Abstract: An air cleaner not susceptible to a decrease in effect. The air cleaner includes: a storage tank that stores a liquid; and an air blowing unit. In the air cleaner, the storage tank has an air receiving region and a dust retention region formed therein, and the air blowing unit blows air to the air receiving region. The dust retention region is a region partitioned by a wall in which an opening is formed toward an upstream side of a flow of the liquid.

Abstract: A strap that prevents handles from slipping down from the shoulder. The strap is capable of being hooked, from the front side and the back side of a user, on the handles of a bag hung over the shoulder by passing under the armpit on a side opposite to the side where the handles are. Preferably, the strap has a first engagement portion provided on at least one end portion and a second engagement portion provided at a location different from the first engagement portion and capable of engaging with the first engagement portion, and the handles pass through the inner sides of rings formed by engagement between the first engagement portion and the second engagement portion, and thereby the strap is capable of being hooked on the handles.
