A motor support apparatus is provided which supports an output shaft of a motor used to operate a pump. The motor support apparatus includes a support housing, a bearing chamber formed in said support housing, a bearing member for bearing an output shaft of a motor. The bearing member is disposed within the bearing chamber with a given clearance between itself and an inner wall of the bearing chamber. A spring is provided so as to produce an eccentric spring load acting on the bearing member so as to decrease the given clearance for retaining the bearing member tightly within the bearing chamber in order to suppress mechanical vibrations generated during a motor operation.
