Description

本発明は、自転車のペダルをペダルクランクに対して簡単に着脱できるようにするための自転車ペダル着脱装置に関するものである。   The present invention relates to a bicycle pedal attaching / detaching device for easily attaching / detaching a bicycle pedal to / from a pedal crank.

自転車に乗る練習をする場合に、ペダルを取外して両足を楽に地面に着けられるようにしておくことがある。すなわち足を地面につけられる状態で低速で走りながらハンドル操作を行い、バランスのとり方を体得するものである。このような練習ではペダルが足に干渉しないようにペダルを取外すのが望ましい。   When practicing riding a bicycle, the pedal may be removed so that both feet can be easily put on the ground. In other words, the steering wheel operation is performed while running at a low speed while the foot is placed on the ground, so as to learn how to balance. In such practice, it is desirable to remove the pedal so that the pedal does not interfere with the foot.

また新しい自転車を自転車販売店に納入する時には、ペダルを取外して収納箱に収納しておくことがある。このようにすれば収納箱を小さくでき運搬が楽になり収納スペースが小さくなり都合が良いからである。   When delivering a new bicycle to a bicycle dealer, the pedal may be removed and stored in a storage box. This is because the storage box can be made small in this way, transporting is facilitated, and the storage space is reduced, which is convenient.

さらに自転車を物置などに入れておく場合に、ペダルを容易に取外すことができれば、収納スペースが小さくなって都合がよい。   Furthermore, when the bicycle is put in a storeroom or the like, if the pedal can be easily removed, the storage space is advantageously reduced.

このようにペダルを容易に着脱可能にするため特許文献１，２に示すものが提案されている。特許文献１には、ペダルクランクの回動端にペダル受具（ペダル受筒）を螺入し、このペダル受具にペダル軸（ペダル支持軸）を貫挿しこのペダル軸の先端に設けた環状周溝（環状溝）に、カール状の係止リング１４を係止させるものが示されている。引用文献２には、ペダルクランクに取付けた筒体の内側（内周面）に係止体を装着し、この筒体に挿入したペダル軸にこの係止体を係合させることによりペダルをクランクに固定するものが示されている。   In order to make the pedal easily attachable / detachable as described above, those shown in Patent Documents 1 and 2 have been proposed. In Patent Document 1, a pedal holder (pedal receiving cylinder) is screwed into a rotating end of a pedal crank, and a pedal shaft (pedal support shaft) is inserted into the pedal receiver so as to be provided at the tip of the pedal shaft. A structure in which a curled locking ring 14 is locked in a circumferential groove (annular groove) is shown. In Cited Document 2, a locking body is mounted on the inner side (inner peripheral surface) of a cylinder attached to the pedal crank, and the pedal is cranked by engaging the locking body with a pedal shaft inserted into the cylinder. What is fixed to is shown.

特開平１１−２０８５６４号JP-A-11-208564 特開２０００−２８９６８０号JP 2000-289680 A

特許文献１に記載されたものは、環状周溝を両側から挟む一対の半円弧状の係合部を１本のワイヤを略Ω字状に折曲した係止リングを着脱するものである。ここに係止リングには抜止係止具を一体形成し、この抜止係止具を指先で掴んで着脱する。すなわち、ペダルクランクにペダル固定具（ケース）を固定し、このペダル固定具に設けた収納部に係止リングと一体の抜止係止具をペダルクランクと平行に挿抜するものである。   In Patent Document 1, a pair of semicircular arc-shaped engaging portions sandwiching an annular circumferential groove from both sides is attached and detached with a locking ring in which one wire is bent into a substantially Ω shape. The locking ring is integrally formed with a retaining latch, and the retaining latch is grasped with a fingertip and attached or detached. That is, a pedal fixing tool (case) is fixed to the pedal crank, and a locking stopper integrated with the locking ring is inserted into and removed from a storage portion provided in the pedal fixing tool in parallel with the pedal crank.

この場合、抜止係止具を挿抜する際には、係止リングを環状周溝内で一度拡開させる必要があり、大きい力を必要とする。このためペダル固定具（ケース）と抜止係止具とを左右の手で別々に掴んで作業することが必要になり、作業性が悪いという問題がある。特にこの状態でさらにペダル軸をペダル受具に挿抜するのは非常に作業性が悪く、別の人の手助けが必要になることもある。またペダルを取外した状態では抜止係止具は遊動することになり、走行中の振動により外れて紛失し易いという問題もあった。   In this case, when inserting and removing the retaining latch, it is necessary to expand the retaining ring once in the annular circumferential groove, and a large force is required. For this reason, it is necessary to work by separately gripping the pedal fixing tool (case) and the retaining locking tool with the left and right hands, and there is a problem that workability is poor. In particular, in this state, it is very inconvenient to insert and remove the pedal shaft into and from the pedal holder and may require the assistance of another person. In addition, when the pedal is removed, the retaining stopper is loosened, and there is a problem that it is easily lost due to vibration during traveling.

特許文献２に記載されたものは、筒体の内側に装着した係止体をペダル軸に係合させてペダル軸を確実に保持するためには、係止体を強い力で内径方向へ押圧する必要がある。例えばこの係止体は板ばねで押圧する場合は、ペダル軸の着脱に大きな力が必要であり、作業性が悪くなる。また係止体を軸方向にスライドするリングで押圧する場合には、このリングをクランクとペダルの間に配置しなければならないからクランクとペダルとの間隔が広がるという問題が生じる。   In Patent Document 2, in order to securely hold the pedal shaft by engaging the locking body mounted on the inner side of the cylinder with the pedal shaft, the locking body is pressed in the inner diameter direction with a strong force. There is a need to. For example, when this locking body is pressed by a leaf spring, a large force is required to attach and detach the pedal shaft, and workability is deteriorated. Further, when the locking body is pressed by a ring that slides in the axial direction, this ring must be disposed between the crank and the pedal, so that there arises a problem that the distance between the crank and the pedal is widened.

この発明はこのような事情に鑑みなされたものであり、ペダルの着脱作業が簡単であり作業性が良く、部品を紛失するおそれが無く、ペダルとクランクの間隔を広げる必要もない自転車ペダルの着脱装置を提供することを目的とする。   The present invention has been made in view of such circumstances, and it is easy to attach and detach the pedal, and the operability is good, there is no risk of losing parts, and there is no need to widen the distance between the pedal and the crank. An object is to provide an apparatus.

この発明によればこの目的は、自転車のペダルクランクにペダルを着脱可能に取付けるための自転車ペダル着脱装置であって、ペダルクランクの回動端を車幅方向に貫通するペダル取付孔に外側方から螺入される筒状のペダル受筒と、ペダルクランクの回動端に装着されこの回動端の内側面との間にガイド収納部を有するケースと、ペダル受筒を貫通しこのペダル受筒から車幅方向内側に突出する突出端の外周に環状溝が形成されたペダル支持軸と、このペダル支持軸に回転自在に保持されたペダルと、前記ガイド収納部に収納されペダル支持軸の突出端に係合して保持されるガイド板と、前記のガイド収納部の内面とガイド板との間に収納されガイド板に案内されて互いに対向方向にスライド可能でありかつペダル支持軸の環状溝に係脱する略半月状の係合爪部とこの係合爪部が環状溝に係入する方向へケースから突出した操作部とを有する一対のストッパ板と、前記一対のストッパ板をその係合爪部を環状溝に係合させると共に操作部をケースから突出させる方向に付勢するばねと、を備えることを特徴とする自転車ペダル着脱装置、により達成される。   According to the present invention, an object of the present invention is to provide a bicycle pedal attachment / detachment device for detachably attaching a pedal to a bicycle pedal crank. A case having a guide housing portion between a cylindrical pedal receiving cylinder to be screwed in and a rotating end of the pedal crank and an inner surface of the rotating end, and the pedal receiving cylinder penetrating the pedal receiving cylinder A pedal support shaft in which an annular groove is formed on the outer periphery of the projecting end projecting inward in the vehicle width direction, a pedal rotatably held on the pedal support shaft, and a projection of the pedal support shaft housed in the guide housing portion A guide plate that is engaged with the end and held between the inner surface of the guide storage portion and the guide plate, is guided by the guide plate and is slidable in a mutually opposing direction, and is an annular groove of the pedal support shaft Disengage A pair of stopper plates having a substantially half-moon engaging claw portion and an operation portion protruding from the case in a direction in which the engaging claw portion engages with the annular groove, and the pair of stopper plates with the engaging claw portion. A bicycle pedal attaching / detaching device comprising: a spring that engages with the annular groove and urges the operating portion in a direction to protrude from the case.

一対のストッパ板は、互いに対向方向にスライドし、その操作部はケースから突出しているから、これらの操作部を片方の手で互いに近付けるようにスライドさせれば、半円状の係合爪部は環状溝から脱出し、ペダル支持軸は他方の手を使ってペダル受筒から抜取ることができる。すなわちペダルをペダルクランクから１人でも簡単かつ容易に取外すことができる。   The pair of stopper plates slide in opposite directions, and their operation parts protrude from the case. If these operation parts are slid so as to approach each other with one hand, a semicircular engagement claw part Escapes from the annular groove, and the pedal support shaft can be removed from the pedal receiving cylinder using the other hand. That is, the pedal can be easily and easily removed from the pedal crank by one person.

また取外したペダルをクランクに取付けるためには、一対のストッパの操作部を片手の指先で挟んで互いに近接させるようにスライドさせ、この状態でペダル支持軸をペダル受筒に挿入する。そしてペダル支持軸を最後まで押込んだ状態で指先を操作部から解放すれば、ストッパ板はばねによって復帰し、半月状の係合爪部が環状溝に係入してペダル支持軸がクランクに固定される。従って１人で容易に作業できる。   In order to attach the removed pedal to the crank, the operation parts of the pair of stoppers are slid so as to be close to each other with the fingertips of one hand, and the pedal support shaft is inserted into the pedal receiving cylinder in this state. If the fingertip is released from the operation section with the pedal support shaft pushed in to the end, the stopper plate is restored by the spring, the half-moon-shaped engagement claw is engaged with the annular groove, and the pedal support shaft is engaged with the crank. Fixed. Therefore, one person can work easily.

ストッパ板は常にケースに収納されているので、ペダル着脱時に取外すことがない。このためストッパなどを紛失するおそれもない。またストッパやガイド板などは、ペダルクランクの車体幅方向の内側にあるから、ペダルとペダルクランクの間隔を広げる必要がない。このため左右のペダル間隔が広がって乗りにくくなることもない。   Since the stopper plate is always stored in the case, it cannot be removed when the pedal is attached or detached. For this reason, there is no possibility of losing the stopper or the like. Further, since the stopper, the guide plate, and the like are inside the pedal crank in the vehicle width direction, it is not necessary to increase the distance between the pedal and the pedal crank. For this reason, the distance between the left and right pedals is not increased and it is not difficult to ride.

ペダル支持軸に形成する環状溝は断面四角の角溝とし、ここに係合するストッパ板の係合爪部の端縁がこの角溝に係合する断面四角とすれば、ペダル支持軸に軸方向に大きな衝撃が加わっても係合爪部が環状溝から意に反して脱出するおそれがなくなる。   The annular groove formed in the pedal support shaft is a square groove with a square cross section, and the end of the engaging claw portion of the stopper plate engaged therewith is a square cross section that engages with this square groove. Even if a large impact is applied in the direction, there is no possibility that the engaging claw part will unexpectedly escape from the annular groove.

ばねはガイド板と別体としてガイド板に組付けるものであってもよい。例えば板ばねを折曲してガイド板に組付けることができる。しかしガイド板を合成樹脂製としてこれにばねを一体成形することもできる。例えばストッパ板のスライド方向に対して斜めに傾いた板状のばねをガイド板に一体成形し、ストッパ板にはこのばねに摺接するカムを形成しておき、ストッパ板を押込む時にこのカムが板状のばねを倒す一方、この板状のばねの復元力によりストッパ板を復帰させるものが可能である。このようにばねをガイド板に一体成形すれば、別体のばねを用意しておく必要がなくなり、部品点数の減少と、組立性向上とが図れることになる。   The spring may be assembled to the guide plate as a separate body from the guide plate. For example, the leaf spring can be bent and assembled to the guide plate. However, the guide plate may be made of synthetic resin and the spring may be integrally formed thereon. For example, a plate-like spring inclined obliquely with respect to the sliding direction of the stopper plate is integrally formed with the guide plate, and a cam is formed on the stopper plate so as to slide on the spring. While the plate-like spring is tilted, the stopper plate can be returned by the restoring force of the plate-like spring. If the spring is integrally formed with the guide plate in this way, it is not necessary to prepare a separate spring, and the number of parts can be reduced and the assemblability can be improved.

ケースは車幅方向に分割可能とし、外側（ペダル側）のケース半体と内側のケース半体と複数のビスで固定することができる。この場合は内側のケース半体を組付ける前にガイド板、ストッパ板などを組込むことができ組立性が良くなる。外側と内側のケース半体を結合した組立体はペダルクランクにその回動端側から装着され、ペダル受筒をペダルクランクに螺着する時に内側のケース半体をこのペダル受筒とペダルクランクとで挟持して保持する。ガイド板のペダルクランクに対向する面に防塵用の薄板を密着させておけば、ケース内に侵入するほこり、砂、ゴミや泥水などがガイド板に付着しにくくなる。このためストッパ板を長期間に亘って滑らかにスライドさせることができる。   The case can be divided in the vehicle width direction, and can be fixed with a plurality of screws on the outer (half pedal) case half and the inner case half. In this case, a guide plate, a stopper plate, and the like can be assembled before assembling the inner case half, so that the assemblability is improved. The assembly in which the outer case half and the inner case half are joined is mounted on the pedal crank from its rotating end side, and when the pedal receiving cylinder is screwed onto the pedal crank, the inner case half is attached to the pedal receiving cylinder and the pedal crank. Hold by holding. If a dust-proof thin plate is brought into close contact with the surface of the guide plate facing the pedal crank, dust, sand, dust, muddy water and the like entering the case are less likely to adhere to the guide plate. For this reason, the stopper plate can be smoothly slid over a long period of time.

これらの図において、符号１０はペダルクランク、１２はこのペダルクランク１０の回動端に取付けられるペダルである。ペダルクランク１０は自転車のボトムラケット（図示せず）に保持されるクランク軸（図示せず）の左右両端に互いに１８０°の位相差を持って固定される。左右一対のペダルクランク１０にそれぞれペダル１２が取付けられ、クランク軸の回転がチェーンやベルトなどを介して後輪に伝えられる。   In these drawings, reference numeral 10 denotes a pedal crank, and 12 denotes a pedal attached to the rotating end of the pedal crank 10. The pedal crank 10 is fixed to the left and right ends of a crankshaft (not shown) held by a bicycle bottom racket (not shown) with a phase difference of 180 ° from each other. A pedal 12 is attached to each of the pair of left and right pedal cranks 10, and rotation of the crankshaft is transmitted to the rear wheels via a chain, a belt, or the like.

ここにペダル１２はペダル支持軸１４に回転自在に保持される一方、ペダル支持軸１４は、本発明に係るペダル着脱装置によってペダルクランク１０に着脱可能に取付けられる。このペダル着脱装置は、ペダルクランク１０の回動端のペダル取付孔１０ａに螺着されたペダル受筒１６と、このペダル受筒１６に挿入されたペダル支持軸１４をこのペダル受筒１６に固定するロック機構１８とを備える。   Here, the pedal 12 is rotatably held by the pedal support shaft 14, while the pedal support shaft 14 is detachably attached to the pedal crank 10 by the pedal attaching / detaching device according to the present invention. In this pedal attachment / detachment device, a pedal receiving cylinder 16 screwed into a pedal mounting hole 10 a at a rotating end of a pedal crank 10 and a pedal support shaft 14 inserted into the pedal receiving cylinder 16 are fixed to the pedal receiving cylinder 16. And a locking mechanism 18 that performs.

ペダル受筒１６は図４，５に示すように、筒部の一端にナット部を一体に形成したものであり、筒部の外周面に形成した雄ねじをペダルクランク１０に設けたペダル取付孔１０ａに車幅方向外側から螺入可能である。ペダル支持軸１４にはペダル１２の車幅方向内側に位置するフランジ部１４ａ（図１，４，５）が設けられ、このフランジ部１４ａより車幅方向内側の部分は、ペダル受筒１６に嵌合する外径を持ち、かつペダル受筒１６より長い。   As shown in FIGS. 4 and 5, the pedal receiving cylinder 16 is formed by integrally forming a nut portion at one end of the cylindrical portion, and a pedal mounting hole 10 a provided in the pedal crank 10 with a male screw formed on the outer peripheral surface of the cylindrical portion. Can be screwed in from the outside in the vehicle width direction. The pedal support shaft 14 is provided with a flange portion 14a (FIGS. 1, 4 and 5) located on the inner side in the vehicle width direction of the pedal 12, and a portion on the inner side in the vehicle width direction from the flange portion 14a is fitted in the pedal receiving cylinder 16. It has a matching outer diameter and is longer than the pedal receiving cylinder 16.

ペダル支持軸１４の内端外周、すなわちペダル受筒１６に挿入した時にペダル受筒１６から突出する部分の外周には、環状溝１４ｂが形成されている。この環状溝１４ｂは図５，７に示すように断面四角形の角溝である。   An annular groove 14 b is formed on the outer periphery of the inner end of the pedal support shaft 14, that is, on the outer periphery of the portion protruding from the pedal receiver cylinder 16 when inserted into the pedal receiver cylinder 16. The annular groove 14b is a square groove having a square cross section as shown in FIGS.

ロック機構１８は、一対のケース半体２０ａ，２０ｂからなるケース２０と、このケース２０内に収納される防塵用の薄板２２と、樹脂層のガイド板２４と、左右一対のストッパ板２６，２６とを有する。外側のケース半体２０ａは図４，５に示すように、ペダルクランク１０の先端をその内側面を除いて囲むように形成され、内側のケース半体２０ｂを被せることによりペダルクランク１０の先端を包むことになる。なお内側のケース半体２０ｂは、ガイド板２４と共に４本のビス２８により外側のケース半体２０ａに固定される。   The lock mechanism 18 includes a case 20 composed of a pair of case halves 20a, 20b, a dust-proof thin plate 22 accommodated in the case 20, a resin layer guide plate 24, and a pair of left and right stopper plates 26, 26. And have. As shown in FIGS. 4 and 5, the outer case half 20a is formed so as to surround the tip of the pedal crank 10 except for its inner surface, and the tip of the pedal crank 10 is covered by covering the inner case half 20b. I will wrap it. The inner case half 20 b is fixed to the outer case half 20 a by the four screws 28 together with the guide plate 24.

外側のケース半体２０ａの外側面中央付近にはペダル受筒１６が貫通し、ペダル受筒１６をペダルクランク１０に螺合する際にこの外側のケース半体２０ａはペダル受筒１６のナット部とペダルクランク１０との間に挟持される。   The pedal receiving cylinder 16 penetrates in the vicinity of the center of the outer surface of the outer case half 20a. When the pedal receiving cylinder 16 is screwed into the pedal crank 10, the outer case half 20a becomes the nut portion of the pedal receiving cylinder 16. And the pedal crank 10.

内側のケース半体２０ｂは図２，４などに示すように、周縁が外側へ折曲された略分銅型であり、ペダルクランク１０と略平行な側縁（ここでは左右側縁という）に内側に陥没した凹部３０，３０をもつ。この凹部３０，３０には外側のケース半体２０ａとの合せ面に向って開く切欠き３２，３２（図４，７）が形成されている。このケース半体２０ｂの内側が後記するガイド板２４やストッパ板２６を収容するガイド収納部となる。   As shown in FIGS. 2 and 4, the inner case half 20 b is a substantially weight type whose peripheral edge is bent outward, and is located on the side edge (herein, the left and right side edges) substantially parallel to the pedal crank 10. It has the recessed parts 30 and 30 depressed. The recesses 30 and 30 are formed with notches 32 and 32 (FIGS. 4 and 7) that open toward the mating surface with the outer case half 20a. The inside of the case half 20b serves as a guide storage portion for storing a guide plate 24 and a stopper plate 26 described later.

ガイド板２４は図４，６，８に示すように、内側のケース半体２０ｂの中に係入する形状に作られている。このガイド板２４には内側のケース半体２０ｂの切欠き３２，３２に連続するガイド溝３４（図４）が左右方向に横断するように形成されている。またガイド板２４は適度な弾性を有するポリプロピレンなどの樹脂で作られ、ガイド溝３４の上方および下方には略中央方向に向かって突出する４枚の板状のばね３６が一体成形されている（図４，６，８）。   As shown in FIGS. 4, 6, and 8, the guide plate 24 is formed in a shape that engages in the inner case half 20 b. The guide plate 24 is formed with a guide groove 34 (FIG. 4) continuous with the notches 32, 32 of the inner case half 20b so as to cross in the left-right direction. The guide plate 24 is made of a resin such as polypropylene having moderate elasticity, and four plate-like springs 36 are integrally formed above and below the guide groove 34 so as to protrude substantially in the center direction ( Figures 4, 6, 8).

ストッパ板２６，２６は対称に組合わされてガイド溝３４に収容され、ガイド板２４と内側のケース半体２０ｂとの間で互いに対向方向にスライド可能に装填される。ストッパ板２６の一端は内側のケース半体２０ｂの切欠き３２から外へ突出し、この突出部が操作部３８となっている。   The stopper plates 26 and 26 are combined symmetrically and accommodated in the guide groove 34, and are slidably loaded between the guide plate 24 and the inner case half 20b in the opposite direction. One end of the stopper plate 26 protrudes outward from the notch 32 of the inner case half 20 b, and this protruding portion serves as an operation portion 38.

ストッパ板２６には、ペダル支持軸１４の先端（突出端）が通る開口４０が形成され、この開口４０の一部すなわち操作部３８から遠い部分が環状溝１４ｂに係脱する略半月状の係合爪部４２となっている。またストッパ板２６の上下縁にはガイド板２４のばね３６に下側および上側から係合する鋸歯状のカム４４，４４が形成されている。この結果ばね３６とカム４４との係合により、ストッパ板２６には外側へ突出する方向の復帰習性が付与されることになる。   The stopper plate 26 is formed with an opening 40 through which the tip (protruding end) of the pedal support shaft 14 passes, and a part of the opening 40, that is, a portion far from the operation portion 38 is engaged with the annular groove 14b. A claw portion 42 is formed. In addition, saw-tooth cams 44 and 44 are formed on the upper and lower edges of the stopper plate 26 to engage with the spring 36 of the guide plate 24 from below and above. As a result, due to the engagement between the spring 36 and the cam 44, the stopper plate 26 is given a return habit in the direction of protruding outward.

薄板２２は図４，５に示すように、ガイド板２４のペダルクランクしに対向する面に密着し、ガイド板２４の周囲に塵や砂、泥水が侵入するのを防ぐ。すなわちケース２０とペダルクランク１０との間隙からケース２０内に塵や泥水などが侵入しても、この薄板２２がストッパ板２６の摺動性を悪くすることがなくなる。なお外側のケース半体２０ａの底には、水抜き孔４６（図４，５）が形成されている。   As shown in FIGS. 4 and 5, the thin plate 22 is in close contact with the surface of the guide plate 24 that faces the pedal crank and prevents dust, sand, and muddy water from entering the periphery of the guide plate 24. That is, even if dust or muddy water enters the case 20 through the gap between the case 20 and the pedal crank 10, the thin plate 22 does not deteriorate the slidability of the stopper plate 26. A drain hole 46 (FIGS. 4 and 5) is formed at the bottom of the outer case half 20a.

この実施例において、ストッパ板２６，２６の操作部３８，３８を片手の親指と人差し指とで挟んで互いに近付けるように押込めば、ストッパ板２６，２６のカム４４がばね３６を押し曲げながら互いに接近するようにスライドし、開口４０，４０の重なりが増大する。そして、この開口４０，４０の重なった部分にペダル支持軸１４が侵入および脱出可能になる。ペダル１２を取付ける場合には、ペダル支持軸１４をこの開口４０，４０の重なり部分に通して、操作部３８，３８を押し付ける指の力を弱める。するとストッパ板２６，２６はばね３６の復元力により押し戻され、係合爪部４２，４２がペダル支持軸１４の環状溝１４ｂに係入する。このためペダル１２はペダルクランク１０に固定される。   In this embodiment, if the operation portions 38, 38 of the stopper plates 26, 26 are pressed between the thumb and index finger of one hand so as to approach each other, the cams 44 of the stopper plates 26, 26 push and bend the spring 36 to each other. Slides closer together, increasing the overlap of openings 40, 40. The pedal support shaft 14 can enter and exit from the overlapping portion of the openings 40 and 40. When the pedal 12 is attached, the pedal support shaft 14 is passed through the overlapping portion of the openings 40, 40 to weaken the force of the finger pressing the operating portions 38, 38. Then, the stopper plates 26 and 26 are pushed back by the restoring force of the spring 36, and the engaging claws 42 and 42 are engaged with the annular groove 14 b of the pedal support shaft 14. For this reason, the pedal 12 is fixed to the pedal crank 10.

ペダル１２を取外すためには、ストッパ板２６，２６の操作部３８，３８を同時に押込む。この操作により、ストッパ板２６，２６の係合爪部４２が環状溝１４ｂから脱出すると共に、開口４０，４０の重なりが拡大してペダル支持軸１４がペダル受筒１６から抜き取り可能となる。すなわちペダル１２はロック機構１８から抜き取ることができる。   In order to remove the pedal 12, the operation portions 38, 38 of the stopper plates 26, 26 are simultaneously pushed. By this operation, the engaging claws 42 of the stopper plates 26, 26 are escaped from the annular groove 14 b, and the overlap of the openings 40, 40 is enlarged so that the pedal support shaft 14 can be removed from the pedal receiving cylinder 16. That is, the pedal 12 can be removed from the lock mechanism 18.

前記実施例１ではペダル支持軸１４を取付ける際に、ストッパ板２６，２６の操作部３８，３８を互いに接近する方向に親指と人差し指で挟むようにしていた。しかし図４，５，７，９などに示すように、ペダル支持軸１４の先端（内端）の周縁を面取りして円錐面４８あるいはテーパー面にしておくことにより、ペダル支持軸１４の固定をさらに簡単にすることができる。   In the first embodiment, when the pedal support shaft 14 is attached, the operation portions 38 and 38 of the stopper plates 26 and 26 are sandwiched between the thumb and the index finger in a direction approaching each other. However, as shown in FIGS. 4, 5, 7, and 9, the pedal support shaft 14 is fixed by chamfering the peripheral edge of the tip (inner end) of the pedal support shaft 14 into a conical surface 48 or a tapered surface. It can be further simplified.

この場合、ペダル支持軸１４をペダル受筒１６に強く押込むことにより円錐面４８でストッパ板２６，２６の係合爪部４２，４２を押し開くことができ、この状態でペダル支持軸１４をさらに押込むことによってこの押し開いた係合爪部４２，４２を環状溝１４ｂに係入させることができる。   In this case, by strongly pushing the pedal support shaft 14 into the pedal receiving cylinder 16, the engaging claws 42, 42 of the stopper plates 26, 26 can be pushed open by the conical surface 48, and the pedal support shaft 14 is moved in this state. By further pushing, the engaged claw portions 42, 42 that are pushed open can be engaged with the annular groove 14b.
