Abstract
A headrest adjusting structure for a seat comprises a base and a rotating support. The base is formed with a groove for receiving a supporting portion of the rotating support which has outwardly cavities. The base has outwardly accommodating spaces which is formed with an aperture for receiving a ball and resilient element on two sides. Each ball has an end engageable with the corresponding recess on the positioning disk mounted in the rotating support. A threaded fastener can penetrate the pressing plates fitted in the accommodating spaces of the base, the base and the supporting portion of the rotating support, and be screwed into a nut to hold together. A cap is mounted on each accommodating space of the base. A headrest which is combined at the headrest adjusting assembly installed on a seat can be adjusted to a preferred position by manually pulling the rotating support easily.
