Claims

[Claims for Utility Model Registration] (1) An outer braking member that contacts the cylinder, an inner braking member that contacts the piston, a body, a spring installed in the body, and a biasing force of the spring. The outer brake includes a plunger whose tip portion is in constant contact with a member integral with the inner brake member, and a switch that is turned on when the plunger protrudes beyond a certain distance due to wear of both brake members. A wear warning sensor fixed to a member that moves together with the brake member, a display means for notifying wear of the braking member, and a wear detection circuit that lights the display means when the switch is turned on. Pad wear warning device. (2) The wear warning sensor further includes: a notch in the body; a rod-shaped lever that is integrated with the plunger in the notch; and by locking the lever in the notch, the plunger is prevented from wearing out. Claim (1) characterized in that the warning sensor can be held while being inserted into the warning sensor.
) Pad wear warning device.
