Abstract: A window regulator has a separation inhibiting portion that inhibits separation of first and second arm portions forming an equalizer arm, which is formed of a hole formed to penetrate through the second arm portion and a rising wall portion (convex portion) formed in the first arm portion, a part of which protruding to an outside from the hole of the second arm portion when inserted into a hole of the lift arm and the hole of the second arm portion is caulked so as to come into contact with a rim of the hole of the second arm portion, and a rotation inhibiting portion that inhibits relative rotations of the first and second arm portions, which is formed of a hole (concave portion) formed in the first arm portion and a notch portion caulked so as to engage with the hole of the second arm portion.

Abstract: A method for joining a holed member, including a through-hole, and an unholed member together, the method includes deforming the unholed member against the through-hole of the holed member so that a flat portion of the holed member around the through-hole is deformed into the shape of a truncated conical projection and so that the unholed member is deformed along the truncated conical projection to partly project from the through-hole, and deforming a portion of the unholed member which projects from the through-hole to come into intimate contact with a wall surface of the through-hole of the holed member.
