ことができる。 The present invention is as described above, and in particular, an upper case that rotatably supports a rotor shaft having a power generation coil;
A resin lower case that covers the lower opening of the upper case and is equipped with a power supply push terminal, a current collector plate that connects one end of the generator coil and rotates together with the rotor shaft, and Since the metal elastic plate has one portion pressed against the current collector plate and the other portion used as a pressing biasing portion of the push terminal, the pressing slide of the current collection mechanism can be controlled by only this metal elastic plate. The pressing part of the contact part and the push terminal can be achieved, and therefore many separate parts are required, such as the push terminal urging spring, the current collection mechanism urging spring, and the nut that attaches them, as in the past. This reduces the number of parts used and contributes to lower manufacturing costs. Furthermore, since the center of this metallic elastic plate is fixed, the pressing force on the current collector plate changes depending on the thickness of the lead wire held by the push terminal, etc., and the urging force of the pressing urging part changes. Therefore, even if the current collector plate rotates with the rotation of the rotor shaft, the elastic plate will not wear out excessively, and the generated power can be stably extracted over a long period of time.
また前記プツシユ端子と金属性弾性板とを一体
化すれば、さらに部品点数の低減化が計れ、製造
費用をより一層低減できるものである。 Further, by integrating the push terminal and the metallic elastic plate, the number of parts can be further reduced, and manufacturing costs can be further reduced.
