APPARATUS FOR OPENING AND CLOSING A DOOR OF A CONTAINER APPARATUS OF A VEHICLE

An opening and closing device for a door of a container unit in a vehicle is provided to enhance the outer appearance of the container units while increasing user convenience by installing a single knob for opening or closing the door of the container unit rather than two knobs as in a conventional method. An opening and closing device for a door of a container unit includes a knob(11), a shaft(12), a fixed member, a shaft biasing spring(20), an arm(18), and a cam(19). The shaft is capable of shifting in the axial direction, and has a radial extension portion(12c) extending in the radial direction, first to third rotational positions in the rotational direction of the shaft, wherein the first and the third rotational positions are offset by 180 degrees. The arm has an opening side arm(18a) corresponding to the first rotational position of the shaft, and a closing side arm(18b) corresponding to the third rotational position of the shaft. A cam driving protrusion(18h) for driving the cam is formed on at least one of the opening arm and the closing arm. A support member having an opening side support member(15a) and a closing side support member(15b) can be installed at the arm, wherein both the opening side support member and the closing side support member have relief portions for preventing the radial extension portion of the shaft from contacting the opening and the closing side support members when the shaft rotates from the second rotational position to the third rotational position.
