Abstract
A housing (6) is provided in a reference block (1). An annular plug (9), which is to be inserted into a positioning hole (3) of a work pallet (2), is projected upward from the housing (6). An output member (13) is inserted into a guide hole (10) of the housing (6) vertically movably. An upper end of the output member (13) is inserted into the annular plug (9), and a plurality of pressing members (56) are supported on a peripheral wall (9a) of the annular plug (9) radially movably. An annular aligning space (31) is formed between a guided portion (21) of the output member (13) and the guide hole (10). A shuttle member (41), which is diametrically expandable and contractible, is inserted into the aligning space (31). The shuttle member (41) is urged upward by a spring (51).
