PROBLEM TO BE SOLVED: To improve the degree of freedom in designing an operation member.SOLUTION: A feeding container 10 includes: a cylindrical operation member 11; a cylindrical container body 12 projecting from the inside of the operation member 11 toward one side along the direction of a container axis O; and a holding member 13 disposed in the container body 12 so as to be movable back and forth along the direction of the container axis O. The container body 12 includes: a base cylinder section 17 disposed in the operation member 11 and regulated in circumferential relative rotation with respect to the operation member 11; and a rotating cylinder section 18 externally mounted to the base cylinder section 17 so as to be circumferentially relatively rotatable. The holding member 13 includes: a body section 26 disposed within the rotating cylinder section 18; and a shaft 27 inserted into the base cylinder section 17. The rotating cylinder section 18 and the body section 26 are provided with engaging units to regulate the circumferential relative rotation of the rotating cylinder section 18 and the holding member 13. One of the inner circumferential surface of the base cylinder section 17 and the outer circumferential surface of the shaft 27 has a helical groove 28 formed therein, and the other having a protrusion 29 to be disposed within the helical groove 28, formed thereon. |
