The present invention inhibits rotation of a rotary shaft of an axial fitting type independently when a tablet cassette is not mounted to a base. A tablet cassette 40 includes: support points of swing motion 53 configured to support a swing member 70 in a slit 52 formed in a bottomed hole 17a of a hollow rotary shaft 17； an engaged portion 60 provided on a bottom wall portion 12 of a lower portion 13 of a container and spaced from the hollow rotary shaft 17 to surround the rotary shaft 17； a swing member 70 having a follower portion 71 and an engaging portion 72 located on different sides of the support points of swing motion 53； and an urging member 80 operable to move the engaging portion 72 toward the engaged portion 60 and move the follower portion 71 into the bottomed hole. In a free state in which the tablet cassette is detached from the base 20, the engaging portion 72 abuts against and engages with the engaged portion 60. When the tablet cassette is mounted to the base 20 and the drive shaft 24 is fitted into the bottomed hole 17a, the follower portion 71 is pushed out of the bottomed hole 17a, and the engaging portion 72 is disengaged from the engaged portion 60.
