This protective cover body 90 is formed into the shape of a box by injection molding a synthetic resin, and comprises a box covering portion 94 for covering a box cover body 70 and a connector covering portion 96 for covering the installation zones of the connectors 59 of the control substrate 60. Further, a seal covering portion 95 for covering a sealing means 80 is formed at one side of a peripheral wall 92 of the protective cover body 90. The protective cover body 90 is opened and closed by rotating around a hook-shaped hinge portion 93 formed on one outside surface of the peripheral wall 92, and locked by a locking means 100 on the outside of the storing box 61 when the protective cover body 90 is closed.
