<p>PURPOSE:To improve the electric wave interference resistance characteristics and thermal shock durability of an electrical heating resistance type air flow rate measuring device adopting resin body. CONSTITUTION:An electromagnetic shield pipe 15 consisting of alumina or brass is inserted (one-piece molding) into a resin body 11 and external electric wave arriving at an intake air flow rate detection part, etc., is mode to escape to the ground, thus drastically improving the electric wave resistance characteristics and thermal shock durability of an electical heating resistance type air flow rate measuring device adopting the resin body 11 by a simple method.</p> |
