A swing assembly includes a support frame, a pair of linking units, a seat unit, and a pair of pivot connecting units. The support frame has upright left and right frame portions adapted to be supported on a ground surface, and a horizontal bar interconnecting the left and right frame portions. The linking units are disposed between the left and right frame portions. Each of the linking units has an upper end connected pivotally to the horizontal bar, and a lower end. The seat unit is disposed between the linking units, and has two lateral arms proximate to the linking units. The pivot connecting units connect the lateral arms of the seat unit to the linking units, respectively. Each of the pivot connecting units includes an internally threaded tubular projection which projects from a respective one of the lateral arms of the seat unit toward an adjacent one of the linking units, a pivot hole formed in the adjacent one of the linking units, and a threaded rod having a first end which engages threadedly the tubular projection and a second end which extends through the pivot hole for mounting pivotally on the adjacent one of the linking units at the pivot hole such that a clearance is formed between the respective lateral arm and the adjacent linking unit.
