PROBLEM TO BE SOLVED: To facilitate installation of a base housing in a heat sink when configuring an air volume control module. SOLUTION: Claw parts 46, 48, 50 and 52 for damming up the heat sink 32 are projectingly formed in the vicinity of an insertion opening 6 of the base housing 34. While, locking projections 38, 40, 42 and 44 are formed in a position corresponding to a position of the claw parts 46, 48, 50 and 52 in the heat sink 32, and a return part 54 of the claw parts 46, 48, 50 and 52 dams up these locking projections 38, 40, 42 and 44. Thus, the base housing 34 is installed in the heat sink 32. Further, the heat sink 32 is formed with protective projections 56, 58, 60 and 62 arranged in the vicinity of the claw parts 46, 48, 50 and 52 and larger in a dimension in the height direction than the claw parts 46, 48, 50 and 52. Breaking of the claw parts 46, 48, 50 and 52 is prevented by these protective projections 56, 58, 60 and 62. COPYRIGHT: (C)2010,JPO&INPIT
