PROBLEM TO BE SOLVED: To enable easy attachment/detachment with a single operation by forming a pair of protrusions having slant surfaces on a rod-shaped extension part (carrying shaft), forming the connection member of connector to be fitted around the extension part into two-forked form, and forming a pair of openings into which the protrusions are fitted at each divided part. SOLUTION: A pair of protrusions 13, 14 having slant surfaces 15a, 15b extending while gradually rising toward a base end 12 is formed in the vicinity of the end 12. A cylindrical recess 22 extending toward the inside from a base end 21 of a connection member 20 to be mounted on the outer surface of the shaft 10 is formed on the connection member 20 of the connector for electric medical operation. A pair of slots 25a, 25b are formed along the recess 22 and two branch parts 26a, 26b are defined at a part on the side of base end of the member 20. Opening 28a, 28b are formed respectively at the branch parts 26a, 26b and the protrusions 13, 14 are made to engage with the openings 28a, 28b, respectively with the branch parts elastically deformed when the connection member 20 is fitted around the shaft 10. |
