The piston rod 2 having the oil passage 2a formed at the lower end thereof is integrally assembled to the end of the piston rod 2, and the oil in the rebound chamber 1a and the compression chamber 1b of the rod guide 1 is integrated. The piston 3 to allow the mutual entry and exit, and the space 4a is formed therein, and an oil hole 4b is formed at the bottom thereof to communicate with the oil passage 2a of the piston rod 2 so as to communicate with the rebound chamber 1a. And the sub-valve body 4 which is integrally assembled at the lower end portion so as to directly connect the compression chamber 1b and the space portion 4a in the sub-valve body 4, and is installed in the rebound chamber 1a and the compression chamber 1b. ) Works together A high information olt (5) having a supporting rod (5a) in the direction, a valve guide (6) integrally assembled by being fitted to the outer circumferential surface of the support rod (5a) of the high information olt (5), and an oil passage (7a) Sub-valve 7 which is assembled to move up and down under the guidance of the valve guide 6, and upper and lower discs 8 which are respectively installed on the upper and lower portions of the sub-valve 7 to open and close the oil passage 7a. ) And the upper and lower disc force members 10 and 11 to elastically support the upper and lower disks 8 and 9 to open the oil passage 7a in the low speed section and to shut off at a low speed or higher. It consists of low speed damping force frame of vehicle shock absorber.
