Abstract:
Press-fitting the bus-bar into the connection terminal while improving reliability.
In the rotary electric machine, the connection terminal comprises a terminal fixing portion fixed to the circuit board and held by the terminal holder, and a terminal connection portion arranged on the other side in the first direction with respect to the terminal fixing portion and for press-fitting the bus-bar. The terminal connection portion is arranged separately from the circuit board on the lower side. In the connection terminal, the connecting portion connecting the terminal fixing portion and the terminal connection portion is configured to be bendable and deformable vertically. This allows the terminal connection portion to be displaced when a press-fitting load above predetermined value is input to the terminal connection portion. Thus, since the press-fitting load is used as a load that bends and deforms the connecting portion, the load transmitted to the terminal fixing portion is reducible.
