A container holding unit includes an abutting portion and an urging device for urging the abutting portion to a circumference of a container to constrain the container. The container holding unit further includes a case having a first guide grove and a second guide grove extending downwardly. The abutting portion includes a first shaft inserted in the first guide grove and a second shaft inserted in the second guide grove, so that the abutting portion slides relative to the case. The abutting portion is rotatable in a direction that a projecting amount of the abutting portion from the case decreases when an upward force is applied from below. The urging device urges the abutting portion in a direction that the abutting portion projects from the case, and in a direction that the abutting portion returns to an initial position.
