PROBLEM TO BE SOLVED: To provide a mixer convenient for maintenance and for which belt- replacing work can easily and quickly be carried out in the case a belt is broken. SOLUTION: A rotation table 10 is attached to an upper end of a main axis 9 rotating on a first axial line L1 and a mixing container 12 is attached to the rotation table 10 as to be freely rotated on a second axial line L2 and at the same time, a rotation mechanism 20 for making the mixing container 12 rotate on its own axis following the rotation of the main axis 9 is installed. A first pulley 21 in the self-rotating mechanism 20, a second pulley 22 formed in the mixing container 12, and a belt 23 wound round both pulleys are installed on the upper face of the rotation table 10, so that the belt 23 can be replaced with a new one on the upper face side of the rotation table 10 when the belt is broken.
