<P>PROBLEM TO BE SOLVED: To provide a constitution capable of suppressing lubricant of a worm gear part from coming into the inside of a motor in an opening/closing device of the lid of a toilet or a toilet seat having a structure in which a worm gear is mounted on the rotary shaft of the motor. <P>SOLUTION: In the structure in which the worm gear 112 is mounted on the rotary shaft of the motor 111 for rotating a lid driving shaft 110 for driving the lid of the toilet, the worm gear 112 and the motor 111 are inclinedly arranged such that the side of the worm gear 112 is located under the motor. The intrusion of the lubricant into the motor 111 is suppressed because the lubricant does not move to the side of the motor 111 located in an upper side even though the lubricant sticking to the worm gear 112 moves by the action of gravity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
