BODY INCLINATION ANGLE MEASURING INSTRUMENT AND BODY TORSION ANGLE MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To provide a body inclination angle measuring instrument and a body torsion angle measuring instrument useful for the measurement of the rotation. SOLUTION: The tip ends 21a and 21b of a first arm 22 and a second arm 23 are abutted on specific sites of a body. Then, the first arm 22 and the second arm 23 are retained in an attitude as horizontally as possible. When the contacts of the first arm 22 and the second arm 23 are secured, a switch button 32 is pushed. A switch circuit specifies a measurement start position about a reference axis 17. The first arm 22 and the second arm 23 move from first measurement sites to second specific sites. The tip ends of the first arm 22 and the second arm 23 are abutted on the second specific sites. When the switch button 32 is pushed, the switch circuit specifies a measurement finish position about the reference axis 17. A rotation angle is measured between the measurement start position and the measurement finish position about the reference axis 17. This single body inclination angle measuring instrument 11 can thus attain the measurement of the inclination angle and the measurement of the rotation. COPYRIGHT: (C)2009,JPO&INPIT
