の範囲第１項記載の光フアイバ型振動センサ。[Scope of Claim for Utility Model Registration] (1) A light transmitting optical fiber fixed to a sensor housing that transmits light from a light source, and a light transmitting optical fiber fixed to the sensor housing within the sensor housing so that its relative position with respect to the light transmitting optical fiber does not change. an elastic lens that is held and transparent in the used wavelength band and is formed of an elastic material and is deformed in response to vibration to change the optical path of the light emitted from the light transmitting optical fiber; a light-receiving optical fiber fixed to the sensor housing so that its relative position with respect to the light-transmitting optical fiber that receives the output light of the light-transmitting optical fiber that has passed through the body lens does not change; and the light-receiving optical fiber An optical fiber type vibration sensor characterized by being provided with a light-receiving element that photoelectrically converts light emitted from the fiber. (2) The optical fiber type vibration sensor according to claim 1, wherein the elastic lens is attached to the sensor housing via a spring to which a weight is attached, with the direction of expansion and contraction being in the vertical direction.
