DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lappet used for a spinning machine such as a ring spinning machine, a ring twisting machine and a drawing twisting machine.

[0002]

2. Description of the Related Art Generally, in this type of spinning machine, in order to form a thread, the ring rail is gradually raised while repeatedly moving up and down the ring rail while the machine is in operation, and the lappet angle and the balloon control are synchronized with the movement. Raise and lower the ring etc. The wrappet plays a role in guiding the yarn while maintaining the ballooning center of the yarn sent from the roller part on an extension of the rotation center of the bobbin. When a yarn break occurs during spinning, the operator performs splicing, and the operator needs to pull out the bobbin fitted to the spindle from the spindle to perform the splicing operation. Therefore, it is necessary to arrange the lappets at the retreat position which does not hinder the work for each weight, and to rotate the lappets of all the weights simultaneously to the retreat position at the time of doffing work.

[0003] In order to satisfy the above-mentioned requirements, generally, a lappet is placed in a horizontal state (spinning position) for each weight with respect to a lappet angle which is arranged rotatably in parallel with a spindle rail. It is rotatably attached to the retracted position that has been pivoted upward (for example, an actual open flat 4-7).
No. 8279). However, when rotating the lappet angle from the spinning position to the doffing position by applying a rotating force at one end of the lappet angle, the twisting generated in the lappet angle is reduced to be away from the side to which the rotating force is applied. It is necessary to move the lappet assembled in the position to a position where it does not hinder the doffing operation. But,
In the case of a lappet angle with an L-shaped cross section, the torsional rigidity is small and the number of weights is large compared to the case of using a round pipe or a round rod with the same installation space due to the second moment of area. Cause trouble. Further, in order to rotatably support the lappet angle with respect to the machine base, it is necessary to support the lappet angle via a support shaft, and the configuration for supporting the lappet angle becomes complicated. Further, the lappet angle becomes long in a machine having a large number of weights, and the structure becomes more complicated when the lappet angle is rotatably supported even at an intermediate portion in order to prevent its bending.

[0004] As a lappet that solves the above-mentioned disadvantages when a lappet angle is used, Japanese Utility Model Application Laid-Open No. 63-7180 is disclosed.
In the publication, as shown in FIG. 19, a lappet 41 is replaced with a lappet angle, and a pipe (circular pipe) 4 having a circular section is used.
2 is disclosed. More specifically, the lappet 41 includes a lappet main body 43 and a regulating ring 44. The lappet main body 43 is rotatably supported by the round pipe 42 at a pair of ring portions 43a, and has a snell wire 45 at the tip. I have.
The restriction ring 44 is fixed to the round pipe 42 between the two ring portions 43a, and restricts movement of the lappet body 43 in the axial direction. The restricting ring 44 receives the lappet main body 43 in the use posture (spinning position) and the receiving portion 46, and when the lappet main body 43 is rotated upward, engages with the lappet main body 43 to restrict the rotation. Receiving part 4
7 is provided. The regulating ring 44 is screwed 48
Thereby, it is fixed at a predetermined position of the round pipe 42.

[0005] The torsional rigidity of the round pipe 42 or the rod having a circular cross section is greater than that of a lappet angle requiring the same arrangement space. As a result, at the time of doffing, when a rotating force is applied to one end side of the round pipe 42 or the rod having a circular cross section to rotate to the doffing position, the lappet 4 having the full weight is
1 is arranged in a position where it does not hinder doffing.

FIG. 20 shows a configuration of a lappet conventionally used in a spinning machine. In the figure, a lappet 41 is inserted into a pipe 42 for mounting a lappet and then fixed using screws 48, and swings by a lappet support section 49 similarly inserted into the pipe 42. Lappet movable part 5 whose range is regulated
It is mainly configured from 0. The lappet movable section 50 in the above configuration has the center of the pipe 42 as a swing fulcrum. In the lappet having such a configuration, it is inevitable that cotton lint or the like adheres to the gap between the annular portion 50a of the lappet movable portion 50 and the outer peripheral surface of the pipe 42, so that periodic cleaning is required.

FIG. 21 shows a lappet having such a structure.
Is a plastic lappet supporting portion 52 fixed to a pipe 42 for attaching the lappet.
And a support shaft 53 provided above the lappet support portion 52.
And a lappet movable portion 54 that swings in the direction of arrow C via the. In other words, since the swinging mechanism is configured to swing without using the outer peripheral surface of the pipe 42, there is no possibility that cotton dust adheres to the swinging portion. Note that the lappet movable portion 54 is provided with a front upper edge 52a and a rear upper edge 52b of the lappet support portion 52.
The swing range is restricted by contact with the lappet, and the lappet support portion 52 is
The lappet supporting portion 52 is fixed to the pipe 42 by tightening the slit 52c in a direction to reduce the width of the slit 52c using a bolt and a nut (not shown).

[0008]

Problems to be Solved by the Invention
The lappet 41 described in Japanese Patent Publication No. 80 and shown in FIG.
Is freely detached from the lappet main body 43 or the lappet support portion 52. Therefore, when assembling the lappet 41 to the round pipe 42, it is necessary to pass the regulating ring 44 through the round pipe 42 in a state where the holes are held between the pair of ring portions 43a of the lappet body 43 so that the operation is troublesome. Becomes In a general ring spinning machine, the number of weights disposed on one side of the frame is 200 to 250 weights, and in the case of a large number of weights, the weight is 400 to 500 weights. Will also be higher. In addition, since the restricting ring 44 is freely detached from the lappet main body 43, there is a problem that one of the restricting rings 44 is lost at the time of storage and the handling is complicated.

On the other hand, a lappet 51 having the structure shown in FIG.
In this case, since the tightening force on the pipe 42 is weak, loosening may occur during operation. In addition, the lappet support 52
However, the structure provided with the slit 52c complicates the shape of the lappet, and the thickness of the member must be increased in order to secure sufficient strength as the lappet. is there.

The present invention has been made in view of the above problems, and has as its object the advantage of using a round pipe or a round rod instead of a wrappet angle.
In addition, it is an object of the present invention to provide a lappet for a spinning machine that can easily assemble the lappet to a support, can operate stably in a compact shape, and can reduce the manufacturing cost.

[0011]

In order to achieve the above object, according to the first aspect of the present invention, it is fixed so as to be integrally rotatable with respect to a rod-shaped support provided in parallel with a spindle rail. A support bracket, and a lappet body swingably supported by the support bracket so that the support bracket can be disposed at a spinning position and a retracted position when the support bracket is fixed to the support. In the spinning wrappet, the support bracket includes a through hole for inserting the support into a block, and a fastener for fastening and fixing the support bracket to the support in a state where the support is inserted into the support bracket. A screw hole to be combined is formed in a direction orthogonal to the through hole.

[0012] According to the second aspect of the present invention, a support bracket fixed to the rod-shaped support provided in parallel with the spindle rail so as to be integrally rotatable, and the support bracket is fixed to the support. In a spinning lappet comprising a lappet body swingably supported by the support bracket so that the lappet body can be disposed at a spinning position and a retreat position in a retracted state, the support bracket is formed in a U-shape. Each of the opposed plate portions has a through hole for inserting the support, and a plate portion connecting the respective plate portions has a hole through which a fastener is inserted. Having
A nut is arranged in a non-rotatable state in a gap between the flat plate portion and the outer peripheral surface of the support inserted into the through-hole, and a fastener is screwed to the nut and tightened, thereby fixing the support bracket. It was configured to be fixed to the support.

According to a third aspect of the present invention, in the second aspect of the present invention, the flat plate portion and the outer peripheral surface of the support are connected to the flat plate portion in a state where the support bracket is fitted into the support. A positioning projection is formed which can engage with the nut arranged in the gap and hold the nut at a position corresponding to the hole.

According to a fourth aspect of the present invention, in the first aspect of the present invention, the lappet main body is disposed at a retracted position on a rear upper portion of the support bracket. The engagement surface which engages with the lappet body is formed as a plane extending obliquely rearward and downward.

According to the first to fourth aspects of the present invention, the support bracket constituting the lappet is used in a state of being integrally rotatably fixed to a rod-shaped support provided in parallel with the spindle rail. Is done. The wrappet body can swing between a spinning position and a retreat position where it does not hinder the operator from pulling out the bobbin from the spindle when the yarn breaks.
Also, since the lappet body is swingably supported by the support bracket, when assembling the lappet to the support,
There is no need to support the lappet body, and when the support bracket is fixed to the support with fasteners, the lappet body is also automatically assembled at a predetermined position.

According to the second aspect of the present invention, since the support bracket is formed of a metal plate member, it can be easily manufactured by press working. According to the third aspect of the present invention, the nut used when fixing the support bracket to the support is:
When placed in the gap between the U-shaped metal plate member and the support,
It is arranged at a predetermined position suitable for screwing of the fastener by engaging with the positioning projection.

According to the fourth aspect of the present invention, when the lappet body is rotated to the retreat position at the time of splicing, the position where the lappet body is engaged with the engaging surface is the retreat position. Since the engagement surface is formed as a plane extending obliquely rearward and downward, fly waste is unlikely to accumulate. Further, the processing is simplified.

BEST MODE FOR CARRYING OUT THE INVENTION

(First Embodiment) Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 4, a support arm 2 is fixed to an upper end of a pillar 1 that is raised and lowered by a lifting mechanism (not shown), and a ring rail 3 is fixed to an upper surface of the support arm 2. A ring 5 for guiding the traveler 4 is fixed to a fitting hole formed at a predetermined pitch in the ring rail 3. The rear portion of the ring rail 3 is bent upward at a right angle to form a mounting portion 3a. A balloon control ring 6 is fixed to the mounting portion 3a by a screw 9 so as to correspond to each spindle 8 supported on a spindle rail 7. The balloon control ring 6 has a support portion 6a extending substantially horizontally, and the support portion 6a is fixed to a mounting piece 10 fixed to the mounting portion 3a by a screw 9.

Above the balloon control ring 6, the yarn Y sent from a draft part (not shown)
A lappet 12 provided with a snell wire 11 for guiding the pallet is provided so as to be able to move up and down. The lappet 12 is a rod-shaped pivotally supported via a bracket 13a so as to extend in parallel with the spindle rail 7 with respect to a pillar 13 which is raised and lowered independently and synchronously with the pillar 1 supporting the ring rail 3. Attached to the support 14. In this embodiment, a rod in which a flat portion 14a is formed on a part of a round rod is used as the support 14. Support 1
Numeral 4 is arranged such that the plane portion 14a extends in the vertical direction in the spinning state.

The lappet 12 includes a support bracket 15 fixed so as to be able to rotate integrally with the support 14 and a lappet main body 16 provided with the snell wire 11. The support bracket 15 is formed by casting into a substantially square pillar-shaped block in which a fitting hole 17 is formed as a through hole for fitting a support having a shape corresponding to the cross section of the support 14. The fitting hole 17 is formed such that a positioning surface 17a corresponding to the flat portion 14a of the support 14 extends in the up-down direction. A screw hole 18 is formed in the support bracket 15 on the side facing the positioning surface 17a, and is fixed to the support 14 via a screw 19 as a fastener screwed into the screw hole 18. For example, a hexagon socket set screw is used as the screw 19.

The lappet body 16 is formed by sheet metal working, and is formed in a substantially inverted U-shape in front so as to cover both upper portions of the support bracket 15, as shown in FIG. The base end of the U-shaped bent snell wire 11 is fixed to the front lower surface of the wrappet body 16 via a nut 20 and a screw 21. Snell wire 11 is nut 20
By loosening the tightening between the screw and the screw 21, it can be stored or fed in the direction of arrow P in FIG. As shown in FIG. 2, the snell wire 11 is formed at the front end of the lappet main body 16 so as to be bent downward and formed into a restricting portion 1.
By engaging with 6a, the base end can be positioned so as to extend in a direction perpendicular to the rotation axis of the lappet 12.

The lappet body 16 is swingably supported by a support bracket 15 via a support shaft 22 disposed on the upper rear side thereof. The support shaft 22 may be a pipe. As shown in FIGS. 1 and 3 (b), an engaging portion 15a protrudes from an upper front end of the support bracket 15, and an engaging surface 15b is formed on a rear upper portion as a plane extending obliquely rearward and downward. Is formed. The lappet body 16 is held at a spinning position that extends substantially horizontally with only a substantially central portion of the lower surface being engaged with the engaging portion 15a, and is moved rearward while the rear lower surface is engaged with the engaging surface 15b. The rotation is restricted and the device is arranged at the retracted position.

Next, the operation of the lappet constructed as described above will be described. The support body 14 is rotatable about the pillar 13, and at the time of spinning, the plane portion 14 a is supported in a state of extending vertically, and is integrally moved up and down together with the pillar 13. During spinning, the lappet body 16 rotatably attached to the support bracket 15 is held by its own weight at a spinning position where the lower surface abuts the engaging portion 15a of the support bracket 15 and extends horizontally. Then, the yarn Y sent out from the draft part is wound around the bobbin B via the snell wire 11 and the traveler 4.

When a thread break occurs, the operator needs to pull out the bobbin B of the thread break weight from the spindle 8 to perform a splicing operation. When the lappet body 16 is at the spinning position, the snell wire 11 becomes an obstacle when pulling out the bobbin B. The operator pulls out the bobbin B in a state where the lappet body 16 is rotated to the retracted position by applying a force for moving the lappet body 16 upward. When the lappet body 16 is rotated upward about the support shaft 22, that is, clockwise in FIGS. 1 and 4, the lower surface thereof is engaged with the engagement surface 15 b when rotated to the retracted position. Movement is regulated. When the operator releases his / her hand, it returns to the spinning position by its own weight. Further, at the time of doffing, the support 14 is rotated clockwise in FIGS.
Is rotated integrally with the support 14 via the support bracket 15, and the lappet 12 of the entire weight is disposed at the retracted position.
When the doffing is completed, the support 14 is rotated in the opposite direction,
The lappet 12 of all weights returns to the spinning position.

The assembly of the lappet 12 on the support 14
This is performed before assembling the support 14 to the pillar 13. When mounting the lappet 12 on the support 14, the support 14 is inserted through the fitting hole 17 with the positioning surface 17a corresponding to the flat portion 14a, and the support bracket 15 is moved along the support 14 to a predetermined position. . After moving to a predetermined position, the screw 19 is tightened to
Is fixed to the support 14 and the lappet 12 is assembled at a predetermined position of the support 14. After the predetermined number of lappets 12 have been assembled, both ends of the support 14 are assembled to the pillars 13 via the brackets 13a.
At this time, it is assembled so that the plane portion 14a is vertical in the spinning state.

This embodiment has the following effects. (A) Since the support 14 has substantially the same second moment of area as the round rod, the advantage of using a round pipe or a round rod instead of the wrappet angle, that is, supporting the support 14 without enlarging it. The torsion of the body 14 can be reduced, and the lappet 12 of all weights can be arranged at a predetermined retracted position when doffing.

(B) Since the lappet body 16 is swingably supported by the support bracket 15 via the support shaft 22, the lappet body 16 is supported when the lappet 12 is assembled to the support 14. Without support bracket 1
The wrappet 12 can be assembled simply by assembling the support 5 with the support 5, and the operation is simplified. Further, since there is no possibility that the support bracket 15 and the lappet body 16 are separated, storage and handling are simplified.

(C) Since the center of rotation of the lappet body 16 when swinging with respect to the support bracket 15 is set to be behind the center of rotation of the support 14, the bobbin B The angle at which the lappet body 16 is rotated to a position where it does not hinder the pulling of the puppet from the spindle 8 is reduced. In addition, the center of gravity of the lappet body 16 is located before the center of relative rotation with respect to the support bracket 15,
The lappet body 16 disposed at the retracted position returns to the spinning position by its own weight in a free state.

(D) Since the engagement surface 15b for positioning the retracted position of the lappet body 16 is formed as a plane extending obliquely rearward and downward on the upper rear side of the support bracket 15, fly waste is accumulated. And the engagement surface 15
Processing of b becomes easy.

(E) Since the support bracket 15 is made of metal, the strength is increased with a smaller wall thickness as compared with the case where it is made of plastic, and the tightening force of the screw 19 can be increased. (F) Since the support bracket 15 has a structure in which the insertion hole 17 and the screw hole 18 are provided in the metal block, the structure is simple and the manufacture is easy.

(G) Since the support bracket 15 is formed into a block shape by casting instead of sheet metal processing and is provided with the screw hole 18, the support bracket 15 is
When fixing the wrappet 12 to the support 14, no nut is required, and the assembling work of the lappet 12 on the support 14 is simplified.

(H) Since the fixing screw 19 is attached from the front side of the support bracket 15, it becomes easy to work while the head of the screw 19 is visible when tightening or loosening the screw 19, and the screwdriver is attached to the screw 19. The fitting is easy, and the assembling work of the lappet 12 is easy.

(4) Since the positioning of the spinning position of the lappet body 16 is performed by the lower surface of the lappet body 16 abutting on the engaging portion 15a formed on the upper portion of the support bracket 15, Compared to a configuration that abuts the whole, processing accuracy of the upper surface is not so required,
Manufacturing is simplified.

(G) A positioning surface 17a is formed in a fitting hole 17 formed in the support bracket 15 so as to abut on a flat portion 14a formed on the support 14. Therefore, the lappet 12 is positioned with respect to the support 14 so that the lappet main body 16 extends in a predetermined direction in a state where the support bracket 15 is fitted to the support 14, and a so-called leveling operation for each lappet 12 is performed. Becomes unnecessary. Also,
When assembling the support 14 to the pillar 13, the flat portion 14a
Serves as a reference plane.

(Second Embodiment) Next, a second embodiment will be described with reference to FIGS. FIG.

It has a metal lappet movable part 25 as a lappet main body that is attached so as to straddle the member 24 and swings in the direction of arrow A. The lappet movable portion 25 maintains its horizontal posture by contacting a chamfered portion 23a formed on the support shaft 23, and has a maximum deflection angle by contacting a horizontal surface 24a formed on an upper portion of the lappet support member 24. (Swing range) is regulated.

Hereinafter, the configuration of each section will be described in detail. The configuration of the distal end side of the lappet movable section 25 described above is basically the same as that of the first embodiment, and the snell wire 11 is attached to the distal end side. Note that the lappet movable portion 25 has a regulating portion 25a that engages with the snell wire 11.

On the other hand, as shown in FIG. 7, a pair of leg portions 25b (only the near side is shown) extending downward and parallel is formed on the rear end side of the lappet movable portion 25, as shown in FIG. 25b, the chamfered portion 2 of the support shaft 23
Restriction surfaces 25c for holding the lappet movable portion 25 in horizontal contact with the surface 3a are formed.

The wrappet support member 24 is
A pair of annular portions 24c as a plate portion having a fitting insertion hole 24b as a through-hole to be inserted into the annular portion 24d, and a flat plate portion 24d connecting the annular portions 24c to each other. The flat plate portion 24d is integrally formed in a U-shape by pressing a metal plate (for example, a steel plate).
The annular portion 24c is provided with a chamfered portion 24e corresponding to the chamfered portion 23a described above, and the approximate positioning (cross-sectional direction of the support shaft 23) is performed simply by inserting the lappet support member 24 into the support shaft 23. At).

The flat plate portion 24d has a hole 24f as a hole for inserting the screw 19 toward the center of the support shaft 23.

A commercially available JIS hexagonal nut (for example, JIS B
M6 nut 26 defined in 1181 is disposed,
The hex nut 26 has a hex socket set screw (for example, JI
A screw 19 made of an M6 screw specified in SB 1177) is screwed into the screw 19, and the head of the screw 19 is substantially the same height as the peripheral edge of the hole 24f when the tightening is completed. Therefore, if the screw 19 is tightened using a hexagon wrench, the lappet support member 24 can be fixed to the support shaft 23. The hexagonal nut 26 is selected to have a size that does not rotate when placed in the U-shaped wrappet support member 24.

The lappet movable section 25 is swingably supported by a lappet support member 24 using a support shaft (pin) 22. The lappet movable section 25 is held on the support shaft 22 in a horizontal posture. A coil spring 27 that urges the coil spring 27 is wound. FIG. 8 shows the arrangement of the lappet movable section 25 and the lappet support member 24 when the coil spring 27 is wound. When the diameter d of the support shaft 23 is 20 mm, L1 in FIG. 8 is 11 mm and L2 is 16 mm.

(Third Embodiment) Next, a third embodiment will be described with reference to FIGS. The same parts as those in the above embodiments are denoted by the same reference numerals, and detailed description is omitted.

In the lappet 12 shown in FIG. 9, the swing fulcrum of the lappet movable portion 28 is disposed above the support shaft 23 and behind the vertical center axis CL. The lappet support member 29 is formed of a U-shaped plate member similarly to the second embodiment, and a horizontal surface 29a (only the near side is shown) having the same height is formed on an upper portion thereof. A pin hole for inserting the support shaft (pin) 22 is provided at the rear end. Further, a recess 29 is provided below the pin hole.

It is regulated by contact with

In this configuration, when the lappet movable portion 28 is in the horizontal position, the lappet support member 29 can be covered, so that falling cotton chips and the like can be prevented from entering the lappet support member 29. . Note that the horizontal posture of the lappet movable section 28 is maintained by the top plate inner surface 28a of the lappet movable section 28 being supported by both horizontal surfaces 29a.

FIG. 11 shows that the coil spring 27 is attached to the support shaft 22.
This shows a state in which the coil spring 2 is wound.

The present invention is not limited to the above embodiments, but may be embodied as follows, for example. (1) In the first embodiment, FIG.
As shown in (b), the shape of the insertion hole 17 is circular, and a round rod having no flat portion 14 a is used as the support 14. When a round rod or a round pipe is used as the support 14, the support bracket 15 is attached to the support 1.
It is not possible to automatically position the support bracket 15 with respect to the support 14 simply by inserting it into the support 4. However, as shown in FIGS. 12A and 12B, the support bracket 15 has a horizontal surface below the support bracket 15, and the support bracket 15 is in a state before being fixed to the support 14 via the screw 19. Since each lappet 12 is supported so as to be relatively rotatable with respect to the support body 14, the positioning of each lappet 12 becomes easy.
For example, a support 14 into which a predetermined number of lappets 12 are inserted.
Is placed on the support table with the lower surface of each support bracket 15 facing the horizontal surface of the support table with the screws 19 loosened, and the vibration is applied to the lower surface of each support bracket 15 so that It is positioned in contact. Screw 19 in that state
Is tightened, there is no need to level out each lappet 12.

As shown in FIGS. 2A and 2B, a configuration in which the lower surface of the lappet body 16 abuts on the upper surface of the support bracket 15 and is held at the spinning position without forming the engaging portion 15a on the support bracket 15. And In this case, the distance from the center of the support shaft 22 to the upper surface of the rear portion of the support bracket 15 is set to the distance from the center of the support shaft 22 to the lower surface of the lappet body 16 so that the lower surface of the lappet body 16 does not interfere with the upper surface of the support bracket 15. It must be formed below. And FIG.
When the arc surface 15c is formed at the rear end of the support bracket 15 as shown in FIGS. 12A and 12C, it is necessary to separately form the engagement surface 15b, but as shown in FIG. In this case, the inclination can be changed simply by changing the inclination of the engagement surface 15b, thereby simplifying the processing. Also, the arc surface 15
In the case where c is formed, fly waste is caught in the narrow gap and is easily deposited, but in the case of a flat slope, fly waste is difficult to be deposited.

(3) In the first embodiment, the insertion hole 17 is formed in such a shape that the positioning surface 17a is located on the front side as shown in FIG. 13 (a), and downward as shown in FIG. 13 (b). It may be formed in a shape that is positioned or a shape in which the positioning surface 17a is positioned on the upper side or extends obliquely. However, when the support 14 is assembled to the pillar 13 via the bracket 13a so that the flat portion 14a extends in the horizontal direction or the vertical direction, the positioning at the time of assembling the support 14 is simplified. It is preferable to form so as to extend in the up-down direction or the front-back direction.

(4) The mounting position of the screw 19 is not limited to the front side or the lower side of the support bracket 15, but may be any position at the rear side, the upper side, or the position extending obliquely. Further, the mounting position of the screw 19 may be set to an arbitrary position without considering the position of the positioning surface 17a. However, the configuration in which the support 14 is pressed by the screw 19 from the side opposite to the positioning surface 17a as in the above-described embodiment is more preferable.
a reliably contacts the flat portion 14a, so that the positioning effect is large.

(5) In order to prevent the wrappet body 16 from swaying due to vibration, a V-shaped engagement groove 30 is formed in the engagement portion 15a as shown in FIGS. An engagement protrusion 31 is formed at a position facing the engagement groove 30 on the lappet body 16 side. The engagement protrusion 31 is engaged by, for example, press working. In this case, when the lappet main body 16 is disposed at the spinning position, the engagement protrusion 31 is held in a state of being engaged with the engagement groove 30 to prevent the swaying.
