Description

本発明は、走行玩具に関し、更に詳しくは、フライホイールを用いた自走式走行玩具に関する。 The present invention relates to a traveling toy, and more particularly to a self-propelled traveling toy using a flywheel.

従来、フライホイールを用いた小型の走行玩具は、前方に押すときにのみ駆動輪を走行面に擦付けるという動作を繰り返して、フライホイールの回転速度を増速させることによりフライホイールに回転力を蓄積させ、フライホイールが回転しているときに走行玩具を走行面に載置して車体から手を離すことで、フライホイールの回転が歯車列により駆動輪に伝達されて自走することが可能とされるものであった。 Conventionally, a small traveling toy using a flywheel repeats the operation of rubbing the driving wheel against the traveling surface only when pushing forward, and the rotational speed of the flywheel is increased by increasing the rotational speed of the flywheel. By accumulating and placing the traveling toy on the running surface while the flywheel is rotating and releasing the hand from the vehicle body, the rotation of the flywheel is transmitted to the drive wheels by the gear train and can be self-propelled It was supposed to be.

しかしながら、このような走行玩具を高速回転させるための操作は、フライホイールを増速させるために繰返し走行面に走行玩具を擦付ける必要があり、駆動輪を走行面に擦付ける毎に、そのときのフライホイールの回転速度に対応した速度で車体を前方へ押し出す必要があるため、子供や初心者には困難な操作であるといった問題点があった。 However, such an operation for rotating the traveling toy at high speed requires that the traveling toy be repeatedly rubbed against the traveling surface in order to increase the speed of the flywheel, and every time the driving wheel is rubbed against the traveling surface, Because it is necessary to push the vehicle body forward at a speed corresponding to the rotational speed of the flywheel, there is a problem that it is difficult for children and beginners.

そこで、例えば、実公昭３８−２３５６３号公報（特許文献１）では、車体を取付ける底板上に支枠を取付け、支枠に機枠の前端両側を軸着すると共に、後端側をコイルばねによって底板に圧接させ、駆動軸にはラチェット歯車を取付け、ラチェット歯車の側面に接して同軸上に中間軸上のピニオンに噛合わせる歯車を遊着し、該歯車の一側にラチェット歯車に噛合わせる爪を配設し、他側にクラウンギアを取付け、該クラウンギアと噛合うクラウンギアを駆動軸上において軸方向に摺動可能に楔着し、肘部を機枠に軸支されるベルクランクの一方の下端をクラウンギアのハブ上の溝に遊嵌し、他方の側端を底板上に取付けた枠杆に緩着し、中間軸の一端に取付けた歯車をフライホイール上のピニオンに噛合わせて成る走行玩具が提案されている。 Therefore, for example, in Japanese Utility Model Publication No. 38-23563 (Patent Document 1), a support frame is mounted on a bottom plate to which a vehicle body is attached, and both front end sides of the machine frame are axially attached to the support frame, and a rear end side is provided by a coil spring. A ratchet gear is attached to the drive shaft, a ratchet gear is attached to the drive shaft, a gear that is in contact with the side surface of the ratchet gear and coaxially meshes with the pinion on the intermediate shaft is loosely attached, and a claw that meshes with the ratchet gear on one side of the gear The crown gear is attached to the other side, the crown gear meshing with the crown gear is wedged so as to be slidable in the axial direction on the drive shaft, and the elbow is pivotally supported on the machine frame. One lower end is loosely fitted in the groove on the crown gear hub, the other side end is loosely attached to the frame rod attached on the bottom plate, and the gear attached to one end of the intermediate shaft meshes with the pinion on the flywheel. A running toy consisting of That.

この考案においては、車体を走行面に押付けた状態のままで走行玩具を後退させると駆動軸が空転するため、後退時に走行玩具を走行面から離す必要が無く、車体を手で押さえたまま、走行面上を前後に移動させることで、フライホイールの回転速度を増速させることができる。
実公昭３８−２３５６３号公報 In this device, when the traveling toy is moved backward while the vehicle body is pressed against the traveling surface, the drive shaft is idled.Therefore, it is not necessary to separate the traveling toy from the traveling surface at the time of backward movement. The rotational speed of the flywheel can be increased by moving the traveling surface back and forth.
Japanese Utility Model Publication No. 38-23563

特許文献１の考案は、駆動輪を走行面に押し当てた状態で当該走行玩具を前後動させるだけで、フライホイールの回転速度を増速させることができるが、互いに噛合うクラウンギアのうち一方のクラウンギアを車体に対して左右方向に移動させる必要があるために、クラウンギアを動作させるベルクランク等の動作機構が大きくなってしまうため小型化を困難にし、又、部品点数も多く組立作業も複雑となるためコストの増加を伴うといった問題点があった。 The idea of Patent Document 1 can increase the rotational speed of the flywheel by merely moving the traveling toy back and forth with the driving wheel pressed against the traveling surface. Because it is necessary to move the crown gear in the left-right direction with respect to the vehicle body, the operating mechanism such as a bell crank that operates the crown gear becomes large, making it difficult to reduce the size and increasing the number of parts. However, there is a problem that the cost increases due to the complexity.

本発明は、このような従来技術の問題点に鑑みてなされたものであり、安価にして小型且つ軽量で遊戯者が容易に取り扱うことのできる走行玩具として、駆動輪を走行面に押し当て当該走行玩具を前後動させることによりフライホイールに一定方向の回転を与え、車体から手を離すとフライホイールの回転力が歯車列により駆動輪に伝達されて遠距離まで自走可能な走行玩具を提供することを目的としている。 The present invention has been made in view of such problems of the prior art, and pushes driving wheels against a running surface as a running toy that is inexpensive, small and lightweight and can be easily handled by a player. Providing a traveling toy that is capable of self-propelling to a long distance by applying a certain direction to the flywheel by moving the traveling toy back and forth, and when the hand is released from the vehicle body, the rotational force of the flywheel is transmitted to the drive wheels by the gear train.

具体的には、左側支持板92及び中央支持板94には、制御伝達歯車3の回転軸である制御軸30を軸架する保持孔90が前後方向を長手方向とする長孔として形成されており、これにより、制御伝達歯車3は当該保持孔90に沿って前後方向に移動することができ、前方に制御伝達歯車3が移動すると当該制御伝達歯車3は駆動輪用歯車2及びフライホイール用入力歯車42の小径部43に噛合わされ、後方に制御伝達歯車3が移動すると当該制御伝達歯車3は駆動輪用歯車2にのみ噛合わされることとなる。 Specifically, in the left support plate 92 and the central support plate 94, a holding hole 90 that pivots the control shaft 30 that is the rotation shaft of the control transmission gear 3 is formed as a long hole whose longitudinal direction is the front-rear direction. Thus, the control transmission gear 3 can move in the front-rear direction along the holding hole 90, and when the control transmission gear 3 moves forward, the control transmission gear 3 is used for the drive wheel gear 2 and the flywheel. When the control transmission gear 3 is engaged with the small diameter portion 43 of the input gear 42 and moved rearward, the control transmission gear 3 is engaged only with the drive wheel gear 2.

又、この走行玩具1は、制御伝達歯車3をフライホイール用入力歯車42の小径部43に噛合うまで移動させ、当該制御伝達歯車3をフライホイール用入力歯車42の小径部43及び駆動輪用歯車2に噛合わせた拘束状態を維持可能とする制御機構5を備え、更に車体10が該制御機構5を外部から押下操作可能な操作部6として形成されているものである。 Further, the traveling toy 1 moves the control transmission gear 3 until it engages with the small diameter portion 43 of the flywheel input gear 42, and the control transmission gear 3 is used for the small diameter portion 43 of the flywheel input gear 42 and the drive wheel. A control mechanism 5 that can maintain a restrained state meshed with the gear 2 is provided, and the vehicle body 10 is further formed as an operation unit 6 that can be operated to press down the control mechanism 5 from the outside.

そして、この制御機構5は、外部からの押下操作により回動可能に左側及び中央支持板92,94に枢設される制御部材50と、外部からの操作が解除されたとき制御部材50を回動させ、回動させた状態が維持されるように当該制御部材50を付勢する弾性体である引張コイルばね52と、を有し、非玩具操作状態で制御伝達歯車3を拘束し、玩具操作状態で制御伝達歯車3の拘束を解放するものである。 The control mechanism 5 includes a control member 50 pivotally mounted on the left and center support plates 92 and 94 so as to be rotatable by a pressing operation from the outside, and a control member 50 that rotates when the operation from the outside is released. A tension coil spring 52 that is an elastic body that urges the control member 50 so that the control member 50 is maintained in a non-toy operation state. The restraint of the control transmission gear 3 is released in the operating state.

この制御部材50は、略Ｌ字状であって、肘部において左右方向に突出するように形成される支持軸を備えているものである。又、この制御部材50の下部には、制御伝達歯車3の左右幅よりも幅広の方形状の切欠きが形成されている。そして、この制御部材50は、切欠きの両端部である脚部の前面下部が制御軸30に接した状態で、肘部の支持軸が左側支持板92及び中央支持板94に枢支されているものである。 The control member 50 is substantially L-shaped and includes a support shaft formed so as to protrude in the left-right direction at the elbow portion. In addition, a rectangular notch that is wider than the left and right widths of the control transmission gear 3 is formed in the lower part of the control member 50. In the control member 50, the support shaft of the elbow is pivotally supported by the left support plate 92 and the central support plate 94 with the lower front portion of the leg, which is both ends of the notch, in contact with the control shaft 30. It is what.

又、引張コイルばね52は、上端部のフックが制御部材50の上部より後方に突出して形成される略三角形状の平板の左側面において左方に突出するように形成される軸に貫装され、下端部のフックが中央支持板94の下部後方の左側面に突出する軸に貫装されている。これにより、引張コイルばね52は、当該引張コイルばね52の弾性力によって制御部材50の前部を上昇させる方向に、下部を前方に移動させる方向に付勢して、制御部材50の下部が制御軸30を前方に押圧して制御伝達歯車3を前方に移動させて、当該制御伝達歯車3をフライホイール用入力歯車42の小径部43に噛合わせ、制御伝達歯車3と駆動輪用歯車2とフライホイール用入力歯車42との噛合い状態が維持されるように当該制御伝達歯車3を拘束することができる。 Further, the tension coil spring 52 is inserted into a shaft formed so that the hook on the upper end protrudes rearward from the upper part of the control member 50 and protrudes to the left on the left side of the substantially triangular flat plate. The hook at the lower end is penetrated by a shaft protruding from the lower left side of the central support plate 94. As a result, the tension coil spring 52 is urged in the direction in which the front part of the control member 50 is raised by the elastic force of the tension coil spring 52 in the direction in which the lower part is moved forward, and the lower part of the control member 50 is controlled. The shaft 30 is pressed forward to move the control transmission gear 3 forward, the control transmission gear 3 is meshed with the small diameter portion 43 of the flywheel input gear 42, the control transmission gear 3 and the drive wheel gear 2 The control transmission gear 3 can be restrained so that the meshing state with the flywheel input gear 42 is maintained.

そして、この走行玩具1は、図３に示すように、車台18と車体10がピン等で固定され一体と成るものである。又、車体10は、自動車を模して形成されるものであり、制御部材50の前端近傍上方において、車体10の上端内面より下方に突出するように棒状の押圧部11が垂設され、当該押圧部11の下端が制御部材50の前端近傍上面によって支持されている。したがって、車体10及び車台18は、支持板ブロック9に対して、引張コイルばね52により付勢される制御部材50を介して揺動自在に支持されている。 In this traveling toy 1, as shown in FIG. 3, the chassis 18 and the vehicle body 10 are fixed by a pin or the like and integrated. The vehicle body 10 is formed to resemble an automobile, and in the vicinity of the front end of the control member 50, a rod-like pressing portion 11 is provided so as to protrude downward from the inner surface of the upper end of the vehicle body 10, The lower end of the pressing portion 11 is supported by the upper surface near the front end of the control member 50. Therefore, the vehicle body 10 and the chassis 18 are swingably supported with respect to the support plate block 9 via the control member 50 biased by the tension coil spring 52.

又、左側及び右側支持板92,96には、前端下部において前方に突出する前側係止突起98が形成され、後端下部において後方に突出する後側係止突起99が形成されており、前側係止突起98が車台18の前下端に形成される前側凹部に挿嵌され、後側係止突起99が車台18の後下端に形成される後側凹部に遊挿されている。 Further, the left and right support plates 92, 96 are formed with a front locking projection 98 protruding forward at the lower front end and a rear locking projection 99 protruding rearward at the lower rear end. A locking projection 98 is inserted into a front recess formed at the front lower end of the chassis 18, and a rear locking projection 99 is loosely inserted into a rear recess formed at the rear lower end of the chassis 18.

この後側凹部は、後側係止突起99の縦幅に対して十分な間隙を有しており、又、車体10及び車台18が制御機構5により支持板ブロック9に対して揺動自在に支持されているため、操作部6である車体10を下方へ押圧操作すると、図４（ａ）に示すように、後側凹部の上側の側壁に後側係止突起99の上端が係止するまで、車体10の後部が下降する。したがって、車体10を押下させれば、押圧部11が制御部材50の前端近傍上面を押圧して、制御部材50を引張コイルばね52の弾性力に抗して回動させて、制御部材50の脚部によって前方に付勢されていた制御伝達歯車3の拘束が解放されることとなる。 The rear concave portion has a sufficient gap with respect to the vertical width of the rear locking projection 99, and the vehicle body 10 and the chassis 18 can swing with respect to the support plate block 9 by the control mechanism 5. When the vehicle body 10 that is the operation portion 6 is pressed downward because it is supported, the upper end of the rear side locking projection 99 is locked to the upper side wall of the rear side recess as shown in FIG. Until the rear of the vehicle body 10 is lowered. Therefore, if the vehicle body 10 is pressed, the pressing portion 11 presses the upper surface near the front end of the control member 50, and the control member 50 is rotated against the elastic force of the tension coil spring 52, so that the control member 50 The restraint of the control transmission gear 3 urged forward by the legs is released.

以下、この走行玩具1の走行手順と動作について説明する。
先ず、図４（ａ）に示したように、走行玩具1を走行面に載置して、操作部6である車体10を外部上方から引張コイルばね52の弾性力に抗して押圧して車体10を降下させた玩具操作状態として、制御機構5による制御伝達歯車3への拘束を解放する。そして、車体10を押下させた玩具操作状態のまま、図４（ｂ）に示すように、駆動輪22を走行面に擦付けながら走行玩具1を前方に移動させて駆動輪22を回転させる。 Hereinafter, the traveling procedure and operation of the traveling toy 1 will be described.
First, as shown in FIG. 4A, the traveling toy 1 is placed on the traveling surface, and the vehicle body 10 that is the operation unit 6 is pressed against the elastic force of the tension coil spring 52 from the outside. As a toy operation state in which the vehicle body 10 is lowered, the restraint on the control transmission gear 3 by the control mechanism 5 is released. Then, with the toy operation state in which the vehicle body 10 is depressed, as shown in FIG. 4B, the driving toy 1 is moved forward while rotating the driving wheel 22 while rubbing the driving wheel 22 against the running surface.

そして、走行玩具1を前方に移動させる方向に駆動輪22が回転されると、駆動軸20に固着される駆動輪用歯車2が回転し、この回転する駆動輪用歯車2が保持孔90に沿って前後方向に移動可能な状態にある制御伝達歯車3に噛合っているため、駆動輪用歯車2の回転によって制御伝達歯車3が噛み込まれることにより当該制御伝達歯車3がフライホイール用入力歯車42の小径部43と噛合う。 When the driving wheel 22 is rotated in the direction in which the traveling toy 1 is moved forward, the driving wheel gear 2 fixed to the driving shaft 20 is rotated, and the rotating driving wheel gear 2 is rotated into the holding hole 90. Since the control transmission gear 3 is engaged by the rotation of the driving wheel gear 2, the control transmission gear 3 is input to the flywheel. It meshes with the small diameter portion 43 of the gear 42.

したがって、車体10が押圧される玩具操作状態で走行玩具1を前方に移動させると、駆動輪22の回転は、図示しない伝達歯車列8、及び、図４（ｂ）に示した駆動輪用歯車2、制御伝達歯車3を介してフライホイール用入力歯車42に伝達され、大小の歯車で構成される変速歯車群4により回転速度が増速されてフライホイール7が高速で回転することとなる。 Therefore, when the traveling toy 1 is moved forward in the toy operation state in which the vehicle body 10 is pressed, the rotation of the driving wheel 22 is caused by the transmission gear train 8 (not shown) and the driving wheel gear shown in FIG. 2. It is transmitted to the flywheel input gear 42 via the control transmission gear 3, and the rotational speed is increased by the transmission gear group 4 composed of large and small gears so that the flywheel 7 rotates at high speed.

そして、図５（ａ）に示すように、フライホイール7が回転しているときに、玩具操作状態で、走行玩具1の前方移動を止めて駆動輪22を停止させ、或いは、走行玩具1を後方に移動させて駆動輪22を逆回転させると、駆動輪用歯車2が停止、或いは、逆回転することとなる。これにより、前後方向に移動可能な状態にある制御伝達歯車3がフライホイール用入力歯車42の回転によって後方へ蹴り出されて、フライホイール用入力歯車42との噛合い状態が解除される。したがって、歯車列の回転伝達が遮断され、フライホイール用歯車列が空転状態となる。 Then, as shown in FIG. 5A, when the flywheel 7 is rotating, in the toy operation state, the forward movement of the traveling toy 1 is stopped and the driving wheel 22 is stopped, or the traveling toy 1 is When the drive wheel 22 is moved backward and the drive wheel 22 is rotated in the reverse direction, the drive wheel gear 2 is stopped or rotated in the reverse direction. As a result, the control transmission gear 3 that is movable in the front-rear direction is kicked rearward by the rotation of the flywheel input gear 42, and the meshed state with the flywheel input gear 42 is released. Accordingly, the rotation transmission of the gear train is interrupted, and the flywheel gear train is in an idling state.

又、走行玩具1の前方移動の速度を減速させて、フライホイール用入力歯車42の小径部43の回転周速度よりも駆動輪用歯車2の大径部の回転周速度が遅くなった場合も同様に、制御伝達歯車3が蹴り出されて、歯車列の回転伝達が遮断されて、フライホイール用歯車列が空転状態となる。 Also, when the speed of the forward movement of the traveling toy 1 is reduced, the rotational peripheral speed of the large diameter portion of the drive wheel gear 2 is slower than the rotational peripheral speed of the small diameter portion 43 of the flywheel input gear 42. Similarly, the control transmission gear 3 is kicked out, the rotation transmission of the gear train is cut off, and the flywheel gear train is idled.

そして、車体10を押下した玩具操作状態で、再び走行玩具1を前方に移動させれば、図４（ｂ）に示したように、再度、制御伝達歯車3がフライホイール用入力歯車42に噛合って、駆動輪22の回転が回転伝達系統である歯車列を介してフライホイール7に伝達されてフライホイール7の回転速度を増速させることができる。 Then, when the traveling toy 1 is moved forward again in the toy operation state where the vehicle body 10 is pressed, the control transmission gear 3 meshes with the flywheel input gear 42 again as shown in FIG. Thus, the rotation of the drive wheel 22 is transmitted to the flywheel 7 via a gear train that is a rotation transmission system, and the rotational speed of the flywheel 7 can be increased.

そして、図５（ｂ）に示すように、フライホイール7が回転しているときに、走行玩具1から手を離すと、車体10への押圧が解除され、制御部材50が引張コイルばね52の弾性力により回動して、車体10及び車台18を上方に持ち上げると共に、制御軸30を制御部材50の下部で前方へ押圧し、制御伝達歯車3を前方に押動した移動状態となってフライホイール用入力歯車42の小径部43に当該制御伝達歯車3を噛合わせ、この噛合い状態が維持される。これにより、フライホイール7に蓄積された回転力は、回転伝達系統である歯車列を介して前輪22F及び後輪22Rに伝達されて、走行玩具1が自走することとなる。 Then, as shown in FIG. 5 (b), when the flywheel 7 is rotating, if the hand is released from the traveling toy 1, the pressure on the vehicle body 10 is released, and the control member 50 moves the tension coil spring 52. It is rotated by the elastic force to lift the vehicle body 10 and the chassis 18 upward, press the control shaft 30 forward at the lower part of the control member 50, and the control transmission gear 3 is pushed forward to become a moving state. The control transmission gear 3 is meshed with the small diameter portion 43 of the wheel input gear 42, and this meshing state is maintained. As a result, the rotational force accumulated in the flywheel 7 is transmitted to the front wheels 22F and the rear wheels 22R via a gear train that is a rotation transmission system, and the traveling toy 1 runs on its own.

尚、この走行玩具1は、図２に示したように、伝達歯車列8によって前輪22Fと後輪22Rの回転を相互に伝達可能とする四輪駆動の走行玩具1として構成したが、伝達歯車列8を設けずに、後輪22Rのみを駆動させる後輪駆動の走行玩具1としてもよく、駆動輪用歯車2を前輪22Fの駆動軸20に配設すれば、前輪22Fのみを駆動させる前輪駆動の走行玩具1として構成することもできる。 As shown in FIG. 2, the traveling toy 1 is configured as a four-wheel-driven traveling toy 1 that allows the transmission gear train 8 to transmit the rotation of the front wheels 22F and the rear wheels 22R to each other. The rear wheel driving traveling toy 1 that drives only the rear wheel 22R without providing the row 8 may be used. If the driving wheel gear 2 is disposed on the driving shaft 20 of the front wheel 22F, the front wheel that drives only the front wheel 22F is used. The driving toy 1 can also be configured.

次に本実施例で用いる走行玩具1の変形例について述べる。この走行玩具1は、図６及び図７に示すように、前述と同様に、車台18と、車台18に覆設される車体10と、車台18の左右両側板間に軸架される軸に軸支される前輪22F及び後輪22Rと、を備え、前輪22F及び後輪22Rを駆動輪22とした四輪駆動の走行玩具1として構成されるものである。 Next, a modified example of the traveling toy 1 used in this embodiment will be described.

The traveling toy 1 in the present modification has two gears as the control transmission gear 3, and includes one of the control transmission gears 3. The gear 2, the control transmission gear 3, and the transmission gear train 8 are included. The charge control transmission gear 34 can be directly meshed with the small-diameter portion 43 of the flywheel input gear 42 and the rear wheel gear 82 as the drive wheel gear 2 that rotates the drive shaft 20, and the other. The control transmission gear 32 for traveling, which is the control transmission gear 2, can transmit the rotation between the flywheel input gear 42 and the rear wheel gear 82, which is the driving wheel gear 2, via two intermediate gears 24. Is.

そして、フライホイール用歯車列は、車台18に嵌着される中空形状のギアケース44に搭載されており、このギアケース44には、後述の制御部材50が枢設されると共に、図８に示すように、フライホイール7及び変速歯車群4が、ギアケース44の左右両側板間に軸架される軸に軸支されており、変速歯車群4がフライホイール軸に固着される最終歯車72に噛合わされている。又、最後方に位置する変速歯車であるフライホイール用入力歯車42の回転軸に固着される小径部43がギアケース44の左側方において後述の走行用の制御伝達歯車32と噛合っている。 The flywheel gear train is mounted on a hollow gear case 44 fitted to the chassis 18, and a control member 50 (described later) is pivotally mounted on the gear case 44. As shown, the flywheel 7 and the transmission gear group 4 are pivotally supported on a shaft pivoted between the left and right side plates of the gear case 44, and the final gear 72 is fixed to the flywheel shaft. Is engaged. A small-diameter portion 43 fixed to the rotation shaft of the flywheel input gear 42, which is a transmission gear located at the rearmost position, meshes with a control transmission gear 32 for travel described later on the left side of the gear case 44.

そして、駆動輪用歯車2としての後輪歯車82は、図６及び図７に示すように、左側面近傍において後輪22Rの駆動軸20に固着され、２個の中間歯車24が、当該後輪歯車82の前方に配置されている。又、伝達歯車列8は、前輪22Fの駆動軸20に固着される前輪歯車80と、この前輪歯車80と中間歯車24の回転を相互に伝達可能に前輪歯車80と中間歯車24との間に配設される１個の歯車とから構成されている。 As shown in FIGS. 6 and 7, the rear wheel gear 82 as the drive wheel gear 2 is fixed to the drive shaft 20 of the rear wheel 22R in the vicinity of the left side surface, and the two intermediate gears 24 are connected to the rear wheel 22R. It is arranged in front of the ring gear 82. The transmission gear train 8 includes a front wheel gear 80 fixed to the drive shaft 20 of the front wheel 22F, and the front wheel gear 80 and the intermediate gear 24 between the front wheel gear 80 and the intermediate gear 24 so that the rotation of the front wheel gear 80 and the intermediate gear 24 can be transmitted to each other. It is comprised from the one gearwheel arrange | positioned.

そして、制御伝達歯車3としての走行用の制御伝達歯車32は、フライホイール用入力歯車42の小径部43の前方において、後述の制御部材50の左側面に垂設される軸によって軸支されることにより、フライホイール用入力歯車42の小径部43と噛合わされ、制御部材50の回動により、フライホイール用入力歯車42の小径部43に噛合った状態で中間歯車24に着脱自在とされてフライホイール用入力歯車42と後輪歯車82との回転伝達を遮断するように中間歯車24との噛合いを解除することができるものである。 The traveling control transmission gear 32 as the control transmission gear 3 is pivotally supported by a shaft that is suspended from the left side surface of the control member 50 described later, in front of the small diameter portion 43 of the flywheel input gear 42. As a result, it is meshed with the small-diameter portion 43 of the flywheel input gear 42, and is detachably attached to the intermediate gear 24 in a state of meshing with the small-diameter portion 43 of the flywheel input gear 42 by the rotation of the control member 50. The meshing with the intermediate gear 24 can be released so as to cut off the rotation transmission between the flywheel input gear 42 and the rear wheel gear 82.

又、制御伝達歯車3としてのチャージ用の制御伝達歯車34は、後述の保持部材62の上部の左側面に垂設される軸によって軸支されることにより、下端近傍が後輪歯車82に噛合わされ、後輪歯車82に噛合った状態で前上端近傍がフライホイール用入力歯車42の小径部43に着脱自在とされてフライホイール用入力歯車42と後輪歯車82との回転伝達を遮断するように小径部43との噛合いを解除することができるものである。 Further, the charge control transmission gear 34 as the control transmission gear 3 is supported by a shaft suspended on the left side surface of the upper portion of the holding member 62 described later, so that the vicinity of the lower end meshes with the rear wheel gear 82. In the state of being engaged with the rear wheel gear 82, the vicinity of the front upper end is made detachable to the small diameter portion 43 of the flywheel input gear 42 to block the rotation transmission between the flywheel input gear 42 and the rear wheel gear 82. Thus, the engagement with the small diameter portion 43 can be released.

そして、本変形例の走行玩具1は、走行用の制御伝達歯車32を中間歯車24に噛合うまで移動させ、当該走行用の制御伝達歯車32を中間歯車24及びフライホイール用入力歯車42の小径部43に噛合わせた拘束状態を維持可能とする制御機構5を備えるものである。 Then, the traveling toy 1 of the present modified example moves the traveling control transmission gear 32 until it meshes with the intermediate gear 24, and the traveling control transmission gear 32 has a small diameter of the intermediate gear 24 and the flywheel input gear 42.

The holding member 62 that is maintained in the rotated state by the rotation of the holding member 62 and the control member 50 when the operation from the outside is performed is released, and the holding member 62 in the released state is rotated. A tension coil spring 58 that is an elastic body that urges the holding member 62 so that the rotated state is maintained, and charging control as the control transmission gear 3 is provided to the holding member 62. A transmission gear 34 is held.

これにより、チャージ用の制御伝達歯車34が後輪22Rの駆動軸20を回転中心として前後方向に移動することができ、前方にチャージ用の制御伝達歯車34が移動すると当該チャージ用の制御伝達歯車34は後輪歯車82及びフライホイール用入力歯車42の小径部43に噛合わされ、後方にチャージ用の制御伝達歯車34が移動すると当該チャージ用の制御伝達歯車34は後輪歯車82にのみ噛合わされることとなる。即ち、この保持部材62と引張りコイルばね58は前実施例における保持孔90と同様に、チャージ用の制御伝達歯車34を前後方向の所定範囲において遊動可能に保持するものである。 As a result, the charge control transmission gear 34 can move in the front-rear direction around the drive shaft 20 of the rear wheel 22R, and when the charge control transmission gear 34 moves forward, the charge control transmission gear 34 34 is meshed with the rear wheel gear 82 and the small diameter portion 43 of the flywheel input gear 42, and when the charge control transmission gear 34 moves rearward, the charge control transmission gear 34 is meshed only with the rear wheel gear 82. The Rukoto. That is, the holding member 62 and the tension coil spring 58 hold the charge control transmission gear 34 so as to be freely movable in a predetermined range in the front-rear direction, like the holding hole 90 in the previous embodiment.

又、この制御部材50及び保持部材62は、車台18の前後方向と平行になるように配置される略Ｌ字状の平板であって、制御部材50は、一方が後方に延在し他方が下方に延在するようにフライホイール用入力歯車42の回転軸に軸支され、保持部材62は、一方が前方に延在し他方が上方に延在するように後輪22Rの駆動軸20に軸支されている。そして、この制御部材50と保持部材62は、制御部材50の下端部と保持部材62の前面とが係合して相互に回転力を伝達可能に近接して配置されているものである。 The control member 50 and the holding member 62 are substantially L-shaped flat plates arranged so as to be parallel to the front-rear direction of the chassis 18, and one of the control members 50 extends rearward and the other The holding member 62 is supported on the drive shaft 20 of the rear wheel 22R so that one of the holding members 62 extends forward and the other extends upward. It is pivotally supported. The control member 50 and the holding member 62 are disposed close to each other so that the lower end portion of the control member 50 and the front surface of the holding member 62 are engaged with each other so that rotational force can be transmitted to each other.

又、制御機構5の圧縮コイルばね56は、上端部が制御部材50の後部上端側面に垂設される平板である上側弾性体支持板53と、車台18の後方上端近傍の一部に覆設される平板である下側弾性体支持板54によって上下方向に圧縮可能に挟持されているものである。又、引張コイルばね58は、一端のフックが車台18の底板から上方に突出するように形成される掛止部57に貫装され、他端のフックが保持部材62の回転軸である駆動軸20の上方において、該駆動軸20と平行になるように保持部材62の右側面に垂設される掛止棒59に貫装されている。 Further, the compression coil spring 56 of the control mechanism 5 covers the upper elastic body support plate 53 that is a flat plate whose upper end portion is suspended from the rear upper end side surface of the control member 50, and a part near the rear upper end of the chassis 18. The lower elastic support plate 54, which is a flat plate, is sandwiched so as to be compressible in the vertical direction. The tension coil spring 58 is inserted into a hooking portion 57 formed so that a hook at one end protrudes upward from the bottom plate of the chassis 18, and a drive shaft whose other hook is a rotating shaft of the holding member 62. Above 20, it is penetrated by a retaining rod 59 that is suspended from the right side surface of the holding member 62 so as to be parallel to the drive shaft 20.

これにより、圧縮コイルばね56は、当該圧縮コイルばね56の弾性力によって制御部材50の後部を上昇させる方向に、前部を降下させる方向に付勢して、制御部材50の前下端がギアケース44の左側面中央に垂設されるストッパー45に係止するまで、走行用の制御伝達歯車32を降下させて、当該走行用の制御伝達歯車32を中間歯車24に噛合わせ、走行用の制御伝達歯車32と中間歯車24とフライホイール用入力歯車42の小径部43との噛合い状態が維持されるように当該走行用の制御伝達歯車32を拘束することができる。 Thereby, the compression coil spring 56 is urged in the direction in which the rear part of the control member 50 is raised by the elastic force of the compression coil spring 56 in the direction in which the front part is lowered, and the front lower end of the control member 50 is the gear case. The control transmission gear 32 for traveling is lowered until it engages with a stopper 45 suspended from the center of the left side surface of 44, and the control transmission gear 32 for traveling is meshed with the intermediate gear 24 to control for traveling. The traveling control transmission gear 32 can be restrained so that the meshing state of the transmission gear 32, the intermediate gear 24, and the small diameter portion 43 of the flywheel input gear 42 is maintained.

又、圧縮コイルばね56の弾性力により制御部材50が回動すると、制御部材50の下端部が保持部材62に係合して保持部材62の上部を後方に移動させるように保持部材62を引張コイルばね58の弾性力に抗して回動させて、チャージ用の制御伝達歯車34を歯車列から離脱させて回転伝達系統から切り離すことができる。 Further, when the control member 50 is rotated by the elastic force of the compression coil spring 56, the holding member 62 is pulled so that the lower end portion of the control member 50 is engaged with the holding member 62 and the upper portion of the holding member 62 is moved backward. The charging control transmission gear 34 can be detached from the gear train by being rotated against the elastic force of the coil spring 58 and separated from the rotation transmission system.

そして、本変形例に係る走行玩具1は、車体10が車台18の前端に貫装される車体回転軸14によって枢支され、車体10の後端である掛止爪15が車台18の後端に形成される開口部に遊挿されているものである。又、この車体10には、制御部材50の上側弾性体支持板53の上方において、車体10の上端内面より下方に突出するように平板状の押圧部11が車台18左右方向に平行となるように垂設されており、当該押圧部11の下端が制御部材50の上側弾性体支持板53の上面によって支持されている。即ち、車体10は、車台18に対して、圧縮コイルばね56により上方に付勢される制御部材50を介して揺動自在に支持されている。 The traveling toy 1 according to the present modification is pivotally supported by a vehicle body rotating shaft 14 through which the vehicle body 10 penetrates the front end of the chassis 18, and the latching claw 15 that is the rear end of the vehicle body 10 is the rear end of the chassis 18. It is loosely inserted in the opening formed in. Further, in the vehicle body 10, a flat pressing portion 11 is provided above the upper elastic body support plate 53 of the control member 50 so as to protrude downward from the inner surface of the upper end of the vehicle body 10 so as to be parallel to the left-right direction of the chassis 18. The lower end of the pressing portion 11 is supported by the upper surface of the upper elastic body support plate 53 of the control member 50. That is, the vehicle body 10 is swingably supported with respect to the chassis 18 via the control member 50 biased upward by the compression coil spring 56.

したがって、車体10は前実施例と同様に操作部6としての機能を担い、当該車体10を下方へ押圧すると、図９（ａ）に示すように、押圧部11により押圧され回動する制御部材50の後部下端面が下側弾性体支持板54の上面に係止するまで、車体10が車体回転軸14を回転中心として回動し、車体10の後部が降下する。これにより、押圧部11が上側弾性体支持板53の上面を押圧して、制御部材50をフライホイール用入力歯車42の回転軸を回転中心として回動させ、制御部材50に軸支される走行用の制御伝達歯車32を上方に移動させて、当該走行用の制御伝達歯車32を歯車列から離脱させて回転伝達系統から切り離すことができる。 Accordingly, the vehicle body 10 functions as the operation unit 6 as in the previous embodiment. When the vehicle body 10 is pressed downward, as shown in FIG. 9A, the control member is rotated by being pressed by the pressing unit 11. Until the rear lower end surface of the rear portion 50 is engaged with the upper surface of the lower elastic body support plate 54, the vehicle body 10 rotates about the vehicle body rotation shaft 14 and the rear portion of the vehicle body 10 is lowered. As a result, the pressing portion 11 presses the upper surface of the upper elastic body support plate 53 to rotate the control member 50 around the rotation axis of the flywheel input gear 42, and the shaft is supported by the control member 50. The traveling control transmission gear 32 can be moved upward and the traveling control transmission gear 32 can be detached from the gear train and separated from the rotation transmission system.

更に、制御部材50を介して圧縮コイルばね56によって付勢されていた保持部材62の拘束が解放されて、保持部材62が引張コイルばね58の弾性力によって後輪22Rの駆動軸20を回転中心として回動し、チャージ用の制御伝達歯車34がフライホイール用入力歯車42の小径部43と噛合わされる。 Further, the restraint of the holding member 62 biased by the compression coil spring 56 via the control member 50 is released, and the holding member 62 rotates the drive shaft 20 of the rear wheel 22R about the center of rotation by the elastic force of the tension coil spring 58. And the charging control transmission gear 34 is meshed with the small diameter portion 43 of the flywheel input gear 42.

以下、本変形例に係る走行玩具1の走行手順と動作について説明する。
先ず、図９（ａ）に示したように、走行玩具1を走行面に載置して車体10を外部上方から圧縮コイルばね56の弾性力に抗して押圧して車体10を降下させた玩具操作状態として、走行用の制御伝達歯車32を中間歯車24から離隔させると共にチャージ用の制御伝達歯車34を後輪歯車82及びフライホイール用入力歯車42の小径部43に噛合わせた状態で、図９（ｂ）に示すように、駆動輪22を走行面に擦付けながら走行玩具1を前方に移動させて駆動輪22を回転させる。 Hereinafter, the traveling procedure and operation of the traveling toy 1 according to this modification will be described.
First, as shown in FIG. 9A, the traveling toy 1 is placed on the traveling surface, and the vehicle body 10 is pressed against the elastic force of the compression coil spring 56 from above the outside to lower the vehicle body 10. As a toy operation state, the control transmission gear 32 for traveling is separated from the intermediate gear 24 and the control transmission gear 34 for charging is engaged with the rear wheel gear 82 and the small diameter portion 43 of the flywheel input gear 42, As shown in FIG. 9B, the traveling toy 1 is moved forward while rubbing the driving wheel 22 against the traveling surface to rotate the driving wheel 22.

そして、駆動輪22が回転すると、駆動軸20に固着される後輪歯車82が回転し、この回転する後輪歯車82が、引張コイルばね58の弾性力により前方へ付勢されたチャージ用の制御伝達歯車34と噛合い、且つ、チャージ用制御伝達歯車34が駆動輪用歯車2である後輪歯車82の回転によって噛み込まれ、後輪歯車82の回転がチャージ用の制御伝達歯車34を介してフライホイール用入力歯車42の小径部43に伝達され、変速歯車群4を介してフライホイール7が高速で回転することとなる。 When the drive wheel 22 rotates, the rear wheel gear 82 fixed to the drive shaft 20 rotates, and the rotating rear wheel gear 82 is charged by the elastic force of the tension coil spring 58 for charging. The charging control transmission gear 34 is meshed with the rotation of the rear wheel gear 82, which is the driving wheel gear 2, and the rotation of the rear wheel gear 82 changes the charging control transmission gear 34. To the small diameter portion 43 of the flywheel input gear 42, and the flywheel 7 rotates at high speed via the transmission gear group 4.

尚、チャージ用の制御伝達歯車34は、後輪歯車82の回転によって噛み込まれることによってもフライホイール用入力歯車42と噛合うこととなるため、引張コイルばね58を設けずにチャージ用の制御伝達歯車34の後方移動を制限するために保持部材62を係止するストッパー等を備えたり、前実施例と同様に車体10に保持孔を設けたりすることで、チャージ用の制御伝達歯車34を前後方向に移動可能に構成してもよいが、この引張コイルばね58を設けることにより、より確実に噛合い状態を維持させることができ、フライホイール7のチャージを安定して行うことができる。又、この引張コイルばね58は、特にチャージ用の制御伝達歯車34が比較的大きい場合に有効である。 The charging control transmission gear 34 is engaged with the flywheel input gear 42 by being engaged by the rotation of the rear wheel gear 82. Therefore, the charging control transmission gear 34 is not provided with the tension coil spring 58. In order to limit the rearward movement of the transmission gear 34, a stopper or the like for locking the holding member 62 is provided, or by providing a holding hole in the vehicle body 10 as in the previous embodiment, the control transmission gear 34 for charging is provided. Although it may be configured to be movable in the front-rear direction, by providing this tension coil spring 58, the meshing state can be more reliably maintained and the flywheel 7 can be charged stably. The tension coil spring 58 is effective particularly when the charge control transmission gear 34 is relatively large.

そして、図１０（ａ）に示すように、フライホイール7が回転しているときに、玩具操作状態で、走行玩具1の前方移動を止めて駆動輪22を停止させ、或いは、走行玩具1を後方に移動させて駆動輪22を逆回転させると、後輪歯車82が停止、或いは、逆回転することとなる。これにより、チャージ用の制御伝達歯車34がフライホイール用入力歯車42の小径部43の回転によって後方へ蹴り出されて、フライホイール用入力歯車42との噛合い状態が解除される。したがって、歯車列の回転伝達が遮断され、フライホイール7、変速歯車群4、走行用の制御伝達歯車32が空転状態となる。 Then, as shown in FIG. 10A, when the flywheel 7 is rotating, in the toy operation state, the forward movement of the traveling toy 1 is stopped and the driving wheel 22 is stopped, or the traveling toy 1 is When the drive wheel 22 is rotated backward by moving backward, the rear wheel gear 82 stops or rotates reversely. As a result, the charge control transmission gear 34 is kicked rearward by the rotation of the small diameter portion 43 of the flywheel input gear 42, and the meshing state with the flywheel input gear 42 is released. Accordingly, the rotation transmission of the gear train is cut off, and the flywheel 7, the transmission gear group 4, and the traveling control transmission gear 32 are in an idling state.

又、走行玩具1の前方移動の速度を減速させて、フライホイール用入力歯車42の小径部43の回転周速度よりも後輪歯車82の回転周速度が遅くなった場合も同様に、チャージ用の制御伝達歯車34が蹴り出されて、歯車列の回転伝達が遮断される。 Similarly, when the rotational peripheral speed of the rear wheel gear 82 becomes slower than the rotational peripheral speed of the small-diameter portion 43 of the flywheel input gear 42 by reducing the speed of the forward movement of the traveling toy 1, The control transmission gear 34 is kicked out and the rotation transmission of the gear train is interrupted.

そして、車体10を押下した玩具操作状態で、再び走行玩具1を前方に移動させれば、図９（ｂ）に示したように、再度、チャージ用の制御伝達歯車34がフライホイール用入力歯車42に噛合って、駆動輪22の回転がチャージ用の制御伝達歯車34を含む回転伝達系統である歯車列を介してフライホイール7に伝達されてフライホイール7を増速させることができる。 Then, if the traveling toy 1 is moved forward again in the toy operation state in which the vehicle body 10 is pressed, as shown in FIG. 9B, the charge control transmission gear 34 again becomes the flywheel input gear. The rotation of the drive wheel 22 is transmitted to the flywheel 7 through a gear train that is a rotation transmission system including the charge control transmission gear 34, and the flywheel 7 can be accelerated.

又、図１０（ｂ）に示すように、フライホイール7が回転しているときに、走行玩具1から手を離すと、車体10への押圧が解除され、制御部材50が圧縮コイルばね56の弾性力により回動して、車体10を上方に持ち上げると共に、走行用の制御伝達歯車32を下方に移動させた移動状態となる。そして、走行用の制御伝達歯車32は、圧縮コイルばね56の弾性力により、且つ、フライホイール用入力歯車42の回転によって噛み込まれることにより、中間歯車24に噛合い、この噛合い状態が維持される。これにより、フライホイール7に蓄積された回転力は、走行用の制御伝達歯車32を含む回転伝達系統である歯車列を介して前輪22F及び後輪22Rに伝達されて、走行玩具1が自走することとなる。 Also, as shown in FIG. 10B, when the flywheel 7 is rotating, if the hand is released from the traveling toy 1, the pressure on the vehicle body 10 is released, and the control member 50 is connected to the compression coil spring 56. The vehicle is turned by the elastic force to raise the vehicle body 10 and move the traveling control transmission gear 32 downward. The traveling control transmission gear 32 is engaged with the intermediate gear 24 by the elastic force of the compression coil spring 56 and the rotation of the flywheel input gear 42, and this meshing state is maintained. Is done. As a result, the rotational force accumulated in the flywheel 7 is transmitted to the front wheels 22F and the rear wheels 22R via a gear train that is a rotation transmission system including the control transmission gear 32 for traveling, so that the traveling toy 1 is self-propelled. Will be.

尚、この走行玩具1は、図示したように、伝達歯車列8によって前輪22Fと後輪22Rの回転を相互に伝達可能とする四輪駆動の走行玩具1として構成したが、伝達歯車列8である前輪歯車80及び前輪歯車80の後方において前輪歯車80に噛合わされる歯車を設けずに、後輪22Rのみを駆動させる後輪駆動の走行玩具1としてもよく、又、前輪22Fのみを駆動させる前輪駆動の走行玩具1として構成することもできる。 The traveling toy 1 is configured as a four-wheel-driven traveling toy 1 that can transmit the rotation of the front wheel 22F and the rear wheel 22R to each other by the transmission gear train 8, as shown in the figure. A front wheel gear 80 and a rear wheel driving traveling toy 1 that drives only the rear wheel 22R without driving a gear meshed with the front wheel gear 80 behind the front wheel gear 80 may be used, or only the front wheel 22F is driven. It can also be configured as a front wheel drive traveling toy 1.

このように、フライホイール7の回転を駆動輪22に伝達する歯車列において、歯車列の回転伝達を遮断可能に所定の歯車に着脱自在に配設される制御伝達歯車3を備えることで、安価にして小型且つ軽量で、子供や初心者であっても容易に取り扱うことのできる走行玩具1として、駆動輪22を走行面に押し当て当該走行玩具1を前後動させることによりフライホイール7に一定方向の回転を与え、車体10から手を離すとフライホイール7の回転力が歯車列により駆動輪22に伝達されて遠距離まで自走可能な走行玩具1を提供することができる。 In this way, the gear train that transmits the rotation of the flywheel 7 to the drive wheel 22 is provided with the control transmission gear 3 that is detachably disposed on a predetermined gear so that the rotation transmission of the gear train can be cut off. As a traveling toy 1 that is small and lightweight and can be handled easily even by a child or a beginner, the driving wheel 22 is pressed against the traveling surface to move the traveling toy 1 back and forth in a certain direction. When the hand is released from the vehicle body 10, the rotational force of the flywheel 7 is transmitted to the drive wheels 22 by the gear train, and the traveling toy 1 capable of self-propelled to a long distance can be provided.

そして、駆動輪用歯車2とフライホイール用入力歯車42との間に１個の制御伝達歯車3を配設した部品点数を抑えたシンプルな構成とすることによりコスト低減と小型化を図ることができる。又、歯車列に変速歯車群4を組み込むことで、フライホイール7を容易に高速回転させることができ、高速回転するフライホイール7の回転力を、歯車列を介して駆動輪22に伝達させることにより、当該走行玩具1の走行距離を更に長くすることができる。 The cost can be reduced and the size can be reduced by reducing the number of parts by arranging one control transmission gear 3 between the drive wheel gear 2 and the flywheel input gear 42. it can. Also, by incorporating the transmission gear group 4 into the gear train, the flywheel 7 can be easily rotated at high speed, and the rotational force of the flywheel 7 that rotates at high speed is transmitted to the drive wheels 22 via the gear train. Thus, the traveling distance of the traveling toy 1 can be further increased.

又、２個の制御伝達歯車3としてチャージ用の制御伝達歯車34と走行用の制御伝達歯車32を配設し、フライホイール7の回転力を２個の中間歯車24を介して駆動輪22に伝達させることで、内部部品の配置の自由度を広げることが可能となり、車体10に対応した歯車列を容易に構成することもできる。更に、歯車列を平歯車で構成すれば、内部部品の配置をシンプルなものとして、容易に組立を行うことの出来る走行玩具1を提供することができる。 In addition, a charge control transmission gear 34 and a travel control transmission gear 32 are arranged as two control transmission gears 3, and the rotational force of the flywheel 7 is transmitted to the drive wheels 22 via the two intermediate gears 24. By transmitting, it becomes possible to increase the degree of freedom of arrangement of internal parts, and a gear train corresponding to the vehicle body 10 can also be easily configured. Furthermore, if the gear train is composed of spur gears, it is possible to provide a traveling toy 1 that can be easily assembled with a simple arrangement of internal components.

そして、走行玩具1に後輪軸の回転を前輪軸に伝達する伝達歯車列8を備えて当該走行玩具1を四輪駆動とした場合は、悪路走破性や登坂性能を高めることができる。 When the traveling toy 1 is provided with the transmission gear train 8 for transmitting the rotation of the rear wheel shaft to the front wheel shaft and the traveling toy 1 is driven by four wheels, it is possible to improve rough road running performance and climbing performance.

又、このように走行玩具1を形成することで、例えば、図１１に示すような、レース場を模擬した走行台100において走行玩具1を走行させるとき、一般的には走行台100とは別の平面台においてフライホイール7の回転力を蓄積させてその後走行台100の走行路101に走行玩具1を載置して走行させるが、本発明に係る走行玩具1は、走行玩具1の前後長よりも僅かに長い直線上の走行路101があれば、走行玩具1を前後動させて容易にフライホイール7を回転させることができるため、走行台100に載せた状態でフライホイール7のチャージを行って、そのまま走行させることができる。 In addition, by forming the traveling toy 1 in this way, for example, when the traveling toy 1 is caused to travel on a traveling platform 100 that simulates a racetrack, as shown in FIG. In this plane table, the rotational force of the flywheel 7 is accumulated, and then the traveling toy 1 is placed on the traveling path 101 of the traveling table 100 for traveling. If the travel path 101 on the straight line is slightly longer than the travel toy 1, the flywheel 7 can be easily rotated by moving the toy 1 back and forth. You can go and run as it is.

そして、本発明は、以上の実施例に限定されるものでなく、発明の要旨を逸脱しない範囲で自由に変更、改良が可能である。例えば、制御伝達歯車3,34は、フライホイール用入力歯車42との噛合いを解除可能とする場合に限らず、駆動輪用歯車2,82との噛合いを解除可能としてもよいし、フライホイール用入力歯車42及び駆動輪歯車2,82の両歯車に対して解除可能としてもよい。又、走行用の制御伝達歯車32についても、駆動軸20を回転させる中間歯車24との噛合いを解除可能とする場合に限らず、中間歯車24及びフライホイール用入力歯車42の両歯車に対して解除可能としてもよい。 And this invention is not limited to the above Example, A change and improvement are possible freely in the range which does not deviate from the summary of invention. For example, the control transmission gears 3 and 34 are not limited to being able to release the engagement with the flywheel input gear 42, but may be able to release the engagement with the drive wheel gears 2 and 82, It may be possible to release both the wheel input gear 42 and the drive wheel gears 2 and 82. Further, the traveling control transmission gear 32 is not limited to the case where the meshing with the intermediate gear 24 that rotates the drive shaft 20 can be released, and both the intermediate gear 24 and the flywheel input gear 42 It may be possible to release it.

又、車体10を操作部6として形成する場合に限定することなく、車体10の屋根やボンネットなどの上面部や、当該走行玩具1としての自動車におけるドア相当部などの側面部に押し込み可能な押圧ボタンを有し、車体10を操作するために車体を指で摘んだときには該押圧ボタンが押し込まれ、指を離したときは押圧ボタンが復帰状態となり、該押圧ボタンの復帰状態のときに制御部材50が制御伝達歯車3をフライホイール用入力歯車42及び駆動輪用歯車2に噛合わせるように移動させる移動状態とされるように走行玩具1を構成してもよく、これにより、車体10を押圧する代わりに、車体10と一緒にこの押圧ボタンを同時に摘んで車体10を前後動させることにより、フライホイール7を高速で回転させて当該走行玩具1を遠距離まで走行させることができる。 Further, the present invention is not limited to the case where the vehicle body 10 is formed as the operation unit 6, and can be pushed into the upper surface portion of the vehicle body 10 such as the roof or the bonnet, or the side surface portion such as the door equivalent portion of the automobile as the traveling toy 1. The button has a button, and when the vehicle body is gripped with a finger to operate the vehicle body 10, the push button is pushed in. When the finger is released, the push button is in a return state, and when the push button is in a return state, the control member The traveling toy 1 may be configured so that 50 moves the control transmission gear 3 to mesh with the flywheel input gear 42 and the drive wheel gear 2, thereby pressing the vehicle body 10. Instead, by simultaneously holding the push buttons together with the vehicle body 10 and moving the vehicle body 10 back and forth, the flywheel 7 can be rotated at a high speed so that the traveling toy 1 can travel to a long distance.
