Abstract: In a hot-water storage type heating unit 1, a liquid-liquid heat exchanger 15, which exchanges heat between a first hot-water circulation circuit 12 through which hot water stored in a hot-water storage tank 11 circulates and a heating circulation circuit 14 in which the hot water flows from a radiator unit 3 for heating, is disposed above the hot-water storage tank 11, and a circulation pump 16 is disposed in the first hot-water circulation circuit 12 on the downstream side of the liquid-liquid heat exchanger 15. In order to return the gas, which is separated by a gas-liquid separator 17 provided so as to be interposed in the first hot-water circulation circuit 12 between the liquid-liquid heat exchanger 15 and the circulation pump 16, to the hot-water storage tank 11, a return passage 18 which communicates between the hot-water storage tank 11 and the gas-liquid separator 17 is provided.

Abstract: In a steering lock device, a lock bar is disposed so as to be offset parallel to a key cylinder along a longitudinal direction of a vehicle (i.e., a central axis of the lock bar and a central axis of the key cylinder are parallel), and is disposed so as to be adjacent to the key cylinder along the central axis of the key cylinder. Further, a proximal end of the lock bar and a rear end of the key cylinder are disposed so as to overlap one another. In accordance with the steering lock device, an amount of projection from a steering column (i.e., a rectilinear distance from an outer peripheral surface of the steering column to a center of a key insertion opening of a key rotor) can be kept small. Degrees of freedom in design of an outer shape of a column cover are thereby increased.
