wherein:
the terminal block has an engagement hole that receives an engagement part of the terminal such that a gap is between an inner peripheral surface of the engagement hole and an outer peripheral surface of the engagement part; and
the engagement hole and the engagement part are configured such that the engagement part can move relative to the engagement hole in all directions perpendicular to a longitudinal axis of the engagement hole due to the gap.
