Claims

[Scope of Claim for Utility Model Registration] (1) A movable frame that is swingably mounted within the housing and partially exposed from one side of the housing, and a portion of the movable frame that is fixed at a fixed position within the movable frame and exposed from the housing. A heat ray sensor comprising: a heat ray sensor that detects heat rays entering the movable frame through a transparent part provided in the movable frame. (2) A pair of shaft pins protrudes from at least both radial ends on the side surface of the movable frame, and a pair of shaft pins are provided on the inner circumferential surface of the housing in a direction substantially perpendicular to the opening surface of the housing where the movable frame is exposed. The heat ray sensor according to claim 1, further comprising a guide groove into which the shaft pin fits. (3) A pair of elastic pieces protrudes from at least both radial ends on the side surface of the movable frame, and the elastic pieces run on the inner peripheral surface of the housing in a direction substantially perpendicular to the opening surface of the housing where the movable frame is exposed. A guide groove is formed in which the piece fits, and the elastic piece makes elastic contact with the bottom surface of the guide groove and has protrusions at the portions where it comes into elastic contact with the bottom surface of the guide groove, and engages with the protrusions at important points on the bottom surface of the guide groove. 2. A heat ray sensor according to claim 1, further comprising a recess formed therein. (4) A stepped portion is formed on the circumferential surface of the movable frame, and the rotating frame comes into contact with the stepped portion on the inner circumferential surface of the housing that rotates by a predetermined angle with respect to the housing, thereby preventing the rotating frame from moving. The heat ray sensor according to claim 2 or 3, further comprising a regulating stopper rib.
