Claims

[Scope of Claim for Utility Model Registration] (1) A sensor block that includes a pyroelectric element that detects heat rays emitted from the human body and a lens provided in front of the detection surface of the pyroelectric element; The sensor block is formed by a spherical sensor body in which a pyroelectric element is housed, and a holder that rotatably holds the sensor body. A presser metal fitting that holds the sensor block between the cover and the cover is fixed, and the presser metal fitting has an opening in the center.
At least a part of the outer circumferential surface of the sensor block is spherical and has a plurality of dimension adjustment ribs projecting thereon, and is attached in such a manner that the dimension adjustment ribs are in pressure contact with the periphery of the opening of the presser metal fitting. Heat-sensitive automatic switch. (2) The cover is formed with a support protrusion that supports the circuit board connected to the pyroelectric element, and a pair of hooks that are hooked on both sides of the circuit board, and the presser metal fitting is formed with a support protrusion that supports the circuit board connected to the pyroelectric element, and a pair of hooks that are attached to the outer surface of each hook. 2. The heat-sensitive automatic switch according to claim 1, further comprising a presser protrusion that prevents the distance of the hook from increasing.
