<P>PROBLEM TO BE SOLVED: To provide a test indicator for allowing an assembling work to be easily performed without requiring a skill and also achieving high accuracy. <P>SOLUTION: A test indicator includes one of body cases 10A-10D; a movement unit 20 to be stored inside one of the body cases 10A-10D; and a dial unit 40. The movement unit 20 includes a gauge head 24 oscillatably supported by movement frames 21; a crown gear 26 rotatably supported by the movement frames; and an enlargement transmission mechanism for enlarging an oscillation amount of the gauge head and transmitting the oscillation amount to a rotation amount of the crown gear. The dial unit includes a needle 42 rotatably arranged in a dial frame 41; a scale plate 43 arranged along a turning region of the needle; and a pinion 44 for transmitting rotation of the crown gear to the needle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
