PROBLEM TO BE SOLVED: To provide a makeup plug applicable to structures with various plate thicknesses and manufacturable at low cost. SOLUTION: A pair of plug bodies 2 are connected to each other through a long adjusting shaft 3 to form the makeup plug 1. When one plug body 1 is press-fitted into a refill hole after the other plug body 2 is press-fitted into the refill hole, only the first press-fitted plug body 2 is brought into contact with the inner surface of the refill hole until the other plug body 2 connected to the length adjusting shaft 3 of the makeup plug 1 reaches the refill hole to reduce a friction force acting between the makeup plug 1 and the refill hole so that the makeup plug 1 can be easily press-fitted. When the diameter of the refill hole is constant by the change of the diameter according to the plate thickness of a member having the hole refilling the length of the length adjusting shaft 3, the pair of plug bodies 2 can be commonly used even if the plate thickness of the member is changed.
