<P>PROBLEM TO BE SOLVED: To provide a detachable coupling which facilitates attachment and detachment of a mixing shaft to and from a rotation driving part, has not such a risk that the mixing shaft falls off from the rotation driving part and is suitable for frequently attaching and detaching the mixing shaft to and from the rotation driving part, in an agitation device having such a structure that the mixing shaft can be freely engaged and disengaged with the rotation driving part. <P>SOLUTION: The detachable coupling comprises: a locking protrusion 1d disposed so as to protrude toward the lateral side on the root part 1b of the mixing shaft 1; a coupling-receiving part 3a with which the mixing shaft 1 is engaged; a shaft-direction slit 3b to which the locking protrusion 1d can be inserted; a locking recessed part 3c orthogonal to the shaft-direction slit 3b; and a regulating protrusion 4b which can be moved while being engaged with the interior of the shaft-direction slit 3b on the inner circumferential part of a slide cover 4 slidably disposed on the outer circumferential part of the coupling receiving part 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
