An activating device activates a cover (15) for the opening face (14a) of a container (14). Pivot arms (16) are fixed to a pivot unit (17) equipped with an electric motor through a reduction gear at one ends, and fixed to plate springs (18) at the other ends (16b). One end portions (18a) of the plate springs (18) are fixed to the respective front and rear portions of the cover (15), the other end portions thereof are fixed to the other ends (16b) of the pivot arms (16). The resiliency of the plate spring (18) is set lower in the vertical direction of the container (14). The plate spring (18) is bent from its other end portion toward its one end portion (18a) at substantially 90 DEG or larger of bending angle. The plate spring (18) is formed so that it bends toward the inside of the center of the cover (15) between the pivot arm and the cover. <IMAGE> |
