Claims

[Scope of utility model registration request]

In a structure in which the spring constant of a boat support spring of a current collector for an electric vehicle is made variable, one end of the leaf spring is attached to a support fitting connected to a framework, etc., and the other end is fixed to the current collector boat, A restraining metal fitting having a drive mechanism that engages both sides from the left and right in the intermediate portion of the leaf spring and restrains the movement of the leaf spring is disposed, and a movable rod is connected to the restraining metal fitting to arbitrarily control the restraining position of the leaf spring. 1. A spring structure for a current collector, characterized in that the spring constant of the leaf spring can be changed steplessly by attaching a drive mechanism to the support fitting that allows selection of the following.
