一方、脚部24Ｌ，24Ｒ，25Ｌ，25Ｒは、それぞれ大腿部24L1，24R1，25L1，25R1、脛部24L2，24R2，25L2，25R2、足端部24L3，24R3，25L3，25R3が順次連結された構造をしている。   On the other hand, the legs 24L, 24R, 25L, 25R are sequentially connected to the thighs 24L1, 24R1, 25L1, 25R1, shins 24L2, 24R2, 25L2, 25R2, and foot ends 24L3, 24R3, 25L3, 25R3, respectively. Has a structure.

図５を参照して、左前脚部24Ｌは、その大腿部24L1が輪郭形状を同じくした外側大腿板50と内側大腿板51を備え、一対の大腿板50，51は基端部中央に形成された軸孔50ａ，51ａに前記枢軸32が貫通して軸支される。
両大腿板50，51間には枢軸32が貫通する円筒状のカラー52が介装されて所定の間隔が維持される。 Referring to FIG. 5, the left front leg portion 24L includes an outer thigh plate 50 and an inner thigh plate 51 whose thigh portion 24L1 has the same contour shape, and the pair of thigh plates 50 and 51 are formed at the center of the base end portion. The pivot 32 is pivotally supported through the shaft holes 50a and 51a.
A cylindrical collar 52 through which the pivot 32 passes is interposed between the thigh plates 50 and 51 to maintain a predetermined distance.

内側大腿板51には、軸孔51ａの下側に軸孔51ａを中心とする円弧状の円弧孔51ｂが形成されるとともに、軸孔51ａの上側に連結ピン53が右方に突設されている。
両大腿板50，51の自由端間に脛部24L2の基端部が挟まれて支軸54により貫通して軸支される。 The inner thigh plate 51 is formed with an arc-shaped arc hole 51b centered on the shaft hole 51a on the lower side of the shaft hole 51a, and a connecting pin 53 is provided on the upper side of the shaft hole 51a. Yes.
The base end portion of the shin portion 24L2 is sandwiched between the free ends of both thigh plates 50 and 51, and is pivotally supported by the support shaft 54.

両大腿板50，51間の空隙にリンクバー55が介在し、リンクバー55の先端が脛部24L2の支軸54近傍にピン56により軸支されている。
そして、外側大腿板50と一体に内側大腿板51の基端部分を左胴体板21Ｌの前部外面に沿わせて枢軸32に軸支させるとき、左胴体板21Ｌの前下側のピン40Ｌを円弧孔51ｂに貫通してリンクバー55の基端に軸支させる。
なお、内側大腿板51の右方に突出した連結ピン53は左胴体板21Ｌの長孔36Ｌを貫通して内側に突出する。 A link bar 55 is interposed in the space between the thigh plates 50 and 51, and the end of the link bar 55 is pivotally supported by a pin 56 near the support shaft 54 of the shin portion 24L2.
When the base end portion of the inner thigh plate 51 is integrally supported by the pivot 32 along the front outer surface of the left torso plate 21L integrally with the outer thigh plate 50, the front lower pin 40L of the left torso plate 21L is It penetrates the arc hole 51b and is pivotally supported on the base end of the link bar 55.
The connecting pin 53 protruding rightward of the inner thigh plate 51 passes through the long hole 36L of the left body plate 21L and protrudes inward.

したがって、枢軸32に軸支された大腿部24L1が前後に揺動すると、左胴体板21Ｌに突設されたピン40Ｌに基端が軸支されたリンクバー55が揺動し、そのリンクバー55の先端の揺動が、大腿部24L1に支軸54を介して揺動自在に連結された脛部24L2の一部にピン56を介して作用して脛部24L2を大腿部24L1に対して揺動させ、大腿部24L1に対する脛部24L2の連結角度を変化させることができる。   Therefore, when the thigh 24L1 pivotally supported by the pivot 32 swings back and forth, the link bar 55 whose base end is pivotally supported by the pin 40L protruding from the left body plate 21L swings. The swing of the tip of 55 acts on a part of the shin part 24L2 that is slidably connected to the thigh 24L1 via the support shaft 54 via the pin 56, so that the shin part 24L2 becomes the thigh 24L1. It is possible to change the connecting angle of the shin part 24L2 with respect to the thigh part 24L1 by swinging with respect to the thigh part 24L1.

脛部24L2の先端に支軸57により足端部24L3が前後に揺動自在に吊設されている。
足端部24L3にはＮ極を足裏に向けて永久磁石Ｍflが埋設されている。 A foot end 24L3 is suspended from the tip of the shin part 24L2 by a support shaft 57 so as to be swingable back and forth.
A permanent magnet Mfl is embedded in the foot end portion 24L3 with the north pole facing the sole.

図５には図示されないが、右前脚部24Ｒも上記左前脚部24Ｌと対称的で略同じ構造をしており、足端部24R3にはＮ極を足裏に向けて永久磁石Ｍfrが埋設されている。
ただし、左前脚部24Ｌの連結ピン53に相当する右前脚部24Ｒの連結ピンは、右胴体板21Ｒの前部下側の長孔36Ｒに貫通する。 Although not shown in FIG. 5, the right front leg 24R is also symmetrical with the left front leg 24L and has substantially the same structure, and a permanent magnet Mfr is embedded in the foot end 24R3 with the N pole facing the sole. ing.
However, the connecting pin of the right front leg portion 24R corresponding to the connecting pin 53 of the left front leg portion 24L penetrates the long hole 36R on the lower side of the front portion of the right body plate 21R.

次に、図５を参照して、右後脚部25Ｒについて説明するが、構造的には上記左前脚部24Ｌと同じである。
大腿部25R1は、外側大腿板60と内側大腿板61を備え、両大腿板60，61はカラー62を介装して軸孔60ａ，61ａに前記枢軸34が貫通して軸支される。 Next, the right rear leg portion 25R will be described with reference to FIG. 5, but is structurally the same as the left front leg portion 24L.
The thigh 25R1 includes an outer thigh plate 60 and an inner thigh plate 61, and both thigh plates 60, 61 are supported by the collar 62 penetrating through the shaft holes 60a, 61a through the collar 62.

内側大腿板61には、軸孔61ａの下側に円弧孔61ｂが形成されるとともに、軸孔61ａの上側に連結ピン63が右方に突設され、この連結ピン63は左胴体板21Ｌの長孔36Ｌを貫通して内側に突出する。
両大腿板60，61の自由端間に脛部25R2の基端部が挟まれて支軸64により貫通して軸支される。 The inner thigh plate 61 is formed with an arc hole 61b on the lower side of the shaft hole 61a, and a connecting pin 63 is provided on the upper side of the shaft hole 61a so as to protrude rightward. The connecting pin 63 is connected to the left body plate 21L. It protrudes inward through the long hole 36L.
The base end portion of the shin portion 25R2 is sandwiched between the free ends of both thigh plates 60 and 61, and is pivotally supported by the support shaft 64.

両大腿板60，61間の空隙に介在するリンクバー65は、基端が右胴体板21Ｒの後下側から突出し長孔37Ｒを貫通したピン41Ｒに軸支され、先端が脛部25R2の支軸64近傍にピン66により軸支されている。
脛部25R2の先端に支軸67により足端部25R3が前後に揺動自在に吊設されている。
足端部25R3にはＮ極を足裏に向けて永久磁石Ｍrrが埋設されている。 The link bar 65 interposed in the gap between the thigh plates 60 and 61 is pivotally supported by a pin 41R whose proximal end protrudes from the rear lower side of the right body plate 21R and penetrates the long hole 37R, and the distal end is supported by the shin portion 25R2. A shaft 66 is pivotally supported near the shaft 64.
A foot end portion 25R3 is suspended from the tip of the shin portion 25R2 by a support shaft 67 so as to be swingable back and forth.
A permanent magnet Mrr is embedded in the foot end portion 25R3 with the north pole facing the sole.

図５には図示されないが、左後脚部25Ｌも上記右後脚部25Ｒと対称的で略同じ構造をしており、足端部25L3にはＮ極を足裏に向けて永久磁石Ｍrlが埋設されている。
ただし、右後脚部25Ｒの連結ピン63に相当する左後脚部25Ｌの連結ピンは、左胴体板21Ｌの後部下側の長孔37Ｌに貫通する。 Although not shown in FIG. 5, the left hind leg portion 25L is also symmetrical with the right hind leg portion 25R and has substantially the same structure, and the leg end portion 25L3 has a permanent magnet Mrl with the N pole facing the sole. Buried.
However, the connecting pin of the left rear leg portion 25L corresponding to the connecting pin 63 of the right rear leg portion 25R penetrates the long hole 37L on the lower side of the rear portion of the left body plate 21L.

このように、４本の脚部24Ｌ，24Ｒ，25Ｌ，25Ｒが胴体部21に揺動自在に取り付けられるが、左前脚部24Ｌと右後脚部25Ｒが上側連動機構70により連動され、右前脚部24Ｒと左後脚部25Ｌが下側連動機構80により連動されるようになっている。   In this way, the four leg portions 24L, 24R, 25L, 25R are swingably attached to the body portion 21, but the left front leg portion 24L and the right rear leg portion 25R are interlocked by the upper interlocking mechanism 70, and the right front leg The portion 24R and the left rear leg portion 25L are interlocked by the lower interlocking mechanism 80.

図５には、上側連動機構70が図示されており、前記胴体部21における左右胴体板21Ｌ，21Ｒの連結板30に旋回アーム72が支軸71により枢着される。
旋回アーム72は、中央を支軸71により枢着されて、左右にアーム部72Ｌ，72Ｒを延出しており、左アーム部72Ｌの先端に左摺動部材73Ｌの後端がピン74Ｌにより若干の余裕をもって枢支され、右アーム部72Ｒの先端に右摺動部材73Ｒの後端がピン74Ｒにより若干の余裕をもって枢支される。 In FIG. 5, an upper interlocking mechanism 70 is shown, and a turning arm 72 is pivotally attached to a connecting plate 30 of the left and right body plates 21L, 21R in the body portion 21 by a support shaft 71.
The swivel arm 72 is pivotally mounted at the center by a support shaft 71 and extends left and right arm portions 72L and 72R. The rear end of the left sliding member 73L is slightly pinned by a pin 74L at the front end of the left arm portion 72L. It is pivotally supported with a margin, and the rear end of the right sliding member 73R is pivotally supported by the pin 74R with a slight margin at the tip of the right arm portion 72R.

左摺動部材73Ｌは、前後に長尺の長円形鉛直板73Ｌaから後方に延出部73Ｌbが延び、同延出部73Ｌbの後端が上記のように左アーム部72Ｌにピン74Ｌにより枢支され、長円形鉛直板73Ｌaにはピン孔73Ｌcとガイド長孔73Ｌdが前後に穿孔されている。   The left sliding member 73L has a rearwardly extending portion 73Lb extending from the front and rear elongated oval vertical plates 73La, and the rear end of the extending portion 73Lb is pivotally supported by the left arm portion 72L by the pin 74L as described above. In addition, a pin hole 73Lc and a guide long hole 73Ld are drilled forward and backward in the oval vertical plate 73La.

延出部73Ｌaの後端を旋回アーム72の左アーム部72Ｌの先端に枢支した左摺動部材73Ｌは、長円形鉛直板73Ｌaを左胴体板21Ｌの内面に沿わせて内側に突出したガイドピン38Ｌをガイド長孔73Ｌdに摺動自在に嵌合させ、前記長孔36Ｌを貫通して内側に突出した連結ピン53をピン孔73Ｌcに嵌入させる。
したがって、左摺動部材73Ｌは、ガイド長孔73Ｌdに嵌合したガイドピン38Ｌと長孔36Ｌを貫通した連結ピン53によって水平に保たれて前後に摺動することができる。 The left sliding member 73L, in which the rear end of the extending portion 73La is pivotally supported on the tip of the left arm portion 72L of the swivel arm 72, has a guide that protrudes inward along the inner surface of the left body plate 21L with the oval vertical plate 73La. The pin 38L is slidably fitted into the guide long hole 73Ld, and the connecting pin 53 penetrating through the long hole 36L and projecting inward is fitted into the pin hole 73Lc.
Therefore, the left sliding member 73L can be slid forward and backward while being kept horizontal by the guide pin 38L fitted in the guide long hole 73Ld and the connecting pin 53 penetrating the long hole 36L.

右摺動部材73Ｒは、支軸71に対して左摺動部材73Ｌと点対称に構成されており、長円形鉛直板73Ｒaから後方に延びた延出部73Ｒbの後端がピン74Ｒにより旋回アーム72の右アーム部72Ｒの先端に枢支され、右胴体板21Ｒの内面に沿わせて内側に突出したガイドピン39Ｒをガイド長孔73Ｒdに摺動自在に嵌合させ、前記長孔36Ｒを貫通して内側に突出した連結ピン63をピン孔73Ｒcに嵌入させる。   The right sliding member 73R is configured point-symmetrically with the left sliding member 73L with respect to the support shaft 71, and the rear end of the extending portion 73Rb extending rearward from the oval vertical plate 73Ra is a pivot arm by a pin 74R. A guide pin 39R, which is pivotally supported at the tip of the right arm portion 72R of 72 and protrudes inward along the inner surface of the right body plate 21R, is slidably fitted into the guide long hole 73Rd, and passes through the long hole 36R. Then, the connecting pin 63 protruding inward is inserted into the pin hole 73Rc.

上側連動機構70は、以上のように構成されており、左前脚部24Ｌと右後脚部25Ｒが上側連動機構70により連動するようになっている。
すなわち、左前脚部24Ｌが後方に揺動すると、連結ピン53を介して左摺動部材73Ｌを前方へ摺動し、よってピン74Ｌを介して旋回アーム72を上面視で右回りに旋回するので、右アーム部72Ｒ先端のピン74Ｒを介して右摺動部材73Ｒが後方に摺動し、よって連結ピン63を介して右後脚部25Ｒが前方に揺動する。 The upper interlocking mechanism 70 is configured as described above, and the left front leg 24L and the right rear leg 25R are interlocked by the upper interlocking mechanism 70.
That is, when the left front leg portion 24L swings backward, the left sliding member 73L slides forward via the connecting pin 53, and thus the swing arm 72 rotates clockwise via the pin 74L in top view. The right sliding member 73R slides backward via the pin 74R at the tip of the right arm portion 72R, and thus the right rear leg portion 25R swings forward via the connecting pin 63.

このように、左前脚部24Ｌが後方に揺動すると右後脚部25Ｒが前方に揺動して左前脚部24Ｌと右後脚部25Ｒは互いに閉じるように連動し、逆に左前脚部24Ｌが前方に揺動すると右後脚部25Ｒが後方に揺動して左前脚部24Ｌと右後脚部25Ｒは互いに開くように連動する。
なお、左前脚部24Ｌと右後脚部25Ｒのいずれの側からも他の側に力が作用するようになっている。 Thus, when the left front leg portion 24L swings backward, the right rear leg portion 25R swings forward, and the left front leg portion 24L and the right rear leg portion 25R are interlocked so as to close each other, and conversely the left front leg portion 24L. When the right swings forward, the right rear leg 25R swings backward, and the left front leg 24L and the right rear leg 25R are interlocked so as to open each other.
Note that force is applied to the other side from either the left front leg 24L or the right rear leg 25R.

右前脚部24Ｒと左後脚部25Ｌを連動する下側連動機構80は、上記上側連動機構70と同じ構造をしており、下側連動機構80の旋回アーム82は、連結板30の下面に共通の前記支軸71により枢着され、旋回アーム82の右端に連結された右摺動部材が右前脚部24Ｒの揺動で前後に摺動し、旋回アーム82の左端に連結された左摺動部材が左後脚部25Ｌの揺動で前後に摺動するようになっており、右前脚部24Ｒと左後脚部25Ｌが互いに閉じたり開いたりするように連動する。   The lower interlocking mechanism 80 that interlocks the right front leg 24R and the left rear leg 25L has the same structure as the upper interlocking mechanism 70, and the swivel arm 82 of the lower interlocking mechanism 80 is on the lower surface of the connecting plate 30. The right sliding member pivotally attached by the common support shaft 71 and connected to the right end of the turning arm 82 slides back and forth by the swinging of the right front leg 24R, and the left sliding connected to the left end of the turning arm 82. The moving member slides back and forth by swinging the left rear leg portion 25L, and interlocks so that the right front leg portion 24R and the left rear leg portion 25L are closed or opened.

なお、首部22は、枢軸32に枢支され、左前脚部24Ｌの揺動により概ね前後に往復動する連結ピン53により前後に揺動するようになっている。
また、尻尾部23も枢軸34に枢支され、右後脚部25Ｒの揺動により概ね前後に往復動する連結ピン63により上下に揺動するようになっている。 The neck portion 22 is pivotally supported by a pivot 32 and is swung back and forth by a connecting pin 53 that reciprocally moves back and forth substantially by swinging the left front leg portion 24L.
The tail portion 23 is also pivotally supported by the pivot 34, and is swung up and down by a connecting pin 63 that reciprocally moves back and forth substantially by swinging the right rear leg portion 25R.

The magnet reciprocating mechanism 180 is configured as a link mechanism in a case 181 in which a flat cylinder is formed by an upper plate 181u and a lower plate 181l which are vertically long and opposed to each other in the front and rear, and left and right side plates 181s and 181s. .

図２および図６，図７を参照して、上板181ｕと下板181ｌ間に中央部で枢軸183が鉛直に架設され、上板181ｕには前後に細長く延びた左ガイド孔182Ｌと右ガイド孔182Ｒが枢軸183を挟んで左右に平行に形成されている。
１対の永久磁石184，184を前後に近接して配列した４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrが、ガイド孔182Ｌ，182Ｒに案内されて前後に往復動する。 2, 6, and 7, a pivot 183 is vertically installed at the center between the upper plate 181 u and the lower plate 181 l, and a left guide hole 182 </ b> L and a right guide that are elongated in the front-rear direction on the upper plate 181 u. The hole 182R is formed parallel to the left and right with the pivot 183 interposed therebetween.
Four pairs of permanent magnets mfl, mfr, mrl, mrr in which a pair of permanent magnets 184, 184 are arranged close to each other in the front-rear direction are guided by the guide holes 182L, 182R to reciprocate back and forth.

左前永久磁石ｍflと左後永久磁石ｍrlが左ガイド孔182Ｌの前後に配設され、右前永久磁石ｍfrと右後永久磁石ｍrrが右ガイド孔182Ｒの前後に配設される。
４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrは、それぞれ１対の永久磁石184，184が互いに異なる極性の磁極を上方に向けて小判状の容器185に嵌挿されている。 The left front permanent magnet mfl and the left rear permanent magnet mrl are arranged before and after the left guide hole 182L, and the right front permanent magnet mfr and the right rear permanent magnet mrr are arranged before and after the right guide hole 182R.
The four pairs of permanent magnets mfl, mfr, mrl, and mrr are inserted into an oval container 185 with a pair of permanent magnets 184 and 184 facing the magnetic poles having different polarities upward.

左前永久磁石ｍflと右前永久磁石ｍfrは、中央寄り（後側）の永久磁石184が上方に向けてＮ極（対応する足端部24L3，24R3の永久磁石Ｍfl，Ｍfrの足裏のＮ極と同極）が磁化され、外側（前側）の永久磁石184が上方に向けてＳ極（永久磁石Ｍfl，Ｍfrの足裏のＮ極と異極）が磁化され、左後永久磁石ｍrlと右後永久磁石ｍrrは、中央寄り（後側）の永久磁石184が上方に向けてＮ極（対応する足端部25L3，25R3の永久磁石Ｍrl，Ｍrrの足裏のＮ極と同極）が磁化され、外側（前側）の永久磁石184が上方に向けてＳ極（永久磁石Ｍrl，Ｍrrの足裏のＮ極と異極）が磁化されている。   The left front permanent magnet mfl and the right front permanent magnet mfr are arranged in such a manner that the center-side (rear) permanent magnet 184 faces N-pole upward (corresponding to the permanent magnets Mfl and Mfr of the corresponding foot end portions 24L3 and 24R3) The same polarity) is magnetized, the outer (front) permanent magnet 184 is directed upward, and the S pole (the N pole different from the soles of the permanent magnets Mfl and Mfr) is magnetized, and the left rear permanent magnet mrl and the right rear In the permanent magnet mrr, the N pole (the same polarity as the N pole on the soles of the corresponding foot end portions 25L3 and 25R3) is magnetized with the permanent magnet 184 closer to the center (rear side) facing upward. The outer (front) permanent magnet 184 is directed upward, and the south pole (different from the north pole of the soles of the permanent magnets Mrl and Mrr) is magnetized.

４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrの各容器185の下方に長円形の摺動板186が上板181ｕの上面に摺動自在に接して位置し、容器185の下面の外側の永久磁石184が対応する部分より下方へ突設されたガイドピンＰfl，Ｐfr，Ｐrl，Ｐrrと中央寄りの永久磁石184が対応する部分より下方へ突設されたガイドピン188が、摺動板186を貫通し、さらにガイド孔182Ｌ，182Ｒを貫通してケース181内に突出しており、各容器185とこれと対向する摺動板186との間にスプリング187が介装されている。   An oblong sliding plate 186 is slidably positioned on the upper surface of the upper plate 181u below each of the four sets of permanent magnet pairs mfl, mfr, mrl, and mrr. Guide pins Pfl, Pfr, Prl, Prr projecting downward from the corresponding portion of the permanent magnet 184 and guide pins 188 projecting downward from the corresponding portion of the central permanent magnet 184 correspond to the sliding plate 186. Through the guide holes 182L and 182R and projecting into the case 181. A spring 187 is interposed between each container 185 and the sliding plate 186 facing the container 185.

したがって、４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrは、ガイドピンＰfl，Ｐfr，Ｐrl，Ｐrrとガイドピン188がガイド孔182Ｌ，182Ｒに沿って移動することで、姿勢を変えずにガイド孔182Ｌ，182Ｒに案内されて前後に往復動することができる。   Accordingly, the four pairs of permanent magnets mfl, mfr, mrl, and mrr are guided without changing the posture by the guide pins Pfl, Pfr, Prl, Prr and the guide pin 188 moving along the guide holes 182L and 182R. Guided by the holes 182L and 182R, it can reciprocate back and forth.

ケース181内に突出したガイドピンＰfl，Ｐfr，Ｐrl，Ｐrrには、それぞれリンクバーＬfl，Ｌfr，Ｌrl，Ｌrrが水平に揺動自在に軸支されており、一方で、枢軸183に互いに交差する２本のクロスリンクバー190，191が中央を軸支されて水平に回動自在に設けられている。
一方のクロスリンクバー190の両端が前記リンクバーＬfl，Ｌrrの各一端とピン192，192を介して連結され、他方のクロスリンクバー191の両端が前記リンクバーＬfr，Ｌrlの各一端とピン193，193を介して連結されている。 Link bars Lfl, Lfr, Lrl, and Lrr are pivotally supported by the guide pins Pfl, Pfr, Prl, and Prr protruding into the case 181 so as to be swingable horizontally, while intersecting with the pivot 183. Two cross link bars 190 and 191 are pivotally supported at the center and are horizontally rotatable.
Both ends of one cross link bar 190 are connected to one end of the link bars Lfl and Lrr via pins 192 and 192, and both ends of the other cross link bar 191 are connected to one end of the link bars Lfr and Lrl and pins 193. , 193.

したがって、左前永久磁石対ｍflと右後永久磁石対ｍrrとが、クロスリンクバー190を介して連動し、前後に移動して互いに接近したり離れたりする。
同様に、右前永久磁石対ｍfrと左後永久磁石対ｍrlとが、クロスリンクバー191を介して連動し、前後に移動して互いに接近したり離れたりする。 Therefore, the left front permanent magnet pair mfl and the right rear permanent magnet pair mrr are linked via the cross link bar 190 and move back and forth so as to approach and separate from each other.
Similarly, the right front permanent magnet pair mfr and the left rear permanent magnet pair mrl are linked via the cross link bar 191 and move back and forth to approach and separate from each other.

そして、左前永久磁石対ｍflの容器185に突設されたガイドピンＰflに後端を軸支されて前方に長尺の連接バー195が延び、同連接バー195はケース181から飛び出しており、その前端がクランク196の先端にピン197により軸支されてクランク・スライダ機構を構成している。   A long connecting bar 195 extends forward from the guide pin Pfl projecting from the container 185 of the left front permanent magnet pair mfl so that the connecting bar 195 protrudes from the case 181. The front end of the crank 196 is pivotally supported by a pin 197 to constitute a crank slider mechanism.

同様に、右前永久磁石対ｍfrの容器185に突設されたガイドピンＰfrに後端を軸支されて前方に長尺の連接バー198が延び、同連接バー198はケース181から飛び出しており、その前端がクランク199の先端にピン200により軸支されてクランク・スライダ機構を構成しいる。   Similarly, a long connecting bar 198 extends forward from the guide pin Pfr projecting from the container 185 of the right front permanent magnet pair mfr, and the connecting bar 198 protrudes from the case 181; The front end of the crank 199 is pivotally supported by a pin 200 to constitute a crank slider mechanism.

クランク196とクランク199は、互いに約９０度の角度を存して回転軸201に同軸に嵌着されている。
クランク196とクランク199の間に挟まれるようにして被動プーリ202が、回転軸201に嵌着されている。 The crank 196 and the crank 199 are fitted coaxially to the rotary shaft 201 at an angle of about 90 degrees.
A driven pulley 202 is fitted to the rotating shaft 201 so as to be sandwiched between the crank 196 and the crank 199.

そして、ケース181の下板181ｌの右前隅にモータ205が取り付けられ、モータ205の上方に突出した駆動軸205ａが下板181ｌを貫通してケース181内に飛び出しており、この飛び出した駆動軸205ａに駆動プーリ206が嵌着されている。
この駆動プーリ206と前記被動プーリ202との間に無端ベルト207が架渡される。 A motor 205 is attached to the right front corner of the lower plate 181l of the case 181. A drive shaft 205a protruding above the motor 205 passes through the lower plate 181l and protrudes into the case 181. A driving pulley 206 is fitted to the front.
An endless belt 207 is stretched between the driving pulley 206 and the driven pulley 202.

したがって、モータ205を駆動すると、無端ベルト207を回動して回転軸201がクランク196とクランク199とともに回転する。
クランク196の回転は、連接バー195を介して左前永久磁石対ｍflを前後に往復動させ、左前永久磁石対ｍflの往復動は、リンクバーＬfl，クロスリンクバー190，リンクバーＬrrを介して右後永久磁石ｍrrを連動し往復動させる。 Therefore, when the motor 205 is driven, the endless belt 207 is rotated to rotate the rotating shaft 201 together with the crank 196 and the crank 199.
The rotation of the crank 196 reciprocates the left front permanent magnet pair mfl back and forth via the connecting bar 195, and the left front permanent magnet pair mfl reciprocates right through the link bar Lfl, the cross link bar 190, and the link bar Lrr. The rear permanent magnet mrr is interlocked and reciprocated.

また、クランク199の回転は、連接バー198を介して右前永久磁石対ｍfrを前後に往復動させ、右前永久磁石対ｍfrの往復動は、リンクバーＬfr，クロスリンクバー191，リンクバーＬrlを介して左後永久磁石ｍrlを連動し往復動させる。   The rotation of the crank 199 causes the right front permanent magnet pair mfr to reciprocate back and forth via the connecting bar 198, and the right front permanent magnet pair mfr reciprocates via the link bar Lfr, the cross link bar 191 and the link bar Lrl. The left rear permanent magnet mrl is interlocked and reciprocated.

このモータ205の駆動も前記マイクロコンピュータ170により制御される。
モータ205を駆動して４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrを前後に往復動させることで、馬模型20が４本の脚部24Ｌ，24Ｒ，25Ｌ，25Ｒを揺動して走駆する様子を、図８および図９に経時的に図示し説明する。 The driving of the motor 205 is also controlled by the microcomputer 170.
By driving the motor 205 and reciprocating the four pairs of permanent magnets mfl, mfr, mrl, and mrr back and forth, the horse model 20 runs with the four legs 24L, 24R, 25L, and 25R swinging. The manner of driving will be illustrated and described over time in FIGS.

図８および図９（さらに図２）において、走行板５の下側の４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrは、上段が右側の永久磁石対ｍfr，ｍrrを示し、下段が左側の永久磁石対ｍfl，ｍrlを示し、各永久磁石184には上側の極性が表示されている。
馬模型20の４本の脚部24Ｌ，24Ｒ，25Ｌ，25Ｒの足端部24L3，24R3，25L3，25R3に埋設された永久磁石Ｍfl，Ｍfr，Ｍrl，Ｍrrは、前記のように全てＮ極を足裏に向けている。 In FIG. 8 and FIG. 9 (further FIG. 2), the lower four sets of permanent magnet pairs mfl, mfr, mrl, and mrr on the traveling plate 5 indicate the permanent magnet pairs mfr and mrr on the right side and the lower side on the left side. The permanent magnet pairs mfl and mrl are shown, and each permanent magnet 184 displays the upper polarity.
The permanent magnets Mfl, Mfr, Mrl, Mrr embedded in the leg ends 24L3, 24R3, 25L3, 25R3 of the four legs 24L, 24R, 25L, 25R of the horse model 20 all have N poles as described above. It points to the sole of the foot.

図８(1)においては、左前永久磁石対ｍflと右後永久磁石対ｍrrは互いに近づいた位置にあり、左前脚部24Ｌの永久磁石Ｍflが左前永久磁石対ｍfrのＳ極に磁化した外側（前側）の永久磁石184に走行板５を介して吸着し、同様に右後脚部25Ｒの永久磁石Ｍrrが右後永久磁石対ｍrrのＳ極に磁化した外側（後側）の永久磁石184に走行板５を介して吸着し、左前脚部24Ｌと右後脚部25Ｒの２本で馬模型20が支持され、同時に右前永久磁石対ｍfrと左後永久磁石対ｍrlは互いに離れており、その内側の永久磁石184，184のＮ極により右前脚部24Ｒと左後脚部25Ｌはその永久磁石Ｍfrと永久磁石Ｍrlが反発されて前方および後方に跳ね上げられている。   In FIG. 8 (1), the left front permanent magnet pair mfl and the right rear permanent magnet pair mrr are located close to each other, and the permanent magnet Mfl of the left front leg 24L is magnetized on the south pole of the left front permanent magnet pair mfr ( Similarly, the permanent magnet Mrr of the right rear leg 25R is attracted to the permanent magnet 184 on the front side through the traveling plate 5, and similarly to the outer (rear) permanent magnet 184 magnetized on the south pole of the right rear permanent magnet pair mrr. The horse model 20 is supported by the left front leg portion 24L and the right rear leg portion 25R while adsorbed via the traveling plate 5, and at the same time, the right front permanent magnet pair mfr and the left rear permanent magnet pair mrl are separated from each other. Due to the N poles of the inner permanent magnets 184, 184, the right front leg portion 24R and the left rear leg portion 25L are repelled forward and backward by the repulsion of the permanent magnet Mfr and the permanent magnet Mrl.

次に、モータ205の駆動によりクランク196，199が上面視で右回りに約９０度回転すると、図８(2)に示すように、左前永久磁石対ｍflと右後永久磁石対ｍrrが互いに離れていき、右前永久磁石対ｍfrと左後永久磁石対ｍrlが互いに近づくので、左前脚部24Ｌと右後脚部25Ｒは互いに開いて、限られた長さの左前脚部24Ｌの前方より上方への揺動が大きくなると、左前永久磁石Ｍflが吸着された左前永久磁石対ｍflの外側（前側）の永久磁石184から離れ、内側の同極の永久磁石184により反発されて、左前脚部24Ｌは前上方へ振り上げられ、限られた長さの右後脚部25Ｒの後方より上方への揺動が大きくなると、右後永久磁石Ｍrrが吸着された右後永久磁石対ｍrrの外側（後側）の永久磁石184から離れ、内側の同極の永久磁石184により反発されて、右後脚部25Ｒは後上方へ蹴り上げられる。   Next, when the cranks 196 and 199 are rotated about 90 degrees clockwise as viewed from above by driving the motor 205, the left front permanent magnet pair mfl and the right rear permanent magnet pair mrr are separated from each other as shown in FIG. 8 (2). As the right front permanent magnet pair mfr and the left rear permanent magnet pair mrl approach each other, the left front leg portion 24L and the right rear leg portion 25R are opened from each other, and upward from the front of the left front leg portion 24L having a limited length. When the swinging of the left front permanent magnet Mfl is increased, the left front permanent magnet Mfl is separated from the outer (front) permanent magnet 184 of the left front permanent magnet pair mfl and is repelled by the inner permanent magnet 184 so that the left front leg portion 24L When the swinging of the right rear leg portion 25R having a limited length is increased upward from the rear, the right rear permanent magnet Mrr is attracted to the right rear permanent magnet pair mrr outside (rear side). The right rear leg 25R is repelled by the inner permanent magnet 184 away from the permanent magnet 184. Is kicked back upward.

代わって右前脚部24Ｒと左後脚部25Ｌが互いに閉じてその永久磁石Ｍfrと永久磁石Ｍrlが右前永久磁石対ｍfrと左後永久磁石対ｍrlの外側の永久磁石184，184に吸着して馬模型20を支持する。   Instead, the right front leg 24R and the left rear leg 25L are closed to each other, and the permanent magnet Mfr and the permanent magnet Mrl are attracted to the permanent magnets 184 and 184 outside the right front permanent magnet pair mfr and the left rear permanent magnet pair mrl. Support the model 20.

さらに、クランク196，199が上面視で右回りに約９０度回転すると、図９(3)に示すように、左前永久磁石対ｍflと右後永久磁石対ｍrrは互いにさらに離れた後近づくようになり、右前永久磁石対ｍfrと左後永久磁石対ｍrlは益々近づき接近するので、左前脚部24Ｌと右後脚部25Ｒは互いに一度開いた後閉じ、右前脚部24Ｒと左後脚部25Ｌは右前永久磁石対ｍfrと左後永久磁石対ｍrlの外側の永久磁石184，184に吸着したままで互いにさらに閉じながら馬模型20を支持する。   Further, when the cranks 196 and 199 are rotated about 90 degrees clockwise as viewed from above, as shown in FIG. 9 (3), the left front permanent magnet pair mfl and the right rear permanent magnet pair mrr come closer to each other after being further away from each other. Since the right front permanent magnet pair mfr and the left rear permanent magnet pair mrl get closer and closer, the left front leg portion 24L and the right rear leg portion 25R are opened and closed once, and the right front leg portion 24R and the left rear leg portion 25L are The horse model 20 is supported while being further closed while being attracted to the permanent magnets 184 and 184 outside the right front permanent magnet pair mfr and the left rear permanent magnet pair mrl.

またさらに、クランク196，199が右回りに約９０度回転すると、図９(4)に示すように、左前永久磁石対ｍflと右後永久磁石対ｍrrはさらに互いに近づき接近し、右前永久磁石対ｍfrと左後永久磁石対ｍrlは互いに離れていくので、左前脚部24Ｌと右後脚部25Ｒは互いに閉じてその永久磁石Ｍflと永久磁石Ｍrrが左前永久磁石対ｍfrと右後永久磁石対ｍrrの外側の永久磁石184，184に吸着して馬模型20を支持し、右前脚部24Ｒと左後脚部25Ｌはその永久磁石Ｍfrと永久磁石Ｍrlが永久磁石Ｍfrと永久磁石Ｍrlの外側の永久磁石184，184のＳ極に吸引されながらも内側の永久磁石184，184のＮ極により反発されて上方に上げられている。   Further, when the cranks 196, 199 rotate about 90 degrees clockwise, as shown in FIG. 9 (4), the left front permanent magnet pair mfl and the right rear permanent magnet pair mrr further approach each other and approach each other. Since mfr and left rear permanent magnet pair mrl are separated from each other, left front leg 24L and right rear leg 25R are closed to each other, and permanent magnet Mfl and permanent magnet Mrr are left front permanent magnet pair mfr and right rear permanent magnet pair mrr. The outer permanent magnets 184 and 184 are attracted to support the horse model 20, and the right front leg portion 24R and the left rear leg portion 25L have permanent magnets Mfr and permanent magnets Mrl that are permanent outside the permanent magnets Mfr and permanent magnets Mrl. While attracted by the south poles of the magnets 184 and 184, they are repelled by the north poles of the inner permanent magnets 184 and 184 and raised upward.

次に、クランク196，199が右回りに約９０度回転すると、図８(1)に示す状態に戻る。
このように、モータ205の駆動によりクランク196，199が回転することで、磁石往復動機構180を介して４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrが、ガイド孔182Ｌ，182Ｒに案内されて前後に往復動し、それぞれに従動して少なくとも２本の脚部が馬模型20を常に支持するようにして４本の脚部24Ｌ，24Ｒ，25Ｌ，25Ｒを揺動する。 Next, when the cranks 196, 199 are rotated about 90 degrees clockwise, the state shown in FIG.
Thus, when the cranks 196 and 199 are rotated by driving the motor 205, the four permanent magnet pairs mfl, mfr, mrl, and mrr are guided to the guide holes 182L and 182R via the magnet reciprocating mechanism 180. Then, the four legs 24L, 24R, 25L, 25R are swung so that at least two legs always support the horse model 20 by being reciprocated back and forth.

４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrは、それぞれ前後に往復動しながら走行体160の走行により走行板５の下面に沿って移動するので、馬模型20は４本の脚部24Ｌ，24Ｒ，25Ｌ，25Ｒを揺動しながら追従して走行板５上を走駆する。   The four pairs of permanent magnets mfl, mfr, mrl, and mrr move along the lower surface of the traveling plate 5 as the traveling body 160 travels while reciprocating back and forth, so that the horse model 20 has four leg portions 24L. , 24R, 25L, 25R are followed while swinging and running on the traveling plate 5.

この馬模型20の走駆に際して、前脚部24Ｌ，24Ｒが前上方へ振り上げられ、左後脚部25Ｌ，25Ｒが後上方へ蹴り上げられる状態が形成されるので、実際の馬の走駆する脚部の動きに近い動きをさせることができ、不自然な印象を与えることがない。   When the horse model 20 is run, the front legs 24L and 24R are swung up forward and the left rear legs 25L and 25R are kicked up rearward and upward, so that the legs of the actual horse run It can be made to move close to the movement of the part, and does not give an unnatural impression.

前記したように、左前脚部24Ｌと右後脚部25Ｒは上側連動機構70により連動し、右前脚部24Ｒと左後脚部25Ｌは下側連動機構80により連動するようになっているので、前後脚部双方から脚部の揺動が促されて動きを円滑にするとともに、常に馬模型20の胴体部21が４本の脚部24Ｌ，24Ｒ，25Ｌ，25Ｒの中央の自然な位置に支えられる。   As described above, the left front leg 24L and the right rear leg 25R are interlocked by the upper interlocking mechanism 70, and the right front leg 24R and the left rear leg 25L are interlocked by the lower interlocking mechanism 80. The swinging of the legs is promoted from both the front and rear legs to make the movement smooth, and the body part 21 of the horse model 20 is always supported at the natural position in the center of the four legs 24L, 24R, 25L, 25R. It is done.

４組の永久磁石対ｍfl，ｍfr，ｍrl，ｍrrを簡単な磁石往復動機構180により往復動させることで、馬模型20の４本の脚部24Ｌ，24Ｒ，25Ｌ，25Ｒを揺動させるので、電磁石を全く使わず、よってそのための配線も不要で、構造が簡単でコストの低減を図ることができる。   By reciprocating four pairs of permanent magnets mfl, mfr, mrl, mrr by a simple magnet reciprocating mechanism 180, the four legs 24L, 24R, 25L, 25R of the horse model 20 are swung. An electromagnet is not used at all, and therefore wiring for that purpose is unnecessary, the structure is simple, and cost can be reduced.

なお、モータ205の駆動によりクランク196，199を回転して永久磁石対ｍfl，ｍfr，ｍrl，ｍrrを前後に往復動していたが、ボールねじ機構を用いて往復動させてもよい。
その際、左前永久磁石対ｍflと右後永久磁石ｍrrを連動するクロスリンクバー190および右前永久磁石対ｍfrと左後永久磁石ｍrlを連動するクロスリンクバー191を残しておくことで、２組のボールねじ機構およびモータで駆動させることができる。 Although the cranks 196 and 199 are rotated by driving the motor 205 and the permanent magnet pairs mfl, mfr, mrl, and mrr are reciprocated back and forth, they may be reciprocated using a ball screw mechanism.
At that time, by leaving the cross link bar 190 linking the left front permanent magnet pair mfl and the right rear permanent magnet mrr and the cross link bar 191 linking the right front permanent magnet pair mfr and the left rear permanent magnet mrl, two sets are left. It can be driven by a ball screw mechanism and a motor.

次に磁石往復動機構180の変形例を図１０に示し説明する。
本磁石往復動機構250は、ケース251の上板251ｕに形成された左右平行な左ガイド孔252Ｌと右ガイド孔252Ｒが、前記ケース181のガイド孔182Ｌ，182Ｒと異なり、両端が左右外側に湾曲している。
この点が異なる以外は、前記磁石往復動機構180と同じなので、同じ部材は同じ符号を用いることとする。 Next, a modification of the magnet reciprocating mechanism 180 will be described with reference to FIG.
In the magnet reciprocating mechanism 250, left and right parallel left guide holes 252L and right guide holes 252R formed on the upper plate 251u of the case 251 are curved outwardly on the left and right sides, unlike the guide holes 182L and 182R of the case 181. is doing.
Since this point is the same as the magnet reciprocating mechanism 180 except for this point, the same reference numerals are used for the same members.

すなわち、左ガイド孔252Ｌは、両端が左側に反り返るように滑らかに湾曲した前後湾曲部252Ｌf，252Ｌrを形成し、右ガイド孔252Ｒは、両端が右側に反り返るように滑らかに湾曲した前後湾曲部252Ｒf，252Ｒrを形成している。   That is, the left guide hole 252L forms the front and rear curved portions 252Lf and 252Lr that are smoothly curved so that both ends warp to the left, and the right guide hole 252R is the front and rear curved portion 252Rf that smoothly curves so that both ends warp to the right. , 252Rr.

したがって、永久磁石対ｍfl，ｍfr，ｍrl，ｍrrが嵌挿された容器185が左右のガイド孔252Ｌ，252Ｒの両端を除く直線部分にあるときは、対をなす２つの永久磁石184，184がガイド孔252Ｌ，252Ｒの直線に沿って前後に並んだ姿勢にあるが、前後端部の湾曲部252Ｌf，252Ｒf，252Ｌr，252Ｒrに至ると、前後外側の磁石184の下方に延びるガイドピンＰfl，Ｐfr，Ｐrl，Ｐrrが湾曲部252Ｌf，252Ｒf，252Ｌr，252Ｒrに案内されてガイド孔252Ｌ，252Ｒの直線から左右外側に外れる。   Therefore, when the container 185 in which the permanent magnet pair mfl, mfr, mrl, mrr is inserted is in a straight line portion excluding both ends of the left and right guide holes 252L, 252R, the pair of permanent magnets 184, 184 are guided. The guide pins Pfl, Pfr, which extend below the front and rear magnets 184 when they reach the curved portions 252Lf, 252Rf, 252Lr, 252Rr at the front and rear end portions, are in a posture aligned along the straight line of the holes 252L, 252R. Prl and Prr are guided by the curved portions 252Lf, 252Rf, 252Lr, and 252Rr and deviate from the straight line of the guide holes 252L and 252R to the left and right outside.

例えば、図１０に示す状態は、前記図８(1)に示す状態と同じであり、左前永久磁石対ｍflと右後永久磁石対ｍrrは互いに近づいたガイド孔252Ｌ，252Ｒの直線上の位置にあるが、右前永久磁石対ｍfrと左後永久磁石対ｍrlは互いに離れて、右前永久磁石対ｍfrは右ガイド孔252Ｒの前端湾曲部252Ｒfにあって前側の磁石184が右ガイド孔252Ｒの直線から右側に外れて容器185が斜めになっており、左後永久磁石対ｍrlは左ガイド孔252Ｌの後端湾曲部252Ｌrにあって後側の磁石184が左ガイド孔252Ｌの直線から左側に外れて容器185が斜めになっている。   For example, the state shown in FIG. 10 is the same as the state shown in FIG. 8 (1), and the left front permanent magnet pair mfl and the right rear permanent magnet pair mrr are positioned on the straight lines of the guide holes 252L and 252R that are close to each other. However, the right front permanent magnet pair mfr and the left rear permanent magnet pair mrl are separated from each other, the right front permanent magnet pair mfr is in the front end curved portion 252Rf of the right guide hole 252R, and the front magnet 184 is from the straight line of the right guide hole 252R. The container 185 is inclined to the right, the left rear permanent magnet pair mrl is in the rear end curved portion 252Lr of the left guide hole 252L, and the rear magnet 184 is moved to the left from the straight line of the left guide hole 252L. The container 185 is slanted.

馬模型20の左側前後の脚部24Ｌ，25Ｌは、左ガイド孔252Ｌの直線部分に沿って揺動し、右側前後の脚部24Ｒ，25Ｒは、左ガイド孔252Ｒの直線部分に沿って揺動するので、右前脚部24Ｒの永久磁石Ｍfrが右前永久磁石対ｍfrの前側の永久磁石184に吸着されて前方に移動し、右前永久磁石対ｍfrが右ガイド孔252Ｒの前端湾曲部252Ｒfに至り前側の磁石184が右ガイド孔252Ｒの直線から右側に外れると、右前脚部24Ｒの永久磁石Ｍfrの揺動軌道からも外れることになり永久磁石Ｍfrは前側の永久磁石184との吸着が円滑に解除され、後側の永久磁石184により反発されて前方に跳ね上げられる。   The left and right leg portions 24L and 25L of the horse model 20 swing along the straight portion of the left guide hole 252L, and the right and left leg portions 24R and 25R swing along the straight portion of the left guide hole 252R. Therefore, the permanent magnet Mfr of the right front leg portion 24R is attracted to the front permanent magnet 184 of the right front permanent magnet pair mfr and moves forward, and the right front permanent magnet pair mfr reaches the front end curved portion 252Rf of the right guide hole 252R and reaches the front side. When the first magnet 184 is released to the right from the straight line of the right guide hole 252R, the permanent magnet Mfr is also released from the swinging track of the permanent magnet Mfr of the right front leg 24R, and the permanent magnet Mfr is smoothly released from attracting the front permanent magnet 184. Then, it is repelled by the rear permanent magnet 184 and flipped forward.

同様に、左後脚部25Ｒの永久磁石Ｍrlが左後永久磁石対ｍrlの後側の永久磁石184に吸着されて後方に移動し、左後永久磁石対ｍrlが左ガイド孔252Ｒの後端湾曲部252Ｌrに至り後側の磁石184が左ガイド孔252Ｒの直線から左側に外れると、左後脚部25Ｒの永久磁石Ｍrlの揺動軌道からも外れることになり永久磁石Ｍrlは後側の永久磁石184との吸着が円滑に解除され、前側の永久磁石184により反発されて後方に跳ね上げられる。   Similarly, the permanent magnet Mrl of the left rear leg portion 25R is attracted to the permanent magnet 184 on the rear side of the left rear permanent magnet pair mrl and moves rearward, and the left rear permanent magnet pair mrl is curved at the rear end of the left guide hole 252R. When the rear magnet 184 reaches the portion 252Lr and moves to the left from the straight line of the left guide hole 252R, it will also move away from the swinging trajectory of the permanent magnet Mrl of the left rear leg 25R, and the permanent magnet Mrl Adsorption to 184 is smoothly released, repelled by the front permanent magnet 184, and flipped up backward.

このように、左右のガイド孔252Ｌ，252Ｒの前後両端を左右外側に湾曲させておくことで、脚部の足端部の吸着をいつまでも引きずることなく所定位置で速やかにかつ円滑に解除して足端部を跳ね上げることができる。
したがって、ガイド孔252Ｌ，252Ｒの前後長を短くすることができ、よってケース251を多少コンパクトにすることができる。 In this way, by curving the front and rear ends of the left and right guide holes 252L and 252R to the left and right, the feet can be quickly and smoothly released at a predetermined position without dragging the foot ends of the legs. The edge can be flipped up.
Therefore, the longitudinal length of the guide holes 252L and 252R can be shortened, and thus the case 251 can be made somewhat compact.

なお、本願発明は、４本の脚部を持つ模型体に限らず、人間のように２本の脚部を持つもの、あるいは昆虫のように６本の脚部を持つものなど複数の脚部を持つものに適用可能であり、さらには動物模型に限らず船模型などの複数のオールで漕いで移動するものも適用でき、その場合オールが脚部に相当する。   The present invention is not limited to a model body having four legs, but a plurality of legs such as one having two legs like a human or one having six legs like an insect. In addition, it is applicable not only to animal models but also to models that move in a plurality of oars such as ship models, in which case the oars correspond to the legs.

また、本願発明は、模型体が仕切板を隔てた駆動体とともに移動するものに限らず、駆動体の駆動により模型体が定位置で脚部のみを動作させるものにも適用可能である。   The invention of the present application is not limited to the case where the model body moves together with the driving body across the partition plate, but can be applied to the case where the model body moves only the leg portion at a fixed position by driving the driving body.
