A self-propelled vacuum 1 includes a vacuum body 2, a suction unit 5 for sucking dust and the like on a floor surface F, a traveling drive unit 4 configured to drive wheels 21, a front sensor 51 configured to sense an obstacle S in the front in a traveling direction, and a vehicle height adjustment unit 6 configured to move the wheels 21 up and down to adjust the vehicle height of the vacuum body 2. In a case where the traveling drive unit 4 is driven and the front sensor 51 senses the obstacle S during self-propelling, the vehicle height adjustment unit 6 increases the vehicle height to a predetermined height, and thereafter, the self-propelled vacuum 1 moves over the obstacle S while the vehicle height is being adjusted such that a distance to the obstacle S is held within a predetermined range.

Abstract: An object is to provide a sash coupling structure and a method for sash coupling that ensures omission of the process. The sash coupling structure is made such that on a door frame constituted of a column and an upper sash, a coupling cross-sectional surface of the column and a coupling cross-sectional surface of the upper sash are butted together. The column is constituted of a channel member and an inner member. The channel member and the inner member include adhering portions coupled one another along a longitudinal direction. The inner member is plated. A non-adhering portion, which faces a non-not-yet-adhering portion of the inner member, is formed on the channel member at a butted coupling portion.
