Abstract
In a motor driven device, a yoke of a motor has a flange at a side of its opening. An end plate sized smaller than the flange is formed with tongues on its outer circumferential periphery so that the end plate is press-fit in position in the yoke through the tongues. An annular packing is disposed around an annular ring part of the end plate so that the packing encircles the end plate when the flange of the yoke is fixed to a housing of a pump. The packing fluid-tightly seals the inside of the yoke from an outside.
