion 24 is formed with an inner peripheral surface 241 that can abut against the curtain rail 9. The range of the ring main body portion 24 in the ring portion 2 is divided by the bent portion 25. Hereinafter, the direction along the central axis C of the ring portion 2 is referred to as the axial direction, and the direction orthogonal to the central axis C is referred to as the radial direction. In addition, the central axis C of the ring portion 2 in the present embodiment can be determined as the center of the inner peripheral surface 241 of the ring main body portion 24. In addition, since the ring portion 2 in the present embodiment extends along a circle, hereinafter, the extending direction of the ring portion 2 is sometimes referred to as the circumferential direction. The cross-sectional shape orthogonal to the circumferential direction of the ring portion 2 is not particularly limited, and may be circular or rectangular. In addition, the respective dimensions in the radial and axial directions of the ring portion 2 are not particularly limited. In the present embodiment, the respective dimensions in the radial and axial directions of the ring portion 2 are set so that the ring portion 2 can pass through the washer 82 of the curtain 8. The curtain holding portion 3 is constituted by the bent portion 25 of the ring portion 2. That is, the curtain holding portion 3 is configured as a part in the circumferential direction of the ring portion 2, and a concave portion 251 is formed so as to be recessed with respect to the inner peripheral surface 241 of the ring main body portion 24. The curtain holding portion 3 can hold the arrangement of the washer 82 in the ring portion 2 in a state where the washer 82 of the curtain 8 is penetrated. Among them, the curtain holding portion 3 is provided at a position in the circumferential direction of the ring portion 2 that is separated from the opening end portions 22 and 23 of the ring portion 2 and is a position other than the portion opposite to the opening portion 21. In addition, as shown in Figure 3 , a first direction R1 from the central axis C of the ring portion 2 toward the closed opening portion 21 and a second direction R2 from the central axis C of the ring portion 2 toward the curtain holding portion 3 intersect with each other. For example, the first direction R1 and the second direction R2 preferably intersect at an angle of 60 degrees to 120 degrees, and more preferably intersect at an angle of 90 degrees. In other words, preferably, in a state where the curtain holding portion 3 is disposed on the lower side in the vertical direction with respect to the central axis C, the opening portion 21 of the ring portion 2 is disposed on one side in the horizontal direction with respect to the central axis C. In addition, the above-described first direction R1 can be defined as the direction passing through the intersection of the central axis C and a pair of open ends 22 and 23 of the ring portion 2 when observing the ring portion 2 from the axial direction. Further, the above-described second direction R2 can be defined as the direction passing through the central axis C and the holding position of the curtain 8 in the curtain holding portion 3 (the central portion in the circumferential direction of the curtain holding portion 3 in the present embodiment) when observing the ring portion 2 from the axial direction. The first leg portion 41 projects radially outward from the open end 22 of the ring portion 2, and the second leg portion 42 projects radially outward from the open end 23 of the ring portion 2. The first leg portion 41 and the second leg portion 42 are bent so as to be farther apart from each other toward the radially outer side, and when the ring portion 2 is elastically deformed, the first leg portion 41 and the second leg portion 42 can be in a "twisted configuration" in which they are twisted together. In the present embodiment, when the first leg portion 41 and the second leg portion 42 are in the twisted configuration, as Figure 3 shown, the base end portion 412 of the first leg portion 41 abuts against one side (the inner side of the paper surface) in the axial direction with respect to the open end 23 of the ring portion 2. Further, the first leg portion 41 and the second leg portion 42 cross each other in an alternating manner in the axial direction, and the tip end portion 411 of the first leg portion 41 abuts against the other side (the front side of the paper surface) in the axial direction with respect to the tip end portion 421 of the second leg portion 42. The ring slider 1 of the present embodiment has a groove structure adapted to the above-described twisted configuration formed by the first leg portion 41 and the second leg portion 42. Hereinafter, with reference to Figure 4 and Figure 5 it will be specifically described. In addition, in Figure 4 and Figure 5 for the sake of illustration, the center line M in the axial direction of the ring slider 1 is shown. As Figure 4 shown, the first leg portion 41 has: a tip groove portion 6A disposed at the tip end portion 411; a base end groove portion 7A disposed at the base end portion 412; and an intermediate portion 413 disposed between the tip groove portion 6A and the base end groove portion 7A in the extending direction of the first leg portion 41. The tip groove portion 6A and the base end groove portion 7A open to opposite sides in the axial direction. The tip groove portion 6A has a groove depth D1 equivalent to half of the thickness of the first leg portion 41 in the axial direction, and penetrates the first leg portion 41 along the width direction of the first leg portion 41 which is orthogonal to the extending direction and the axial direction of the first leg portion 41, respectively. Similarly, the base end groove portion 7A has a groove depth D2 equivalent to half of the thickness of the first leg portion 41 in the axial direction, and penetrates the first leg portion 41 along the width direction of the first leg portion 41. The wall portion of the tip groove portion 6A on the tip side of the first leg portion 41 may be missing. The groove width of the base end groove portion 7A is greater than the width of the ring portion 2 in the direction orthogonal to the extending direction and the axial direction of the ring portion 2, respectively. As Figure 5As shown, the second leg portion 42 has a top groove portion 6B configured to the top end portion 421, and the opening end portion 23 of the ring portion 2 has a base end groove portion 7B. Further, the second leg portion 42 has an intermediate portion 423 disposed between the top groove portion 6B and the base end groove portion 7B in the extending direction of the second leg portion 42. The top groove portion 6B and the base end groove portion 7B open to opposite sides in the axial direction. The top groove portion 6B has a groove depth D3 equivalent to half of the thickness of the second leg portion 42 in the axial direction, and penetrates the second leg portion 42 along the width direction of the second leg portion 42 which is orthogonal to the extending direction and the axial direction of the second leg portion 42 respectively. Similarly, the base end groove portion 7B has a groove depth D4 equivalent to half of the thickness of the ring portion 2 in the axial direction, and penetrates the ring portion 2 along the width direction of the ring portion 2. The wall portion of the top groove portion 6B located on the top end side of the second leg portion 42 may be missing. The groove width of the base end groove portion 7B is greater than or equal to the width of the first leg portion 41. In addition, the top groove portion 6A of the first leg portion 41 and the top groove portion 6B of the second leg portion 42 open to opposite sides in the axial direction, and the base end groove portion 7A of the first leg portion 41 and the base end groove portion 7B of the ring portion 2 open to opposite orientations in the axial direction. When the first leg portion 41 and the second leg portion 42 are torsionally disposed, as Figure 3 shown, the base end groove portion 7A of the first leg portion 41 and the base end groove portion 7B of the ring portion 2 are axially engaged with each other, and the top groove portion 6A of the first leg portion 41 and the top groove portion 6B of the ring portion 2 are axially engaged with each other. At this time, the wall surface of the base end groove portion 7A of the first leg portion 41 is radially engaged with the opening end portion 23 of the ring portion 2, the top end portion 411 of the first leg portion 41 is axially engaged with the top end portion 421 of the second leg portion 42, and the intermediate portion 413 of the first leg portion 41 is engaged with the intermediate portion 423 of the second leg portion 42 in the width direction of the opening portion 21. That is, the first leg portion 41 and the second leg portion 42 can achieve engagement in three directions of the radial direction, the axial direction, and the width direction of the opening portion 21 of the ring portion 2, and lock the closed state of the opening portion 21 of the ring portion 2. As Figure 2 shown, the handle portion 5 is integrally formed with the ring portion 2 and protrudes radially outward from a portion of the ring portion 2 opposite to the opening portion 21. Specifically, the handle portion 5 includes: a pair of side surface portions 511, 512 which are connected to the outer peripheral surface 242 of the ring main body portion 24 and extend in the axial direction; an R-shaped corner portion 52 formed between the pair of side surface portions 511, 512, and a pair of flat surface portions 531, 532 which are orthogonal to the axial direction. When viewed along the axial direction, the pair of side surface portions 511, 512 are disposed on different lines T1, T2 connected to the outer peripheral surface 242 of the ring main body portion 24. The corner portion 52 preferably has an angle of 90 degrees or more as the angle formed by the lines T1, T2. [Installation Method of Ring Slider] An example of the installation method of the ring slider 1 of the present embodiment will be described. First, the operator installs the curtain 8 on Figure 2 the curtain holding portion 3 (curtain installation process) of the ring slider 1 shown. At this time, the operator inserts the first leg portion 41 into the washer 82 of the curtain 8, and moves the washer 82 along the extending direction of the ring portion 2, so as to dispose the curtain 8 on the curtain holding portion 3. Next, after the operator holds the handle portion 5 with one hand, as Figure 6 shown by the arrow A1 in, the opening portion 21 of the ring portion 2 is pushed upward in the vertical direction with respect to the curtain rail 9 (pushing process). At this time, the first leg portion 41 and the second leg portion 42 guide the curtain rail 9 toward the opening portion 21 of the ring portion 2. In addition, the ring portion 2 receives the pushing force from the curtain rail 9 via the first leg portion 41 and the second leg portion 42, and elastically deforms in such a manner that the opening portion 21 becomes wider. Thereby, the curtain rail 9 passes through the opening portion 21 and becomes a state of being inserted into the ring portion 2. Further, during the pushing process, the curtain 8 held on the curtain holding portion 3 is disposed at a position separated from the opening portion 21 so as not to cover the opening portion 21 of the ring portion 2. Next, as Figure 7 shown by the arrow A2 in, the ring slider 1 is rotated (rotation process). Among them, no force of the operator is required for the rotation of the ring slider 1. That is, if the operator removes the hand from the handle portion 5, due to the load of the curtain 8 held on the curtain holding portion 3, a rotational torque centered on the curtain rail 9 is applied to the ring slider 1. Thereby, the ring slider 1 rotates around the curtain rail 9. At this time, the curtain rail 9 slides on the inner peripheral surface 241 of the ring portion 2. If the rotation of the ring slider 1 is completed, as Figure 8 shown in, the curtain holding portion 3 is disposed on the lower side in the vertical direction with respect to the curtain rail 9, and the opening portion 21 of the ring portion 2 is disposed on one side in the horizontal direction with respect to the curtain rail 9. After that, as Figure 8 shown by the arrow A3 in, the operator twists the first leg portion 41 and the second leg portion 42 with each other. Thereby, the first leg portion 41 and the second leg portion 42 are maintained in the above-mentioned twisted configuration, and the closed state of the opening portion 21 of the ring portion 2 is locked. Through the above steps, the installation of the ring slider 1 with respect to the curtain rail 9 is completed. In addition, in the case of replacing the curtain 8 or the like, when detaching the loop slider 1 from the curtain rail 9, the reverse order of the above-described method of installing the loop slider 1 may be performed. For example, after the opening 21 of the loop portion 2 is opened by operating the first leg portion 41 and the second leg portion 42, the handle portion 5 is pulled downward in the vertical direction. Thereby, the curtain rail 9 can pass through the opening 21 of the loop portion 2, and the loop slider 1 can be detached from the curtain rail 9. [Effects of the present embodiment] As described above, the loop slider 1 of the present embodiment includes: a loop portion 2 that extends in a ring shape so as to form a through hole 20 through which the curtain rail 9 passes; and a curtain holding portion 3 that is provided on the loop portion 2. The loop portion 2 has a pair of opening ends 22 and 23, and the pair of opening ends 22 and 23 form an opening 21 that communicates with the through hole 20. The opening 21 of the loop portion 2 is opened and closed by elastic deformation of the loop portion 2. A first direction R1 from the central axis C of the loop portion 2 toward the opening 21 in the closed state and a second direction R2 from the central axis C of the loop portion 2 toward the curtain holding portion 3 intersect each other. In the above structure, the curtain rail 9 can be inserted into or removed from the loop portion 2 via the opening 21 of the loop portion 2, so that the loop slider 1 can be attached to and detached from the curtain rail 9. In addition, during the attachment and detachment operation of the loop slider 1, the curtain 8 attached to the curtain holding portion 3 is less likely to interfere with the opening 21 of the loop portion 2. Therefore, the attachment and detachment operation of the loop slider 1 with respect to the curtain rail 9 becomes easy. In addition, after the loop slider 1 is attached to the curtain rail 9, in a state where the weight of the curtain 8 is applied to the curtain holding portion 3, it is possible to prevent the opening 21 of the loop portion 2 from being disposed on the upper side in the vertical direction with respect to the curtain rail 9. Thus, without a structure for firmly closing the opening 21 of the loop portion 2, it is possible to prevent the loop slider 1 from falling off the curtain rail 9. Therefore, the ease of the attachment and detachment operation of the loop slider 1 is not impaired. Therefore, according to the loop slider 1 of the present embodiment, even when the curtain 8 is installed, the attachment and detachment operation with respect to the curtain rail 9 can be easily performed. In the present embodiment, the curtain holding portion 3 is provided separately from the pair of opening ends 22 and 23 in the extending direction of the loop portion 2 at a portion of the loop portion 2 other than the portion opposite to the opening 21. According to the above structure, even when the opening 21 of the loop portion 2 is in an open state, it is possible to prevent the loop slider 1 from falling off the curtain rail 9. For example, it is possible to prevent the loop slider 1 from accidentally falling off during the attachment and detachment operation of the loop slider 1 with respect to the curtain rail 9. Therefore, the operator can temporarily release the loop slider 1. Therefore, the attachment operation of the loop slider 1 with respect to the curtain rail 9 becomes easier. In the present embodiment, the curtain holding portion 3 is configured as a bent portion 25 that is a part of the ring portion 2, and a concave portion 251 is formed that is recessed with respect to a portion of the inner peripheral surface 241 of the ring portion 2 other than the bent portion 25. In the above structure, the curtain holding portion 3 can hold the curtain 8 through the washer 82 that penetrates the curtain 8. That is, the ring slider 1 can directly hold the curtain 8 without the help of other hooks or the like. Thereby, the structure of the curtain holding portion 3 can be simplified. The ring slider 1 of the present embodiment further includes a handle portion 5 provided on the ring portion 2, and the handle portion 5 protrudes outward from the ring portion 2 at a position opposite to the opening portion 21 in the ring portion 2. In the above structure, when disassembling and assembling the ring slider 1 with respect to the curtain rail 9, an operator can appropriately apply a force to the ring portion 2. Therefore, the installation operation of the ring slider 1 with respect to the curtain rail 9 becomes easier. In the present embodiment, the handle portion 5 has: a pair of side faces 511, 512 that are arranged on different lines T1, T2 connected to the outer peripheral surface 242 of the ring portion 2; and a corner portion 52 that is formed between the pair of side faces 511, 512. According to the above structure, the handle portion 5 can strengthen the elastic force when the opening portion 21 of the ring portion 2 is opened and closed. In the present embodiment, in a state where the curtain holding portion 3 is arranged on the lower side in the vertical direction with respect to the central axis C, the opening portion 21 of the ring portion 2 is arranged on one side in the horizontal direction with respect to the central axis C. According to the above structure, it is possible to appropriately balance the suppression of the interference of the curtain 8 with the disassembly and assembly operation of the ring slider 1 and the suppression of the detachment of the ring slider 1. In the present embodiment, the inner peripheral surface 241 of the ring portion 2 is continuously bent at least from the opening portion 21 to the portion opposite to the curtain holding portion 3. According to the above structure, during the disassembly and assembly operation of the ring slider 1, the rotation of the ring portion 2 with respect to the curtain rail 9 is not hindered. Therefore, the disassembly and assembly operation of the ring slider 1 can be easily performed. The ring slider 1 of the present embodiment further includes a first leg portion 41 and a second leg portion 42 that extend from a pair of opening ends 22, 23 of the ring portion 2 to the side opposite to the through hole 20 side, and the first leg portion 41 and the second leg portion 42 are torsionally arranged with respect to each other by the elastic deformation of the ring portion 2. In the above structure, by operating the first leg portion 41 and the second leg portion 42, the opening and closing operation of the opening portion 21 of the ring portion 2 can be performed. In addition, an operator can operate the first leg portion 41 and the second leg portion 42 with one hand. In addition, in the prior art such as the above-mentioned Patent Document 1, a pair of opening ends of the ring portion are configured to have both a closing function for closing the opening portion of the ring portion and a curtain holding function, thus complicating the structure. On the other hand, in the present embodiment, a first leg portion 41, a second leg portion 42 for closing the opening portion 21 of the ring portion 2, and a curtain holding portion 3 are respectively formed, so that the structures of both can be simplified respectively, and the strength can be improved. In the present embodiment, the base end portion 412 of the first leg portion 41 and the opening end portion 23 of the ring portion 2 connected to the second leg portion 42 have base end groove portions 7A, 7B that open toward each other in the axial direction, and when the first leg portion 41 and the second leg portion 42 are torsionally arranged, the base end groove portion 7A of the first leg portion 41 and the base end groove portion 7B of the opening end portion 23 are axially engaged with each other. In such a structure, when the first leg portion 41 and the second leg portion 42 are torsionally arranged, an increase in the axial thickness of the ring slider 1 can be suppressed, and at the same time, the state where the opening portion 21 is properly closed can be maintained. In the present embodiment, the tip end portions 411, 421 of the first leg portion 41 and the second leg portion 42 have tip end groove portions 6A, 6B that open in opposite directions in the axial direction of the ring portion 2, and when the first leg portion 41 and the second leg portion 42 are torsionally arranged, the tip end groove portion 6A of the first leg portion 41 and the tip end groove portion 6B of the second leg portion 42 are axially engaged with each other. In the above structure, when the first leg portion 41 and the second leg portion 42 are torsionally arranged, an increase in the axial thickness of the ring slider 1 can be suppressed, and at the same time, the state where the opening portion 21 is properly closed can be maintained [Modification Example] In the above embodiment, the ring slider 1 is mounted on the curtain 8 through the through-washer 82, but the present invention is not limited thereto. For example, the ring slider 1 can also be mounted on a curtain in any form by means of other members such as hooks. In this case, after the ring slider 1 is mounted on the curtain rail 9, the hook can also be hooked on the curtain holding portion 3. The ring portion 2 of the above embodiment has a substantially circular ring shape, but the present invention is not limited thereto. For example, the ring shape of the ring portion 2 can also have any shape such as an ellipse or a polygon. The curtain holding portion 3 of the above embodiment is integrally formed with the ring portion 2, but the present invention is not limited thereto. For example, the curtain holding portion 3 can also be formed separately from the ring portion 2 and mounted on the ring portion 2. The ring slider 1 of the above-described embodiment includes the first leg portion 41 and the second leg portion 42 as structures for maintaining the opening portion 21 of the ring portion 2 in the closed state, but the present invention is not limited thereto. For example, the ring slider 1 may not include the first leg portion 41 and the second leg portion 42, and may have other structures for closing the opening portion 21 of the ring portion 2. The ring slider 1 of the above-described embodiment includes the handle portion 5 as a structure for an operator to hold, but the present invention is not limited thereto. For example, the ring slider 1 may not include the handle portion 5, and may have other structures for an operator to hold.
