Abstract

The utility model discloses a minitype driving gear box applied to a small-sized toy, which comprises a shell and a shell cover, wherein the shell cover is arranged on the shell; a containing space is formed between the shell and the shell cover; the containing space is internally provided with a motor, a gear A, a gear B, a gear C, a gear D and a gear E; the gear A is arranged on an output shaft of the motor; the gear A is meshed with the gear B by an intersecting-axis gear in a transmission way; the gear B is meshed with the gear C by a parallel-axis gear in a transmission way; the gear C is meshed with the gear D by another parallel-axis gear in a transmission way; the gear D is meshed with the gear E by another parallel-axis gear in a transmission way; the gear E is provided with a transmission shaft; and the shell, the shell cover, the gear A, the gear B, the gear C, the gear D and the gear E are made of polyformaldehyde. The gear box is small in volume and high in transmission accuracy.
