Abstract
The device for providing electric connection between a rotatable member and a stationary member has a doughnut-like housing of an insulating material and an annular and insulating base plate disposed in the housing coaxially and movably both in the circumferential and axial directions. Two annular contact plates are placed on a front face of the base plate, and two contact pins are held in the housing and urged always to stand on the contact plates, respectively, by means of compression springs. Both the housing and the base plate are locally shaped such that one of them can be fixed to the rotational member while the other can be engaged with the stationary member so as to be restrained from rotating together with the former.
