PROBLEM TO BE SOLVED: To provide a medical instrument maintaining smooth operation and high functionality with a bolt and a nut hardly becoming loose.SOLUTION: A medical instrument formed by crossing the distal ends of operating parts 14, 14 having resilient members 11, 12, and connecting the distal ends by a journal part 13 to provide the distal ends with function parts 11a, 12a for gripping, holding, cutting, etc., is configured to operate the function parts 11a, 12a by changing a pressing force applied to the resilient members 11, 12. The journal part 13 includes a shaft body 131 inserted through a crossing part for crossing the distal ends of the operating parts 14, 14; a caulking part 131a caulking one end of the shaft body 131; and a sliding member 133 fittingly mounted between the crossed operating parts 14, 14. Caulking by the caulking part 131a is performed to bring the distal ends of the operating parts 14, 14 into close contact with the sliding member 133 at the journal part 13. |
