Abstract

A washing machine capable of preventing a magnet, which detects a number of rotations of a washing shaft, from being removed from a predetermined position. The washing machine includes a drive motor to generate a rotating force. A washing shaft is rotated by the drive motor. A belt and a shaft pulley transmit the rotating force from the drive motor to the washing shaft. A magnet is mounted to the shaft pulley to rotate along with the shaft pulley. A magnetic sensor detects a number of rotations of the washing shaft, in response to a change in a magnetic field produced by the magnet. A locking unit is mounted at a first end thereof to the magnet, and at a second end thereof to the shaft pulley. Therefore, even when the vibrations caused by operations of the washing machine are transmitted to the magnet for a lengthy period of time, the magnet is connected to the shaft pulley by the locking unit without being removed from a predetermined position.
