Abstract:
A connecting structure for medical use includes a male assembly 1 and a female connector 2. The male assembly 1 includes a male connector 10 and a threadedly engageable cylinder 20. A male luer portion 11 of the male connector 10 and a female luer portion 2a of the female connector 2 are joined by turning the threadedly engageable cylinder 20 in a tightening direction in a state where a female screw 21a of the threadedly engageable cylinder 20 and an engageable protrusion 2c of the female connector 2 are threadedly engaged with each other. A torque limiting mechanism 50 is disposed between an operation cylinder 30 mounted on an outer periphery of the threadedly engageable cylinder 20 and the threadedly engageable cylinder 20. Engageable teeth 51 are formed in an inner periphery of one end portion of the operation cylinder 30 over an entire periphery. A slit 54 is formed in one end portion of the threadedly engageable cylinder 20. The slit is composed only of a straight portion extending from an end of the threadedly engageable cylinder in an axial direction. An area adjacent to the slit 54 is provided as an elastically deformable portion 52. A first engageable claw 53 engageable with the engageable teeth 51 is formed in the elastically deformable portion 52.
