Claim of US Patent No. 9,895,815

1. A manufacturing process for manufacturing a multiple joint robot,
the multiple joint robot comprising:
a movable body;
a motor for generating power to actuate the movable body;
a motor housing accommodating the motor in an interior of the motor housing so as to isolate the motor from an exterior; and
a heat conductor situated in the interior of the motor housing and forming a heat conducting path for conducting heat from
the motor to the motor housing,

the manufacturing process comprising:
sliding at least one of a first contact surface and a second contact surface of the heat conductor on an opposed heat generating
surface on a side of a motor body or an opposed inner surface of the motor housing, such that the first contact surface of
the heat conductor comes in contact with the heat generating surface and the second contact surface of the heat conductor
comes in contact with the inner surface of the motor housing, so as to adjust a position of the heat conductor; and

thereafter fixing the heat conductor by a fixture so as to form the heat conducting path.
