摘要： A thin spiral spring drive unit, in particular for a toy car, employs a crown gear in a gear train between an output shaft and a drive shaft on which a spiral spring is wound as a source of the driving force. The unit can be assembled with a small number of component parts, in a simple structure and at lower cost. Simply by changing the direction of the output shaft when it is assembled into a gear box, the direction of rotation of the output shaft may be changed. The crown gear in the drive unit is arranged at a position substantially centeral to the width of a gear box. A pinion is arranged at two positions where the crown gear intersects with the output shaft to be meshed with the crown gear by means of a positioning mechanism. The crown gear is provided on its periphery with a windup gear and with a driving pinion on the shaft thereof so that the windup gear is engaged with a gear at the time of winding while it is directly engaged with a driving gear at the time of driving.

摘要： The present invention is a pull-back, windup type spring drive unit with two output shafts capable of transmitting driving force to the front-wheels and rear-wheels. This unit is provided with: a frame; front-wheel and rear wheel output shafts; a drive gear; a spring; a windup gear mechanism; first and second running gear mechanisms connectable to the front-wheel and rear-wheel shafts; and a constant speed mechanism. When one of the output shafts is rotated for winding, switching gear of the windup gear mechanism moves to a mesh position and the rotation of the output shaft for winding is transmitted to the drive gear to wind up the spring. When the drive gear is rotated for running, switching gears of the respective running gear mechanism move to the respective mesh positions to transmit the rotation of the drive gear to each of the output shafts.

摘要： A two-speed windup drive unit which can automatically switch and output two types of rotations with a spring being used as a power source. Switching gears 16 and 17 which move around one gear 10 in a gear mechanism 2 which transmits output rotations in order to disconnectably connect a constant speed mechanism 3 are provided in a long hole 23 which is arranged at a position crossing a movement trajectory of a switching member 6 which starts a linear movement simultaneously with start of outputting rotations and a position at which a force causing falling toward a pinion of the constant speed mechanism 2 by the gravitational force, the gears 16 and 17 are rapidly moved in a direction along which the gears 16 and 17 mesh with the constant speed mechanism 3 by the gravitational force and a revolving force generated by rotations of the gear 10 so that the constant speed mechanism is connected with the gear mechanism, and the gears 16 and 17 are disconnected from the constant speed mechanism 3 against the gravitational force and the revolving force by the switching member 6 when the gears 16 and 17 have moved by a fixed distance from start of outputting rotations.

摘要： A windup spring drive unit improving the operability of winding when incorporated in an apparatus such as a toy, and increasing a degree of freedom in design. The windup spring drive unit comprises: a spring 2 as a power source; a windup shaft 3 which manually winds up the spring 2; an output shaft 4; and a gear train 5 which transmits the power of the spring 2 to the output shaft 4, these members being accommodated in a casing 6. A crown gear 8 is included in the gear train 5, the crown gear 8 has its center of rotation axis being arranged in parallel with the windup shaft 3. The output shaft 4 and the windup shaft 3 are arranged to be orthogonal to each other, and the windup shaft 3 is provided to pierce in a thin direction t of the casing 6.
