A tube joining device that fuses an end of a first tube and an end of a second tube in an aseptic condition, comprising:
- a plate-shaped cutting member;
- means for heating said cutting member;
- a first tube holding portion that is capable of holding a first tube on a first side of the cutting member;
- a second tube holding portion that is capable of holding a second tube on a second side of the cutting member;
- a tube superimposing portion that causes the first tube holding portion and the second tube holding portion to approach each other to dispose the first tube and the second tube in a superimposed manner;
- and
- a switching mechanism that is capable of switching the second tube holding portion from a state in which the second tube is held to a state in which the second tube is released,
- wherein the switching mechanism applies a first biasing force for maintaining the state in which the second tube is held, and applies a second biasing force for maintaining the state in which the second tube is released, the second biasing force being applied when the first tube holding portion and the second tube holding portion approach each other.
