Claims

[Claims for Utility Model Registration] (1) A current-carrying bearing in which a spring is slidably connected between an end of the inner circumferential surface of an outer ring and an end of the outer circumferential surface of the inner ring facing the end, the spring having a shape of a spiral wire. A current-carrying bearing characterized by being a helical spring whose parts are symmetrically connected smoothly. (2) Registration of a utility model characterized in that the shape of the helical spring is one in which a portion of a spiral line is symmetrically connected to a portion of each circle with the same radius centered on two adjacent points. A current-carrying bearing according to claim 1. (3) In a current-carrying bearing in which a spring is slidably connected between the end of the inner peripheral surface of the outer ring and the end of the outer peripheral surface of the inner ring facing the end, the shape of the spring is a helical spring that is part of a spiral wire. A current-carrying bearing featuring: (4) The current-carrying bearing according to claim 3, wherein the spiral spring has a shape in which a part of a spiral line is smoothly connected to a part of a circle.
