Title:
Air mass flow detecting device
Document Type and Number:
Japanese Patent JP6181900
Kind Code:
B2
Abstract:
The objective of the present invention is to provide an air flow rate detecting device with which the inflow of air to the reverse surface of a diaphragm is reduced, while stresses acting on a flow rate detecting unit are alleviated and variability in the mounting of the flow rate detecting unit is reduced. This air flow rate measuring device comprises : a flow rate detecting unit 602 including a diaphragm which detects the air flow rate of a gas being measured; a circuit board 400 on which the flow rate detecting unit is mounted; and a housing which accommodates the circuit board. The flow rate detecting unit and the circuit board are secured to one another using a sheet-like adhesive 803, and are secured in such a way that a surface of the flow rate detecting unit that is perpendicular to the direction of flow is sealed by means of a resilient body, and a surface of the flow rate detecting unit that is parallel to the direction of flow is open.
