PROBLEM TO BE SOLVED: To provide an EGR device which can perform an airtight test of a valve driving chamber without drilling a through-hole on a housing body, a connector housing or the like.SOLUTION: On a sensor cover 5 of an EGR device, two motor terminals and three sensor terminals are insert-molded and, on a surface of at least one terminal (test terminal T) among the terminals, a pressure-introducing groove 25 for introducing a pressure to a valve driving chamber when an airtight test is performed is formed. The pressure-introducing groove 25 is formed such that one edge side is extended to a male terminal 20a protruding from a bottom surface 24a of a connector housing 24 and the other edge side is extended to the inner circumferential side of the sensor cover 5 from a seal groove 19. Meanwhile, on the sensor cover 5, a window hole 26 reaching the surface of the test terminal T is formed on the inner circumferential side from the seal groove 19 and the other edge side of the pressure-introducing groove 25 is exposed toward a gear chamber 15 through the window hole 26. |
