A switch mounting structure of a door checker is provided to allow a controlling unit to sense the ground potential of a checker arm through a roller and a wire positioned in a contacting portion, thereby detecting as to whether a door is open or not. A switch mounting structure of a door checker comprises: a checker arm(112) coated with an insulation coating layer(112a); a checker carrier(120) equipped with a roller(10) and a roller housing(15); a contacting portion(30) to expose the ground potential of the checker arm to the outside in a closing state of a door; a wire(55) to deliver the ground potential of the contacting portion to a control unit(50). The checker carrier can be inserted into the checker arm to open the door step by step. The control unit is electrically connected to the roller housing. |
