<p>A hinge device is provided to rotatably connect a first member and a second member. In the hinge device, a pin hole with a first polygonal cross-section is defined in one of the first and the second members, and a hinge pin has a second polygonal cross-section, one end portion, and the other end portion. The second polygonal cross-section is different from the first polygonal cross- section, the one end portion is fixed to the other of the first and the second members, and the other end portion is inserted in the pin hole. Therefore, when one of the first and the second members is rotated, the other end portion of the hinge pin is elastically deformed by the inner wall of the pin hole to allow a relative rotation between the pin hole and the hinge pin at regular angle intervals.</p> |
