A rotating cylinder part, and the holding member projects from the main body part disposed in the rotating cylinder part and on the other side along the container axial direction from the main body part, and is inserted into the base cylinder part. A shaft portion, and the rotary cylinder portion and the main body portion engage with each other. An engaging portion for restricting relative rotation of the rotating tube portion and the holding member in the circumferential direction is provided, and is provided on either the inner peripheral surface of the base tube portion or the outer peripheral surface of the shaft portion. Is formed with a spiral groove extending in the circumferential direction, and a projection portion disposed in the spiral groove is formed on one of the other, and the end portion on the other side is formed on the rotating cylinder portion. A barrel portion that is disposed in the operation member and is rotatably fitted to the base tube portion, and extends from the barrel portion to the other side and has a larger diameter than an end portion on the other side of the barrel portion. And a leg portion provided with an annular gap between the base tube portion, and a portion of the base tube portion located on the other side of the body portion includes the base tube portion and A ring member whose relative rotation in the circumferential direction is restricted is fitted on the ring member, and the ring member is disposed in the annular gap.
