Claims

[Scope of utility model registration request]

A pressure detection section is provided in the housing, and a high pressure chamber and a temporary pressure chamber are provided on both sides of this pressure detection section, and the high pressure chamber and low pressure chamber are each communicated with the pressure detection section through a communication passage, and the high pressure chamber and A fluid circuit is provided in which a fluid is sealed across the low pressure chamber and the pressure detection section, and this fluid flows between the high pressure chamber and the low pressure chamber in response to external pressure changes applied to the pressure receiving section of the high pressure chamber. A pressure detector characterized in that an elastic member is provided between the part and the housing to counteract external pressure.
