CHECK PLATE JOURNALLING STRUCTURE OF DOOR CHECKER

摘要

PROBLEM TO BE SOLVED: To prevent occurrence of rattling noises when opening/closing a door by eliminating rattling in a space between a pivot shaft of a bracket and a bearing hole of a check plate without too much increasing rotation torque of the check plate for the bracket in a door checker and to increase manual fixing property of the door checker for a door support body. SOLUTION: The pivot shaft 8 fixed on the bracket 7 is relatively rotatably pressed into the polygonal bearing hole 22 formed on the check plate 6. Many pressing parts and gaps 24 are alternately arranged between an inner peripheral surface of the bearing hole 22 and an outer peripheral surface of the pivot shaft 8 along the circumferential direction.
