Abstract
A wiper actuating mechanism for use in an oil pressure measuring gague is equipped with an additional auxiliary spring plate and a push rod guide sleeve in addition to an improved two-arm wiper and a round diaphram board which is provided with a vertical flange on the periphery thereof for confining a rubber packing in place. The two-arm wiper can assure constant contact of the wiper with two sides of a winding board on which a resistive wire is attached; and the push rod guide sleeve can retain a slidable push rod in place which is not welded to the diaphram board and to move linearly so as to precisely pivot the two-arm wiper; the auxiliary spring plate disposed right under the diaphram board is also intended to reinforce the operation of the diaphram.
