Abstract: A linear transmission device with capability of wireless power supply includes a transmission mechanism and a wireless power supply module. The transmission mechanism includes a long shaft part and a moving part. The long shaft part defines an axis. The moving part is disposed on the long shaft part in a manner that the moving part is movable along the axis. The wireless power supply module includes a magnet-providing part disposed on the long shaft part for providing a magnetic field and an induction coil disposed on the moving part. A direction of the magnetic field is parallel to the axis. A normal vector of the induction coil is parallel to the direction of the magnetic field. When the moving part is moved along the axis, a current is induced in the induction coil through variation of the magnetic field.
