<First embodiment>
A false twisting machine 1 according to a first preferred embodiment of the present invention will be described with reference to FIG. 1. Note that the direction perpendicular to the plane of FIG. 1 is the longitudinal direction of the machine frame, and the left-right direction of the plane of FIG. 1 is the width direction of the machine frame. The direction perpendicular to both the machine longitudinal direction and the machine width direction is the vertical direction (vertical direction) in which gravity acts.

The false twisting machine 1 is configured to be capable of false twisting a yarn Y made of synthetic fibers such as nylon (polyamide fiber) and polyester. The false twisting machine 1 includes a yarn feeding section 2 for supplying yarn Y, a processing section 3 for false twisting the yarn Y supplied from the yarn feeding section 2, and a processing section 3 for false twisting the yarn Y processed by the processing section 3. It includes a winding section 4 that winds the winding around the winding bobbin Bw.

The yarn feeding section 2 has a creel stand 5 that holds a plurality of yarn feeding packages Ps. The yarn feeding section 2 supplies a plurality of yarns Y to the processing section 3. The processing section 3 falsely twists the yarn Y supplied from the yarn supply package Ps. The processing section 3 includes, in order from the upstream side in the yarn running direction, a first feed roller 11a, a twist guide 12, a heating device 13, a cooling device 14, a false twisting device 15, a tension sensor 16, a second feed roller 11b, and an interlacing device. 17, a third feed roller 11c, and an oil supply device 20 are arranged. The winding unit 4 winds the yarn Y that has been false twisted in the processing unit 3 onto a winding bobbin Bw using a winding device 10 to form a winding package Pw.

Further, the false twisting machine 1 includes a main machine stand 18 extending in the longitudinal direction of the machine stand and a support frame 19. A winding device 10 is attached to the main engine stand 18 . The main machine stand 18 is arranged to face the creel stand 5 across the work space A in the machine stand width direction. Each device constituting the processing section 3 is attached to the support frame 19. Each device constituting the processing section 3 is arranged above the work space A.

In the false twisting machine 1, a plurality of processing units (also called weights) each having a yarn path formed so as to pass through each device constituting the processing section 3 are arranged in a line in the longitudinal direction of the machine. As a result, the false twisting machine 1 can simultaneously perform false twisting on the plurality of yarns Y running in a line in the machine machine longitudinal direction.

In this embodiment, the first feed roller 11a, the second feed roller 11b, and the third feed roller 11c are provided in common to a plurality of weights (for example, two weights). Further, the heating device 13 and the cooling device 14 are provided in common to a plurality of weights (for example, four weights). Further, a twisting guide 12, a false twisting device 15, a tension sensor 16, an interlacing device 17, and an oil supply device 20 are provided for each weight.

The yarn Y supplied from the yarn feeding section 2 to the processing section 3 is stretched between the first feed roller 11a and the second feed roller 11b, and twisted by the false twisting device 15. The twist formed by the false twisting device 15 is propagated to the twist stop guide 12, but is not propagated upstream of the twist stop guide 12 in the yarn running direction.

The thread Y thus drawn and twisted is heated by the heating device 13 and then cooled by the cooling device 14 and heat-set. The yarn Y that has passed through the false twisting device 15 is untwisted before reaching the second feed roller 11b. However, since the twist of the yarn Y is heat-set as described above, each filament maintains a wavy false twist state. Note that abnormalities in the yarn Y, such as abnormal tension and yarn breakage, can be detected by the tension sensor 16 disposed between the false twisting device 15 and the second feed roller 11b.

Thereafter, the yarn Y is loosened between the second feed roller 11b and the third feed roller 11c, and entangled by the interlacing device 17. Further, an oil agent is applied to the yarn Y by the oil supply device 20. The thread Y to which the oil has been applied is wound up by the winding device 10 in the winding section 4 . Note that the oil agent is already attached to the yarn Y of the yarn supply package Ps. In the oil supply device 20, the oil agent is additionally applied to the yarn Y to which the oil agent is already attached.

In the false twisting machine 1, the yarn Y travels along a predetermined yarn path from the yarn feeding section 2 to the winding section 4. For example, Japanese Patent Laid-Open No. 2021-127532 discloses an oil application guide (the invention A spinning take-off machine is disclosed which is equipped with a "refueling guide" (corresponding to a "refueling guide"). The position of the oil supply guide in the yarn take-up machine with respect to the yarn traveling direction changes depending on the degree of cooling of the yarn spun from the spinneret. That is, the optimal position of the oil supply guide in the yarn traveling direction changes depending on the type of yarn and the like. In the spinning take-off machine configured as described above, as the position of the oil supply guide changes depending on the type of yarn, etc., the yarn path also changes.

The upstream yarn guide 21 is arranged upstream of each oil supply guide 6 with respect to the yarn running direction. The downstream yarn guide 22 is arranged downstream of each oil supply guide 6 with respect to the yarn running direction. That is, the oil supply guide 6 is located between the upstream yarn guide 21 and the downstream yarn guide 22. Between the upstream yarn guide 21 and the downstream yarn guide 22, the yarn path of the yarn Y is determined by being guided by the upstream yarn guide 21 and the downstream yarn guide 22. It is preferable that the upstream yarn guide 21 and the downstream yarn guide 22 be arranged near the oil supply guide 6 so that the yarn Y is sent to the oil supply guide 6 in a state where the fibers are gathered together. The upstream yarn guide 21 is arranged between the third feed roller 11c and the oil supply guide 6. The downstream yarn guide 22 is arranged between the oil supply guide 6 and the winding section 4.

The portion formed in the second portion 83 in the opening 80 is larger than the outer shape of the covering portion 71 in the holder 7 .

The fixing member 8 is located at a first position (see FIG. 9(a)) where the covering portion 71 of the holder 7 is inserted through a portion formed in a first portion 81 of the opening 80 and a second portion 83 of the opening 80. It can take a second position (see FIG. 9(b)) in which the covering portion 71 of the holder 7 is inserted into the formed portion. The first position is lower than the second position in the vertical direction. When the fixing member 8 is in the second position, it does not come into contact with the wall surface 73a of the holder 7 and the bottom surface 66a of the refueling guide 6. Furthermore, when the fixing member 8 is in the second position, the fixing member 8 is movable in the distraction direction. By moving the fixing member 8 located at the second position downward to the first position, the fitting part 82 is fitted into the second space 65 and the first space 72, and the wall surface 73a of the holder 7 and the oil supply guide 6 are fitted. can be brought into contact with the bottom surface 66a of. That is, the fitting direction of the fitting part 82 into the second space 65 and the first space 72 is the vertical direction (linear direction).

A portion of the opening 80 formed in the first portion 81 extends in the vertical direction. A surface defining the opening 80 in the first portion 81 includes a flat surface 81a extending in the vertical direction. As shown in FIG. 8, this plane 81a is the entire surface of the bottom surface 66a of each groove 66 arranged on the same plane when the two fitting parts 82 are fitted into the second space 65 and the first space 72. and two wall surfaces 73a of each through hole 73.

When the two fitting portions 82 are not fitted into the second space 65 and the first space 72, the width of the vertically extending portion formed in the first portion 81 of the opening 80 is such that the lower end thereof is equal to the upper end thereof. It's a little narrower than that. By fitting the two fitting parts 82 into the second space 65 and the first space 72, the portion of the opening 80 formed in the first portion 81 is pushed out to both sides in the arrangement direction. Thereby, the two fitting parts 82 are fitted into the second space 65 and the first space 72, so that the fixing member 8 can sandwich the covering part 71 from both sides in the arrangement direction by elastic force.

When the two fitting parts 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the fixing member 8 is fixed in position in the circumferential direction by the wall surface 73a of the first space 72 formed in the holder 7. is fixed. That is, the wall surface 73a corresponds to the "first contact surface" of the present invention.

Specifically, in FIG. 8, the movement of the fixing member 8 to one side (clockwise) in the circumferential direction is caused by moving the fixing member 8 to one side in the circumferential direction (clockwise direction) by moving the lower wall surface 73a of the two wall surfaces 73a of the first space 72 on the right side and the first wall surface 73a on the left side. It is regulated by the upper wall surface 73a of the two wall surfaces 73a of one space 72. Further, the movement of the fixing member 8 to the other side in the circumferential direction (counterclockwise side) is performed by moving the fixing member 8 to the upper wall surface 73a of the two wall surfaces 73a of the first space 72 on the right side and the two wall surfaces 73a of the first space 72 on the left side. It is regulated by the lower wall surface 73a of the wall surfaces 73a. Thereby, the position of the fixing member 8 in the circumferential direction is fixed.

The bottom surface 66a of the second space 65 formed in the refueling guide 6 contacts the two fitting parts 82 of the fixing member 8 whose position in the circumferential direction is fixed, thereby changing the position of the refueling guide 6 in the circumferential direction. to be fixed. That is, the bottom surface 66a corresponds to the "second contact surface" of the present invention. Further, the bottom surface 66a corresponds to the "flow path side contact surface" of the present invention.

Specifically, as shown in FIG. 8, the movement of the refueling guide 6 to one side in the circumferential direction (the direction of the arrow indicated by D1 in the figure: clockwise side) is performed by moving the refueling guide 6 along the plane 81a of the right fitting portion 82. is in contact with the upper part of the bottom surface 66a of the second space 65 on the right side, and the flat surface 81a of the left fitting part 82 is in contact with the lower part of the bottom surface 66a of the second space 65 on the left side. be done. The upper portion of the bottom surface 66a of the second space 65 on the right and the lower portion of the bottom surface 66a of the second space 65 on the left both face one side in the circumferential direction.

Furthermore, when the refueling guide 6 is moved to the other side in the circumferential direction (the direction of the arrow indicated by D2 in the figure: counterclockwise side), the flat surface 81a of the right fitting part 82 is in the second space 65 on the right. It is regulated by contacting the lower part of the bottom surface 66a, and the flat surface 81a of the left fitting part 82 contacting the upper part of the bottom surface 66a of the left second space 65. The lower part of the bottom surface 66a of the second space 65 on the right and the upper part of the bottom surface 66a of the second space 65 on the left both face the other side in the circumferential direction. Thereby, the position of the refueling guide 6 in the circumferential direction is fixed.

Furthermore, when the two fitting portions 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the fixing member 8 fits between the bottom surface 66a of the second space 65 and the wall surface 73a of the first space 72. , the movement on both sides of the arrangement direction is restricted. That is, movement of the fixing member 8 to one side in the arrangement direction (right side in FIG. 8) is regulated by the bottom surface 66a of the second space 65 on the left side in FIG. 8 and the two wall surfaces 73a of the first space 72. be done. Movement of the fixing member 8 to the other side in the arrangement direction (left side in FIG. 8) is regulated by the bottom surface 66a of the second space 65 on the right side in FIG. 8 and the two wall surfaces 73a of the first space 72. .

Here, the length of the second space 65 of the refueling guide 6 in the extension direction (the distance between the two wall surfaces 66b) is L1 (see FIG. 5(b)), and the length of the first space 72 of the holder 7 in the extension direction (The distance between the two wall surfaces 73b) is L2 (see FIG. 6(b)), and the length of the fitting portion 82 in the extension direction (thickness of the fixing member 8) is L3 (see FIG. 4). At this time, the lengths L1, L2 and L3 are substantially the same. More specifically, the length L1 of the second space 65 and the length L2 of the first space 72 are such that the fitting portion 82 fits snugly into the second space 65 and the first space 72 in the extension direction. It has become. Both end surfaces in the extension direction of the fitting portion 82 fitted into the second space 65 and the first space 72 contact the wall surface 66b of the second space 65 and the wall surface 73b of the first space 72. That is, the fitting portion 82 is sandwiched between the two wall surfaces 66b of the second space 65 and between the two wall surfaces 73b of the first space 72 from both sides in the extension direction.

As shown in FIG. 5(b), two protrusions 67 are provided at one end of the flow path portion 63 of the oil supply guide 6 in the extension direction. One of the two protrusions 67 is provided on the upper part of the flow path section 63 and protrudes upward from the outer peripheral surface of the flow path section 63. The other of the two protrusions 67 is provided at the lower part of the flow path section 63 and protrudes downward from the outer peripheral surface of the flow path section 63.

As shown in FIG. 6A, two notches 74 are provided at one end of the covering portion 71 of the holder 7 in the extension direction. The two notches 74 form a recessed portion at the edge of the covering portion 71 in the extension direction. That is, the notch 74 corresponds to a "recess" in the present invention. One of the two notches 74 is provided in the upper part of the covering part 71. The other of the two notches 74 is provided at the lower part of the covering portion 71. Two protrusions 67 provided on the refueling guide 6 are fitted into the two notches 74 provided on the holder 7, respectively.

As shown in FIG. 4, an annular packing 9 is arranged between the oil supply guide 6 and the holder 7. The packing 9 seals between the oil supply guide 6 and the holder 7 over the entire circumference. The packing 9 is made of an elastic material such as rubber. The packing 9 is arranged between the first space 72 and a connection end 79a connected to the other end (right side in FIG. 4) of the oil agent flow path 64 in the connection flow path 79 in the extension direction. A groove 76 is provided on the inner surface of the covering portion 71 in the holder 7 and is formed around the entire circumference of the covering portion 71 . The groove 76 is provided between the first space 72 and a connecting surface 78 a in the connecting portion 78 where the connecting end 79 a of the connecting channel 79 opens. The packing 9 is arranged in the groove 76.

(Characteristics of the first embodiment)
As described above, in the false twisting machine 1 of the present embodiment, the oil supply device 20 connects the holder 7 attached to the support frame 19, the discharge port 61a for discharging the lubricant, and the discharge port 61a in the direction orthogonal to the yarn running direction. It has a pair of thread guide members 68 that are arranged on both sides of the outlet 61a and guide the thread Y, and a refueling guide 6 that is detachable from the holder 7. A fixing member 8 fixed to the oil supply guide 6 , a packing 9 disposed between the oil supply guide 6 and the holder 7 , and a packing 9 disposed between the holder 7 and the oil supply guide 6 are provided. The oil supply guide 6 has a cylindrical flow path portion 63 in which a lubricant flow path 64 is formed. The holder 7 has a cylindrical covering portion 71 that is arranged coaxially with the flow path portion 63 and can cover the outer circumferential surface of the flow path portion 63 . Further, the holder 7 is provided with a wall surface 73a that can come into contact with the fixing member 8, and the refueling guide 6 is provided with a bottom surface 66a that can come into contact with the fixing member 8. The wall surface 73a is a surface that fixes the position of the fixing member 8 in the circumferential direction of the flow path section 63 by coming into contact with the fixing member 8. The bottom surface 66a fixes the position of the refueling guide 6 in the circumferential direction by coming into contact with the fixing member 8 whose position in the circumferential direction is fixed by the wall surface 73a.

According to the above configuration, by inserting the flow path portion 63 into the covering portion 71 and covering the outer circumferential surface of the flow path portion 63 with the covering portion 71, the surface perpendicular to the extension direction of the flow path portion 63 (that is, the upper and lower The position of the refueling guide 6 within a plane parallel to both the direction and the arrangement direction can be fixed. Therefore, by covering the outer circumferential surface of the flow path section 63 with the covering section 71, it is possible to ensure the reproducibility of the position of the oil supply guide 6 with respect to the yarn path. Further, by bringing the fixing member 8 into contact with the wall surface 73a of the holder 7 and the bottom surface 66a of the refueling guide 6, the position of the refueling guide 6 in the circumferential direction can be fixed, and the reproducibility of the posture of the refueling guide 6 can be ensured. In addition, by covering the outer peripheral surface of the flow path section 63 with the coating section 71 and bringing the fixing member 8 into contact with the wall surface 73a of the holder 7 and the bottom surface 66a of the refueling guide 6, the refueling guide 6 can be easily fixed. can.

Furthermore, in the false twisting machine 1 of this embodiment, a notch 74 that is recessed in the extension direction is formed in the holder 7, and a protrusion 67 that can be fitted into the notch 74 is provided in the oil supply guide 6. Therefore, by fitting the protrusion 67 of the oil supply guide 6 into the notch 74 of the holder 7, alignment of the oil supply guide 6 and the holder 7 in the circumferential direction can be assisted.

In addition, in the false twisting machine 1 of this embodiment, the bottom surface 66a, which is the contact surface with the fixing member 8 in the oil supply guide 6, is connected to the oil agent flow path with the oil agent flow path 64 in between in the arrangement direction perpendicular to the extension direction. 64, respectively. From the viewpoint of improving the accuracy of the reproducibility of the posture of the refueling guide 6, it is preferable to ensure a large contact surface (surface corresponding to the "second contact surface" of the present invention) with the fixing member 8 in the refueling guide 6. If the refueling guide 6 is processed to form a contact surface with the fixing member 8, sharp corners or thin parts may be created in the refueling guide 6, resulting in damage to the refueling guide 6 or machining errors. There is a risk of oil leakage. In particular, since the oil supply guide 6 of this embodiment is made of ceramics, there is a high possibility of damage. Therefore, high precision machining is required. In the fixing structure of this embodiment, a large bottom surface 66a, which is a contact surface with the fixing member 8, can be ensured through easy machining, and the accuracy of reproducibility of the posture of the refueling guide 6 can be improved.

Furthermore, in the false twisting machine 1 of the present embodiment, the bottom surface 66a of the oil supply guide 6 and the wall surface 73a of the holder 7 can be arranged on the same plane, and the fixing member 8 is arranged on the oil supply guide arranged on the same plane. It has a flat surface 81a that contacts the bottom surface 66a of the holder 6 and the wall surface 73a of the holder 7. Therefore, the shape of the fixing member 8 can be simplified.

In addition, in the false twisting machine 1 of the present embodiment, the length L1 of the second space 65 in the extension direction (the distance between the two wall surfaces 66b) and the length L1 of the first space 72 in the extension direction (the distance between the two wall surfaces 73b) The distance L2 is substantially the same as the length L3 of the fitting portion 82 in the extension direction. Therefore, the fitting portion 82 fitted into the second space 65 and the first space 72 is sandwiched by the wall surface 66b of the refueling guide 6 from both sides in the extension direction, and is also sandwiched by the wall surface 73b of the holder 7 from both sides in the extension direction. It will be done. This determines the positions of the refueling guide 6 and the holder 7 in the extension direction.

Furthermore, in the false twisting machine 1 of this embodiment, a groove 76 in which the packing 9 is disposed is formed on the inner surface of the covering portion 71 of the holder 7. Therefore, when the refueling guide 6 is moved relative to the holder 7, the packing 9 is difficult to move.

Furthermore, in the false twisting machine 1 of the present embodiment, the wall surface 73a formed on the holder 7 and the bottom surface 66a formed on the oil supply guide 6 are on both sides of the central axis O of the covering portion 71 in the arrangement direction perpendicular to the stretching direction. are placed in each. The fixing member 8 is made of a material with elastic force, and by coming into contact with the wall surface 73a and the bottom surface 66a arranged on both sides of the central axis O with respect to the arrangement direction, the fixing member 8 moves the flow path portion 63 in the arrangement direction with the elastic force. Pinch from both sides. Therefore, the fixing member 8 is difficult to move, and the positions of the refueling guide 6 and the holder 7 can be stably fixed.

Furthermore, in the false twisting machine 1 of the present embodiment, the fixing member 8 has a first portion 81 formed with a fitting portion 82 that contacts the wall surface 73a of the holder 7 and the bottom surface 66a of the oil supply guide 6; 81 and a second portion 83 adjacent to the second portion 81, and an opening 80 spanning the first portion 81 and the second portion 83 is formed. The portion formed in the second portion 83 in the opening 80 is larger than the outer shape of the covering portion 71 in the holder 7 . The fixing member 8 has a first position where the covering part 71 of the holder 7 is inserted into a part formed in the first part 81 of the opening 80 and the fitting part 82 contacts the wall surface 73a and the bottom surface 66a, and a first position where the fitting part 82 contacts the wall surface 73a and the bottom surface 66a. The covering portion 71 of the holder 7 is inserted through the portion formed in the second portion 83 and can take a second position where it does not come into contact with the wall surface 73a and the bottom surface 66a. Therefore, by setting the fixing member 8 in the first position, the refueling guide 6 and the holder 7 can be fixed, and by setting the fixing member 8 in the second position, the fixing between the refueling guide 6 and the holder 7 can be released. . Since the covering portion 71 of the holder 7 remains inserted into the opening 80 of the fixing member 8 even when the fixation between the refueling guide 6 and the holder 7 is released, loss of the fixing member 8 can be avoided.

Furthermore, in the false twisting machine 1 of this embodiment, the first position of the fixing member 8 is lower than the second position in the vertical direction. Therefore, the fixing member 8 is located at the first position where the refueling guide 6 and the holder 7 are fixed by gravity unless lifted by applying force from the outside. Therefore, it is possible to prevent the fixing member 8 from unintentionally moving from the first position to the second position and releasing the fixation between the refueling guide 6 and the holder 7.

In addition, in the false twisting machine 1 of this embodiment, the wall surface 73a corresponding to the first contact surface and the bottom surface 66a corresponding to the second contact surface are flat. Therefore, processing of the holder 7 and the oil supply guide 6 is easier than, for example, when the fitting portion 82 is a screw and the first contact surface and the second contact surface are surfaces defining a thread groove.

Further, in the false twisting machine 1 of this embodiment, the oil supply guide 6 is made of ceramics. For example, when the fitting part 82 is a screw and the oil supply guide 6 is made of ceramics, when the fitting part 82 of the fixing member 8 is fitted into the second space 65 of the oil supply guide 6 to fix the position of the oil supply guide 6, There is a risk that the refueling guide 6 may break. In this embodiment, even if the oil supply guide 6 is made of ceramics, it is possible to suppress the oil supply guide 6 from cracking.

Furthermore, in the false twisting machine 1 of this embodiment, an annular packing 9 is arranged between the oil supply guide 6 and the holder 7. Therefore, one packing 9 can seal between the oil supply guide 6 and the holder 7 over the entire circumference. Therefore, processing of the packing 9 is easy.

Furthermore, in the false twisting machine 1, since the oil agent is additionally applied to the yarn Y to which the oil agent has already been attached, the required amount of the oil agent to be applied to the yarn Y is small. The oil supply guide 6 can suppress the amount of oil applied to the yarn Y to a relatively small amount. Therefore, it is preferable to apply the oil supply device 20 having the oil supply guide 6 to the false twisting machine 1. According to this embodiment, when the oil supply device 20 having the oil supply guide 6 is applied to the false twisting machine 1, it is possible to easily ensure reproducibility of the position and orientation of the oil supply guide 6 with respect to the yarn path.

In addition, the false twisting machine 1 of this embodiment includes an upstream yarn guide 21 and a downstream yarn guide 22 that are spaced apart in the yarn running direction in which the yarn Y runs. The holder 7 is located between the upstream yarn guide 21 and the downstream yarn guide 22. Therefore, the reproducibility of the position of the refueling guide 6 and the reproducibility of the posture of the refueling guide 6 with respect to the yarn path of the yarn Y guided by the two yarn regulating guides is ensured, and the refueling guide 6 can be easily fixed.

<Second embodiment>

Each fitting portion 82 is fitted across the second space 65 and the two first spaces 72 located above and below the second space 65, respectively. Two wall surfaces 73a facing each other in the arrangement direction in one first space 72 contact both end surfaces in the arrangement direction of the fitting portions 82 fitted into the first space 72.

When the two fitting parts 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, the fixing member 8 is fixed in position in the circumferential direction by the wall surface 73a of the first space 72 formed in the holder 7. is fixed. At this time, the portion of the fitting portion 82 that is fitted into each first space 72 is sandwiched between the two wall surfaces 73a of each first space 72 from both sides in the circumferential direction. That is, the wall surface 73a corresponds to the "first contact surface" of the present invention. The bottom surface 66a of the second space 65 formed in the refueling guide 6 contacts the two fitting parts 82 of the fixing member 8 whose position in the circumferential direction is fixed, thereby changing the position of the refueling guide 6 in the circumferential direction. to be fixed. That is, the bottom surface 66a corresponds to the "second contact surface" of the present invention.

Moreover, when the two fitting parts 82 of the fixing member 8 are fitted into the second space 65 and the first space 72, each fitting part 82 is located on the bottom surface 66a of the second space 65 located on the plane S2. and two wall surfaces 73a of the two first spaces 72, and two wall surfaces 73a of the two first spaces 72, both of which are located on the plane S3, in the arrangement direction. As a result, movement of the fixing member 8 on both sides of the arrangement direction is restricted.

In addition, in this embodiment, the two fitting parts 82 provided in the fixing member 8 may be separate bodies. That is, the fixing member 8 may be divided into two parts, and each fixing member 8 may be provided with the fitting part 82. As described above, each fitting part 82 is connected to the bottom surface 66a of the second space 65 located on the plane S2 and the two wall surfaces 73a of the two first spaces 72, and the two first spaces located on the plane S3. It is sandwiched between the two wall surfaces 73a of 72 in the arrangement direction. Therefore, even when the fixing member 8 is divided into two, movement of each fixing member 8 on both sides in the arrangement direction is restricted. In this way, the fixing member 8 may be divided into a plurality of parts, each of which has limited movement on both sides of the arrangement direction.

(Features of the second embodiment)

Further, in this embodiment, the through hole 73 that defines one first space 72 has two wall surfaces 73a that sandwich the fitting portion 82 from both sides in the circumferential direction. Thereby, the position of the fixing member 8 in the circumferential direction is fixed by fitting the fitting portion 82 into one first space 72.

<Third embodiment>
