Device for attaching motor protector and encapsulated-type electric compressor

An attachment device for attaching a heat response-type motor protector for protecting a motor incorporated in an encapsulated-type electric compressor to a compressor container of the encapsulated-type electric compressor, the attachment device comprising:

• an accommodating member that is configured of a material with an electrical insulating property and is able to accommodate the motor protector in a state where a part of a periphery of the motor protector is opened;
• and
• a fixation member that is fixed to an inner surface of the compressor container and is able to fix the accommodating member to the inner surface of the compressor container with the accommodating member accommodating the motor protector detachably attached to the fixation member, wherein
• the fixation member includes
• a base portion that is formed into a plate shape facing the inner surface of the compressor container, and
• at least two arm portions that are provided at positions where the arm portions sandwich the accommodating member on both outer sides, and extend from the base portion to a side of the accommodating member,
• the two arm portions are configured such that once the accommodating member is pushed to inside of the two arm portions, at least one of the two arm portions is elastically opened in a direction away from the other to receive the accommodating member, and once the accommodating member is pushed to a predetermined position, the two arm portions are able to sandwich and hold the accommodating member between the two arm portions with a restoring force of the elastically opened arm portion, and
• the fixation member further includes assisting portions that extend from the base portion to the side of the accommodating member, are caused to pass through assisting portion insertion holes provided in the accommodating member and stick out inside the accommodating member and at positions where the assisting portions sandwich the accommodating member with the arm portions in a case where the accommodating member is attached to the fixation member, and cause an elastic force to act on the accommodating member to restrict movement of the accommodating member in a case where the accommodating member moves in a direction that is parallel to the base portion.
