Hinge device for storage container

摘要

A hinge device coupling a cover to a container body is minimized so as not to project from the container body to achieve a neat appearance, and is simplified to facilitate efficient production and installation. The hinge device includes a housing having a cavity and attached to one of the cover and the container body, a hinge shaft having a cam part rotatably housed in the housing and having a major axis and a minor axis in cross-section, an insert part extended from the cam part to protrude from the housing and connected to the other one of the cover and the container body, and a pair of leaf springs disposed in the housing to press respective outer surfaces of the cam part.
