A rotary feedthrough according to the disclosure includes: a seal partition wall dividing a space into a first space and a second space; a rotating member positioned to extend through the seal partition wall and configured to transmit a rotational driving force; a rotation input unit positioned in the first space and configured to input a driving force to the rotating member; and a rotation restraining unit positioned in the second space and configured to restrain rotation of the rotating member. The rotation restraining unit restrains rotation of the rotating member about a rotation axis exceeding a predetermined rotation angle.

SPEED REDUCER, DRIVING DEVICE, AND CONSTRUCTION MACHINE
A speed reducer 10 of one embodiment comprises: a carrier 11; a first case 20 that surrounds an outer peripheral surface of the carrier 11 located between both end surfaces of the carrier 11, and is relatively rotatably held by the carrier 11 between the both end surfaces of the carrier 11; a second case 30 that surrounds the outer peripheral surface of the carrier 11, and is relatively rotatably held by the carrier 11 at a position different from the position at which the first case 20 is held between the both end surfaces of the carrier 11; a first reduction part 40 including a first input part which is held by the carrier 11 and to which a rotation is input from a first side FS facing one of the both end surfaces of the carrier 11; and a second reduction part 50 including a second input part which is held by the carrier 11 and to which a rotation is input from a second side SS facing the other end surface of the both end surfaces of the carrier 11.

An aspect of the present disclosure provides a sealing device including a cylindrical cover having an opening; an output plate fitted onto an inner peripheral surface of the cover; a primary sealing portion providing sealing between the cover and the output plate; and a secondary sealing portion closer to the opening than is the primary sealing portion. The secondary sealing portion is defined at least by the cover and the output plate.
