Claim:
A scroll fluid machine comprising: a housing including refrigerant for an air-conditioner; a scroll unit contained in said housing and having a fixed scroll and a movable scroll; an armature contained in said housing adjacently to the movable scroll of said scroll unit and configured to revolve the movable scroll to compress the refrigerant, said armature including a plurality of stator coils; and a connection device for electrically connecting each of the plurality of stator coils of said armature to a feeder circuit external to said housing, said connection device including: a housing wall forming part of said housing and having a through hole, a tubular lead holder extending from inside said housing through the through hole to outside of said housing, the tubular lead holder having a center hole extending through the tubular lead holder in an axial direction thereof, a head located inside said housing, an outer end portion located outside of said housing, and snap anchors protruding integrally from the outer end portion in a radially outward direction of the tubular lead holder and engaging with an outer surface of the housing wall, the snap anchors being elastically deformable in the radially outward direction of the tubular lead holder, and having a distal end directed toward the housing wall, and a gap between each of the snap anchors and an outer peripheral surface of the tubular lead holder such that the each of the snap anchors can elastically deform about a base thereof in directions toward and away from the outer peripheral surface of the tubular lead holder, the tubular lead holder including the head, the outer end portion, and the snap anchors being a one-piece member of molded synthetic resin that is impermeable to the refrigerant, a lead electrically connected to a stator coil of the plurality of stator coils, the lead extending from the stator coil to outside of said housing through the center hole of the tubular lead holder and connected to the feeder circuit, and a seal structure configured to keep the tubular lead holder gastightly sealed with respect to the housing wall and further configured to keep the lead gastightly sealed with respect to the tubular lead holder, the seal structure preventing leakage of the refrigerant, the seal structure including a first seal member configured to gastightly seal a space between an inner peripheral surface of the through hole in the housing wall and the outer peripheral surface of the tubular lead holder and a second seal member configured to gastightly seal a space between an inner peripheral surface of the center hole and the outer peripheral surface of the lead, the first and second seal members being separate from the tubular lead holder, wherein, when the tubular lead holder is fitted to the housing, the each of the snap anchors cooperate with the head to hold the housing wall between each distal end of the each of the snap anchors and the head.
