, The back surface of the toe member 127 and the back surface of the heel member 129 are joined to close the foot member 125.

When the operation lever 210 of the main switch 209 provided on the left side of the apparatus main body 13 is slid to one side, the drive motor 161 is rotated, and this rotation is performed by the drive pinion 169, the spur gear 173, the input shaft 171, the pinion 1
The speed is reduced by a reduction gear portion 163 including a gear 75, a spur gear 177, and a pinion 181 and transmitted to the spur gear 183. The rotation of the spur gear 183 is performed by the pinion 187 and the spur gear 1.
99, pinion 201, spur gear 203, drive pinion 2
The transmitted power is transmitted to the driven spur gear 51 via the transmission line 05. The spur gear 53 integral with the driven spur gear 51 also rotates, and attempts to rotate the spur gear 57 that meshes with the spur gear 53.

The spur gear 57 rotates integrally with the toothed belt wheel 59. Since the toothed belt 67 is wound around the toothed belt wheel 59, the rotational load is large. Does not rotate. Therefore, the driven spur gear 51
When rotated about the intermediate shaft 49, as shown in FIG. 9B, the spur gear 57, which is non-rotatably meshed with the spur gear 53, the toothed belt wheel 59, the toothed belt 67, the toothed belt wheel 63, Rotation shaft 61, operation connecting member 43, and upper body 33
Rotate about the intermediate shaft 49 so as to stand from the rear to the front.

When the operation connecting member 43 rotates, the push-up protrusion 44 provided on the back surface does not push up the engagement protrusion 155. Therefore, the operation connecting rod 141 is urged downward by the elasticity of the spring 143. Actuating connecting rod 1
41, the toe members 127 and the heel member 129 push down the long holes 138, 139, and the toe members 12
7 and the heel member 129 open to form the foot member 125.

When the operation connecting member 43 starts to stand up, the rotation of the spur gear 53 causes the spur gear 57 to rotate. The rotation of the spur gear 57 is controlled by the toothed belt wheel 59, the toothed belt 67,
The power is transmitted to the spur gear 97 via the toothed belt wheel 63 and the spur gear 65. The spur gear 97 includes pinions 99, 99, crown gears 91, 91, a trunk pulley 9 via a rotation shaft 95.
Since the rotation of the third and the third 93 is attempted, the rotation load is large and the rotation is not performed at first. Accordingly, the spur gear 97 rotates around the rotation shaft 61. The spur gear 97 is
, The upper body 33 also rotates about the rotation shaft 61. Therefore, as shown in FIG. 9B, the upper body 33 rotates in the direction in which the operation connecting member 43 separates as the operation connecting member 43 stands.

When the upper body 33 starts rotating, the spur gear 97
Also rotate. The rotation of the spur gear 97 is transmitted to the rotation shaft 95, the pinion 99, the crown gear 91, the body pulley 93, and the rubber belt 111 to try to rotate the shoulder pulley 105. However, since the rotation load of the shoulder pulley 105 is large, it does not rotate smoothly, and the shoulder pulley 1
The shoulder 35 is rotated about the trunk connection shaft 89 such that the pulling force of the rubber belt 111 that rotates the shoulder 05 pulls the shoulder pulley 105 and the shoulder connection shaft 103 sideways. The shoulder 35 stops rotating when it comes into contact with the back wall 86 of the storage chamber 81.

The shoulder pulley 105 is connected to the shoulder connecting shaft 103.
, So that it starts to rotate smoothly and tries to rotate the elbow pulley 119. However, since the rotation load of the elbow pulley 119 is large, it does not rotate smoothly, and the pulling force of the rubber belt 121 for rotating the elbow pulley 119 is reduced.
The upper arm body 37 is rotated about the shoulder connection shaft 103 by pulling the elbow connection shaft 117 downward.
The upper arm 37 stops rotating when its end comes into contact with one side of the shoulder 35.

The elbow pulley 119 also starts rotating, and the lower arm 39 integral with the elbow pulley 119 also rotates. Lower arm 39
Stops turning when its end abuts against one side of the upper arm body 37.

As described above, when the operation connecting member 43 stands up, the upper body 33, the shoulder body 35, the upper arm body 37, and the lower arm body 39 rotate individually. When the upper body 33 is substantially perpendicular to the operation connecting member 43, as shown in FIG. 9 (c), the tip rotates the leading body 25 forward against the elasticity of the spring 28, and the leading end moves to the leading end. It engages the rear end 29 of the body 25. When the front end of the upper body 33 is engaged with the rear end 29 of the front body 25, the rotation of the operation connecting member 43 stops.

Working connection member 43, upper body 33, shoulder 3
5, when the rotation of the upper arm body 37 and the lower arm body 39 is stopped to change to the robot form, the driven spur gear 51, the drive pinion 20
5. The rotation of the output shaft 185 and the spur gear 203 stops. The pinion 201 moves while engaging with the spur gear 203 to continue rotation. As a result, the swing member 189 to which the pinion 201 is attached via the rotation shaft 197 swings about the output shaft 185, and the operation members 195 and 196 provided on one side are operated by the operation lever 21 of the sub switch 211.
3, the drive motor 161 is short-circuited, the electric brake is operated, and the drive of the drive motor 161 is forcibly stopped.

As described above, when the operating lever 210 of the main switch 209 is slid to one side, the automatic deforming device 11 changes from the airplane mode to the robot mode until the operating lever 213 of the sub switch 211 is operated. Will be. Further, when the operation lever 210 of the main switch 209 is slid to the other side from the robot mode, the automatic deformation device 11 changes to an airplane mode until the operation lever 213 of the sub switch 211 is operated. The operation connecting member 43, the upper body 33,
When a load is applied to a part or the entirety of the shoulder body 35, the upper arm body 37, and the lower arm body 39, and an abnormal situation in which rotation is impossible occurs, the rotation of the driven spur gear 51 stops. When the switch 211 is operated, the driving of the drive motor 161 is stopped, and no load is applied to the drive motor 161 and heating is not performed.

The overload stop mechanism 160a shown in FIG. 2 differs from the above embodiment in that the reduction gear section is omitted and the drive motor 1
61a drive gear 169a directly into spur gear (driven gear)
183a. The overload stop mechanism 160b shown in FIG. 3 is a swing member 1 composed of one side plate.
