an operation portion including a dispensing member, the dispensing member extending in an up-down direction and being provided with a spiral groove;
a sleeve surrounding an outside of the dispensing member and provided so as to be rotatable on an axis line of the dispensing member;
a middle plate body holding contents and provided inside the sleeve so as to be movable in the up-down direction in a state where rotation of the middle plate body on the axis line relative to the sleeve is restricted; and
a movable shaft extending downward from the middle plate body and including an engagement protrusion that engages with the spiral groove, wherein
a sliding portion, which is formed of a softer material than either one member of the sleeve and the operation portion and on which the other member of the sleeve and the operation portion slides as the sleeve and the operation portion rotate relative to each other, is fixed to the one member,
the operation portion is provided with a circumferential groove, the circumferential groove opening outward in a radial direction and extending on an entire circumference around the axis line,
the sleeve is provided with a protrusion, the protrusion protruding inward in the radial direction and being accommodated in the circumferential groove,
the sliding portion is integrally fixed to an inner surface of the circumferential groove, and
the protrusion moves inside the circumferential groove while sliding on the sliding portion as the sleeve rotates on the axis line.
