Intended is to provide a method for positioning a work (15), which is adapted for a knock hole of a small diameter and which can absorb a pitch error between a main positioning hole (16) and an auxiliary positioning hole (17) of the work (15). An insert shaft (21) of main positioning means 820) is inserted into the main positioning hole (16). Auxiliary positioning means (30) includes a base lower block (36) having a parallel slide holding surface (36e), a sliding flange (34b) having a sliding surface (34c), and an insert shaft (31) disposed above the sliding flange (34b). The sliding flange (34b) of the auxiliary positioning means (30) is guided and moved by the slide holding surface (36e), and is inserted, while absorbing the pitch error, into the auxiliary positioning hole (17), thereby to position the work (15).
