Abstract
A loop device includes an endless thread threaded through a number of balls, and a number of spacers disposed between the balls. The balls may apply force against human body for exercising and massaging purposes. The endless thread includes a wire cable for preventing stretching of the endless thread, and a soft covering engaged on the wire cable. The soft covering is engaged between the wire cable and the balls for reducing friction between the wire cable and the balls and for reducing noise.
