To provide a device for coupling dryers, with which two dryers are held by only one user to blow and dry hair, much air is blown in the same direction to quickly dry water on the hair, and two dryers are held in hand regardless of the size of hand or dexterity of the user.

A dryer joint has a base portion provided with two insertion portions, and air outlet grilles of dryers are inserted into the insertion portions to joint the two dryers. Thus air is blown in the same direction only paying attention to handles, and hair is dried more quickly than usual.
