＜３．スプールの詳細構成＞
図２は、スプール２０を上方から視た斜視図であり、図３は、スプール２０を下方から視た斜視図である。また、図４、図５は、上蓋部５０を取付け前のスプール２０の斜視図である。スプール２０は、シャフト３０と、胴部４０と、上蓋部５０と、弾性部材６０と、を備える。シャフト３０は、円柱状であり、上下に延びる中心軸Ｊを中心として回転する。 <3. Detailed spool configuration>
FIG. 2 is a perspective view of the spool 20 viewed from above, and FIG. 3 is a perspective view of the spool 20 viewed from below. 4 and 5 are perspective views of the spool 20 before the upper lid portion 50 is attached. The spool 20 includes a shaft 30, a body portion 40, an upper lid portion 50, and an elastic member 60. The shaft 30 has a columnar shape and rotates about a central axis J extending up and down.

胴部４０は、シャフト３０よりも径の大きい円板状に形成され、下部にシャフト３０が連結される。また、胴部４０は、径方向外面に靴紐Ｓが巻回される。 The body portion 40 is formed in a disk shape having a diameter larger than that of the shaft 30, and the shaft 30 is connected to the lower portion. Further, the shoelace S is wound around the outer surface of the body portion 40 in the radial direction.

胴部４０は、溝部４１と、上鍔部４２と、下鍔部４５と、係合凸部（第１凸部）４３と、収容凹部（第２凹部）４４と、連結凹部４６と、を有する。 The body portion 40 includes a groove portion 41, an upper flange portion 42, a lower flange portion 45, an engaging convex portion (first convex portion) 43, an accommodating concave portion (second concave portion) 44, and a connecting concave portion 46. Have.

溝部４１は、胴部４０の上面に配置され、中心軸Ｊを通って径方向に直線状に延びる。溝部４１の径方向の両端は、開放されており、溝部４１に靴紐Ｓが配置される。 The groove portion 41 is arranged on the upper surface of the body portion 40 and extends linearly in the radial direction through the central axis J. Both ends in the radial direction of the groove 41 are open, and the shoelace S is arranged in the groove 41.

胴部４０の上面は、溝部４１を挟んで第１領域４０Ａ及び第２領域４０Ｂに仕切られる。第１領域４０Ａ及び第２領域４０Ｂは、上面視において、半円状に形成され、第１領域４０Ａの上面の方が、第２領域４０Ｂの上面よりも軸方向上側に配置される。 The upper surface of the body portion 40 is partitioned into a first region 40A and a second region 40B with the groove portion 41 interposed therebetween. The first region 40A and the second region 40B are formed in a semicircular shape in a top view, and the upper surface of the first region 40A is arranged axially above the upper surface of the second region 40B.

上鍔部４２は、第１領域４０Ａにおいて、胴部４０の上端部から径向外側に突出する。上鍔部４２は、胴部４０の径方向外面に巻回される靴紐Ｓが、軸方向上側に抜けることを防止する。 The upper flange portion 42 projects radially outward from the upper end portion of the body portion 40 in the first region 40A. The upper collar portion 42 prevents the shoelace S wound around the radial outer surface of the body portion 40 from coming off upward in the axial direction.

下鍔部（鍔部）４５は、胴部４０の下端部から径方向外側に突出する。下鍔部４５は、胴部４０の径方向外面に巻回される靴紐Ｓを支持し、靴紐Ｓが軸方向下側に抜けることを防止する。 The lower flange portion (flange portion) 45 projects radially outward from the lower end portion of the body portion 40. The lower collar portion 45 supports the shoelace S wound around the radial outer surface of the body portion 40, and prevents the shoelace S from coming off downward in the axial direction.

収容凹部４４は、第２領域４０Ｂにおいて、胴部４０の上面から軸方向下側に凹む。収容凹部４４は、溝部４１と連通し、上面視において、溝部４１の延びる方向に対して直交する方向に延びる。収容凹部４４の内部には弾性部材６０が配置される。 The accommodating recess 44 is axially downwardly recessed from the upper surface of the body portion 40 in the second region 40B. The accommodating recess 44 communicates with the groove portion 41 and extends in a direction orthogonal to the extending direction of the groove portion 41 in a top view. An elastic member 60 is arranged inside the accommodating recess 44.

係合凸部４３は、第２領域４０Ｂにおいて、胴部４０の上面から軸方向上側に突出する。係合凸部４３は、収容凹部４４を挟んで溝部４１と径方向に対向して配置される。係合凸部４３は、上面視においてＣ字状に形成され、収容凹部の端部を囲む。 The engaging convex portion 43 projects axially upward from the upper surface of the body portion 40 in the second region 40B. The engaging convex portion 43 is arranged to face the groove portion 41 in the radial direction with the accommodating concave portion 44 interposed therebetween. The engaging convex portion 43 is formed in a C shape in a top view and surrounds the end portion of the accommodating concave portion.

係合凸部４３は、一対の保持部４３１を有する。一対の保持部４３１は、係合凸部４３の周方向の両端部から内側に凹み、径方向（溝部４１に直交する方向）に延びる溝状に形成される。すなわち、係合凸部４３の径方向外面は、一対の保持部４３１が形成されている。一対の保持部４３１は、平行に延び、径方向の両端は、それぞれ開放されている。本実施形態では、一対の保持部４３１は、溝部４１の延びる方向と直交する方向に延びる。また、保持部４３１の下壁部４３１ａの上面と、胴部４０の上面とは、面一に形成されている（図５参照）。 The engaging convex portion 43 has a pair of holding portions 431. The pair of holding portions 431 are formed in a groove shape that is recessed inward from both ends in the circumferential direction of the engaging convex portion 43 and extends in the radial direction (direction orthogonal to the groove portion 41). That is, a pair of holding portions 431 are formed on the radial outer surface of the engaging convex portion 43. The pair of holding portions 431 extend in parallel, and both ends in the radial direction are open. In the present embodiment, the pair of holding portions 431 extend in a direction orthogonal to the extending direction of the groove portion 41. Further, the upper surface of the lower wall portion 431a of the holding portion 431 and the upper surface of the body portion 40 are formed flush with each other (see FIG. 5).

＜４．上蓋部の詳細構成＞
図６、図７は、上蓋部５０の斜視図及び上面図である。上蓋部５０は、上面視において、半円板状であり、第２領域４０Ｂにおいて、胴部４０の上面に配置される。上蓋部５０は、貫通孔（第１凹部）５１と、一対の突出部５２と、押圧片（第３凸部）５３と、を有する。貫通孔５１は、上蓋部５０を軸方向に貫通する。なお、貫通孔５１の代わりに上蓋部５０の下面から軸方向上側に凹む非貫通の凹部を設けてもよい。 <4. Detailed configuration of the upper lid>
6 and 7 are a perspective view and a top view of the upper lid portion 50. The upper lid portion 50 has a semicircular shape in the top view, and is arranged on the upper surface of the body portion 40 in the second region 40B. The upper lid portion 50 has a through hole (first concave portion) 51, a pair of protruding portions 52, and a pressing piece (third convex portion) 53. The through hole 51 penetrates the upper lid portion 50 in the axial direction. Instead of the through hole 51, a non-penetrating recess recessed from the lower surface of the upper lid portion 50 to the upper side in the axial direction may be provided.

一対の突出部５２は、貫通孔５１の周方向内面に配置され、内側に突出する。すなわち、貫通孔５１の内面は、径方向に延びる一対の突出部５２が形成されている。一対の突出部５２は、平行に延びる。 The pair of projecting portions 52 are arranged on the inner surface in the circumferential direction of the through hole 51 and project inward. That is, a pair of protrusions 52 extending in the radial direction are formed on the inner surface of the through hole 51. The pair of protrusions 52 extend in parallel.

上蓋部５０を胴部４０に取付ける際に、弾性部材６０を圧縮した状態で突出部５２を保持部４３１の外周側の開放端から保持部４３１内に挿入する。これにより、突出部５２は、保持部４３１により摺動可能に保持される。すなわち、保持部４３１は、突出部５２を径方向に摺動可能に保持する。このとき、係合凸部（第１凸部）４３と貫通孔（第１凹部）５１とが、軸方向に係合する。 When the upper lid portion 50 is attached to the body portion 40, the protruding portion 52 is inserted into the holding portion 431 from the open end on the outer peripheral side of the holding portion 431 in a state where the elastic member 60 is compressed. As a result, the protruding portion 52 is slidably held by the holding portion 431. That is, the holding portion 431 holds the protruding portion 52 so as to be slidable in the radial direction. At this time, the engaging convex portion (first convex portion) 43 and the through hole (first concave portion) 51 engage in the axial direction.

押圧片５３は、貫通孔５１の周縁に配置され、上蓋部５０の下面から軸方向下側に突出する。押圧片５３は、収容凹部４４の内部に配置される。押圧片５３の下端は、収容凹部４４の底面と接触する。また、押圧片５３は、収容凹部４４の延びる方向にスライドする。また、押圧片５３は、弾性部材６０の一端と接触し、溝部４１側に付勢される。これにより、靴紐Ｓは、付勢された押圧片５３と溝部４１の側壁４１ａとにより挟まれ、溝部４１内に保持される。これにより、靴紐Ｓが、溝部４１から外れることを防止できる。また、上蓋部５０が、溝部４１の軸方向上側を覆う。従って、靴紐Ｓが、溝部４１の軸方向上側に外れることをより防止できる。 The pressing piece 53 is arranged on the peripheral edge of the through hole 51, and projects downward in the axial direction from the lower surface of the upper lid portion 50. The pressing piece 53 is arranged inside the accommodating recess 44. The lower end of the pressing piece 53 comes into contact with the bottom surface of the accommodating recess 44. Further, the pressing piece 53 slides in the extending direction of the accommodating recess 44. Further, the pressing piece 53 comes into contact with one end of the elastic member 60 and is urged toward the groove 41 side. As a result, the shoelace S is sandwiched between the urged pressing piece 53 and the side wall 41a of the groove 41, and is held in the groove 41. This makes it possible to prevent the shoelace S from coming off the groove 41. Further, the upper lid portion 50 covers the upper side of the groove portion 41 in the axial direction. Therefore, it is possible to further prevent the shoelace S from coming off to the upper side in the axial direction of the groove portion 41.

また、上蓋部５０を胴部４０に容易に取付けられる。従って、スプール２０の部品点数を減らして製造コストを下げるとともに組立作業性を向上することができる。 Further, the upper lid portion 50 can be easily attached to the body portion 40. Therefore, the number of parts of the spool 20 can be reduced, the manufacturing cost can be reduced, and the assembly workability can be improved.

＜５．胴部とシャフトの取付け構造＞
図８はスプール２０の縦断面図である。シャフト３０は、連結部３１を有する。連結部３１は、シャフト３０の上端部から径方向外側に突出して環状に形成される。連結凹部４６は、胴部４０の下面から軸方向上側に凹むとともに、連結部３１が内部に配置される。このとき、連結部３１の上面が、接着剤を介して胴部４０の下面と接触する。連結部３１を設けることにより、シャフト３０と胴部４０との接触面積が大きくなり、強固に連結することができる。 <5. Body and shaft mounting structure>
FIG. 8 is a vertical sectional view of the spool 20. The shaft 30 has a connecting portion 31. The connecting portion 31 projects radially outward from the upper end portion of the shaft 30 and is formed in an annular shape. The connecting recess 46 is recessed from the lower surface of the body portion 40 to the upper side in the axial direction, and the connecting portion 31 is arranged inside. At this time, the upper surface of the connecting portion 31 comes into contact with the lower surface of the body portion 40 via the adhesive. By providing the connecting portion 31, the contact area between the shaft 30 and the body portion 40 is increased, and the shaft 30 can be firmly connected.

また、シャフト３０の胴部４０との接触面は、シャフト３０の胴部４０との非接触面よりも面粗度が大きい。また、シャフト３０は、上端部において、連結凹部４６に接触する径方向外面の面粗度が、連結凹部４６に接触する上面の面粗度よりも大きい。これにより、シャフト３０と胴部４０との密着性が向上し、より強固に連結できる。なお、本実施形態では、接着剤を介して胴部４０とシャフト３０とを連結したが、接着剤を用いずにインサート成形により、胴部４０とシャフト３０とを連結してもよい。 Further, the contact surface of the shaft 30 with the body portion 40 has a larger surface roughness than the non-contact surface of the shaft 30 with the body portion 40. Further, at the upper end of the shaft 30, the surface roughness of the radial outer surface in contact with the connecting recess 46 is larger than the surface roughness of the upper surface in contact with the connecting recess 46. As a result, the adhesion between the shaft 30 and the body portion 40 is improved, and the shaft 30 can be more firmly connected. In the present embodiment, the body portion 40 and the shaft 30 are connected via an adhesive, but the body portion 40 and the shaft 30 may be connected by insert molding without using an adhesive.

また、シャフト３０を構成する材料は、胴部４０を構成する材料よりも剛性が高い。具体的には、シャフト３０が、金属部材から成り、胴部４０が樹脂部材から成る。これにより、シャフト３０の耐久性及び低騒音性を向上できる。 Further, the material constituting the shaft 30 has higher rigidity than the material constituting the body portion 40. Specifically, the shaft 30 is made of a metal member, and the body portion 40 is made of a resin member. Thereby, the durability and low noise level of the shaft 30 can be improved.

なお、本実施形態では、係合凸部（第１凸部）４３は、胴部４０の上面に配置され、貫通孔（第１凹部）５１は、上蓋部５０に配置されたが、軸方向下側に突出する係合凸部（第１凸部）４３を上蓋部５０の下面に配置し、胴部４０の上面に軸方向下側に凹む非貫通の凹部（第１凹部）を設けてもよい。 In the present embodiment, the engaging convex portion (first convex portion) 43 is arranged on the upper surface of the body portion 40, and the through hole (first concave portion) 51 is arranged on the upper lid portion 50, but in the axial direction. An engaging convex portion (first convex portion) 43 protruding downward is arranged on the lower surface of the upper lid portion 50, and a non-penetrating concave portion (first concave portion) recessed downward in the axial direction is provided on the upper surface of the body portion 40. May be good.

また、一対の保持部４３１を係合凸部４３の周方向外面に配置し、一対の突出部５２を貫通孔５１の周方向内面に配置したが、一対の保持部４３１を貫通孔５１の周方向内面に配置し、一対の突出部５２を係合凸部４３の周方向外面に配置してもよい。 Further, the pair of holding portions 431 are arranged on the circumferential outer surface of the engaging convex portion 43, and the pair of protruding portions 52 are arranged on the circumferential inner surface of the through hole 51, but the pair of holding portions 431 are arranged around the through hole 51. It may be arranged on the inner surface in the direction, and the pair of protrusions 52 may be arranged on the outer surface in the circumferential direction of the engaging convex portion 43.

また、収容凹部４４及び押圧片５３を省いてもよい。この場合、係合凸部（第１凸部）４３の径方向外面と貫通孔（第１凹部）５１の径方向内面との間に弾性部材６０を配置することができる。これにより、スプール２０の構造を簡素化して製造コストをより下げることができる。 Further, the accommodating recess 44 and the pressing piece 53 may be omitted. In this case, the elastic member 60 can be arranged between the radial outer surface of the engaging convex portion (first convex portion) 43 and the radial inner surface of the through hole (first concave portion) 51. As a result, the structure of the spool 20 can be simplified and the manufacturing cost can be further reduced.

＜第２実施形態＞
次に、本発明の第２実施形態について説明する。図９は、第２実施形態に係るスプール２０を上方から視た斜視図であり、上蓋部５０を取付け前の状態を示す。図１０は、上蓋部５０を下方から視た斜視図であり、図１１は、スプール２０の縦断面図である。説明の便宜上、前述の図１～図８に示す第１実施形態と同様の部分には同一の符号を付す。第２実施形態では胴部４０と上蓋部５０との取付け構造が第１実施形態とは異なる。その他の部分は第１実施形態と同様である。 <Second Embodiment>
Next, a second embodiment of the present invention will be described. FIG. 9 is a perspective view of the spool 20 according to the second embodiment as viewed from above, and shows a state before the upper lid portion 50 is attached. FIG. 10 is a perspective view of the upper lid portion 50 as viewed from below, and FIG. 11 is a vertical sectional view of the spool 20. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. 1 to 8 described above are designated by the same reference numerals. In the second embodiment, the mounting structure of the body portion 40 and the upper lid portion 50 is different from that of the first embodiment. Other parts are the same as those in the first embodiment.

胴部４０は、溝部４１と、上鍔部４２と、下鍔部４５と、胴凹部（第１凹部）２４３と、を有する。胴凹部２４３は、第２領域４０Ｂにおいて、胴部４０の上面から軸方向下側に凹む。胴凹部２４３は、溝部４１と連通し、上面視において、矩形に形成される。 The body portion 40 has a groove portion 41, an upper flange portion 42, a lower collar portion 45, and a body recess (first recess) 243. The body recess 243 is recessed in the second region 40B from the upper surface of the body portion 40 to the lower side in the axial direction. The body recess 243 communicates with the groove 41 and is formed in a rectangular shape in a top view.

胴凹部２４３は、係合凹部２４３ａを有する（図１１参照）。係合凹部２４３ａは、溝部４１と径方向に対向し、胴凹部２４３の径方向内面から径方向外側に凹む。 The body recess 243 has an engaging recess 243a (see FIG. 11). The engaging recess 243a faces the groove 41 in the radial direction and is recessed radially outward from the radial inner surface of the body recess 243.

上蓋部５０は、係合爪（第１凸部）２５４と、位置決め凸部２５５と、支持突起部２５６と、を有する。上蓋部５０を胴部４０に取り付けた際に、支持突起部２５６、位置決め凸部２５５、係合爪２５４の順に溝部４１から遠ざかる位置に配置される。 The upper lid portion 50 has an engaging claw (first convex portion) 254, a positioning convex portion 255, and a support protrusion portion 256. When the upper lid portion 50 is attached to the body portion 40, the support protrusion portion 256, the positioning convex portion 255, and the engaging claw 254 are arranged in this order at positions away from the groove portion 41.

係合爪２５４は、スナップフィットタイプであり、上蓋部５０の下面から軸方向下側に突出し、突起部２５４ａを有する。突起部２５４ａは、係合爪２５４の先端から径方向外側に突出する。 The engaging claw 254 is a snap-fit type, protrudes downward in the axial direction from the lower surface of the upper lid portion 50, and has a protruding portion 254a. The protrusion 254a projects radially outward from the tip of the engaging claw 254.

位置決め凸部２５５は、上蓋部５０の下面から軸方向下側に突出し、胴凹部２４３の内部に配置される。位置決め凸部２５５の下端は、胴凹部２４３の底面と接触し、上蓋部５０を軸方向に支持する。位置決め凸部２５５を設けることにより、上蓋部５０を胴部４０に容易に取付けできる。 The positioning convex portion 255 protrudes downward in the axial direction from the lower surface of the upper lid portion 50 and is arranged inside the body recess 243. The lower end of the positioning convex portion 255 contacts the bottom surface of the body concave portion 243 and supports the upper lid portion 50 in the axial direction. By providing the positioning convex portion 255, the upper lid portion 50 can be easily attached to the body portion 40.

支持突起部２５６は、上蓋部５０の内周側の端面から径方向に突出する。支持突起部２５６は、溝部４１の側壁４１ａと接触する。 The support protrusion 256 protrudes radially from the end surface on the inner peripheral side of the upper lid portion 50. The support protrusion 256 comes into contact with the side wall 41a of the groove 41.

上蓋部５０を胴部４０に取付ける際に、支持突起部２５６を溝部４１の側壁４１ａと接触させながら、係合爪２５４及び位置決め凸部２５５を胴凹部２４３に挿入する。このとき、係合爪２５４は弾性変形して胴凹部２４３の径方向内面と摺動し、突起部２５４ａが、係合凹部２４３ａの内部に配置される。このとき、係合凹部２４３ａは、突起部２５４ａと係合する。これにより、係合爪２５４（第１凸部）と胴凹部（第１凹部）２４３とが、軸方向に係合する。また、靴紐Ｓは、溝部４１の側壁４１ａと、位置決め凸部２５５と、支持突起部２５６と、により囲まれ、溝部４１内に保持される（図１１参照）。また、上蓋部５０が、溝部４１の軸方向上側の少なくとも一部を覆う。従って、上蓋部５０は、靴紐Ｓが溝部４１の軸方向上側に外れることを防止できる。これにより、第１実施形態と同様の効果が得られる。 When the upper lid portion 50 is attached to the body portion 40, the engaging claw 254 and the positioning convex portion 255 are inserted into the body recess 243 while the support protrusion portion 256 is in contact with the side wall 41a of the groove portion 41. At this time, the engaging claw 254 elastically deforms and slides on the radial inner surface of the body recess 243, and the protrusion 254a is arranged inside the engaging recess 243a. At this time, the engaging recess 243a engages with the protrusion 254a. As a result, the engaging claw 254 (first convex portion) and the body concave portion (first concave portion) 243 are engaged in the axial direction. Further, the shoelace S is surrounded by the side wall 41a of the groove 41, the positioning protrusion 255, and the support protrusion 256, and is held in the groove 41 (see FIG. 11). Further, the upper lid portion 50 covers at least a part of the groove portion 41 on the upper side in the axial direction. Therefore, the upper lid portion 50 can prevent the shoelace S from coming off to the upper side in the axial direction of the groove portion 41. As a result, the same effect as that of the first embodiment can be obtained.

なお、本実施形態では、係合爪（第１凸部）２５４は、上蓋部５０の下面に配置され、胴凹部（第１凹部）５１は、胴部４０に配置されたが、軸方向上側に突出する係合爪（第１凸部）２５４を胴部４０の上面に配置し、上蓋部５０の下面に軸方向上側に凹む凹部（第１凹部）を設けてもよい。 In the present embodiment, the engaging claw (first convex portion) 254 is arranged on the lower surface of the upper lid portion 50, and the body recess (first concave portion) 51 is arranged on the body portion 40, but the upper side in the axial direction. The engaging claw (first convex portion) 254 protruding from the surface may be arranged on the upper surface of the body portion 40, and a concave portion (first concave portion) recessed upward in the axial direction may be provided on the lower surface of the upper lid portion 50.

また、係合爪２５４の先端に係合凹部２４３ａを設け、胴凹部２４３の径方向内面に係合凹部と係合する突起部２５４ａを設けてもよい。 Further, an engaging recess 243a may be provided at the tip of the engaging claw 254, and a protrusion 254a that engages with the engaging recess may be provided on the radial inner surface of the body recess 243.

＜第３実施形態＞
次に、本発明の第３実施形態について説明する。図１２は、第３実施形態に係るスプール２０を上方から視た斜視図であり、上蓋部５０を取付け前の状態を示す。図１３は、上蓋部５０を下方から視た斜視図であり、図１４は、スプール２０の縦断面図である。説明の便宜上、前述の図１～図８に示す第１実施形態と同様の部分には同一の符号を付す。第３実施形態では胴部４０と上蓋部５０との取付け構造が第１実施形態とは異なる。その他の部分は第１実施形態と同様である。 <Third Embodiment>
Next, a third embodiment of the present invention will be described. FIG. 12 is a perspective view of the spool 20 according to the third embodiment as viewed from above, and shows a state before the upper lid portion 50 is attached. FIG. 13 is a perspective view of the upper lid portion 50 as viewed from below, and FIG. 14 is a vertical sectional view of the spool 20. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. 1 to 8 described above are designated by the same reference numerals. In the third embodiment, the mounting structure of the body portion 40 and the upper lid portion 50 is different from that of the first embodiment. Other parts are the same as those in the first embodiment.

胴部４０は、溝部４１と、下鍔部４５と、一対の胴凸部（第１凸部）３４３ａ、３４３ｂと、連結凹部４６と、を有する。胴部４０の上面は、第１領域４０Ａ及び第２領域４０Ｂにおいて、軸方向の高さが同じ位置に配置される。 The body portion 40 has a groove portion 41, a lower flange portion 45, a pair of body convex portions (first convex portions) 343a and 343b, and a connecting concave portion 46. The upper surface of the body portion 40 is arranged at the same axial height in the first region 40A and the second region 40B.

胴凸部３４３ａ及び胴凸部３４３ｂは、溝部４１を挟んで径方向に対向する。すなわち、胴凸部（第１凸部）３４３ａ、３４３ｂは、胴部４０の上面に配置されるとともに、溝部４１を挟んで径方向に対向して一対設けられる。胴凸部３４３ａは、第１領域４０Ａにおいて、胴部４０の上面から軸方向上側に突出する。胴凸部３４３ｂは、第２領域４０Ｂにおいて、胴部４０の上面から軸方向上側に突出する。 The body convex portion 343a and the body convex portion 343b face each other in the radial direction with the groove portion 41 interposed therebetween. That is, the body convex portions (first convex portions) 343a and 343b are arranged on the upper surface of the body portion 40, and a pair of the body convex portions (first convex portions) are provided so as to face each other in the radial direction with the groove portion 41 interposed therebetween. The body convex portion 343a projects axially upward from the upper surface of the body portion 40 in the first region 40A. The body convex portion 343b projects axially upward from the upper surface of the body portion 40 in the second region 40B.

胴凸部３４３ａ、３４３ｂは、軸方向の先端から径方向外側に突出するフランジ部３４４ａ、３４４ｂをそれぞれ有する。フランジ部３４４ａ、３４４ｂは、曲面部３４５ａ、３４５ｂと、平面部３４６ａ、３４６ｂと、をそれぞれ有する。曲面部３４５ａ、３４５ｂは、溝部４１と径方向反対側にそれぞれ突出し、径方向外側に凸状に形成されている。平面部３４６ａ、３４６ｂは、曲面部３４５ａ、３４５ｂの両側部に配置され、平面状に形成されている。 The body convex portions 343a and 343b each have flange portions 344a and 344b protruding radially outward from the axial tip. The flange portions 344a and 344b have curved surface portions 345a and 345b and flat surface portions 346a and 346b, respectively. The curved surface portions 345a and 345b project from the groove portion 41 on the opposite side in the radial direction, and are formed in a convex shape on the outer side in the radial direction. The flat surface portions 346a and 346b are arranged on both side portions of the curved surface portions 345a and 345b and are formed in a planar shape.

上蓋部５０は、円板状であり、上蓋部５０の径は、胴部４０の径よりも大きい。上蓋部５０は、貫通孔（第１凹部）３５１と、一対の架橋片３５２と、を有する。貫通孔３５１は、上蓋部５０を軸方向に貫通する。なお、貫通孔３５１の代わりに上蓋部５０の下面から軸方向上側に凹む非貫通の凹部を設けてもよい。 The upper lid portion 50 has a disk shape, and the diameter of the upper lid portion 50 is larger than the diameter of the body portion 40. The upper lid portion 50 has a through hole (first recess) 351 and a pair of cross-linking pieces 352. The through hole 351 penetrates the upper lid portion 50 in the axial direction. Instead of the through hole 351, a non-penetrating recess recessed from the lower surface of the upper lid portion 50 to the upper side in the axial direction may be provided.

貫通孔３５１は、一対の係合片３５１ａ、３５１ｂを有する。一対の係合片３５１ａ、３５１ｂは、貫通孔３５１の径方向内面に配置されるとともに、径方向内側に突出し、径方向に対向する（図１４参照）。係合片３５１ａ、３５１ｂは、一対の架橋片３５２に周方向に挟まれ、平面状に形成されている。一対の架橋片３５２は、貫通孔３５１の内面から径方向に突出する。具体的には、一対の架橋片３５２は、一方の係合片３５１ａと他方の係合片３５１ｂとを架橋して形成される。すなわち、架橋片３５２の一端は、一方の係合片３５１ａと連結し、架橋片３５２の他端は、他方の係合片３５１ｂと連結する。また、一対の架橋片３５２は、それぞれ径方向外側に凸の円弧状に形成されている。このとき、一対の架橋片３５２及び一対の係合片３５１ａ、３５１ｂで囲まれる貫通孔３５１の内周縁の径は、フランジ部３４４ａ、３４４ｂの外周縁の径よりもわずかに大きい。また、一対の架橋片３５２は、下面から軸方向下側に突出する蓋突起部３５２ａをそれぞれ有する。 The through hole 351 has a pair of engaging pieces 351a and 351b. The pair of engaging pieces 351a and 351b are arranged on the radial inner surface of the through hole 351 and project radially inward and face each other in the radial direction (see FIG. 14). The engaging pieces 351a and 351b are sandwiched by a pair of cross-linking pieces 352 in the circumferential direction and are formed in a planar shape. The pair of crosslinked pieces 352 project radially from the inner surface of the through hole 351. Specifically, the pair of cross-linking pieces 352 is formed by cross-linking one engaging piece 351a and the other engaging piece 351b. That is, one end of the cross-linked piece 352 is connected to one engaging piece 351a, and the other end of the cross-linked piece 352 is connected to the other engaging piece 351b. Further, each of the pair of cross-linking pieces 352 is formed in an arc shape that is convex outward in the radial direction. At this time, the diameter of the inner peripheral edge of the through hole 351 surrounded by the pair of bridging pieces 352 and the pair of engaging pieces 351a and 351b is slightly larger than the diameter of the outer peripheral edge of the flange portions 344a and 344b. Further, each of the pair of cross-linking pieces 352 has a lid protrusion 352a projecting downward in the axial direction from the lower surface.

上蓋部５０を胴部４０に取付ける際に、一対の係合片３５１ａ、３５１ｂと平面部３４６ａ、３４６ｂとを周方向に一致させて胴凸部３４３ａ、３４３ｂを貫通孔３５１に挿入する。 When the upper lid portion 50 is attached to the body portion 40, the body convex portions 343a and 343b are inserted into the through holes 351 so that the pair of engaging pieces 351a and 351b and the flat surface portions 346a and 346b are aligned in the circumferential direction.

次に、上蓋部５０を周方向に回転させる。これにより、一対の係合片３５１ａ、３５１ｂの径方向内面は、胴凸部３４３ａ、３４３ｂの径方向外面を摺動して周方向に移動する。その後、蓋突起部３５２ａが、溝部４１に嵌合する。このとき、上蓋部５０が、胴部４０に対して周方向に係止される。 Next, the upper lid portion 50 is rotated in the circumferential direction. As a result, the radial inner surface of the pair of engaging pieces 351a and 351b slides on the radial outer surface of the body convex portions 343a and 343b and moves in the circumferential direction. After that, the lid protrusion 352a fits into the groove 41. At this time, the upper lid portion 50 is locked to the body portion 40 in the circumferential direction.

また、一対の係合片３５１ａ、３５１ｂが、曲面部３４５ａ、３４５ｂにおいて、フランジ部３４４ａ、３４４ｂと、胴部４０の上面と、で軸方向に挟まれる。すなわち、一対の係合片３５１ａ、３５１ｂは、胴凸部（第１凸部）３４３ａ、３４３ｂを挟んでフランジ部３４４ａ、３４４ｂと軸方向に接触する。このとき、胴凸部（第１凸部）３４３ａ、３４３ｂと貫通孔（第１凹部）３５１とが、軸方向に係合する。また、上蓋部５０が、溝部４１の軸方向上側を覆う。従って、上蓋部５０は、靴紐Ｓが溝部４１の軸方向上側に外れることを防止できる。これにより、第１実施形態と同様の効果が得られる。 Further, the pair of engaging pieces 351a and 351b are axially sandwiched between the flange portions 344a and 344b and the upper surface of the body portion 40 in the curved surface portions 345a and 345b. That is, the pair of engaging pieces 351a and 351b are in axial contact with the flange portions 344a and 344b with the body convex portion (first convex portion) 343a and 343b interposed therebetween. At this time, the body convex portion (first convex portion) 343a and 343b and the through hole (first concave portion) 351 engage in the axial direction. Further, the upper lid portion 50 covers the upper side of the groove portion 41 in the axial direction. Therefore, the upper lid portion 50 can prevent the shoelace S from coming off to the upper side in the axial direction of the groove portion 41. As a result, the same effect as that of the first embodiment can be obtained.

また、溝部４１を挟んで径方向に対向する一対の胴凸部（第１凸部）３４３ａ、３４３ｂを一対の係合片３５１ａ、３５１ｂで、挟むことにより、スプール２０の重心軸を中心軸Ｊに容易に一致させることができる。 Further, by sandwiching the pair of body convex portions (first convex portions) 343a and 343b facing each other in the radial direction with the pair of engaging pieces 351a and 351b sandwiching the groove portion 41, the center of gravity axis of the spool 20 is centered on the central axis J. Can be easily matched to.

なお、本実施形態では、一対の胴凸部（第１凸部）３４３ａ、３４３ｂは、胴部４０の上面に配置され、貫通孔３５１は、上蓋部５０に配置されたが、軸方向下側に突出する胴凸部（第１凸部）３４３ａ、３４３ｂを上蓋部５０の下面に配置し、胴部４０の上面に軸方向下側に凹む非貫通の凹部（第１凹部）を設けてもよい。 In the present embodiment, the pair of body convex portions (first convex portions) 343a and 343b are arranged on the upper surface of the body portion 40, and the through hole 351 is arranged on the upper lid portion 50, but on the lower side in the axial direction. Even if the body convex portion (first convex portion) 343a and 343b protruding from the body is arranged on the lower surface of the upper lid portion 50 and the upper surface of the body portion 40 is provided with a non-penetrating concave portion (first concave portion) recessed downward in the axial direction. good.

また、一対の胴凸部（第１凸部）３４３ａ、３４３ｂを設けたが、胴凸部３４３ａ、３４３ｂの一方のみ設けてもよい。胴凸部３４３ａ、３４３ｂの一方でも上蓋部５０を胴部４０に取付けることができる。 Further, although the pair of body convex portions (first convex portions) 343a and 343b are provided, only one of the body convex portions 343a and 343b may be provided. The upper lid portion 50 can be attached to the body portion 40 by either one of the body convex portions 343a and 343b.

また、一対の架橋片３５２は、一方の係合片３５１ａと他方の係合片３５１ｂとを架橋して形成されているが、架橋片３５２の一端のみを係合片３５１ａに連結させてもよい。 Further, although the pair of cross-linked pieces 352 is formed by cross-linking one engaging piece 351a and the other engaging piece 351b, only one end of the cross-linked piece 352 may be connected to the engaging piece 351a. ..
