Further, an extension portion 15 is formed on the distal end portion of the main body portion 10 from one circumferential direction of the main body portion 10 toward the distal end side, and a contact portion 11 is formed on the distal end portion of the extension portion 15. . Although the shape of the abutting portion 11 is not particularly limited, in the present embodiment, the abutting portion 11 is formed in a substantially semi-cylindrical shape having an inner periphery adapted to the cylindrical portion 3 to which the pin 4 is attached and detached. The abutting portion 11 is formed so that the axis of the cylindrical portion 3 and the axes of the through holes 12 and 13 of the main body portion 10 intersect perpendicularly with the inner peripheral surface of the abutting portion 11 fitted to the outer peripheral surface of the cylindrical portion 3. Is done.

当て部11には、本体部10の貫通穴12,13の軸線と対応した位置に、ピン挿通穴16が貫通して形成されている。ピン挿通穴16は、ピン4を緩やかに通すように、ピン4よりやや大径に形成されている。   A pin insertion hole 16 is formed through the abutting portion 11 at a position corresponding to the axis of the through holes 12 and 13 of the main body portion 10. The pin insertion hole 16 is formed to have a slightly larger diameter than the pin 4 so as to allow the pin 4 to pass through gently.

第一部材7は、細長い棒状に形成されており、先端部17は先細りの円錐台状に形成されている。第一部材7には、その軸線に沿って、段付きの貫通穴18,19が形成されている。第一部材7の先端側に配置される小径穴は、押し棒9が進退可能にはめ込まれるガイド穴18とされる。このガイド穴18の先端部は、ピン4を受け入れ可能に、ピン4よりやや大径のピン受入部18aとされている。一方、第一部材7の基端側に配置される大径穴には、基端側へ開口してネジ穴19が形成されている。   The first member 7 is formed in an elongated rod shape, and the distal end portion 17 is formed in a tapered truncated cone shape. Stepped through holes 18 and 19 are formed in the first member 7 along its axis. The small-diameter hole disposed on the distal end side of the first member 7 is a guide hole 18 into which the push rod 9 is fitted so as to be able to advance and retract. The tip of the guide hole 18 is a pin receiving portion 18a having a slightly larger diameter than the pin 4 so that the pin 4 can be received. On the other hand, a screw hole 19 is formed in the large-diameter hole arranged on the base end side of the first member 7 so as to open to the base end side.

第一部材7の長手方向中央部には、径方向外側へ突出して大径部20が形成されている。この大径部20の外周面にはネジ山が形成されている。第一部材7は、その大径部20が、ベース6の本体部10のネジ穴13に進退可能にねじ込まれる。   A large-diameter portion 20 is formed at the center in the longitudinal direction of the first member 7 so as to protrude outward in the radial direction. A thread is formed on the outer peripheral surface of the large diameter portion 20. The large diameter portion 20 of the first member 7 is screwed into the screw hole 13 of the main body portion 10 of the base 6 so as to advance and retract.

ベース6の本体部10のネジ穴13に第一部材7の大径部20をねじ込んだ状態で、ベース6の本体部10には基端側からグリップ5がはめ込まれる。グリップ5は、外周部の一部を絞った円柱状とされ、軸線に沿って段付きの貫通穴21,22が形成されている。グリップ5の先端側に配置された大径穴21には、ベース6の本体部10がはめ込まれ、グリップ5と本体部10とは接着されて一体化される。この際、グリップ5の先端面はベース6のフランジ14に当てられた状態とされる。また、グリップ5の基端側に配置された小径穴22には、第一部材7が貫通される。第一部材7の大径部20は、グリップ5の小径穴22よりも大径であると共に、ベース6の本体部10の小径穴12よりも大径である。これにより、第一部材7は、グリップ5付きの本体部10からの脱落が防止される。   With the large-diameter portion 20 of the first member 7 screwed into the screw hole 13 of the main body portion 10 of the base 6, the grip 5 is fitted into the main body portion 10 of the base 6 from the base end side. The grip 5 has a cylindrical shape with a part of the outer peripheral portion narrowed, and stepped through holes 21 and 22 are formed along the axis. The main body portion 10 of the base 6 is fitted into the large-diameter hole 21 disposed on the front end side of the grip 5, and the grip 5 and the main body portion 10 are bonded and integrated. At this time, the front end surface of the grip 5 is brought into contact with the flange 14 of the base 6. Further, the first member 7 is passed through the small diameter hole 22 arranged on the proximal end side of the grip 5. The large diameter portion 20 of the first member 7 has a larger diameter than the small diameter hole 22 of the grip 5 and a larger diameter than the small diameter hole 12 of the main body portion 10 of the base 6. Thereby, the first member 7 is prevented from falling off from the main body 10 with the grip 5.

押し棒9は、細長い丸棒状であり、その直径は、部品に形成されるピン穴2a,3a(図7)よりも小径である。押し棒9の基端部は、第二部材8の先端部に固定されてもよいが、好ましくは両者を一体化せず次のように構成する。すなわち、押し棒9の基端部に、ケース23を介して出没ピン24を設けておき、この出没ピン24を第二部材8の先端部に当てて、第二部材8で押し棒9を動かすのがよい。   The push bar 9 is in the shape of an elongated round bar, and the diameter thereof is smaller than the pin holes 2a and 3a (FIG. 7) formed in the component. The proximal end portion of the push rod 9 may be fixed to the distal end portion of the second member 8, but preferably is configured as follows without integrating the both. That is, a protruding / extracting pin 24 is provided at the base end portion of the push rod 9 via the case 23, the protruding / extracting pin 24 is applied to the distal end portion of the second member 8, and the push rod 9 is moved by the second member 8. It is good.

ケース23は、先端側へ開口する第一穴25と、基端側へ開口する第二穴26とを有する略円筒状である。ケース23の第一穴25には、押し棒9の基端部がはめ込まれて固定される。一方、ケース23の第二穴26には、出没ピン24が脱落不能に保持される。第二穴26に収容されたバネ27により、出没ピン24はケース23の基端部から突出するよう付勢される。そして、この付勢力に対抗して、出没ピン24は、ケース23の側へ押し込み可能とされる。このようにして、出没ピン24は、ケース23に対し設定範囲を可動するが、この可動距離(バネ27により突出した状態からの押し込み可能長さ)は、たとえば1〜2mm、ここでは1mmに設定される。   The case 23 has a substantially cylindrical shape having a first hole 25 opened to the distal end side and a second hole 26 opened to the proximal end side. The base end portion of the push rod 9 is fitted into the first hole 25 of the case 23 and fixed. On the other hand, the retracting pin 24 is held in the second hole 26 of the case 23 so as not to fall off. The spring pin 27 accommodated in the second hole 26 is urged so as to protrude from the base end portion of the case 23. The intruding pin 24 can be pushed into the case 23 against the urging force. In this way, the in / out pin 24 is movable within a set range with respect to the case 23, but this movable distance (length that can be pushed in from the state of protruding by the spring 27) is set to, for example, 1 to 2 mm, here 1 mm. Is done.

ケース23を介して出没ピン24が設けられた押し棒9は、先端側を第一部材7のガイド穴18に進退可能に差し込まれる。また、基端側のケース23や出没ピン24は、第一部材7の大径穴19内に配置される。   The push rod 9 provided with the retracting pin 24 is inserted into the guide hole 18 of the first member 7 through the case 23 so as to advance and retract. Further, the base end side case 23 and the retracting pin 24 are disposed in the large-diameter hole 19 of the first member 7.

なお、出没ピン24は、必ずしもピン状である必要はなく、要はケース23の基端部からバネ27で基端側へ付勢され、その付勢力に対抗してケース23側へ押し込み可能であれば足りる。その点で、出没ピン24を出没部ということもできる。   Note that the retracting pin 24 is not necessarily pin-shaped. In short, it is urged from the base end portion of the case 23 to the base end side by the spring 27 and can be pushed toward the case 23 side against the urging force. Anything is enough. In that respect, the in / out pin 24 can also be referred to as an in / out part.

第二部材8は、ボルト28の基端部に操作材29が設けられて構成される。操作材29は、円板状のフランジ30と、このフランジ30から先端側へ突出する円筒状のボス31とが一体形成されてなる。円筒状のボス31の中空穴32は、第一部材7の外径よりも大径に形成されている。   The second member 8 is configured by providing an operation material 29 at the base end portion of the bolt 28. The operation member 29 is formed by integrally forming a disc-shaped flange 30 and a cylindrical boss 31 protruding from the flange 30 toward the tip side. The hollow hole 32 of the cylindrical boss 31 is formed to have a larger diameter than the outer diameter of the first member 7.

操作材29には、その軸線に沿って、基端部からボルト28が通される。ボルト28の頭部は、フランジ30の基端面に形成された凹部33に収容される。また、ボス31の中空穴32の底部には、ナット34が固定され、このナット34にボルト28がねじ込まれることで、操作材29とボルト28およびナット34が一体化される。   Bolts 28 are passed through the operation member 29 from the base end along the axis. The head of the bolt 28 is accommodated in a recess 33 formed on the proximal end surface of the flange 30. Further, a nut 34 is fixed to the bottom of the hollow hole 32 of the boss 31, and the operation material 29, the bolt 28, and the nut 34 are integrated by screwing the bolt 28 into the nut 34.

以上のような構成であるから、本実施例のピン着脱工具1は、グリップ5付きのベース6に対し第一部材7が進退可能にねじ込まれ、その第一部材7の基端部に第二部材8(ボルト28)が進退可能にねじ込まれる。また、第一部材7内には、出没ピン24を基端部に設けられた押し棒9が収容されている。第一部材7に対し第二部材8をねじ込めば、第二部材8が押し棒9を先端側へ押すことができる。また、ピン着脱工具1は通常立てて用いるので、第一部材7に対する第二部材8のねじ込みを緩めれば、その分だけ押し棒9を重力により基端側へ戻すことができる。   With the configuration as described above, in the pin attaching / detaching tool 1 of this embodiment, the first member 7 is screwed into the base 6 with the grip 5 so that the first member 7 can be advanced and retracted, and the second end is inserted into the base end portion of the first member 7. The member 8 (bolt 28) is screwed so as to be able to advance and retract. Further, the first member 7 accommodates a push bar 9 having a retracting pin 24 provided at the base end. If the second member 8 is screwed into the first member 7, the second member 8 can push the push rod 9 toward the distal end side. Further, since the pin attaching / detaching tool 1 is normally used upright, if the screwing of the second member 8 with respect to the first member 7 is loosened, the push rod 9 can be returned to the proximal end side by gravity accordingly.

さらに、押し棒9の先端側への移動が阻止された状態で、第一部材7に対し第二部材8をねじ込めば、ケース23に対し出没ピン24が押し込まれることになる。その後、押し棒9の先端側への移動の阻止が解除されると、バネ27の付勢力によって、ケース23から出没ピン24が突出し、その分だけ押し棒9が先端側へ移動することになる。   Further, when the second member 8 is screwed into the first member 7 in a state where the movement of the push rod 9 toward the tip end is prevented, the retracting pin 24 is pushed into the case 23. Thereafter, when the prevention of the movement of the push rod 9 toward the distal end is released, the urging pin 24 protrudes from the case 23 by the biasing force of the spring 27, and the push rod 9 moves toward the distal end side by that amount. .

以下、本実施例のピン着脱工具1の使用例について説明する。ここでは、オートバイのブレーキレバーを交換するために、ピン4を着脱する例について説明するが、ピン着脱工具1の用途はこれに限らないことは言うまでもない。   Hereinafter, a usage example of the pin attaching / detaching tool 1 of the present embodiment will be described. Here, although the example which attaches / detaches the pin 4 in order to replace | exchange the brake lever of a motorcycle is demonstrated, it cannot be overemphasized that the use of the pin attaching / detaching tool 1 is not restricted to this.

図3は、オートバイのブレーキレバー35が取り付けられた右側ハンドルの概略図である。この図に示すように、オートバイのハンドル36にブレーキレバー35が設けられるが、ハンドル36とブレーキレバー35との離隔距離は、調整ダイヤル37にて調整可能とされる。   FIG. 3 is a schematic view of a right handle to which a motorcycle brake lever 35 is attached. As shown in this figure, a brake lever 35 is provided on a handle 36 of a motorcycle. The distance between the handle 36 and the brake lever 35 can be adjusted by an adjustment dial 37.

具体的には、ブレーキを操作するプッシュロッド38に、ブレーキレバー35の中途がねじ込まれ、プッシュロッド38の端部の軸部2に、調整ダイヤル37の筒部3がはめ込まれる。そして、そのはめ合わせ部に、径方向にピン(ここではロールピン)4が圧入される。このようにして、プッシュロッド38の端部に調整ダイヤル37が設けられる。そして、調整ダイヤル37を回すことで、ハンドル36とブレーキレバー35との離隔距離を調整可能とされる。   Specifically, the middle of the brake lever 35 is screwed into the push rod 38 that operates the brake, and the cylindrical portion 3 of the adjustment dial 37 is fitted into the shaft portion 2 at the end of the push rod 38. And the pin (here roll pin) 4 is press-fit in the fitting part to radial direction. In this way, the adjustment dial 37 is provided at the end of the push rod 38. Then, the separation distance between the handle 36 and the brake lever 35 can be adjusted by turning the adjustment dial 37.

さて、たとえばオートバイの転倒事故により、ブレーキレバー35が破損した場合など、ブレーキレバー35の交換が必要なことがある。ブレーキレバー35の交換に際しては、プッシュロッド38から調整ダイヤル37を脱着する必要があり、そのためにピン4の着脱が必要である。以下、〈調整ダイヤル37の取り外し〉と、〈調整ダイヤル37の取り付け〉とを順に説明する。   Now, for example, when the brake lever 35 is damaged due to a motorcycle accident, the brake lever 35 may need to be replaced. When the brake lever 35 is replaced, it is necessary to detach the adjustment dial 37 from the push rod 38. For this reason, the pin 4 must be attached and detached. Hereinafter, <removal of the adjustment dial 37> and <attachment of the adjustment dial 37> will be described in order.

〈調整ダイヤル37の取り外し〉
図4から図7は、本実施例のピン着脱工具1を用いて、プッシュロッド38から調整ダイヤル37を取り外す状態を時系列に示す概略図であり、一部を断面にして示している。
<Removing the adjustment dial 37>
4 to 7 are schematic views showing a state in which the adjustment dial 37 is removed from the push rod 38 using the pin attaching / detaching tool 1 of the present embodiment in time series, and a part thereof is shown in cross section.

前述したように、初期状態において、プッシュロッド38の端部には、調整ダイヤル37がピン4で固定されている。その具体的構成を説明すると、まず、プッシュロッド38の端部には、ネジが切られていない丸棒状の軸部2があり、この軸部2には、径方向に貫通してピン穴2aが形成されている。一方、調整ダイヤル37は、前記軸部2にはめられる筒部3を備え、その軸方向一端部には径方向外側へ突出してダイヤル本体39が設けられている。また、筒部3には、径方向に貫通してピン穴3aが形成されている。そして、軸部2に筒部3をはめた状態で、軸部2と筒部3の各ピン穴2a,3aの位置を揃えて、そのピン穴2a,3aにピン4が圧入されて、軸部2に筒部3が保持されている。   As described above, the adjustment dial 37 is fixed to the end of the push rod 38 with the pin 4 in the initial state. The specific configuration will be described. First, at the end of the push rod 38, there is a round bar-shaped shaft portion 2 that is not threaded, and this shaft portion 2 penetrates in the radial direction and has a pin hole 2a. Is formed. On the other hand, the adjustment dial 37 includes a cylindrical portion 3 fitted to the shaft portion 2, and a dial main body 39 is provided at one end portion in the axial direction so as to protrude radially outward. Further, a pin hole 3a is formed in the cylindrical portion 3 so as to penetrate in the radial direction. Then, with the cylindrical portion 3 fitted to the shaft portion 2, the positions of the pin holes 2a and 3a of the shaft portion 2 and the cylindrical portion 3 are aligned, and the pin 4 is press-fitted into the pin holes 2a and 3a. The cylindrical portion 3 is held by the portion 2.

さて、この状態からピン着脱工具1を用いて、ピン4を取り外すには、まず図4に示すように、当て部11の内周部上端と第一部材7の先端部との離隔距離を筒部3の外径よりも大きくした状態で、筒部3の外周面に当て部11の内周面をはめればよい。この際、当て部11のピン挿通穴16を、筒部3のピン穴3aまたはそこに通されたピン4と対応させて配置する。   In order to remove the pin 4 using the pin attaching / detaching tool 1 from this state, first, as shown in FIG. 4, the separation distance between the upper end of the inner peripheral portion of the abutting portion 11 and the distal end portion of the first member 7 is changed to a cylinder. What is necessary is just to fit the inner peripheral surface of the contact part 11 in the outer peripheral surface of the cylinder part 3 in the state made larger than the outer diameter of the part 3. FIG. At this time, the pin insertion hole 16 of the abutting portion 11 is disposed in correspondence with the pin hole 3a of the cylindrical portion 3 or the pin 4 passed therethrough.

図示例のように軸部2の軸線が水平の場合、ピン4が上下方向に沿うように軸部2の回転停止位置を調整した状態として、当て部11をフックとして筒部3に引っ掛けるだけでよい。もし、筒部3の外周面上部からピン4の端部が若干突出している場合、その突出部にピン挿通穴16を入れることで、筒部3に対する当て部11の位置決めは一層容易になされる。あるいは、筒部3の外周面下部からピン4の端部が若干凹んでいる場合、次のようにして、その凹み部に出没ピン24の作用で押し棒9の先端部を入れることで、筒部3に対する当て部11の位置決めは容易になされる。つまり、まず、当て部11と押し棒9の先端部とを筒部3の外周面に当てる一方、出没ピン24がケース23に押し込まれた状態とした後、筒部3に対しピン着脱工具1を移動させて、筒部3のピン穴3aとピン着脱工具1の押し棒9の位置を揃えるようにする。そして、両者の位置が合致すれば、出没ピン24の押し込みが解かれて、押し棒9が先端側へ移動し、押し棒9の先端部が筒部3のピン穴3aに僅かに突入される。これにより、筒部3に対する当て部11の位置決めは容易になされる。   When the axis of the shaft portion 2 is horizontal as in the illustrated example, the rotation stop position of the shaft portion 2 is adjusted so that the pin 4 extends in the vertical direction, and the hook portion 11 is simply hooked on the tube portion 3 as a hook. Good. If the end portion of the pin 4 slightly protrudes from the upper part of the outer peripheral surface of the cylindrical portion 3, the positioning of the abutting portion 11 with respect to the cylindrical portion 3 is further facilitated by inserting the pin insertion hole 16 into the protruding portion. . Alternatively, when the end portion of the pin 4 is slightly recessed from the lower part of the outer peripheral surface of the tubular portion 3, the tip portion of the push rod 9 is inserted into the recessed portion by the action of the retracting pin 24 as follows. The positioning of the abutting portion 11 with respect to the portion 3 is easily performed. That is, first, the abutting portion 11 and the tip end portion of the push rod 9 are brought into contact with the outer peripheral surface of the cylindrical portion 3, while the retracting pin 24 is pushed into the case 23, and then the pin attaching / detaching tool 1 is attached to the cylindrical portion 3. Are moved so that the positions of the pin hole 3a of the cylindrical portion 3 and the push bar 9 of the pin attaching / detaching tool 1 are aligned. Then, if the positions of the two match, the push-in / out pin 24 is released, the push rod 9 moves to the tip side, and the tip portion of the push rod 9 is slightly inserted into the pin hole 3a of the tube portion 3. . Thereby, positioning of the abutting part 11 with respect to the cylinder part 3 is made easily.

次に、図5に示すように、第一部材7の先端部が筒部3に当たるまで、ベース6に対し第一部材7をねじ込めばよい。これにより、筒部3は、ベース6の当て部11と第一部材7の先端部との間に挟み込まれる。図示例では、筒部3は、周側壁上方に当て部11が当てられ、周側壁下方に第一部材7が当てられる。   Next, as shown in FIG. 5, the first member 7 may be screwed into the base 6 until the distal end portion of the first member 7 contacts the cylindrical portion 3. Thereby, the cylinder portion 3 is sandwiched between the abutting portion 11 of the base 6 and the tip portion of the first member 7. In the example of illustration, the cylinder part 3 is applied with the contact part 11 above the peripheral side wall, and the first member 7 is applied below the peripheral side wall.

当て部11のピン挿通穴16と第一部材7のガイド穴18とは同一軸線上に配置されるので、筒部3の上部においてピン穴3aにピン挿通穴16を対応させておけば、筒部3の下部においてピン穴3aにガイド穴18が対応することになる。つまり、筒部3の径方向に形成されたピン穴3aの一端部(図示例では下端部)に、第一部材7のガイド穴18が対応され、他端部(図示例では上端部)に、当て部11のピン挿通穴16が対応される。   Since the pin insertion hole 16 of the abutting portion 11 and the guide hole 18 of the first member 7 are arranged on the same axis, if the pin insertion hole 16 is made to correspond to the pin hole 3a in the upper portion of the cylinder portion 3, the tube The guide hole 18 corresponds to the pin hole 3a in the lower part of the portion 3. That is, the guide hole 18 of the first member 7 corresponds to one end portion (lower end portion in the illustrated example) of the pin hole 3a formed in the radial direction of the cylindrical portion 3, and the other end portion (upper end portion in the illustrated example). The pin insertion hole 16 of the abutting part 11 corresponds.

その状態で、図6に示すように、第一部材7に対し第二部材8をねじ込んで、第二部材8の先端部で押し棒9を押し出していけばよい。これにより、押し棒9が、軸部2および筒部3のピン穴2a,3aに挿入されつつ、ピン4をピン穴2a,3aから押し出す。筒部3からピン4が抜ける瞬間、出没ピン24のバネ力により、押し棒9が上方へ動き、ピン4が飛び出すため、ピン4の先端に指を添えておけば、ピン4が飛び出して指に当たる感触で、ピン4の抜き取りを把握することができる。   In this state, as shown in FIG. 6, the second member 8 may be screwed into the first member 7 and the push rod 9 may be pushed out at the tip of the second member 8. Thereby, the push rod 9 pushes out the pin 4 from the pin holes 2a and 3a while being inserted into the pin holes 2a and 3a of the shaft portion 2 and the cylindrical portion 3. At the moment when the pin 4 is removed from the cylindrical portion 3, the push rod 9 moves upward by the spring force of the retracting pin 24 and the pin 4 jumps out. If the finger is attached to the tip of the pin 4, the pin 4 pops out and the finger It is possible to grasp the removal of the pin 4 with the touch of hitting.

その後、図7に示すように、第一部材7に対し第二部材8を下げて、軸部2と筒部3のピン穴2a,3aから押し棒9を抜けばよい。これにより、軸部2から筒部3を取り外すことができる。   Thereafter, as shown in FIG. 7, the second member 8 may be lowered with respect to the first member 7, and the push rod 9 may be removed from the pin holes 2 a and 3 a of the shaft portion 2 and the cylindrical portion 3. Thereby, the cylinder part 3 can be removed from the shaft part 2.

なお、ブレーキレバー35を交換するには、ブレーキレバー35の支軸40(図3)を抜き外すと共に、プッシュロッド38の端面に形成された溝にマイナスドライバーの先を当てて、プッシュロッド38を回せば、ブレーキレバー35を外すことができる。そして、これと逆の動作で、新たなブレーキレバー35をプッシュロッド38に取り付けることができる。その後、以下に述べるようにして、プッシュロッド38の先端部に再び調整ダイヤル37を取り付ければよい。   In order to replace the brake lever 35, the support shaft 40 (FIG. 3) of the brake lever 35 is removed and the tip of a flathead screwdriver is applied to the groove formed on the end surface of the push rod 38 so that the push rod 38 is moved. If it is turned, the brake lever 35 can be removed. A new brake lever 35 can be attached to the push rod 38 by the reverse operation. Thereafter, as described below, the adjustment dial 37 may be attached to the tip of the push rod 38 again.

〈調整ダイヤル37の取り付け〉
図8から図11は、本実施例のピン着脱工具1を用いて、プッシュロッド38に調整ダイヤル37を取り付ける状態を時系列に示す概略図であり、一部を断面にして示している。
<Attaching the adjustment dial 37>
FIGS. 8 to 11 are schematic views showing a state in which the adjustment dial 37 is attached to the push rod 38 using the pin attaching / detaching tool 1 of this embodiment in time series, and a part thereof is shown in cross section.

まず、図8に示すように、第一部材7に対する第二部材8のねじ込みを緩めて、押し棒9の先端部をガイド穴18の先端部(つまり第一部材7の先端部)よりも沈めた状態としておき、ガイド穴18の先端部にピン4を受け入れ可能としておく。なお、ガイド穴18は、先端部のピン受入部18aのみをやや大径としておき、このピン受入部18aの底にピン4の基端部が当接した状態で、第一部材7の先端部からピン4の先端部が僅かに突出する構成としておくのがよい。   First, as shown in FIG. 8, the screwing of the second member 8 with respect to the first member 7 is loosened, and the distal end portion of the push rod 9 is submerged from the distal end portion of the guide hole 18 (that is, the distal end portion of the first member 7). The pin 4 can be received at the tip of the guide hole 18. The guide hole 18 has a slightly larger diameter only at the pin receiving portion 18a at the distal end, and the distal end portion of the first member 7 in a state where the base end portion of the pin 4 is in contact with the bottom of the pin receiving portion 18a. It is preferable that the tip of the pin 4 protrudes slightly.

いずれにせよ押し棒9の先端部を第一部材7の先端部よりも沈めた状態とし、さらに、当て部11の内周部上端と第一部材7の先端部との離隔距離を、ピン4の長さよりも短くした状態とする。そして、その状態で、当て部11のピン挿通穴16を介して、第一部材7のガイド穴18の先端部(ピン受入部18a)にピン4を落とし込めばよい。   In any case, the tip of the push rod 9 is sunk more than the tip of the first member 7, and the separation distance between the upper end of the inner peripheral portion of the abutting portion 11 and the tip of the first member 7 is determined by the pin 4. The state is shorter than the length of. In this state, the pin 4 may be dropped into the tip end portion (pin receiving portion 18a) of the guide hole 18 of the first member 7 through the pin insertion hole 16 of the abutting portion 11.

次に、図9に示すように、ベース6に対し第一部材7を進退させて、ベース6の当て部11と第一部材7の先端部とで筒部3を保持する。この際、筒部3の径方向二ヶ所のピン穴3a,3aの内、一方のピン穴3aに、第一部材7のガイド穴18の先端部を対応させ、他方のピン穴3aに、当て部11のピン挿通穴16を対応させる。予め第一部材7の先端部からピン4を少し突出させておけば、その突出部に筒部3のピン穴3aを入れることで、ピン着脱工具1に対する筒部3の保持位置は容易に決定できる。   Next, as shown in FIG. 9, the first member 7 is moved back and forth with respect to the base 6, and the cylindrical portion 3 is held by the abutting portion 11 of the base 6 and the tip portion of the first member 7. At this time, of the two pin holes 3a, 3a in the radial direction of the cylindrical portion 3, the tip end portion of the guide hole 18 of the first member 7 is made to correspond to one pin hole 3a and applied to the other pin hole 3a. The pin insertion hole 16 of the part 11 is made to correspond. If the pin 4 is slightly protruded from the front end portion of the first member 7 in advance, the holding position of the cylindrical portion 3 with respect to the pin attaching / detaching tool 1 is easily determined by inserting the pin hole 3a of the cylindrical portion 3 into the protruding portion. it can.

その後、好ましくは、第一部材7に対し第二部材8を操作して、筒部3の内周面からピン4の先端部がわずかに見える状態としてから、軸部2に筒部3をはめ込む。筒部3の内周面からピン4の先端部がわずかに突出していても、軸部2の端部はテーパ状に形成されている上、押し棒9の基端部に出没ピン24が設けられているので、その出没ピン24がケース23に押し込まれつつ、軸部2に筒部3をはめることができる。その状態で、軸部2と筒部3の各ピン穴2a,3aの位置が合致すれば、バネ27の付勢力により出没ピン24が突出することで、ピン4の先端部を軸部2のピン穴2aに入れて、軸部2と筒部3との配置を決定することができる。但し、より確実には、軸部2に筒部3をはめた後、第一部材7に対し第二部材8を少しねじ込んでから、軸部2に対し筒部3の配置を調整するのがよい。   Thereafter, preferably, the second member 8 is operated with respect to the first member 7 so that the tip portion of the pin 4 can be slightly seen from the inner peripheral surface of the cylindrical portion 3, and then the cylindrical portion 3 is fitted into the shaft portion 2. . Even if the tip end of the pin 4 slightly protrudes from the inner peripheral surface of the cylindrical portion 3, the end of the shaft portion 2 is formed in a taper shape, and a protruding pin 24 is provided at the base end of the push rod 9. Therefore, the cylindrical portion 3 can be fitted to the shaft portion 2 while the projecting pin 24 is pushed into the case 23. In this state, if the positions of the pin holes 2a and 3a of the shaft portion 2 and the cylindrical portion 3 match, the protruding and retracting pin 24 protrudes by the urging force of the spring 27, so that the tip end portion of the pin 4 is connected to the shaft portion 2. It can put in the pin hole 2a and the arrangement | positioning of the axial part 2 and the cylinder part 3 can be determined. However, more reliably, after fitting the cylindrical portion 3 to the shaft portion 2, the second member 8 is slightly screwed into the first member 7 and then the arrangement of the cylindrical portion 3 with respect to the shaft portion 2 is adjusted. Good.

いずれにしても、押し棒9の先のピン4の先端部を軸部2の外周面に当てる一方、出没ピン24がケース23に押し込まれた状態とした後、軸部2に対し筒部3を移動させて、軸部2と筒部3の各ピン穴2a,3aを揃えるようにする。この場合、軸部2と筒部3の各ピン穴2a,3aの位置が合致すれば、出没ピン24の押し込みが解かれて、押し棒9が先端側へ移動し、それにより図10に示すように、ピン4の先端部が軸部2のピン穴2aに僅かに突入される。このようにして、ピン4と軸部2のピン穴2aを、容易で確実に位置決めすることができる。   In any case, after the tip of the pin 4 at the end of the push rod 9 is brought into contact with the outer peripheral surface of the shaft portion 2, the projecting pin 24 is pushed into the case 23, and then the tube portion 3 is moved with respect to the shaft portion 2. Is moved so that the pin holes 2a and 3a of the shaft portion 2 and the cylindrical portion 3 are aligned. In this case, if the positions of the pin holes 2a and 3a of the shaft portion 2 and the cylindrical portion 3 match, the push-in / out pin 24 is released, and the push rod 9 moves to the tip side, and as shown in FIG. Thus, the tip of the pin 4 is slightly inserted into the pin hole 2 a of the shaft 2. In this way, the pin 4 and the pin hole 2a of the shaft portion 2 can be easily and reliably positioned.

その後、図11に示すように、第一部材7に対し第二部材8をねじ込んで、押し棒9でピン4を圧入していけばよい。このようにして、軸部2と筒部3の各ピン穴2a,3aに、ピン4を圧入することができる。なお、ピン穴2a,3aにピン4を圧入している際、その抵抗により、第二部材8は出没ピン24をケース23に押し込んだ状態とする。   Thereafter, as shown in FIG. 11, the second member 8 may be screwed into the first member 7 and the pin 4 may be press-fitted with the push rod 9. In this manner, the pin 4 can be press-fitted into the pin holes 2 a and 3 a of the shaft portion 2 and the cylindrical portion 3. In addition, when the pin 4 is press-fitted into the pin holes 2a and 3a, the second member 8 is in a state where the retracting pin 24 is pushed into the case 23 due to the resistance.

最後に、第一部材7に対し第二部材8を下げて、押し棒9を第一部材7内に戻すと共に、ベース6に対し第一部材7を下げて、ベース6の当て部11と第一部材7の先端部との間で挟んでいた筒部3を離せばよい。   Finally, the second member 8 is lowered with respect to the first member 7, and the push rod 9 is returned into the first member 7, and the first member 7 is lowered with respect to the base 6, so What is necessary is just to release | separate the cylinder part 3 pinched | interposed between the front-end | tip parts of the one member 7. FIG.

以上、詳述したとおり、本実施例のピン着脱工具1によれば、ベース6の当て部11と第一部材7の先端部との間で筒部3を保持しつつ、第一部材7に対し第二部材8を進退させて、押し棒9でピン4を圧入したり、押し棒9でピン4を抜いたりすることができる。従って、万力などの固定装置を別途必要とすることなく、また打撃を加えることなく、ピン4を容易で確実に着脱することができる。   As described above in detail, according to the pin attaching / detaching tool 1 of the present embodiment, the first member 7 is attached to the first member 7 while holding the cylindrical portion 3 between the abutting portion 11 of the base 6 and the tip portion of the first member 7. On the other hand, the second member 8 can be advanced and retracted, and the pin 4 can be press-fitted with the push rod 9 or the pin 4 can be removed with the push rod 9. Accordingly, the pin 4 can be easily and reliably attached and detached without requiring a separate fixing device such as a vise and without hitting.

従って、特に精密箇所や精密部品において、ピン4を着脱するのに適する。また、オートバイのブレーキレバー35の交換の際、ピン4の着脱のために打撃を加えると、その衝撃がブレーキシステムに加わり、エアかみを起こすおそれがあるが、本実施例のピン着脱工具1を用いれば、打撃を与えることなく交換できるので、そのような不都合はない。   Therefore, it is suitable for attaching and detaching the pin 4 particularly in a precision place or a precision part. In addition, when the motorcycle brake lever 35 is replaced, if an impact is applied to attach or detach the pin 4, the impact may be applied to the brake system and cause an air bite. If used, it can be exchanged without hitting, so there is no such inconvenience.

本発明のピン着脱工具1は、前記実施例の構成に限らず適宜変更可能である。特に、ベース6に対し第一部材7を進退可能とし、第一部材7に対し第二部材8を進退可能とし、第一部材7に対する第二部材8の移動により第一部材7に対し押し棒9を進退可能であれば、各部品の形状や構成は適宜に変更可能である。   The pin attaching / detaching tool 1 according to the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate. In particular, the first member 7 can be moved back and forth with respect to the base 6, the second member 8 can be moved back and forth with respect to the first member 7, and the push rod with respect to the first member 7 can be moved by the movement of the second member 8 relative to the first member 7.
