A conveyor apparatus for conveying articles, comprising: a plurality of traveling units that travel in series along a conveying path for the articles; and a plurality of article supports that have article support surfaces for supporting the articles and that are caused to travel on the conveying path by the respective traveling units, the conveyor apparatus further comprising infilling members provided for the respective article supports, the infilling member filling a clearance between the article supports longitudinally adjacent to each other in the conveying path, the article support including a support contact part on a rear end of the article support along the conveying path, the infilling member including an infilling contact part on a front end of the infilling member along the conveying path, the infilling contact part being in contact with the support contact part, characterized in that the infilling contact part has a larger curvature than the support contact part so the ends of the plate contact part in the width direction come into contact with the underside of the support contact part, vertically leaving no clearance on the ends in the width direction, and the conveyor apparatus comprises an urging member that urges the infilling contact part of the infilling member to the support contact part of the article support, wherein the infilling contact part is made of a flexible material, and the infilling contact part is urged to the support contact part by the urging member so as to come into contact with the support contact part while being bent along a shape of the support contact part, so that even if the infilling contact part and the support contact part have different shapes because of the difference in curvature between the infilling contact part and the support contact part, the urging member urges the infilling contact part to the support contact part so as to shape the infilling contact part along the support contact part, thereby completely filling a clearance between the infilling contact part and the support contact part. the conveyor apparatus further comprising infilling members provided for the respective article supports, the infilling member filling a clearance between the article supports longitudinally adjacent to each other in the conveying path, the article support including a support contact part on a rear end of the article support along the conveying path, the infilling member including an infilling contact part on a front end of the infilling member along the conveying path, the infilling contact part being in contact with the support contact part, characterized in that the infilling contact part has a larger curvature than the support contact part so the ends of the plate contact part in the width direction come into contact with the underside of the support contact part, vertically leaving no clearance on the ends in the width direction, and the conveyor apparatus comprises an urging member that urges the infilling contact part of the infilling member to the support contact part of the article support, wherein the infilling contact part is made of a flexible material, and the infilling contact part is urged to the support contact part by the urging member so as to come into contact with the support contact part while being bent along a shape of the support contact part, so that even if the infilling contact part and the support contact part have different shapes because of the difference in curvature between the infilling contact part and the support contact part, the urging member urges the infilling contact part to the support contact part so as to shape the infilling contact part along the support contact part, thereby completely filling a clearance between the infilling contact part and the support contact part.
