Zusammenfassung: | This application is based upon and claims the benefit of Japanese Patent Applications No. 2000-17820 filed on Jan. 21, 2000, the contents of which are incorporated herein by reference.
A pressure detecting apparatus is composed of a first case insert-molded with connector pins, and a second case made of metal. The first case and the second case are assembled together to form a pressure detection chamber hermetically sealed with an O-shaped ring sandwiched between seal surfaces of the two cases. The first case is formed by using a molding die that has a gate for injecting resin approximately in parallel with a seal correspondence surface for forming the seal surface of the first case. |
