PURPOSE:To assure reduction of dimensions and improve measuring accuracy, by interaction of rock fixed to a main body and driving pinion supported by a free-moving slider and rotation of a pointer of a dial indicator caused by the interaction. CONSTITUTION:Driving pinion 19 and pointer pinion 20 are fixed on a supporting member 22 unavailable for relative change of position and slider 3, rack 8 and energizing means are installed. And, when the slider 3 is displaced along the master scale 2, a pinion 19 is rotated by the rack 8, this rotation is transmitted to a pinion 20 through intermiate geavs 25, 26 allowing reading of a measured value by indication of a pointer 16. And, as on this occasion, the whole gear mechanism is swuung and energized by an energizing means 30 pressing the pinion 19 firmly against the rack 8, supporting strength of the pinion 19 becomes available. Further, as oblique engagement a of pinion 19 and rack 8 are avaided overall correct engagements are available, measuring accuvacy can be improved. |
