Claims

[Claims for Utility Model Registration] A rotating shaft of a motor that can be reciprocated, a housing for a motor that supports the rotating shaft, a worm provided on a part of the rotating shaft,
A worm wheel that engages with the worm and is driven by power from the rotating shaft, and a thrust bearing that comes into contact with the tip of the rotating shaft and receives the thrust load of the rotating shaft, the tip of the rotating shaft has a tip protrusion that abuts the thrust bearing with little friction, and the thrust bearing includes a metal plate that comes into contact with the tip protrusion of the rotating shaft; Relative rotation occurs between a recess formed in the housing of the motor so that the motor is accommodated, and the metal plate on the side opposite to the rotation shaft so that the metal plate is pressed against the protrusion at the tip of the rotation shaft. A shaft support device for a worm speed reducer, comprising a synthetic resin part that is in close contact with the housing of the motor and is injection molded within a recess of the housing of the motor.
