PROBLEM TO BE SOLVED: To provide a rotary meter head structure for largely improving convenience. SOLUTION: This rotary meter head structure mainly includes a meter head, a meter base, a rotary part and a joining part. The meter head is arranged above the meter base, and has an outer thread under its head, and has a sensing part inside the meter head. The meter base is arranged under the meter head, and is fitted to the outside of the rotary part, and moreover, is arranged by being sandwiched between the meter head and the rotary part, and has an inner thread on its inside. The rotary part is an annular structure, and is threadedly combined with the meter head, and some recessed tubs are arranged on its head, and closely copes with an oil seal. An outer thread is provided above the joining part, and threadedly engages with the meter base, and its lower part is combined with a machine facility. In this invention, the meter head can optionally rotate by 360 degrees by the extension of the rotary part, and the meter head is released from restriction of a display angle.
