  • the lower front wheel chassis 51 and the upper front wheel chassis 52 engage with each other.
  • An electric circuit board 53 which receives a control signal from a remote controller 8, described later, to drive each portion, is placed on the lower front wheel chassis 51, and the electric circuit board 53 is covered by the upper front wheel chassis 52.
  • a steering motor and a gear mechanism which are not shown, are mounted on the lower front wheel chassis 51, and a steering rack 54, coupled to the front wheels 21, 21, is supported in parallel with the front wheel axle 2 so as to be movable in a right and left direction.
  • These parts constitute a steering mechanism of the automobile toy 1.
  • the steering motor drives the steering rack 54 right and left through the gear mechanism, and thereby the front wheels 21, 21 change their directions right and left.
  • the automobile toy 1 is thus steered.
  • a battery is mounted on the lower front wheel chassis 51.
  • a drive motor 62 having a motor shaft coupled to the rear wheel axle 3, is mounted in the rear end portion of the rear wheel chassis 6.
  • the rear wheel chassis 6 includes two arms 61, 61, extending forward along both-side portions of the automobile 1, and the rear wheel chassis 6 is formed in an almost U-shaped in a planar view.

  • Respective end portions 61a of the two arms 61, 61 are coupled to coupling portions 55, provided as projections in the both-side portions of the front wheel chassis 5, with the two arms 61, 61 separated from each other in the vehicle width direction, with the rear end portion of the front wheel chassis 5 put between the arms 61, 61.
  • FIG. 3 is a sectional view viewed from arrows A in FIG. 2
  • FIG. 4 is a sectional view viewed from arrows B in FIG. 2
  • FIG. 3 shows the figure in which gaps between each part are widened in order to make the figure easy to understand.
  • a hemispherical first projecting portion 52a projecting downward and formed on the upper front wheel chassis 52
  • a hemispherical second concave portion 51a opening upward and formed on the lower front wheel chassis 51
  • a hemispherical first concave portion 61b opening upward complementarily to the first projecting portion 52a
  • a hemispherical second projecting portion 61c projecting downward complementarily to the second concave portion 51a, are formed at each of the end portions 61a of the arms 61, 61, with the first concave portion 61b and the second projecting portion 61c mutually concentric.
  • Each of the end portions 61a of the arms 61, 61 is nipped by the upper front wheel chassis 52 and the lower front wheel chassis 51 from above and below in such a way that the first projecting portion 52a and the first concave portion 61b are slidably fitted to each other, and that the second projecting portion 61c and the second concave portion 51a are slidably fitted to each other.
  • each of the two arms 61, 61 is formed in a flat plate inclining toward the inside of the automobile toy 1 in the vehicle width direction in the neighborhood of each of the end portions 61a as shown in FIG. 4 .
  • each of the arms 61, 61 is formed to be horizontal at its base end portion, shown by chain double-dashed lines in the figure, and to incline more to the inside as its position becomes closer to the end portion 61a thereof.
  • the arm 61 can disperse the external force according to the inclination angle thereof, and the load which operates on the arm 61 into the vehicle width direction can be reduced.
  • each of the two arms 61, 61 is made of a twistable elastic member. Consequently, by the twisting of the arm 61, a twist angle between the front wheel chassis 5 and the rear wheel chassis 6 can be enlarged. In addition, because each of the arms 61, 61 can elastically be deformed into the vertical direction, the suspension function of the automobile toy 1 can be strengthened.
  • FIG. 5 is a partial sectional view of the rear end portion of the automobile toy 1.
  • the wing member 7 is coupled to the rear wheel chassis 6 through the intermediary of a stay member 71, made of an elastic member.
  • the stay member 71 has a bent portion bent in S in the front and rear direction, and only one stay member 71 is attached to the central part of the wing member 7 in the vehicle width direction (see FIG. 1 ).
  • a local stress concentration on the stay member 71 is moderated, and plastic deformation and breakage of the stay member 71 can be prevented, even if the wing member 7 touches a wall or a road surface owing to an overturn or the like of the automobile toy 1.
  • a spring member 63 is fixed to the front end portion of the stay member 71, and the other end of the spring member 63 is fixed to a projecting portion 52b at the rear end of the upper front wheel chassis 52.
  • the spring member 63 biases the front wheel chassis 5 and the rear wheel chassis 6 into almost the vertical direction and mainly fulfills the function of a suspension.
  • locking portions 51b, 51b, projecting rearward are formed in the rear end portion of the lower front wheel chassis 51, and projections 6a, 6a, projecting forward, are formed over the locking portions 51b, 51b at the front end portion of the rear wheel chassis 6 (see FIG. 2 ).
  • These locking portions 51b, 51b and projections 6a, 6a are provided for regulating the relative rocking of the front wheel chassis 5 and the rear wheel chassis 6 in the vertical direction around the end portions 61a of the arms 61, 61.
  • the end portions 61a of the arms 61, 61 are prevented from being dropped off from the coupling portions 55, and a wiring between the electric circuit board 53 and the drive motor 62 is prevented from being exposed.
  • the biasing force of the spring member 63 is adjusted so that the locking portions 51b, 51b and the projections 6a, 6a are stabilized in the state of being separated by a predetermined distance in the vertical direction in their normal states.
  • FIG. 6 is an appearance view of the remote controller 8 for remotely operating the automobile toy 1.
  • the remote controller 8 is equipped with a lever portion 81 for driving the drive motor 62 to advance or reverse the automobile toy 1, and a steering wheel portion 82 for driving the steering motor to steer the automobile toy 1.
  • the present embodiment is configured so that a user operates the lever portion 81 with the left hand grasping a grip portion 8a, and operates the steering wheel portion 82 with the right hand.
  • the automobile toy 1 When the lever portion 81 is moved from its neutral state into the F direction in the figure, the automobile toy 1 is advanced. When the lever portion 81 is moved from its neutral state into the B direction in the figure, the automobile toy 1 is reversed after being braked for a predetermined time. Furthermore, a projecting portion 81a is formed in the B-direction part of the lever portion 81 which projects into the direction (front side of FIG. 6 ) opposite to the steering wheel portion 82. Thereby, the remote controller 8 is configured so that an operating finger (for example, the forefinger of the left hand) does not easily slip out at the time of operating the lever portion 81 into the B direction.
  • an operating finger for example, the forefinger of the left hand
  • the steering wheel portion 82 is configured to be able to drive the steering motor to steer the automobile toy 1 to the left and the right sides by being rotated from its neutral state to the left or the right directions.
  • the remote controller 8 is equipped with a frequency setting button 84 for switching the operable automobile toy 1, besides an electric power switch 83.
  • a frequency setting button 84 for switching the operable automobile toy 1, besides an electric power switch 83.
  • FIG. 7 is an appearance view of a charger 9 for charging the battery of the automobile toy 1.
  • the stay member 71 includes the bent portion, bent into the front and rear direction of the automobile toy 1. Consequently, even if an external force into the front and rear direction of the wing member 7 operates on the stay member 71, the external force can be dispersed according to the bent angle of the bent portion. Furthermore, because the bending makes the stay member 71 easy to elastically deform, plastic deformation of the stay member 71 can be suppressed.
  • the stay member is made to be easily elastically deformed, and plastic deformation of the stay member 71 can be suppressed because the stay member 71 is made to be longer by the bending, in comparison with the lengths of the conventional straight stay members.
  • the stay member 71 is made of an elastic member, the say member 71 is made to be more easily elastically deformed, and plastic deformation and breakage of the stay member 71 can further be suppressed.
  • the stay member 71 is configured to include a bent portion in the aforesaid embodiment, the stay member 71 may be the one consisting of the bent portion, that is, the one having no straight line portions.
  • the shape of the bent portion of the stay member 71 is not limited to the S shape, but may be a dogleg shape, a Z shape, and the like, as long as the bent portion is bent in the front and rear direction.
  • the bent portion of the stay member 71 may be the one bent in the horizontal direction.
  • the "bending" in the present invention is a broad concept including “curving” and “zigzagging,” and the like, regardless of how the bent portion is bending.
  • an overturn prevention ring 10 shaped in almost a belt, on the automobile toy 1.
  • the overturn prevention ring 10 is made of a transparent polycarbonate and is fixed to the back surface of the lower front wheel chassis 51 to enclose the automobile toy 1 at almost the central part in the front and rear direction.
  • two projections 10a, 10a are formed at the top end of the overturn prevention ring 10 projecting into the front and rear direction. The positions of the two projections 10a, 10a in the circumferential direction are different from each other, with the center of the vehicle width direction between the two projections 10a, 10a.
  • the automobile toy 1 can be protected, and further if the automobile toy 1 is likely to overturn, the overturn prevention ring 10 touches a wall or a road surface to make it possible that the automobile toy 1 restores its posture. Furthermore, even if the automobile toy 1 has been inverted, the projections 10a, 10a make the inversion state unstable, because the automobile toy 1 is supported by a pointed end of one of the projections 10a, 10a. Therefore, the posture of the automobile toy 1 can be restored by causing a reaction by steering the front wheels 21, 21 or driving the rear wheels 31, 31.
