PROBLEM TO BE SOLVED: To provide a vibration detection type unlocking device capable of unlocking a key installed in a door by reliably operating upon detecting vibration regardless of how earthquake vibration is perceived.SOLUTION: A vibration detection type unlocking device includes: a substrate installed adjacent to a key of a door; a slide part in which an elastic member is housed so as to energize toward the key; an engaging pin provided in the slide part so as to project; a rotating body engageable with the engaging pin in a state in which the elastic member has accumulated energizing force; a first vibration detection part for detecting vibration in an almost horizontal direction of the substrate and moving in a pendulum manner; a first vibration transmission mechanism for converting a pendulum motion of the first vibration detection part into a linear motion and rotating the rotating body to release engagement with the engaging pin; a second vibration detection part that detects vibration in a direction substantially orthogonal to the substrate and moves up and down; and a second vibration transmission mechanism for converting the vertical motion of the second vibration detection part into a rotary motion and rotating the rotating body to release engagement with the engaging pin. |
