Balance Device Having Height Adjustable Function

Abstract

A balance device includes an adjusting seat, and a balance board detachably mounted on the adjusting seat. The adjusting seat has an open upper portion formed with a mounting hole and a closed lower portion formed with a protruding rocking portion. The upper portion of the adjusting seat has a peripheral wall formed with a plurality of elongated locking grooves. The balance board has a bottom formed with a protruding block inserted into the mounting hole of the adjusting seat and a plurality of locking ribs each inserted into one of the locking grooves of the adjusting seat. Thus, the height of the balance board relative to the adjusting seat is adjustable so that the balance board is located at different heights to facilitate a user practicing the balance skill at different heights.
