PURPOSE: To compact the device by connecting an airforce pump driven by an electric motor to a pressure box. CONSTITUTION: An adjust drive device of electric-drive type consists of an airforce pump 2 driven by an electric motor 1, and a pressure box 3 having a linear relation with the adjust force and retaining force, and the suction pressure. In this way, it is possible to drive with relatively low power and control the adjust force and retaining force simply and correctly, therefore it is possible to form the whole device in a compact way. |
