An article transporting device comprising: a reciprocating movable body configured to move in forward and backward directions along a travel path having two ends and extending between a non-operator's transfer location at one of said two ends and an operator's transfer location at the other of said two ends to and from which an article is transferred by an operator; a cover body which partially covers an area above the reciprocating movable body which travels over an entire length of the travel path, the cover body having a slit formed therein; and an article support for supporting an article and connected to the reciprocating movable body by a connecting portion (25a, 29) which extends upwardly from the reciprocating movable body and vertically through the slit, the article support being configured to move above the cover body along a direction of the travel path as the reciprocating movable body moves in the forward and backward directions along the travel path; wherein the slit is formed such that the connecting portion (25a, 29) remains out of contact with the cover body when the reciprocating movable body moves along the travel path, and wherein a flexible and elastic cover portion which can be elastically deformed is provided in an end forming portion of the cover body which forms an end of the slit on a side of the operator's transfer location, characterized in that a portion of the end forming portion consists of the elastic cover portion, and the elastic cover portion consists of a plate-shaped resilient member in which a cut-out portion defining the end of the slit on the side of the operator's transfer location is formed. a reciprocating movable body configured to move in forward and backward directions along a travel path having two ends and extending between a non-operator's transfer location at one of said two ends and an operator's transfer location at the other of said two ends to and from which an article is transferred by an operator; a cover body which partially covers an area above the reciprocating movable body which travels over an entire length of the travel path, the cover body having a slit formed therein; and an article support for supporting an article and connected to the reciprocating movable body by a connecting portion (25a, 29) which extends upwardly from the reciprocating movable body and vertically through the slit, the article support being configured to move above the cover body along a direction of the travel path as the reciprocating movable body moves in the forward and backward directions along the travel path; wherein the slit is formed such that the connecting portion (25a, 29) remains out of contact with the cover body when the reciprocating movable body moves along the travel path, and wherein a flexible and elastic cover portion which can be elastically deformed is provided in an end forming portion of the cover body which forms an end of the slit on a side of the operator's transfer location, characterized in that a portion of the end forming portion consists of the elastic cover portion, and the elastic cover portion consists of a plate-shaped resilient member in which a cut-out portion defining the end of the slit on the side of the operator's transfer location is formed.
