とするドアチェッカー。[Claims for Utility Model Registration] A piston 5 with rack teeth 13 is fitted into the cylinder hole 2 of the main body 1 to form first and second chambers 6. A rotating pinion gear 1 is connected to the main body 1 and the door A and is slidably biased toward the chamber 7 side.
6 is provided in mesh with the rack teeth 13, so that when the door A is opened, the piston 5 slides toward the first chamber 6 side, and when the door opens, the piston 5 slides toward the second chamber 7 side. In the checker, a brake shoe 20 loosely fitted onto the support shaft 17 of the pinion gear 16 is fixed to the main body 1, and the cam surface 14 facing the brake shoe 20 is fixed to the piston 5.
The cam surface 14 and the brake shoe 20 are connected to the piston 5. The door checker is characterized in that the brake shoe 20 brakes the support shaft 17 when the door slides toward the first chamber 6 by a predetermined stroke L1.
