Spur gears 11, 11 fixed to support shafts 10, 10 of front wheels 9, 9 attached to the lower portions of rotating arms 8, 8, which are attached via the front wheels 9, are meshed with each other. Further, a pinion 47 fixed to the rear end is meshed with a crown gear 53 forming a castor movable gear U. Further, a pinion 48a fixed to the center portion is meshed with a crown gear 60 forming a rear wheel movable gear portion V. By positioning the switch member 79 at F, the vehicle can move forward, and by positioning it at RW, the vehicle can move backward. At this time,
The castors 55, 55 are also rotating, but remain hidden by the folded robot leg member 1b. Further, when using the winch, by positioning the conversion lever member 51 at W, the support shaft 45 forming the main gear portion S moves rearward, and the pinion 46, the crown gear 49, the pinion 48a and the crown gear 6
The zero mesh state is released, and the pinion 46 is meshed with a spur gear 77 linked to the main gear W forming the winch mechanism. By placing the switch member 79 in the RW position, the rope 69 is wound around the winding drum 70 of the winch mechanism via the main gear W. Note that at this time, the toy car A is maintained in a stopped state.

Next, if you want to enjoy playing by changing from the car form to the robot form, rotate the chassis 1 and the car body 2 approximately 180 degrees around the support shafts 4, 4, as shown in Figure 3 a to e. Then, the tip of the bonnet member 3 attached to the vehicle body 2 so as to be openable and closable is fitted into a fitting groove 7 having a concave shape formed on the bottom surface of the vehicle chassis 1. As a result, the chassis 1 and the vehicle body 2 are reliably supported in the unfolded state, and the robot leg member 1a and the robot body member 2a are formed. A robot foot member 1b provided at the rear of the chassis 1
By rotating approximately 90 degrees, the uprightness can be stabilized, and as shown in FIGS. 2 and 5, a mounting member on which a pinion 65 forming the rear wheel movable gear portion V is pivotally supported. The base end 67a of the pinion 67 is pressed, and the pinion 65, which is meshed with both the pinion 62 and the spur gear 64 fixed to the support shafts of the rear wheels 58, 58, is released, and the foot Cars 55, 55 are exposed at the bottom.
As a result, the rear wheels 58, 58 do not rotate in the robot mode. Next, the rear member 16, which can be divided into three parts, is divided and the arms 21, 21 of the robot are deployed on both sides of the robot body member 2a, and the back member 20 is attached to this robot body member via the support members 18, 18. It may be placed on the back side of 2a.
As a result, a toy transformed into the form of a robot is obtained. Then, by positioning the conversion lever member 51 in the R position and switching the switch member 79 to F or RW in the same way as in the car form, the toy that has been changed into the robot form is exposed at the bottom. By rotating the castors 55, 55 in the forward and reverse directions, the robot toy can walk forward and backward. Further, since the configuration of this drive mechanism is the same as that in the above-mentioned automobile form, a description thereof will be omitted.

In addition, when changing from this robot form to an automobile form, each member may be rearranged in the opposite manner to the above.

As mentioned above, the shape-changing traveling car toy A can be easily changed from a car form to a robot form by simply rearranging and connecting each member, and when in the car form, the driving force from the electric motor 40 is transferred to the main gear part S. It can be transmitted to the front wheel movable gear part T and the rear wheel movable gear part V via the front wheel movable gear part V to drive the vehicle. In addition, the vehicle can freely move forward or backward by simply switching the switch member 79. Furthermore, even in the robot form, the robot can be made to walk via the castors 55, 55, thereby doubling the fun of play. Furthermore, by simply switching the conversion lever member 51 when in the vehicle mode, the main gear part W can be moved to rotate the winding drum 70 of the winch mechanism to wind up the rope 69. In this way, you can enjoy three different types of play, which is economical, and the range of play is expanded, so you never get bored.

In the above embodiment, the shape-changeable traveling car toy A has been described as changing from a car shape to a robot shape, but the present invention is not limited to this, and the shape can also be changed in the opposite manner, for example.
