A hanger device includes a suction cup, a faceplate, and a rotary operating member. The suction cup includes a disc portion, an externally threaded post, and a peripheral flange. The externally threaded post extends rearwardly from a rear side of the disc portion. The faceplate is disposed to rest against the rear side of the disc portion, and has an intermediate part formed with a through-hole for allowing the externally threaded post to pass therethrough. The rotary operating member is formed with an internally threaded hole, and engages threadedly the externally threaded post so as to enable the rotary operating member to urge the faceplate toward the suction cup, thereby securing the suction cup on a surface.
