A telescopic leg of a table consists of an outer tubular member, and an inner tubular member inserted in the outer tubular member; the outer tubular member is coupled to a top of a table, and has a bolt hole; the inner tubular member has a flat pressed side facing the bolt hole of the outer tubular member; a fixing bolt is passed through the bolt hole of the outer tubular member; the fixing bolt will closely touch the inner tubular member at a tail end thereof as well as making the inner tubular member tightly pressed against an inner side of the outer tubular member when it is turned tight; contact area between the fixing bolt and the inner tubular member is planar, and contact area between the inner tubular member and the inner side of the outer tubular member is also planar after the bolt is turned tight.
