It is intended to provide a posture-correcting exercise device (10) having a novel structure by which an effect comparable to traction can be easily established without resorting to use a large-scaled apparatus and which can be easily and conveniently operated and yet is expected as achieving effects of, for example, correcting spine distortion and reinforcing muscles supporting the spine to thereby fundamentally reduce the load on the spine when appropriately operated. To solve the above problem, the posture-correcting exercise device (10) has a chin rest portion, on which the chin of a user (34) is placed, at the upper end face and a setting face at the lower end face. The outer periphery of the setting face serves as a tilting face (26) in a curved shape. When the user (34) puts his/her chin on the chin rest portion, the device is tiltable at the setting face.
