Title:
TUBE PUMP
Document Type and Number:
Japanese Patent JP2017066969
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a tube pump having a simple configuration capable of restricting positively an occurrence of force for pulling the tube.SOLUTION: In a tube pump 1, when a rotor driving device 8 rotates an eccentric rotor 7 around a first axis line L5, the eccentric rotor 7 moves a pressing member 6 around the first axis line L5 to move a pressing position of the pressing member 6 in respect to a tube 9 supported at a supporting body 2. The pressing member 6 is provided with a first gear part 67 around a second axis line L6 that is a central axis line of the pressing member 6. A holder 5 in the supporting body 2 is provided with a second gear part 27 engaged with the first gear part 67 around the first axis line L5, and then an angular position restricting mechanism 10 for restricting an angular position of the pressing member 6 around the second axis line L6 is constituted by these gear parts. Accordingly, it is possible to set a synchronous relation between a rotation of the pressing member 6 around the second axis line L6 and a rotation of the pressing member 6 around the first axis line L5.SELECTED DRAWING: Figure 2
