[Problem] To provide a terminal connection structure that can reliably connect terminals together even if the positional offset between the terminals is great.[Solution] The terminal connection structure connects a busbar and a first terminal connected to the coil of a motor. The terminal connection structure is provided with: a base having a bottom wall; a terminal holder that can hold the first terminal and the busbar in an overlapping state; and a mobile attachment section. The mobile attachment section has: a bottom plate section that is provided to the terminal holder and that is parallel to the bottom wall; and a holding slit that is provided to the base, is entered by the bottom plate section, and is larger than the bottom plate section. The mobile attachment section attaches the terminal holder to the base movably in parallel to the surface of the bottom wall.
