PROBLEM TO BE SOLVED: To widely improve insertion and extraction by integrating a battery connector with a lock pawl, and providing a spring for ejecting a battery pack on an outer side of a battery connector with respect to the insertion side of the battery pack. SOLUTION: Under a condition where a battery cover unit 24 is locked, an ejection coil spring is in a maximum compression condition. At that time, projective terminal bases 19a, 19c are being inserted into the deepest parts of a recessed minum terminal 15a and a recessed plus terminal 15b of a battery pack 15, respectively, and contact terminals 19b, 19d extend into an umbrella shape with their spring characteristics in each inside. A lock pawl 19g at a tip is in a condition that it is completely fitted in a deepest part lock recess 15e of a slit 15c. Accordingly, when the pack 15 tends to move in the direction away from a battery connector 19, it never moves due to a lock protrusion 15d as well as a guide rib 17b held together with a base plate 18 and provided at a rear face of a tip of a lock arm 19f.
