PROBLEM TO BE SOLVED: To obtain a door closure sensor device which copes with a clearance dimension in a wide range. SOLUTION: According to the structure of the door closure sensor, a box-shaped support member fixedly mounted on a door frame, is formed of a magnetic movable trigger and an elastic body for always energizing a projective portion of the movable trigger so as to project from an opening portion of a front cover. On the other hand a lock box fixedly mounted on an opening/closing body for opening/closing an opening of the door frame, is provided with a detecting means for detecting magnetic force of the projective portion of the movable trigger. Herein the movable trigger recedes to the inside of the support member according to a clearance dimension of the opening/closing body and against elastic force of the elastic body when the door is closed.
