Claims

[Scope of utility model registration request]

a sensor case having an external infrared incidence port; an infrared detection body disposed within the case and generating an electric charge according to the amount of change in the incident infrared radiation; a pair of opposing bodies having an infrared passing section and an infrared non-passing section; a vibrating body that vibrates to periodically displace the opening/closing degree of the infrared passing section of the pair of opposing bodies; An infrared sensor comprising: an infrared passing hole that limits an infrared incident field of view of the infrared detector to the entrance opening; and a shield body for shielding the infrared detector from noise.
