A washing machine may suppress variation in horizontal vibration of a spin basket without performing a control operation. A balancing device includes a ring-shaped casing installed to be concentric with the spin basket, and a plurality of the balancing balls and a viscous fluid. A ring-shaped ball accommodation portion, a fluid accommodation portion provided at a lower inner side of the ball accommodation portion in a radial direction of the ball accommodation portion for accommodating the viscous fluid, and a communication channel for communicating the ball accommodation portion to the fluid accommodating portion are formed in the casing. The fluid accommodation portion is provided at a portion of the casing along a circumferential direction of the casing. A bottom surface of the ball accommodation portion is inclined downward as the bottom surface extends from a position of the fluid accommodation portion to an opposite position such that the balancing balls gather at the opposite position facing the fluid accommodation portion when rotation of the spin basket is stopped. |
