Abstract

A housing assembly for a fan unit includes an upper housing having a lower engaging portion adjacent to its lower end surface and a lower housing having an upper engaging portion adjacent to its upper end surface. When one of the upper and lower housings rotates relative to the other about a center axis of the housings in a first direction with the opposing end surfaces of the housings in axial contact, the lower and upper engaging portions engage with each other. While the lower and upper engaging portions are in engagement, one of the lower and upper engaging portions presses the other in both axial directions to cause elastic axial deformation of the other; and one of the lower and upper engaging portions presses the other toward both the first direction and a second direction opposite thereto to cause elastic circumferential deformation of the other.
