The cans 50 in six rows on each rail member 56 of the carrying section are carried in the direction of arrow U by a not-shown pushing and carrying mechanism. Here, when each can 50 passes below the corresponding distance sensor 51, each distance sensor 51 detects the distance between each distance sensor 51 and the can lid 50a of the can 50. If the detected value is smaller than the preset allowable range, the can lid 5 is caused by the high internal pressure of the can 50.
The bulge of 0a is judged and this can is regarded as a defective product. On the other hand, when the internal pressure of the can is smaller than the specified value, the can lid 50a
Is dented, and the value detected by the distance sensor 51 becomes larger than a preset allowable range. The cans 50 are continuously conveyed in the conveying direction U.

When changing the can type, for example, a 5 ml can 5
When transporting 0, one rod 61 of the cylinder 60
a is extended and the other rod 61b is retracted, so that each drive pin 75 is moved to the driven plates 68, 69.
The sensor support plate 67 provided with each distance sensor 51 may be located in the ascending position by locating the sensor support plate 67 in each of the positioning groove portions 68c below. As described above, according to the height type of the can 50, the space adjusting means having the cam member allows the can lid 50a.
The setting position of the distance sensor 51 with respect to can be easily changed. That is, depending on the height type of the can 50, the distance sensor 5
It is possible to provide a simple and inexpensive can internal pressure inspection device that can adjust the position of No. 1 and efficiently inspect the internal pressure of the can 50 filled with contents.
