Abstract

A motor includes a stator with a bobbin. The bobbin has a lower end winding portion, a head part retainer portion that retains a head part of a winding, and a control portion disposed between the lower end winding portion and the head part retainer portion. A head part retainer surface formed on a pump part side of the head part retainer portion and an end face formed on a pump part side of the control portion are positioned on the same plane and on a pump part side relative to a winding retainer surface that is formed on a pump part side of the lower end winding portion. Thus, when the winding is wound in layers onto the winding retainer surface of the bobbin, collapsing of a middle part of the winding onto the head part of the winding is prevented.
