Claims (1)

[Scope of utility model registration request] A joint member having a fitting and fixing part on one side for fitting onto a rotational drive shaft, and a fitting part on the other side for fitting with a connecting shaft of a flexible shaft described later, and a fitting part of the joint member having a fitting part on one side that is rotatable on one side. A sphere having a diameter slightly larger than the thickness of the peripheral wall is loosely fitted into a through hole bored in the peripheral wall of the connecting cylinder, and the connecting cylinder is fitted externally into the connecting cylinder. The sliding ring, which can be slid in a certain range in the axial direction, elastically contacts one end of the sliding area by a spring to close the through hole, while the sliding ring is inserted from the other side of the connecting cylinder. The outer surface of a bearing cylinder provided at the other end of a flexible shaft having stirring blades at one end accommodates a portion of the sphere that protrudes from the peripheral surface of the connecting cylinder when the sliding ring covers the through hole. When the bearing sleeve of the flexible shaft is fitted into the connecting tube and the sphere is housed in the recess, the connection shaft of the flexible shaft, which is rotatably supported by the bearing tube and has a non-circular cross section, is formed. A stirrer having a joint that can be easily attached and detached, characterized in that it is configured to fit into a fitting portion of the joint member.
