Abstract
A seat post assembly includes an outer tube, an inner tube disposed movably in the outer tube, a sealing element disposed on the top end of the outer tube to fill the gap between the outer and inner tubes, and a bushing rotatably disposed on the top end of the outer tube and penetrated by the inner tube. The bushing has an exposed portion located in the sealing element or the outer tube in such a manner that the exposed portion isn't shielded and can be touchable, and a barrel portion coaxially connected with the exposed portion and located in the outer tube and having a bottom abutted against a protrusion of the inner tube for limiting the ascending height of the inner tube. Therefore, the present invention allows a rider to touch the bushing without taking it out, thereby facilitating the total height adjustment of the inner tube.
