ROTATIONAL ANGLE DETECTOR, COMBINING STRUCTURE AND JOINT MEMBER BETWEEN RELATIVE ROTATION MEMBERS

摘要

PROBLEM TO BE SOLVED: To facilitate and quicken positioning of a rotational member. SOLUTION: A rotational angle detector 1 comprises a detection part 10 and rotor 20 mutually freely rotatable via contact surfaces and a potentiometer 12 detecting relative rotation angle between the detection part 10 and the rotor 20. The detection part 10 has a cylindrical outer shape support 14 whose outer surface is a contact support surface 14c, and the rotor 20 has a pair of pinching members 50 and 60 provided with semicircle recess parts 51 and 61 being an inner surface forming a part of a circle and stop screws 71 and 72 capable of individually tightening both sides of the semicircle recess parts 51 and 61. The inner surface of the pinching members 50 and 60 forms a contact surface contacting the support surface of the support part 14. COPYRIGHT: (C)2003,JPO
