This creation discloses a kind of combined structure of colloid massage ball, is to be constituted comprising right hemisphere and left hemisphere body. The right hemisphere has the lug end of circular, and left hemisphere body has the groove of circular； Lug end can be mutually chimeric with groove and generates contact surface, and when right hemisphere is chimeric by jig with left hemisphere body and rotates, right hemisphere and left hemisphere cognition generate high temperature because of spin friction, then dissolves the two surface and closely combines. 本創作揭露一種膠質按摩球之結合構造，其係包含右半球體與左半球體所構成。該右半球體具有正圓形之凸片端，左半球體具有正圓形之凹槽；凸片端與凹槽可相互嵌合並產生接觸面，當右半球體與左半球體受治具而嵌合並旋轉時，右半球體與左半球體會因旋轉摩擦而產生高溫，遂將二者表面溶融而緊密的結合。
