The present invention independently inhibits rotation of an axial-fitting-type rotary shaft during non-mounting to a base. A tablet cassette 40 is provided with: an oscillation fulcrum 53 for supporting an oscillating member 70 in a slit 52 formed in a bottomed hole 17a of a hollow rotary shaft 17； a locked part 60 for encircling the rotary shaft 17, the locked part 60 being provided to a bottom plate part 12 of a container lower part 13 and being separated from the hollow rotary shaft 17； an oscillating member 70 in which a passive part 71 and a locking part 72 are divided on both sides of the oscillation fulcrum 53； and an urging member 80 for causing the locking part 72 to face the locked part 60 and causing a passive end part 71 to advance into the bottomed hole. In a free state of detachment from a base 20, a locking end part 72 comes in contact with the locked part 60 and is locked, and when a drive shaft 24 is mounted to the base 20 and fitted in the bottomed hole 17a, the passive part 71 is pushed out from the bottomed hole 17a and the locking part 72 withdraws from the locked part 60.
