Claim:
An emblem-unified trunk opening and closing device comprising: a housing including an inner case and an outer case; a knob including an emblem configured to be pushed and restored with respect to the outer case outside the housing; a connector which is provided at a front end of the inner case and to which a terminal which electrically contacts an outer electric source is set; a printed circuit board which is disposed inside the inner case to be supported and is formed to be able to electrically contact the terminal; and a contact unit arranged in the inner case, the contact unit being selectively in contact with the printed circuit board in response to a push operation of the emblem so as to apply an electric current to the terminal of the connector thereby opening a trunk; wherein the contact unit comprises: an upper guide coupled to the emblem; a rubber cap, a lower portion of which being coupled to an upper portion of the connector and an upper portion of which being in surface-contact with the upper guide; a lower guide coupled to the rubber cap via an upper portion thereof; a tact switch being provided with an electricity applying portion being in surface-contact with a lower portion of the lower guide to be elastically pushed by the lower guide to contact the printed circuit board; wherein the upper guide and the lower guide are reciprocated in the inner case by external force applied to the upper guide and elastic force of the rubber cap; and wherein the lower portion of the lower guide has a cone shape, and the electricity applying portion of the tact switch is co-axially disposed with the cone shaped lower portion of the lower guide to allow pushing force to be concentrated onto the electivity applying portion.
