The lock unit includes a latch plate, and the electric closing unit includes a support base, a striker base pivotally connected through a pivot pin to the support base, a striker formed on the striker base and engageable with the latch plate, and an electric power mechanism for pivoting the striker base between uppermost and lowermost positions by an electric power. A leading edge of the striker is inclined relative to an imaginary plane over which the striker base turns about the pivot pin.
