Claims

[Scope of utility model registration request]

The push rod of the master back to be assembled into the master cylinder of the brake device is adjusted so that the protrusion height of the push rod screwed onto the end of the rod is the specified assembly height dimension with respect to the depth of the piston recess of the master cylinder. This is a master back push rod adjusting device for adjusting the push rod, which includes a machine base having a back mounting part for positioning and fixing the master back in a state where the push rod is vertically oriented, and an elevating cylinder located above the back mounting part of this machine base. a fixed housing equipped with a movable body so as to be able to be raised and lowered by the push rod; A pusher is inserted into and engaged with the outer socket and a hollow rotary shaft rotatably supported within the housing so as to be rotatable around a vertical axis and rotationally driven by a stepping motor equipped with a movable body. A rotating pusher element having a socket hole for transmitting rotation and fitted between the rotary shaft and the outer socket and biased by a downward spring so as to transmit vertical movement and rotation to the rotary shaft. a lifting shaft fitted into the center hole of the rotary shaft so as to be movable up and down; a spring that biases the shaft so that the lower end of the shaft comes into contact with the inner end of the inner socket; A master back push rod adjustment device comprising a dial gauge for measuring the amount of movement at the upper end position of the shaft.
