The present invention provides a foldable chair frame comprising: two leg support column units; two back column units; a support bar unit; and a linkage unit. The linkage unit includes at least one link set which includes two linkages each of which is pin-jointed to the back column units. Each linkage includes a first pin-joint part pin-jointed to the back column unit at the same side and a second pin-joint part opposing the first pin-joint part. The linkage unit operates between an unfolded location and a folded location. The link set is stretched in a left and a right direction in the unfolded location, and the link set is folded to make the leg support column units come close to each other in the folded location. According to the structure of the present invention, bar elements approach each other both in a front and a back direction and in a left and a right direction when folded, and storing is convenient since volume is reduced after being folded. |
