PROBLEM TO BE SOLVED: To hold a capsule with an ease of handling and high reliability by adding an actuator member which engages with one of paired holding members intermeshing with each other in a direction in which the capsule is tightened by a guide spreading in the direction in which the capsule is tightened and in a direction in which the guide is activated, to a carrier part connected to the rotary part of a mixing device. SOLUTION: A capsule is arranged between two cavities 21 in holding arms 12, 13. A distributing nozzle provided on one of the end parts of the capsule is arranged in a slot 23 opened in one of the holding arms 12, 13. Further, when an actuator disc 11 is rotated against a carrier plate 10, the holding arms 12, 13 assisted by a spring 30 which connects the actuator disc 11 to the sleeve 15 of the carrier plate 10 are activated relatively to each other to fix the introduced capsule in the cavities 21 through engaging one holding member with the other. The holding arms 12, 13 are spread in the radial direction by rotating the actuator disc 11 but are self-locked by the frictional force of the guide slot 23. Thus it is possible to hold the mixing capsule with high reliability through simple handling procedures.
