Abstract
In an in-tank type motor-operated pump having a brush motor (1), a bearing (15) for rotatably holding a rotor shaft (5) is covered with a heat resistant insulating material (25) and is mounted in a bracket (22) in which brushes (4) are slidably held, thereby preventing an accidental shortcircuit between brushes (4) via the bearing (15) at the time when the bracket (22) melts with heat.
