Claim:
A terminal connection structure, comprising: a printed board having a terminal hole and conductor; an insulation plate having a terminal through-hole; and a terminal that is inserted, in an insertion direction, via the terminal through-hole in the insulation plate into the terminal hole, a given clearance being provided between an inner surface of the terminal through-hole and a whole peripheral surface of the terminal, and the terminal through-hole including, on opposing portions of the inner surface, protrusions for correction of alignment of the terminal; the terminal being provided with bulged portion that protrude from the terminal in a direction perpendicular to the direction of insertion and are sized and positioned to be capable of engagement with the protrusions for correction of alignment; wherein, in a final, assembled state of the terminal connection structure, the bulged portions do not engage the protrusions for correction of alignment, the given clearance exists between the inner surface of the terminal through-hole and the whole peripheral surface of the terminal, and an end of the terminal is soldered to the conductor.
