Abstract
An air flow rate measuring device includes a housing, a sensor assembly, and an urging mechanism. The housing defines an internal flow passage, through which air taken in by the device passes, and the housing includes a contact surface. The sensor assembly includes a sensor chip and a contact surface. The sensor chip is configured to generate an electrical signal through a heat transfer phenomenon. The sensor assembly is inserted and fixed in the housing such that the sensor chip is exposed to the internal flow passage. The contact surface of the sensor assembly is in surface contact with the contact surface of the housing. The urging mechanism is configured to press the contact surface of the sensor assembly on the contact surface of the housing, so that the sensor assembly is fixed to the housing by the urging mechanism.
