とするドアチェッカー。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 and 7, and the piston 5 is urged to slide toward the second chamber 7 by a spring 10. At the same time, the pinion gear 1 hits the main body 1 with the door A8 and rotates six times.
5 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 A is closed, the piston 5 slides toward the second chamber 7 side. , the piston 5 has a first chamber, a second chamber 6, and a second chamber 6.
A communication hole 11 is bored through which the main body 1 communicates with the main body 1.
A member is provided that closes the communication hole 11 when the piston 5 slides a predetermined stroke toward the first chamber 6, and furthermore, the first and second chambers 6 and 7 are connected to which chamber 6.
・When the hydraulic pressure in 7 exceeds the set force, the first
and a second check valve 30°40.
