Abstract

PURPOSE: To realize the gas enclosure into a container without using any welding machine and thus realize a protection of the vibration detection part, by storing the vibration detection part into the container in the sealed gas and then enclosing the sealed gas into the container.
CONSTITUTION: The vibration detection parts 21W23 plus 25 which generate the analog vibration output according to the intensity of the knocking vibration of an internal combustion engine are stored into the container formed with the housing 27 and the sealing plate 28. Then the housing 27 and the sealing plate 28 are fixed together via the calking 27b in the sealed gas after storing the vibration detection parts into the container in the sealed gas, and then the sealed gas is enclosed into the container. Accordingly, the sealed gas can be enclosed into the container without using any welding machine, thus protecting the vibration detection parts from stain, humidity and the like.
