An end of a lever (6) that can swing about a fulcrum shaft (5) fixed to the main body (1) contacts the other end of the pin (3). A pin (9) fixed to the end of the lever (8) loosely engages the groove (7) provided at the other end of L/ /<-(a). The lever (8) is fixed to the outer periphery of the hollow shaft (11) that is loosely engaged with the fulcrum shaft α0) that is fixed to the main body (1),
The seat plate (12) and the lever (13) are loosely matched. By interposing a compression coil spring (I5) between the lever (13) and the retaining ring 0→, the lever (8), seat plate (12), and lever 03) are pressed together. The seat plate (12) is made of rubber or synthetic resin, and the lever (8) and lever 03)
In order to increase or stabilize the frictional contact resistance against
There is a lot. Both ends of the tension coil spring (16) are attached to the main body (
1) side and the lever (6) side, respectively. A scale plate 08) is fixed to the main body (1) in order to read the movement of the pointer (17) fixed to the lever (13). Main body (
The end of the push rod @0) fitted in the hole (19) of 1) is fixed to the hook e0, and there is a compression coil spring @0 between the main body (1) and the push rod.

腐蝕部(ハ)の深さを判定できる。Also, the movement and position of the lever (6) at this point has no purpose. Next, using the reaction force of ) on the compression coil spring,
When the push lever (20) and the hook 0υ are returned to the cut-off position (the end of the 7-knob 0υ touches the inside of the main body (1)), the inside (21b) of the hook 01) will move the lever (13) toward the arrow (S).
) direction. At this time, the lever (6) is interlocked via the lever (8), pin (9), and fulcrum shaft (5).
The end of the pin (3) presses against the end plate (4)
Projection dimension = Y). Then, the arc movement of the lever (8) stops, but due to the sliding phenomenon of the seat plate (12), the lever (8) stops moving in an arc.
13) continues to move in an arc until the hook eυ stops (the end surface of the hook eI hits the inside of the main body (1)). At this time, the scale position of the pointer α7) is the O scale (reference point). Next, if the main body (1) is moved so that the end of the pin (3) fits into the corroded part (c), the pin (3) will move into the corroded part (c) due to the effect of the tension coil spring (16). Depth dimension (X
). At this time, since the pointer αη also moves in the direction of the arrow (T), the depth of the corroded portion (c) can be determined by reading the amount with the scale plate (18).

The mutual spacing between 3) and 3 supporting legs) is arbitrary. Furthermore, as the embodiment M of Fig. 1, the supporting legs (C) may be arranged as shown in Fig. 5. Effects of the Invention According to the present invention, the radius of curvature of the LP gas container end plate changes (output). Even if the substitute dimension (Y) changes), the pointer can be easily readjusted to the 0 scale (reference point), so it can be used with many types of LP gas containers. It can also be used to approximate the depth of corrosion on curved surfaces other than LP gas containers.
