PROBLEM TO BE SOLVED: To easily obtain followability with respect to a seal groove part by suppressing enlargement of an electronic control device by making a liquid-state sealant applicable in an axial seal structure.SOLUTION: Within a housing 10 including a first housing member 3 and a second housing part 2 which can be joined to each other and joining the housing members by inserting a junction 32 of the first housing member 3 into a junction 26 of the second housing member 2, a circuit board 4 is accommodated. On a composition plane of any one of the junctions 26 and 32, a seal groove part 33 for axial sealing that extends along the composition plane is formed. In the junction 26 of the second housing member 2, a communication hole is formed. The communication hole penetrates between an outer peripheral side of the junction 26 and the composition plane 26a and is being communicated to the seal groove part 33 in a housing junction state. The seal groove part 33 is filled by injecting the liquid-state sealant through the communication hole in the housing junction state.SELECTED DRAWING: Figure 1 |
