PROBLEM TO BE SOLVED: To provide a door checker device operable by two-stage opening operation capable of performing the opening operation in a state of being fully opened after a half opening state has been held so that a door can not be suddenly opened until it is in a fully opened state. SOLUTION: A check plate 4 is formed with a guide groove 4c along the sliding direction and opening to a position on this side of a full opening stopper 8, a retractable stopper pin 9 provided to a sliding resistance display means 7 moved in the direction at an approximately right angle relative to the guide groove 4c, at the same time, moving along the guide groove 4c in a state of entering and a disengagement means 10 so as to open the door 3 to a fully opened position abutting on the full opening stopper 8 on the sliding resistance display means 7 when the retractable stopper pin 9 is backed from the guide groove 4c to be released, although the door 3 is constrained to open wider than an intermediate opening position on this side of a fully opened opening when the retractable stopper pin 9 enters the guide groove 4c to be engaged with a terminal 4d of the guide groove 4c.
