CONNECTION STRUCTURE AND CONNECTION METHOD

摘要

This connection structure is configured in such manner that: the base end of an electrode section 12 has a bar-like shape; one end side of a connection member 14 is provided with an electrode insertion section 14b into which a bar-like electrode section 12a can be inserted; the other end side of the connection member 14 is provided with a wire insertion section 14c into which an operating wire 13 can be inserted; the bar-like electrode section 12a and the connection member 14 are joined by plastically deforming and staking at least a part of the peripheral wall of the electrode insertion section 14b while the bar-like electrode section 12a is inserted in the electrode insertion section 14b; the operating wire 13 and the connection member 14 are joined by plastically deforming and staking at least a part of the peripheral wall of the wire insertion section 14c while the operating wire 13 is inserted in the wire insertion section 14c; and the strength of joining between the bar-like electrode section 12a and the connection member 14 is higher than the strength of joining between the operating wire 13 and the connection member 14.
