Claims

[Scope of utility model registration request]

(1) In a pressure gauge for a spot welding machine, which is constructed by connecting a hydraulic cylinder equipped with a pressure piston and a Bourdon tube meter for oil pressure measurement via an oil passage, the zero point position of the pointer of the Bourdon tube meter or its A pressure gauge for a spot welding machine characterized by a stopper having a shock absorbing function arranged near the pointer and at a position where it can come into contact with the pointer.

(2) The pressure gauge for a spot welding machine according to claim 1, wherein the stopper is made of a plate spring material.

(3) The pressure gauge for a spot welding machine according to claim 1, wherein the stopper is constituted by a coil spring material.

(4) The pressure gauge for a spot welding machine according to claim 1, wherein the stopper is constituted by a frame body stretched with a rubber material.

(5) The pressure gauge for a spot welding machine according to item 1 of the utility model registration claim, wherein the stopper is constituted by a frame on which a spot material is stretched.
