Title:
Caulking structure
Document Type and Number:
Japanese Patent JP6231463
Kind Code:
B2
Abstract:
The present invention provides a swaging structure having a high pressure resistance strength suitable for a high pressure switch that solves the conventional disadvantages that the swaging for providing an increased thickness causes a manufacturing facility having a larger size or the swaged part having winkles or that a pressure switch finds a difficulty in the adjustment of the swaging margin when the number of diaphragms is changed for example. A swaging structure comprises at least a to-be-swaged member required to have airtightness to a surrounding environment and a swaging member configured to retain the to-be-swaged member by a swaging processing, the swaging member has an annular side wall surrounding the to-be-swaged member to retain the to-be-swaged member after the swaging processing and the swaging structure further includes an annular spacer including therein a penetration hole to be sandwiched between the to-be-swaged member and the annular side wall after the swaging processing.
