A cable system A in which a cable 3 can be prevented from becoming slack when a travelling body 2 completes ascending, starts descending or completes descending stairs, a step or bump is provided. The cable system A includes the cable 3 connecting a base device 1 and the travelling body 2, a reel device 10 disposed on the travelling body 2, a motor controller 40 that controls a motor 15 of the reel device 10 and an acceleration sensor 50 that detects an acceleration of the travelling body 2 in a vertical direction. The motor controller 40 basically makes the motor 15 free when the reel 12 is rotated in an unreeling direction and the motor controller 40 basically provides the reel 12 with a rotary torque in a reeling direction when the reel 12 is rotated in the reeling direction. Moreover, even when the reel 12 is rotated in the unreeling direction, the motor controller 40 provides the reel 12 with the rotary torque in the reeling direction if an end of sudden change of attitude of the travelling body 2 such as when a front or a rear of the travelling body 2 is suddenly moved downward is detected based on information on acceleration in the vertical direction obtained from the acceleration sensor 50.
