Abstract
A roller shutter type storage container includes a container body, a roller shutter accommodating portion, a pair of guide grooves, and a roller shutter. Each of the guide grooves extends linearly in an opening of the container body and is curved in the roller shutter accommodating portion. The roller shutter is configured by connecting a plurality of slats each having shafts formed in the widthwise direction at two ends of the slat in a bendable manner. As the two shafts slide in the corresponding guide grooves, the roller shutter slides between an open position and a close position. Each one of the shafts is spaced from a vertical wall surface of the corresponding one of the guide grooves. A projection formed of soft material projects outward from each shaft of each slat in the widthwise direction and contacts the corresponding vertical wall surface in an elastically deformed state.
