Abstract

<P>PROBLEM TO BE SOLVED: To provide a ring member aligning device capable of surely unraveling an entwined ring member. <P>SOLUTION: When a snap ring vertically moving part 39 reaches a top point of a cylindrical rotating body 34, a snap ring 70 gets on a slope, and thereby a pressing roller 40 is slightly pushed up from a lower side, and the relative position in relation to baffle plates 44a is deviated upward as compared with a time before the snap ring 70 gets on the slope. Since the plurality of baffle plates 44a forming a comb-tooth unraveling part 44 are stood at intervals, the snap ring 70 has to get over the baffle plates 44a one by one from a base end side toward a distal end side. Thus, the snap ring 70 moves to an outlet, while an outer peripheral edge of the snap ring 70 is caught by the baffle plates 44a of the comb-tooth unraveling part 44 or the snap ring 70 is pressed from the above by the pressing roller 40. As a result, entwining is easy to be unraveled since the moving speed becomes slower as compared with time when the snap ring 70 approaches to the slope part. <P>COPYRIGHT: (C)2007,JPO&INPIT

JP 2004-90179 A

  However, the tangled ring member may not be unraveled simply by feeding the ring member to the outlet side along the spiral shape of the spring by rotating the shaft. For this reason, development of the apparatus which can loosen the entangled ring member reliably was desired.

  The ring member aligning device of the present invention has an object to reliably loosen the entangled ring member. Another object of the ring member alignment apparatus of the present invention is to align and align the cut ends of the ring member having cut ends.

  The present invention employs the following means in order to achieve at least a part of the above-described object.

The ring member alignment apparatus of the present invention is
A ring member alignment device for separating and aligning entangled ring members one by one,
Power generation means;
The ring member can be inserted and has a spiral groove, and as the shaft is rotated by the power of the power generating means, the ring member is moved toward the outlet, and the ring member is moved to one by the spiral groove. A rotating body that sends out one by one,
A plurality of regulating means capable of coming into contact with the outer peripheral edge of the ring member when the ring member inserted into the rotating body moves toward the outlet;
It is a summary to provide.

  In this ring member aligning device, when a plurality of entangled ring members are inserted into the rotating body and then the rotating body is axially rotated by the power of the power generating means, the ring member moves toward the outlet. Moreover, in the location where the spiral groove is provided, the ring members are sent one by one toward the outlet by the spiral groove. And while the ring member moves toward the outlet, its outer peripheral edge moves while being caught by a plurality of regulating means, the movement of the ring member becomes irregular, and the entanglement is easily loosened. The loose ring member does not become a lump. Therefore, the entangled ring member can be loosened more securely than in the case where there is no such restricting means.

  The ring member alignment apparatus of the present invention includes a pressing unit that is disposed on the opposite side across the plurality of regulating units and the rotating body, and that presses the ring member inserted into the rotating body inward in the radial direction of the rotating body. It may be provided. In this way, the ring member does not float when the outer peripheral edge moves while being caught by the plurality of regulating means.

  In the ring member alignment device of the present invention, the plurality of restricting means may be uneven in height. In this way, the degree to which the ring member gets caught by the restricting means varies depending on the height of the restricting means, so that the movement of the ring member moving toward the outlet becomes irregular, the entanglement tends to be loosened, and once loosened The ring member does not become a lump. For example, at least some of the plurality of regulating means may be arranged so that the height gradually decreases after being arranged so as to gradually become taller toward the outlet.

  In the ring member alignment device of the present invention, the rotating body may have a central axis inclined downward toward the outlet. If it carries out like this, the ring member inserted in the rotary body will move easily toward an exit.

  The ring member alignment apparatus of the present invention may include a ring member vertical movement means for moving the ring member inserted into the rotary body up and down as the rotary body rotates about the axis. By doing so, the ring member can be swung in the vertical direction, so that the entanglement is more easily loosened. In particular, in the case where the pressing means is provided, the strength of the pressing force changes by moving the ring member up and down, so that the entanglement is further easily loosened.

  In the ring member aligning apparatus of the present invention having such a ring member vertical movement means, the ring member vertical movement means has a portion where the distance from the rotation center of the rotating body to the outer peripheral surface of the rotating body is long and a short portion. It may be provided in this rotary body. For example, the ring member vertical movement means protrudes from the outer peripheral surface of the rotating body along the central axis of the rotating body and temporarily moves the ring member inserted into the rotating body as the rotating body rotates axially. It may be lifted up.

  The ring member aligning device of the present invention may include ring member hitting means for hitting a ring member inserted into the rotating body by a swinging member supported so as to be swingable to the side of the rotating body. If it carries out like this, even if a plurality of entangled ring members are struck by the ring member hitting means, the entanglement is easily loosened.

  In the ring member alignment device of the present invention including such a ring member hitting means, the ring member hitting means includes the swinging member, and a biasing member that biases the swinging member in a direction approaching the rotating body, An oscillating plate pressing member that protrudes radially outward from the outer peripheral surface of the rotator and presses the oscillating member away from the rotator as the rotator rotates. It may be a thing. If it carries out like this, a ring member can be hit with a rocking | fluctuation member according to rotation of a rotary body.

  Further, in the ring member aligning apparatus of the present invention provided with such a ring member hitting means, the ring member hitting means may be provided on both the left and right sides of the rotating body. By doing so, the ring member can be hit from both the left and right sides, so that the entanglement is more easily loosened. At this time, the interval between the rocking members on the left and right sides of the rotating body may be widened toward the outlet of the rotating body. If it carries out like this, a part of force in which a rocking | swiveling member strikes a ring member will become a driving force when moving a ring member toward an exit.

  In the ring member alignment apparatus of the present invention, the ring member may be a member that is cut at one portion of the ring. Since the ring member having such a cut is tangled more easily than the ring member having no cut, the significance of applying the present invention is high. Examples of the ring member having a cut end include a substantially C-shaped snap ring.

  The ring member aligning device of the present invention for loosening the entanglement of the ring member having such a cut and separating the ring members one by one is provided at a position facing at least a part of the spiral portion. It is good also as what equips the cut of the said ring member sent out toward the said exit by this, and equips it with the cut end alignment means which aligns a cut. In this way, the ring members are not only separated one by one by untangling, but are aligned with the cut ends aligned.

  Next, the best mode for carrying out the present invention will be described using examples.

  FIG. 1 is a side view of a snap ring aligning device 20 as an embodiment of the present invention, and FIG. 2 is a front view of the snap ring aligning device 20.

  The snap ring aligning device 20 of the present embodiment is a device used when separating and aligning a plurality of entangled snap rings 70 one by one. As shown in FIG. 10, the snap ring 70 is a member that has a cut 72 formed by cutting one part of the ring. As shown in FIG. 1, the snap ring aligning device 20 includes a motor 30 as power generation means, a columnar rotating body 34 that is axially rotated by the motor 30, and a press disposed above the columnar rotating body 34. A pressing roller 40 as means, a comb-teeth unraveling portion 44 in which a plurality of baffle plates 44a as restricting means are arranged below the cylindrical rotating body 34, and a ring supported swingably on both left and right sides of the cylindrical rotating body 34 A snap ring hitting member 50 (see FIG. 2) as a member hitting means and a cut aligning plate 46 as a cut aligning means for aligning the cut 72 of the snap ring 70 inserted into the cylindrical rotating body 34 are provided.

  As shown in FIG. 1, the motor 30 is mounted on the back surface of the component mounting plate 24 supported by the rotating shaft 24 b of the bearing bracket 24 a on the base plate 22 via the motor bracket 26. Further, the component mounting plate 24 is prevented from rotating clockwise on the front side, that is, in FIG. 1, about the rotation shaft 24b, but is set to a predetermined angle (for example, 30 °) on the back side, that is, counterclockwise. It is allowed to rotate by 40 °).

  The cylindrical rotating body 34 is attached to the front surface of the component mounting plate 24, and rotates axially with the rotation of the driven gear 36 disposed on the back surface of the component mounting plate 24. Here, the driven gear 36 is meshed with the drive gear 32 integrated with the rotation shaft of the motor 30. For this reason, the columnar rotating body 34 is axially rotated by the motor 30. Further, regarding the cylindrical rotating body 34, the left side in FIG. 1 is referred to as a proximal end, and the right side is referred to as a distal end (also referred to as an outlet). The cylindrical rotating body 34 is formed with a cylindrical portion 34a, a screw portion 34b, and a tapered portion 34c from the base end to the tip, and the central axis CL is slightly inclined downward from the base end toward the tip. For this reason, the component force in the direction along the central axis CL of the cylindrical portion 34a in the load of the snap ring 70 inserted into the columnar rotating body 34 works as a force for moving the snap ring 70 toward the outlet. In the cylindrical portion 34a, a snap ring vertical movement portion 39 composed of a pair of ridges 39a extending along the central axis CL is formed at two locations with a circumferential angle of about 180 °. The protrusion 39a forming the snap ring vertical movement portion 39 is formed at a substantially constant height from the base end side to the middle, but the section from the middle to the screw portion 34b is gently descending. It is formed to be a slope. A stay 37 protruding outward in the radial direction of the cylindrical portion 34a is formed on the base end side of the peripheral surface of the cylindrical portion 34a, and a swing plate of the snap ring hitting member 50 is formed at the tip of the stay 37. A swinging plate pressing roller 38 for swinging 54 is attached so as to be rotatable. The threaded portion 34b has a spiral groove whose pitch is substantially the same as the thickness of the snap ring 70. The taper portion 34c is provided to slide down the snap ring 70 after passing through the screw portion 34b.

  The pressure roller 40 is attached to a roller support bar 42 supported by a rotation shaft 42a provided on a roller attachment bracket 28 extending in the horizontal direction from the upper end of the component attachment plate 24 so as to be rotatable. Since the base end of the roller support bar 42 is in contact with a stopper 42b provided on the roller mounting bracket 28, the position shown in FIG. 1, that is, the state in which the pressing roller 40 is substantially parallel to the cylindrical rotating body 34. Although the clockwise rotation is prevented, the pressing roller 40 is allowed to rotate counterclockwise, that is, upward by a predetermined angle (for example, 20 ° or 30 °) from this state. Further, the pressing roller 40 is disposed so as to extend from the cylindrical portion 34 a to the screw portion 34 b in the upper space of the columnar rotating body 34.

  The comb-teeth unraveling portion 44 is formed by arranging a plurality of baffle plates 44a at intervals on the base plate 22. The plurality of baffle plates 44a are arranged so that the back is gradually lowered from the base end side toward the distal end side, that is, the outlet side, and the back is lowered. Finally, the tallest one is erected. Has been. The comb-teeth unraveling portion 44 is formed so as to come into contact with the outer peripheral edge of the snap ring 70 when the snap ring 70 inserted into the columnar rotating body 34 reaches the screw portion 34b from the cylindrical portion 34a.

  As shown in FIG. 2, the snap ring hitting member 50 is a pair of swinging members supported by stays 52, 52 provided on the left and right sides of the columnar rotating body 34 of the base plate 22 via swinging shafts 52a, 52a. The plates 54 and 54, the spring 56 that urges the pair of swing plates 54 and 54 toward each other, and the outer periphery of the columnar rotating body 34 protrude outward in the radial direction to rotate the columnar rotating body 34. Along with this, the oscillating plate 54 is pressed by a oscillating plate pressing roller 38 that presses the oscillating plate 54 away from the cylindrical rotating body 34 and then releases the pressing. Each swing plate 54 has a frame portion 54a whose lower end is supported by the stay 52, and a tapping portion that is connected to the frame portion 54a and bent so that the distance from the cylindrical rotating body 34 gradually increases upward. 54b. The swing plate 54 is prevented from rotating from a position standing substantially perpendicular to the base plate 22 (position shown in FIG. 2) toward the column rotating body 34 by a stopper (not shown). It is allowed to swing in a direction away from the rotating body 34. For this reason, the pair of swing plates 54, 54 are maintained in a state of being substantially vertical with respect to the base plate 22 by being biased toward each other by the spring 56. The pair of tapping parts 54b are arranged at positions where the snap ring 70 inserted into the cylindrical rotating body 34 can be contacted from both the left and right sides, and swinging that rotates as the cylindrical rotating body 34 rotates axially. After being pressed away from the rotating body 34 by the plate pressing roller 38, the pressing is released. The hitting and unwinding portion 54b is formed to have a size capable of hitting the snap ring 70 in the section from the base end of the cylindrical rotating body 34 to the tip (or midway of the screw portion 34b). Moreover, the space | interval of a pair of right and left tapping parts 54b and 54b has spread toward the exit.

  As shown in FIGS. 1 and 2, the cut alignment plate 46 is a plate standing on the base plate 22, and the cut ring 72 is inserted before the snap ring 70 inserted into the cylindrical rotating body 34 passes through the screw portion 34b. It arrange | positions so that one end may be contacted. The cut end alignment plate 46 also serves as a bearing bracket for the rotating body support roller 48 that supports the tip of the cylindrical rotating body 34 from below.

  Next, a procedure for separating and aligning a plurality of entangled snap rings 70 one by one using the snap ring aligning device 20 configured as described above will be described. 3-8 is explanatory drawing showing this work procedure. First, the operator grasps the roller support rod 42 and pulls it upward. Then, as shown in FIG. 3, the roller support bar 42 rotates counterclockwise by a predetermined angle (for example, 20 ° or 30 °) about the rotation shaft 42a, and then the roller mounting bracket 28 and the component mounting plate. 24 is rotated counterclockwise by a predetermined angle (for example, 30 ° or 40 °) around the rotation shaft 24b.

  Subsequently, a plurality of entangled snap rings 70 are inserted into the cylindrical portion 34a of the columnar rotating body 34, the roller support rod 42 is returned to the original position, a switch (not shown) of the motor 30 is turned on, and the motor 30 rotates the columnar rotating body. 34 is rotated. Then, as shown in FIG. 4, the swinging plate 54 is pressed after being pressed away from the columnar rotating body 34 by the swinging plate pressing roller 38 that rotates as the columnar rotating body 34 rotates. To release. Here, of the pair of swing plates 54, 54, one swing plate 54 (the right swing plate 54 in FIG. 4) is pressed in a direction away from the cylindrical rotating body 34 by the swing plate pressing roller 38. In some cases, the other swing plate 54 (the left swing plate 54 in FIG. 4) receives a force in a direction approaching the column rotating body 34 by the action of the spring 56, but rotates toward the column rotating body 34. Since it is blocked by the stopper that does not, it remains substantially perpendicular to the base plate 22 as shown in FIG. When the pressing by the swing plate pressing roller 38 to one swing plate 54 is released, the swing plate 54 returns to the original position by the biasing force of the spring 56, and at that time, the tapping and unwinding portion 54 b hits the right side of the snap ring 70. Further, when the columnar rotating body 34 rotates about half a half from the position of FIG. 4, the swinging plate pressing roller 38 presses the other swinging plate 54 and then releases the pressing, so that the hitting and unwinding portion 54b is moved to the snap ring 70. Hit the left side of Therefore, the snap rings 70 inserted in the columnar rotating body 34 that are shifted in the left-right direction are struck from both the left and right sides by the hitting and unwinding portion 54b of the swing plate 54 each time the columnar rotating body 34 makes one rotation. As a result, the shift in the left-right direction is corrected. On the other hand, since the snap ring vertical movement portion 39 is formed at two positions that form the diagonal of the columnar rotating body 34, it reaches the uppermost point of the columnar rotating body 34 every time the columnar rotating body 34 rotates approximately half a turn. Become. As shown in FIG. 5, each time the snap ring vertical movement part 39 reaches the uppermost point of the cylindrical rotary body 34, the snap ring 70 inserted into the cylindrical rotary body 34 is lifted by the height of the snap ring vertical movement part 39. Then, after the snap ring up-and-down moving part 39 passes the uppermost point, it is lowered by the height as shown in FIG. Accordingly, among the snap rings 70 inserted in the columnar rotating body 34, those that are shifted in the vertical direction are vertically moved by the vertical movement operation by the snap ring vertical movement unit 39 every time the columnar rotating body 34 rotates half a turn. Misalignment is corrected. In the snap ring 70 inserted into the columnar rotating body 34, the component force in the direction along the central axis CL (inclined downward toward the outlet) of the cylindrical portion 34a of the own load moves toward the outlet. Since it works as a propulsive force, the cylindrical portion 34a is gradually moved toward the outlet while being hit from the left-right direction or moved up and down in the vertical direction. In addition, since the distance between the pair of left and right tapping parts 54b and 54b gradually increases toward the outlet, the snap ring 70 also uses the cylindrical part 34a as the outlet even when the tapping part 54b strikes the snap ring 70. Move towards.

  Thereafter, when the snap ring 70 reaches the slope portion of the snap ring vertical movement portion 39 (the portion of the cylindrical portion 34a close to the screw portion 34b), the outer peripheral edge of the snap ring 70 loosens the comb teeth as shown in FIG. The baffle plate 44a of the part 44 is contacted. When the snap ring vertical movement portion 39 reaches the uppermost point of the cylindrical rotating body 34 (see the dotted line in FIG. 7), the snap ring 70 is on the slope. The relative position with respect to the baffle plate 44a is shifted upward compared to before the vertical movement portion 39 reaches the highest point. Here, when the snap ring 70 pushes up the pressing roller 40 from below, in other words, it can be said that the pressing roller 40 presses the snap ring 70 from above, and the pressing force causes the cylindrical rotating body 34 to rotate. The strength changes with the change. Further, since a plurality of baffle plates 44a forming the comb-teeth unraveling portion 44 are erected at intervals, the snap ring 70 has to go over the baffle plate 44a one by one from the proximal end side toward the distal end side. Don't be. In this way, the outer peripheral edge of the snap ring 70 moves toward the outlet while being caught by the baffle plate 44a of the comb-teeth unraveling portion 44 or being pressed from above by the pressing roller 40, so that it approaches the slope portion. Compared to before, the movement speed becomes slower or irregular, and the entanglement is easily loosened. In this embodiment, the arrangement of the plurality of baffle plates 44a is such that the height is gradually increased from the base end side, and then the height is gradually decreased. Was the tallest. This arrangement is the result of carrying out an experiment for confirming the loosening of the entanglement when the entangled snap ring 70 is inserted into the cylindrical rotating body 34 and the cylindrical rotating body 34 is axially rotated with respect to various arrangements. Is the sequence when.

  Thus, the snap ring 70 that has passed through the comb-teeth unraveling portion 44 reaches the screw portion 34 b of the cylindrical rotating body 34. Then, as shown in FIG. 8, the snap ring 70 enters the spiral groove of the screw portion 34b, and is aligned one by one along the spiral groove along the spiral groove as the cylindrical rotating body 34 rotates. Sent out. At this time, the snap ring 70 itself also moves toward the outlet while rotating. When the snap ring 70 reaches the portion near the tapered portion 34c of the screw portion 34b, one end of the cut 72 comes into contact with the cut alignment plate 46 disposed below the snap ring 70, and thereafter The screw part 34b is moved toward the outlet while maintaining the posture. Therefore, the snap ring 70 at the time of passing through the screw portion 34b is in a state of being aligned such that the cut end 72 is at a predetermined position.

  Although not described in FIGS. 1 to 8, the snap ring alignment device 20 is connected to the tapered portion 34 c of the cylindrical rotating body 34 and sends the snap ring 70 to the ring extraction mechanism 80 as shown in FIG. 9. A ring slide 60 and a cut position alignment table 62 that is connected to the cut alignment plate 46 and enters the cut 72 of the snap ring 70 to align the cut 72 are attached. The ring slide 60 is inclined downward toward the tip, and slides downward while supporting the inner peripheral edge of the snap ring 70 at three points. Further, as shown in a cross-sectional view when the cross section taken along the horizontal plane in the circle of FIG. 9 is viewed from above, the cut end alignment base 62 becomes wider toward the tip, and finally from one end of the cut end 72. It is formed to have the same width as the distance to the other end. Therefore, the snap ring 70 that slides down the ring slide base 60 is restrained in front of the ring take-out mechanism 80. At this time, the cut end alignment base 62 is in a posture such that the cut end 72 faces directly below. Here, the ring take-off mechanism 80 can receive the snap ring 70 that has slid the ring slide 60 and stop it, and the snap ring 70 that is stopped by the ring stop portion 86 can be received and shaken. A seesaw 82 supported by the moving shaft 82c and a blade 88 disposed above the tip 82a of the seesaw 82 are provided. The blade 88 is fixed to a scissor portion 66 in which an upper end of a support column 64 erected on the side of the ring slide base 60 and the cut end alignment base 62 is bent upward of the ring slide base 60. The seesaw 82 is normally connected to the tip 82a of the seesaw 82 by the elastic force of a spring 82e installed between a spring receiving portion 82d formed at the base end 82b and a bracket 84 provided with a ring stopper 86 at the upper end. The leading end of the blade 88 is substantially coincident with the leading end of the blade 88. In this state, the leading snap ring 70 of the plurality of snap rings 70 restrained by the ring restraining portion 86 rides on the base end 82b of the seesaw 82. The swing shaft 82 c is provided on a bearing bracket 85 integrated with the bracket 84. Now, as shown in FIG. 9, it is assumed that one snap ring 70 is suspended from the tip 82 a of the seesaw 82. In this state, the snap ring 70 suspended from the tip 82a of the seesaw 82 is held and quickly pulled down. Then, the tip 82a of the seesaw 82 moves downward about the swinging shaft 82c so that the snap ring 70 comes out of the tip 82a of the seesaw 82, and the snap ring 70 on the base end 82b moves to the tip 82a. Thereafter, the state of FIG. 9 is restored again by the elastic force of the spring 82e. In this way, the snap rings 70 can be taken out one by one as needed by the ring take-out mechanism 80.

  According to the snap ring aligning device 20 described in detail above, when the plurality of tangled snap rings 70 are inserted into the cylindrical rotating body 34 and then the cylindrical rotating body 34 is axially rotated by the power of the motor 30, the snap ring 70 moves toward the outlet. While the snap ring 70 is moving toward the outlet, the pressing roller 40 is pressed from the upper side in the radial direction of the cylindrical rotating body 34 or the outer peripheral edge of the snap ring 70 has a plurality of baffle plates. Since it moves while catching on 44a, the entangled snap rings 70 can be loosened one by one. In addition, since the plurality of baffle plates 44a are uneven in height, the movement of the snap ring 70 moving toward the exit becomes irregular, and the entanglement is easily loosened. There is no lump. Further, the plurality of entangled snap rings 70 are struck by the unwinding portion 54b from both the left and right sides when being moved in the cylindrical portion 34a and are shaken in the vertical direction by the snap ring vertical movement portion 39. Misalignment is corrected. Further, after passing through the threaded portion 34b, the snap ring 70 is not only loosened and separated one by one, but also the cut 72 is aligned by the cut alignment plate 46. Furthermore, since all the driving sources are only the motor 30, the apparatus configuration is simpler than the case of using a plurality of motors.

  In the snap ring aligning device 20 of the embodiment, the plurality of baffle plates 44a are arranged so that the height of the baffle plates 44a is a mountain shape in a part of the comb-teeth unraveling portion 44 (that is, the region excluding the baffle plate 44a on the most outlet side) For example, the baffle plates 44a may be arranged so as to gradually increase in height toward the outlet in this region, or the high and low ones are arranged alternately. Alternatively, it may be arranged so that the height is random.

  In the snap ring aligning device 20 of the embodiment, the pressing roller 40 is used. However, the pressing roller 40 is omitted if the tangled snap ring 70 is effectively loosened even if the pressing ring 40 does not press the snap ring 70. May be.

  In the snap ring aligning device 20 of the embodiment, the snap ring vertical movement portion 39 made of the ridge 39a is adopted on the outer peripheral surface of the circular column rotating body 34 having a circular cross section, but the cross section is polygonal without providing such a ridge. You may make it move the snap ring 70 up and down by employ | adopting the rotary body 34 and rotating this.

In the snap ring aligning apparatus 20 of the embodiment, the rocking plate 54 is pressed by the rocking plate pressing roller 38 and then released, so that the snap ring 70 is hit by the hitting and unwinding portion 54b of the rocking plate 54. However, instead of the oscillating plate pressing roller 38, an eccentric cam 102 shown in FIG. 11 is provided for each oscillating plate 54 in a gear interlocking with the drive gear 32 of the motor 30, and each time the eccentric cam 102 makes one rotation. The swing plate 54 may be pressed and released.
In the snap ring aligning device 20 of the embodiment, a pair of left and right swing plates 54, 54 are connected by a spring 56. Instead of the spring 56, the swing plate 54 is moved for each swing plate 54 as shown in FIG. A spring 156 that urges the plate 54 in the direction toward the cylindrical rotating body 34 may be provided.

  In the snap ring aligning device 20 of the embodiment, the case where the substantially C-shaped snap ring 70 having the cut 72 as the ring member is aligned has been illustrated. However, the ring member such as the O shape having no cut is aligned as the ring member. In some cases, the snap ring aligning device 20 may be used.

  The best mode for carrying out the present invention has been described with reference to the embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the gist of the present invention. Of course, it can be implemented in the form.

  The present invention can be used when assembling various machines, instruments, devices, and other articles using a ring member such as a snap ring. For example, the present invention can be used in the fields of automobiles, motorcycles, railway vehicles, aircrafts, and the like. is there.
