  • Patent number: 12072017
    Abstract: A motor unit for transmitting a driving force of a motor driven by a battery to an opening and closing mechanism through a worm gear and a worm wheel includes lubricating grease. The grease includes a solid additive that increases a friction coefficient between the worm gear and the worm wheel as its addition amount increases. The addition amount is not less than a first threshold and is not more than a second threshold. The first threshold is an addition amount for realizing a friction coefficient at which transmission efficiency from the worm wheel to the worm gear becomes 0 [%]. The second threshold is an addition amount for realizing a friction coefficient at which a starting voltage of the motor to move the opening and closing mechanism in an opening direction becomes a minimum guaranteed voltage of the battery after the opening and closing mechanism is restrained fully closed.
