Motor

Abstract

A motor may include a coil bobbin having a drum part around which a winding is provided, a terminal block formed on an outer periphery of the coil bobbin, at least a pair of terminal pins which are protruded from a first wall face of the terminal block, and a groove part formed in the first wall face of the terminal block and is opened to a second wall face of the terminal block that is perpendicular to the first wall face. Both ends of the winding are respectively bound to a pair of the terminal pins from the second wall face side through the groove part of the terminal block. A stator core may be utilized instead of the coil bobbin. In this case, the terminal block may be fitted to the stator core.
