A seal structure includes a connector-lower-surface-side flat seal portion constituted by a surface-joint portion between a lower surface of a connector and a lower housing member; and a groove seal portion constituted between a groove and a protrusion fitted into the groove. The groove is provided in one of inner surfaces of outer circumferential edge portions of an upper housing member and the lower housing member. The protrusion is provided in another of these inner surfaces. The seal structure further includes a linking seal portion connecting the connector-lower-surface-side flat seal portion with the groove seal portion. The linking seal portion includes a deep-bottom portion having a seal groove continuous with the groove seal portion, a shallow-bottom portion having a seal groove shallower than the seal groove of the deep-bottom portion and continuous with the connector-lower-surface-side flat seal portion, and a connecting portion linking the deep-bottom portion to the shallow-bottom portion. |
