A dynamic damper is provided which includes a weight, an elastic member that supports the weight so as to allow vibration, and a damper case that houses the weight and the elastic member, wherein the dynamic damper also includes corner part checking means for checking at least some corner parts among corner parts where at least one end face of the weight and first and second side faces that are each continuous from the one end face and are adjacent to each other meet. This enables the ease of assembly to be enhanced by enabling a corner part of a weight to be checked when assembling the weight into a damper case, and also enables the state in which the elastic member is mounted on an end part of the weight to be easily checked.
