The attachment holes 101 are formed in a symmetrical manner in the lower part of the back body of the garment 100, and the garment fans 1 are attached to the left and right attachment holes 101, respectively. The battery 2 is attached to the back surface (inner surface) of the front body. For example, the battery 2 is attached to the lower part of the left front body, and the battery 2 and the pair of left and right clothes fans 1 are connected by a single power supply cable 3. The power supply cable 3 extends from the battery 2 in the horizontal direction and reaches the left and right clothes fans 1. The feeding cable 3 is bifurcated in the middle, and an L-shaped male connector 4 (see FIGS. 9 and 10) is provided at each branched end, and the male connector 4 is a fan for clothes. 1 is connected.

  As shown in FIG. 4, the garment fan 1 includes a rotating wing 10, and the wing 10 rotates to ventilate the front and back sides of the garment 100 through the attachment hole 101. Normally, the wing 10 rotates to take in air from the front side of the garment 100 and discharge air to the back side. That is, external air is sent into the gap between the garment 100 and the body to cool the body. The air sent to the back side of the garment 100 is discharged outside, for example, from the cuffs and the neck of the garment 100.

  The wing 10 is integrally attached to the main shaft 12 of the motor 11 and is driven by the motor 11. For convenience of explanation, the direction of the rotation center line of the wing 10 will be referred to as the up-down direction, and the side that is the back side of the garment 100 when attached to the garment 100 will be described as the upper side. 1, 2, 6, and 7, the internal structure of the motor 11 and the like is not shown. The attachment hole 101 of the garment 100 has a round shape, and the garment fan 1 has a circular shape in plan view as shown in FIG. 3 corresponding to the shape of the attachment hole 101, and the center of rotation of the wing 10 on the center line thereof.

In addition, it is preferable that the housing 15 and the holding ring 14 of the main body 13 are both made of synthetic resin for weight reduction.

<Bottom portion 16>
The bottom surface portion 16 may be flat, but has a convex shape that slightly bulges downward as shown in FIGS. 2 and 4. A large number of ventilation holes 20 are formed in the bottom surface portion 16. As the wing 10 rotates, air flows into the housing 15 from the vent hole 20 of the bottom surface portion 16. Accordingly, the vent hole 20 in the bottom surface portion 16 is the intake-side vent hole 20.

<Surrounding wall 18>
The peripheral wall portion 18 is divided into an upper portion 18a and a lower portion 18b. A large number of air holes 20 are formed in the upper portion 18a, while no air holes 20 are formed in the lower portion 18b. The outer peripheral surface of the lower portion 18b of the peripheral wall portion 18 extends with a constant diameter along the vertical direction. The upper portion 18 a of the peripheral wall portion 18 has a smaller diameter than the lower portion 18 b of the peripheral wall portion 18 and is connected to the top surface portion 17 smoothly.

  A male screw portion 21 is formed on the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18. The male screw portion 21 is formed only in the middle portion in the vertical direction on the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18. Accordingly, the male screw portion 21 is located a predetermined distance above the flange portion 19, and the male screw portion 21 is formed below the male screw portion 21 on the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18. There is no smooth surface 22 over the entire circumference. The vertical separation distance between the male screw portion 21 and the holding surface 19 a of the flange portion 19 is greater than the thickness of the garment 100, specifically, the thickness of the fabric of the garment 100 at the opening edge of the attachment hole 101. It is larger than the protrusion height of the pressing projection 23 of the flange portion 19 described later. Furthermore, the vertical separation distance between the male screw portion 21 and the holding surface 19 a of the flange portion 19 is larger than the screw pitch of the male screw portion 21. Similarly, on the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18, a smooth surface on which the male screw portion 21 is not formed also exists above the male screw portion 21. As shown in FIG. 5, the tip of the thread of the male screw portion 21 is rounded in a circular arc shape in cross section, not a sharply pointed shape or an angular shape. Further, as shown in FIG. 6, in the present embodiment, the start point 21 a and the end point 21 b of the male screw part 21 are at substantially the same angular position on the entire outer periphery of the lower part 18 b of the peripheral wall part 18. However, the start point 21a and the end point 21b of the male screw part 21 may be at different angular positions.

<Flange part 19>
The flange portion 19 extends in a direction perpendicular to the axial direction of the peripheral wall portion 18, and thus the flange portion 19 extends in the horizontal direction. The upper surface of the flange portion 19 is a holding surface 19a that comes into contact with the surface of the garment 100, and the holding surface 19a is a surface orthogonal to the vertical direction. The outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18 is orthogonal to the holding surface 19 a of the flange portion 19. For example, the width of the flange portion 19 is substantially constant over the entire circumference. The flange portion 19 is continuous with the peripheral edge portion of the bottom surface portion 16 in the radial direction.

  A pressing protrusion 23 that is pressed against the surface of the garment 100 is formed on the holding surface 19 a of the flange portion 19. Although the shape, arrangement, number, and the like of the pressing protrusions 23 are arbitrary, they are preferably arranged at equal intervals in the circumferential direction as shown in FIGS. 6 and 7, for example, formed at a total of four locations at intervals of 90 degrees. The However, two pressing protrusions 23 may be formed at intervals of 180 degrees or three positions at intervals of 120 degrees. The pressing protrusion 23 is preferably formed over the entire width of the sandwiching surface 19a of the flange portion 19, for example, a shape extending in a streak shape along the radial direction from the inner edge to the outer edge of the sandwiching surface 19a of the flange portion 19. As good as Moreover, it is preferable that the pressing protrusion 23 has a shape in which the upper end is narrower than the lower end.

<Top surface part 17>
The top surface portion 17 has a dome shape that bulges upward as a whole. The top surface portion 17 is substantially flat at the circular top portion 17a, and is gradually lowered from the peripheral portion of the top portion 17a toward the radially outer side and is connected to the peripheral wall portion 18. That is, the top surface portion 17 includes a top portion 17a located at the center portion, and a tapered shoulder portion 17b that is provided annularly on the outer side in the radial direction of the top portion 17a and gradually descends from the top portion 17a to the peripheral wall portion 18. And. A large number of vent holes 24 are formed in the shoulder portion 17 b of the top surface portion 17. The vent hole 24 in the upper portion 18a of the peripheral wall portion 18 and the vent hole 24 in the peripheral portion of the top surface portion 17 have a continuous hole shape. A number of air holes 24 formed in this manner from the shoulder portion 17b of the top surface portion 17 to the upper portion 18a of the peripheral wall portion 18 are exhaust side air holes 24. When the wing 10 is rotated, air is passed through the air holes 24. It is discharged from the inside of the housing 15 through the outside.

  An insertion port 25 is formed in the vicinity of the boundary between the top portion 17 a and the shoulder portion 17 b of the top surface portion 17, and a power receiving connector 26 is disposed inside (inside) the insertion port 25. The power receiving connector 26 is located below the top portion 17 a of the top surface portion 17. The L-shaped male connector 4 of the power feeding cable 3 is connected to the power receiving connector 26 through the insertion port 25, and power is supplied from the power receiving connector 26 to the motor 11. The insertion port 25 is located in the upper part 18a of the housing 15, and is opened toward the outer side in the radial direction. Accordingly, the male connector 4 is connected to the power receiving connector 26 in the radial direction.

  An escape portion 27 for avoiding interference with the male connector 4 is provided around the insertion port 25. The escape portion 27 is formed at a predetermined position in the entire circumference of the shoulder portion 17 b of the top surface portion 17. The escape portion 27 is formed from the shoulder portion 17b of the top surface portion 17 to the upper portion 18a of the peripheral wall portion 18, and is formed as a concave portion that is recessed downward by one step with respect to the left and right sides in the circumferential direction. The escape portion 27 has a fan shape in plan view, and its central angle is, for example, about 40 to 60 degrees. FIG. 13A schematically shows a formation region of the relief portion 27 in plan view. In FIG. 13A, a portion where cross hatching is performed is a region where the escape portion 27 is formed.

  Further, the escape portion 27 has a bilaterally symmetric shape with the insertion port 25 as the center in a front view when the insertion port 25 is viewed from the front as shown in FIG. In a state where the male connector 4 is connected to the power receiving connector 26, the male connector 4 can be rotated around the axis in the connecting direction. In a state where the male connector 4 is connected to the power receiving connector 26, from a state where the male connector 4 is horizontally tilted to the right as shown in FIG. 9 to a state where the male connector 4 is horizontally tilted to the left as shown in FIG. The male connector 4 can be rotated 180 degrees. When the male connector 4 is horizontally tilted to the right as shown in FIG. 9 is set to the 0 degree position, and when the male connector 4 is horizontally tilted to the left as shown in FIG. The connector 4 can be freely rotated in an angle range of 180 degrees from the 0 degree position to the 180 degree position. For example, when the male connector 4 is set to the 0 degree position, a gap S exists between the male connector 4 and the shoulder portion 17b of the housing 15 or the upper portion 18a of the peripheral wall portion 18 as shown in FIG. The male connector 4 does not interfere with the shoulder 17b of the housing 15. The same is true when the male connector 4 is positioned 180 degrees, and the male connector 4 does not interfere with the shoulder portion 17b of the housing 15 or the upper portion 18a of the peripheral wall portion 18.

  In addition, the formation area of the escape part 27 may have various shapes. That is, the formation area of the relief portion 27 is not formed in a fan shape in plan view having a predetermined center angle, but in a radial direction at a position spaced a predetermined distance from the center of the main body 13 in plan view as shown in FIG. It is good also as D cut shape divided by the straight line pulled in the orthogonal direction. In FIG. 13B, the portion where cross hatching is performed is a region where the escape portion 27 is formed.

<Member Configuration of Housing 15>
The housing 15 is composed of a plurality of members. That is, the housing 15 includes a base 30 positioned on the lower side, a mesh-like cover 31 connected to the upper side of the base 30, and a cap 32 connected to the cover 31. The base 30 constitutes the bottom surface portion 16 of the housing 15, the flange portion 19, and the lower portion 18 b of the peripheral wall portion 18. Therefore, the bottom surface portion 16 of the housing 15, the flange portion 19, and the lower portion 18 b of the peripheral wall portion 18 are one member. Are integrally formed. The cover 31 constitutes most of the upper portion 18 a of the peripheral wall portion 18 of the housing 15 and the shoulder portion 17 b of the top surface portion 17, and a relief portion 27 is formed in the cover 31. The lower end portion of the cover 31 is connected to the radially inner side of the upper end portion of the base 30. A circular opening 35 is formed in the upper central portion of the cover 31, and the cap 32 is attached to the cover 31 so that the cap 32 covers the opening 35. The cap 32 constitutes the top portion 17a of the top surface portion 17 of the housing 15 and the upper end portion of the shoulder portion 17b. Further, the cover 31 includes a motor holding portion 36 that extends inward and downward from the opening 35, and the motor 11 is attached to the motor holding portion 36 from below. Therefore, the motor 11 is suspended and held inside the cover 31. The power receiving connector 26 is disposed between the motor holding portion 36 of the cover 31 and the cap 32.

<Retaining ring 14>
The retaining ring 14 is attached to the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18 of the housing 15 of the main body 13. As described above, the external thread portion 21 is formed on the outer peripheral surface of the lower portion 18b of the peripheral wall portion 18 of the housing 15, and the internal thread portion 40 is formed on the inner peripheral surface of the retaining ring 14 correspondingly. The holding ring 14 is screwed to the main body 13 from above. The female thread portion 40 may be formed continuously over the entire circumference of the inner peripheral surface of the holding ring 14, but in this embodiment, a predetermined angular range of the entire circumference of the inner peripheral surface of the holding ring 14. Only formed. That is, the entire circumference of the inner peripheral surface of the retaining ring 14 is composed of an angle range in which the female screw portion 40 is formed and an angle range 41 in which the female screw portion 40 is not formed. The angle range 41 in which the female screw portion 40 is not formed is provided at two positions opposed to each other by 180 degrees. Therefore, the angle range in which the female screw portion 40 is formed is also provided at two positions with a circumferential interval. Yes. However, the number and arrangement of the angle range in which the female screw portion 40 is formed and the angle range 41 in which the female screw portion 40 is not formed may be arbitrarily changed.

  Further, the female screw portion 40 is formed only in the central portion in the axial direction (vertical direction) of the inner peripheral surface of the holding ring 14, and on the lower side of the female screw portion 40 on the inner peripheral surface of the holding ring 14. A smooth surface 42 in which the female screw portion 40 is not formed exists over the entire circumference. When the holding ring 14 is screwed to the main body 13 as shown in FIG. 5, the lower smooth surface 42 of the female screw portion 40 of the holding ring 14 is the smooth surface of the lower portion 18 b of the peripheral wall portion 18 of the housing 15 of the main body 13. Face 22 with a gap in the radial direction. In this way, a gap is formed between the lower smooth surface 42 of the female thread portion 40 of the retaining ring 14 and the smooth surface 22 of the lower portion 18b of the peripheral wall portion 18 of the housing 15 of the main body 13. The thickness is preferably equal to or greater than the thickness of the garment 100.

  The retaining ring 14 has a thin cylindrical shape whose radial dimension is smaller than the axial dimension. A flange portion 43 is provided around the lower end portion of the holding ring 14 so as to extend radially outward. The outer diameter of the flange portion 43 of the holding ring 14 is substantially the same as the outer diameter of the flange portion 19 of the main body 13. The lower end surface of the holding ring 14, that is, the lower surface of the flange portion 43 is a holding surface 43 a of the holding ring 14. The flange portion 43 of the retaining ring 14 extends substantially horizontally, and the holding surface 43a of the retaining ring 14 is a surface that is orthogonal to the axial direction of the retaining ring 14 and is a horizontal surface that is a smooth surface without irregularities. Yes.

  The garment 100 is sandwiched between the holding surface 43 a of the holding ring 14 and the holding surface 19 a of the main body 13. 4 and 5 show the garment 100 at the opening edge of the attachment hole 101 by a two-dot chain line. In this way, the holding surface 43a of the holding ring 14 and the holding surface 19a of the main body 13 face each other in parallel to hold the garment 100. Since the pressing protrusion 23 is formed on the holding surface 19a of the main body 13 as described above, the holding surface of the main body 13 is not held evenly across the entire circumference of the opening edge. The garment 100 is strongly pinched locally between the pressing protrusion 23 of 19a and the holding surface 43a of the holding ring 14. In the state where the garment 100 is not sandwiched, the holding surface 43 a of the holding ring 14 contacts the pressing protrusion 23. In a state where the holding surface 43 a of the holding ring 14 is in contact with the pressing projection 23, the portion between the holding surface 19 a of the main body 13 where the pressing projection 23 is not formed and the holding surface 43 a of the holding ring 14. A gap corresponding to the height of the pressing protrusion 23 is formed.

  On the outer peripheral surface of the holding ring 14, irregularities are formed to prevent slipping when the holding ring 14 is rotated. Although the uneven shape is arbitrary, in the present embodiment, the convex portions 44 and the concave portions 45 are alternately formed in the circumferential direction. The convex portions 44 and the concave portions 45 are alternately formed over the entire circumference. Note that the thickness of the retaining ring 14 is relatively thick in the convex portion 44, and the thickness of the retaining ring 14 is relatively thin in the concave portion 45.

  The garment fan 1 configured as described above is attached to the attachment hole 101 of the garment 100 as follows, for example. That is, the main body 13 is inserted into the attachment hole 101 from the front side of the garment 100. The housing 15 of the main body 13 projects through the attachment hole 101 to the back side of the garment 100. On the other hand, the flange portion 19 of the housing 15 cannot pass through the attachment hole 101 and comes into contact with the surface of the opening edge portion of the attachment hole 101 of the garment 100. The holding ring 14 is screwed onto the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18 of the housing 15 of the main body 13 protruding to the back side of the garment 100. Then, by tightening the holding ring 14 clockwise, the opening edge portion of the attachment hole 101 of the garment 100 is held between the flange portion 43 of the holding ring 14 and the flange portion 19 of the main body 13. Thus, the fan 1 for clothes can be attached to the clothes 100 by screwing the holding ring 14 to the main body 13. Conversely, when removing the garment fan 1 from the garment 100, the holding ring 14 is rotated counterclockwise to remove the holding ring 14 from the main body 13, thereby releasing the holding state of the garment 100. Is removed from the attachment hole 101 of the garment 100 to the front side.

  As described above, since the garment 100 can be held between the main body 13 and the retaining ring 14 by a simple operation of rotating the retaining ring 14, the garment fan 1 can be easily attached to the garment 100. Removal from 100 is also easy. Further, since the holding ring 14 is rotated to hold the garment 100 together with the main body 13, a conventional rubber belt is not required and the durability is excellent.

  In addition, since the pressing protrusion 23 is formed on the holding surface 19 a of the flange portion 19 of the main body 13, the pressing protrusion 23 can be strongly pressed against the garment 100, and the garment fan 1 is securely attached to the garment 100. Can do. Moreover, since the flange part 43 is provided in the holding ring 14, the dimension (width | variety) of the radial direction of the pinching surface 43a of the holding ring 14 can be expanded, and the stable attachment state is obtained.

  When the lower portion 18 b of the peripheral wall portion 18 of the main body 13 is inserted into or removed from the attachment hole 101 of the garment 100, the male screw portion 21 can slide with the opening edge of the attachment hole 101 of the garment 100. However, since the tip of the thread of the male screw portion 21 is rounded, the male screw portion 21 is not easily caught by the clothes 100, and the main body 13 can be smoothly inserted into and removed from the mounting hole 101. Further, a smooth surface 22 is formed below the male screw portion 21 on the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18 of the main body 13, and a smooth surface 42 is also formed below the female screw portion 40 of the holding ring 14. In the state where the holding ring 14 is screwed to the main body 13, the lower sliding surface 42 of the female screw portion 40 of the holding ring 14 and the lower surface 18 b of the peripheral wall portion 18 of the housing 15 of the main body 13. Is formed between the sliding surface 22 of the main body 13 and the sliding surface 42 of the retaining ring 14 even if the main body 13 is eccentric with respect to the attachment hole 101 of the clothing 100. 100 opening edges can be bent in. Therefore, even if the main body 13 is eccentric with respect to the attachment hole 101 of the garment 100, the garment fan 1 can be securely attached to the garment 100.

  In the present embodiment, the holding ring 14 is screwed onto the outer peripheral surface of the lower portion 18b of the peripheral wall portion 18 of the housing 15 of the main body 13. However, the holding ring 14 may be screwed to the housing 15 of the main body 13 by a configuration other than screws. You may make it mount | wear, rotating on the outer peripheral surface of the lower part 18b of the surrounding wall part 18. As shown in FIG. For example, FIGS. 14 to 17 show a configuration using the engagement groove 50 instead of the screw. As shown in FIG. 16, an engagement groove 50 is formed on the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18 of the housing 15. The engaging groove 50 includes an inclined groove 51 that extends obliquely downward, and a vertical groove 52 that extends in the vertical direction (axial direction) from the upper end portion of the inclined groove 51 to the upper end portion of the lower portion 18b of the peripheral wall portion 18. . The inclination angle of the inclined groove 51 with respect to the circumferential direction is preferably less than 45 degrees. The lower end portion of the inclined groove 51 is located in the middle in the vertical direction of the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18 and is located away from the flange portion 19. A pair of such engaging grooves 50 are formed to face the outer peripheral surface of the lower portion 18b of the peripheral wall portion 18 of the housing 15 by 180 degrees. However, the number and arrangement of the engaging grooves 50 are arbitrary.

  On the other hand, an engagement protrusion 60 that engages with the engagement groove 50 of the main body 13 is formed on the inner peripheral surface of the holding ring 14. The engagement protrusions 60 are formed corresponding to the number and arrangement of the engagement grooves 50 of the main body 13, and are protruded radially inward at two positions opposed to each other by 180 degrees in this embodiment. Yes. The shape of the engagement protrusion 60 is arbitrary, but may be, for example, a cylindrical shape. A protrusion 61 is formed on the outer peripheral surface of the holding ring 14 at a position corresponding to the engagement protrusion 60, and the protrusion 61 serves as a mark and is positioned on the radially inner side depending on the position of the protrusion 61. The position of the mating protrusion 60 can be grasped.

  14 and 15, when the retaining ring 14 is mounted on the main body 13, the engaging protrusion 60 of the retaining ring 14 is positioned above the vertical groove 52 of the engaging groove 50, and the retaining ring 14 is lowered therefrom. Thus, the engagement protrusion 60 is engaged with the longitudinal groove 52. Then, by rotating the holding ring 14 clockwise in plan view, the engagement protrusion 60 moves toward the lower end portion of the inclined groove 51. As the engaging protrusion 60 is guided to the inclined groove 51 of the engaging groove 50 in this way, the holding ring 14 gradually descends along the inclined groove 51 and approaches the flange portion 19 of the main body 13. Therefore, the garment 100 can be held between the flange portion 43 of the retaining ring 14 and the flange portion 19 of the main body 13.

  The main body 13 and the retaining ring 14 are preferably provided with a locking mechanism. Specifically, a locking groove 53 extending in the vertical direction is formed on the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18 of the housing 15 of the main body 13. The locking groove 53 is formed over the entire length in the vertical direction from the upper end to the lower end of the outer peripheral surface of the lower portion 18 b of the peripheral wall portion 18. One locking groove 53 may be provided, but in the present embodiment, a large number of locking grooves 53 are arranged in parallel in the circumferential direction. A group of the locking grooves 53 formed as a single set is provided as a pair facing each other by 180 degrees.

  On the other hand, the holding ring 14 includes a flexible piece 62 at one location on the entire circumference. A slit 63 is formed on each of the left and right sides (both sides in the circumferential direction) of the flexible piece 62. The slit 63 extends from the upper end of the holding ring 14 to the vicinity of the lower end of the holding ring 14. Therefore, the flexible piece 62 is connected to the other part of the holding ring 14 only at the lower end portion, and elastically deforms inward and outward in the radial direction with the lower end portion as a fulcrum. A locking protrusion 64 that locks in the locking groove 53 of the main body 13 is formed on the inner surface of the flexible piece 62. The locking protrusion 64 extends in the vertical direction, that is, along the axial direction of the holding ring 14. The vertical length of the locking protrusion 64 is shorter than that of the locking groove 53. The locking protrusion 64 is formed on the flexible piece 62.

  As described above, when the holding ring 14 is mounted on the main body 13 while rotating, the locking protrusions 64 of the holding ring 14 are sequentially locked in the locking grooves 53 of the main body 13. When the holding ring 14 is mounted on the main body 13, the locking protrusion 64 of the holding ring 14 is first locked in the rightmost locking groove 53 as viewed from the front. When the holding ring 14 is further rotated clockwise from the position in the plan view, the flexible piece 62 is elastically deformed radially outward to overcome the ridge between the locking grooves 53, and the left-side locking groove 53 again. That is, the locking protrusion 64 is sequentially locked like a latch from the right locking groove 53 to the left locking groove 53. Then, as shown in FIG. 15, when the engaging protrusion 60 of the holding ring 14 reaches the vicinity of the lower end of the engaging groove 50 of the main body 13, the leftmost of the group of many engaging grooves 53 as viewed from the front. The locking protrusion 64 is locked in the locking groove 53 positioned.

  In this way, when the locking protrusion 64 of the holding ring 14 is locked in the locking groove 53 of the main body 13, the holding ring 14 can be locked at that position, and loosening of the holding ring 14 is prevented. . Further, since a large number of the locking grooves 53 are arranged in parallel, the holding ring 14 is locked at that position even if the locking protrusion 64 is locked in any locking groove 53. Therefore, even if the thickness of the garment 100 increases or decreases, it can be easily accommodated. When the garment 100 is thin, the locking ridge 64 may be locked in the locking groove 53 on the left side. When the thickness is thick, the locking protrusion 64 may be locked in the locking groove 53 on the right side.

  The flexible piece 62 preferably projects a predetermined length above the upper end of the holding ring 14. By pushing the upward projecting portion 65 of the flexible piece 62 projecting upward from the upper end of the holding ring 14 radially outward with a finger, the flexible piece 62 is forcibly elastically deformed radially outward to engage the locking protrusion. 64 can be removed from the locking groove 53. In this state, the holding ring 14 can be removed from the main body 13 by rotating the holding ring 14 in the direction opposite to that at the time of mounting.

  Note that when the rotational operation force for rotating the holding ring 14 in the direction opposite to that when the retaining ring 14 is exceeded exceeds a predetermined value, the flexible piece 62 is reduced in diameter by the reaction force received by the locking protrusion 64 from the locking groove 53. It may be configured such that the locking protrusion 64 gets over the locking groove 53 by being elastically deformed outward in the direction. If comprised in this way, when removing the holding ring 14 from the main body 13, the operation which pushes the upward protrusion part 65 mentioned above to a radial direction outer side with a finger | toe becomes unnecessary, and it is convenient.

  Only one locking groove 53 may be formed. Further, the engagement protrusion 60 may be formed on the main body 13 and the engagement groove 50 may be formed on the holding ring 14. Similarly, a locking protrusion 64 may be formed on the main body 13 and a locking groove 53 may be formed on the holding ring 14.

  Moreover, although the flange part 43 was provided in the holding ring 14, it is good also as a structure which does not provide the flange part 43. FIG. However, by providing the flange portion 43, the width of the holding surface 43a of the holding ring 14 can be increased.
