The present invention is to provide an apparatus for tree pruning capable of efficiently cutting not only large branches, but also small branches without aid of any other apparatus, and effectively reducing unpruned branches as well as branch clogging and catching of the branch-receiving members, so that the workability of pruning trees at high positions can be improved.Branch-receiving members 30 and 40 mounted on side surfaces of a guide bar 20 at predetermined intervals in a longitudinal direction thereof have attachment base portions 32 and 42 attached to the side surfaces of the guide bar 20 and branch-receiving projection portions 35, 36, 45, and 46 being continuous to the attachment base portions 32 and 42 through outward bending portions 33 and 43 and projecting above or below the guide bar 20 the branch-receiving members 30 and 40 are mounted on both left and right side surfaces of the guide bar 20, such that the branch-receiving projection portions 35 and 45, and 36 and 46 face each other across the saw chain 22 and projecting heights of the branch-receiving projection portions 35 and 45, and 36 and 46 of the branch-receiving members 30 and 40 in a left and right pair are different from each other.
