• wherein the armrest body further includes an armrest opening which is formed by an opening of the armrest pad, an opening of the armrest cover, and an opening of the armrest base aligned and communicating with one another vertically;
• a first component which is mounted in the rectangular space of the armrest body, arranged at the first sliding slot of the armrest base, and provided with a widthwise second hole corresponding to the first hole;
• wherein the armrest body is moved relative to the first component in the lengthwise direction by the first sliding slot;
• a second component which is mounted in the rectangular space of the armrest body, disposed on the first component, and having a locking hole corresponding to both the second hole and the first hole;
• a mounting seat which is disposed on a top surface of the armrest rod for loading the armrest body and provided with a protruding axis able to be inserted through the first hole and the second hole from bottom to top in turn to be abutting against and stopped under the locking hole of the second component;
• the armrest body being disposed on the mounting seat by a fastener being inserted through the locking hole of the second component from top to bottom and fastened into the protruding axis of the mounting seat;
• and
• a button which is inserted into the armrest opening, located in the opening of the armrest base, and composed of a plate portion on an outer end thereof, an elastic member located on an inner end thereof and elastically abutting against a protruding wall on each lateral side of the opening of the armrest base, a lengthwise connecting and sliding portion arranged between the plate portion and the elastic member, a protrusion portion mounted to an inner wall of the connecting and sliding portion, and a lengthwise button rack arranged at the protrusion portion and engaged with a third rack of the first component;
• wherein the plate portion of the button is pressed and elastically moved inward from the armrest opening and the button rack on the protrusion portion of the button is moved inward and disengaged from the third rack of the first component when the button is pressed inward;
• now the first component, the second component, the mounting seat and the protruding axis remain still while the armrest body is moved relative to the first component, the second component, the mounting seat and the protruding axis in the lengthwise direction by the first sliding slot for position adjustment.
