Wobbling toy

A steering device for a toy including: right and left turning members for turning right and left steering wheels in clockwise and counterclockwise directions around predetermined shafts; and a connecting member for connecting and forming a turning pair with each turning member. The right and left turning members are turned around each predetermined shaft by moving the connecting member in right and left directions so as to change each direction of the steering wheels. One of a coil and a magnetic body is provided on the connecting member, the other of the coil and the magnetic body is fixed to a fixing portion of the toy, and the coil and the magnetic body come close to and go away from each other by moving the connecting member. The connecting member takes at least two steering positions by controlling a current to be carried to the coil with a coil current carrying unit.

Steering device for toy

An attachment structure for motor and a racing vehicle toy, wherein a motor can easily be inserted and removed therefrom, including a motor holding plate pivoting relative to a toy chassis between an open position for opening the motor containing part and a close position for closing the motor containing part. The motor holding plate includes a member to elastically engage the chassis, when the motor holding plate is in the closed position, thereby holding the motor in the motor containing part.

Attachment for motor for toy

A motor with a plurality of electrode terminals, wherein at least a portion of a case for the motor forms at least one of the plurality of electrode terminals.

Motor and attachment structure

An attachment structure for motor and a racing vehicle toy, wherein a motor can easily be inserted and removed therefrom, are provided. The attachment structure includes a motor holding plate capable of turning on a predetermined rotational shaft line attached to a chassis or base body. The motor holding plate includes an engaging portion capable of elastically engaging with an engage portion provided on the chassis when the motor holding plate is at the close position. The motor holding plate is capable of taking up an open position for opening the motor containing part and a close position for closing the motor containing part the turning. The motor holding plate holds the motor in the motor containing part in the close position.

When an electric motor is rotated normally, a left-hand driving wheel is rotated normally by a drive gear through a large gear, a left-hand small gear, and a left-hand driven gear, and a right-hand driving wheel is also rotated normally through a right-hand small gear, a swing gear, an intermediate gear, and a right-hand driven gear, thereby causing the vehicle toy to run straight. When the electric motor is switched to a reverse rotation, the left-hand driving wheel is rotated reversely, and the swing gear is brought into engagement directly with the right-hand driven gear to rotate the right-hand driving wheel normally. As a result, the vehicle toy makes a continuous turn at a small radius of rotation. Since the swing gear is turnably attached to a switch arm which is capable of turning about a gear shaft of the large gear, the swing gear is moved in accordance with the normal rotation and reverse rotation of the right-hand small gear, and brought into engagement with either of the intermediate gear and the right-hand driven gear.

Drive apparatus for vehicle toy

A steering device for an automotive vehicle toy comprises a motor to be driven by a remote control operation, a steering mechanism having a return spring for biasing steering wheels into a neutral position, and a clutch for transmitting a driving force of the electric motor to the steering mechanism against the return spring. The clutch includes a holding disc, clutch elements engageable with the holding disc such that the clutch elements can be moved in a radial direction of the holding disc by a centrifugal force, and an outer cylindrical member concentrically accommodating the holding disc and the clutch elements in it, and firmly secured to the mechanical reduction gear. A plurality of engaging groove portions are formed in the holding disc at equal spaces through a partition wall. An engaging element engageable with the engaging groove portions is formed on an inner side of that outer peripheral portion of each clutch element which is brought into pressure contact with an inner peripheral surface of the outer cylindrical member. Each engaging element has a cut portion engageable with the partition wall. The clutch elements are engaged with either the engaging grooves or the partition wall such that the clutch elements are slidable in the radial direction.
