To provide a tilt hinge in which dispersion of running torque to generate is reduced and some component parts are eliminated to lower the production cost.

In a non-step tilt hinge of a curl type compring a fit-up member having a curl part, a shaft which is force-fitted to the curl part of the fit-up member and is rotatable relatively against the fit-up member, and a bracket mounted on the shaft, a flat part is formed at least in a part of the inside of the curl part which is made press-contact with the axial portion of the shaft to specify the portion for creation of a friction torque.
