摘要 |
A flat portion 12 a and a slope portion 12 b are provided on a thread 12 of a multi-pitch screw 10 alternately. The flat portion and the slope portion are provided on the thread of a multi-pitch nut which fastens with this. Consequently, a screw and a nut capable of preventing loosening securely by step are achieved. This enables comfortable and quick feeding and when a torque from a driving source is interrupted, step-like self-lock is activated.
