In the medical locating apparatus of the invention, the main parallel link (A) and the subsidiary parallel links (B1,B2) are formed by the first to third links (11-12,14), the first to third sub-links (24,25,26) and the crank member (23), in which the respective links are interlocked with the corresponding parallel links, respectively. Accordingly, clutch (C) means need not be disposed to all of the connection shafts of the links, but they may be disposed only to the pivot locating relatively at a low position, to the connection shaft connecting the first auxiliary link (21) with the first sub-link (24) and to the connection shaft connecting the second auxiliary link (22) with the second sub-link (25). Thus, the links need not be operated by the respective heavy clutches, the present apparatus enjoys excellent operability, and such constitution is also preferred from the standpoint of stability of the entire apparatus. <IMAGE> |
