ABSTRACT:
An adjusting structure for an armrest of a chair comprises a support member, an armrest, a side cover, a press member, a guiding member, a housing, and an engaging unit; wherein in operation, the press member is pressed inward to disengage the guiding member from the limiting recess of the support member. Thereafter, the armrest is adjusted to tilt forward so that the screw elements and the guiding member are guided toward a predetermined orientation along the arcuate groove, and the engaging unit abuts against the support member, thereby positioning the armrest.
