A motor which can be mounted in an endoscope probe without bending an electric power supply wire in an endoscope probe body, and an endoscope probe using the motor are provided. The motor includes a magnet, a field coil, a housing, an electric power supply wire, and a shaft. A lead wire from the field coil is connected to the electric power supply wire. A cutout is provided in a housing end, and the electric power supply wire is received along the cutout and led out to the outside of the motor in the direction in which a shaft projects. When the motor is mounted in the endoscope probe, the motor is placed in the endoscope probe body so that the shaft projects in the direction opposite to the direction of the front end of the endoscope probe, and the electric power supply wire, which is led out to the outside of the motor, is routed along the longitudinal direction of the endoscope probe.

Motor and endoscope probe equipped with motor

In order to improve the reliability of an electrical connection between a power supply terminal of a vibrator and an electrode of a circuit board and to improve the efficiency of mounting the vibrator on the circuit board, the power supply terminal is made from a torsion coil spring and a contact portion of the power supply terminal in contact with the electrode of the circuit board is formed by winding. In addition, a torsion coil spring portion is wound around a spindle pin and a housing is provided with a step portion as a space for accommodating the contact portion without interference and a plane portion to which the contact portion faces. Moreover, a partition plate is provided between a pair of power supply terminals or a space where the contact portion can be elastically deformed is surrounded by a box member, a pair of power supply terminals having positive and negative polarities are extended in a bilaterally symmetric direction from torsion coil spring portions to the contact portions, and the power supply terminals are constructed so as to be elastically deformed to allow each contact portion to reach the outside of each torsion coil spring portion.
