A damping force controlling valve assembly for a shock absorber is provided. The damping force controlling valve assembly includes: a main body part of a retainer having an inlet passage connected to a high pressure side of the shock absorber; a main valve generating a damping force while resisting a working fluid flowing in through the inlet passage; a spool rod part interacting with a spool inserted thereinto and supplying a working fluid through a connection port to a back-pressure chamber provided at the rear of the main valve; a solenoid part controlling a position of the spool to adjust a pressure of the back-pressure chamber; and an auxiliary valve disposed at an upstream of the main valve to generate a damping force in an extremely low speed section in advance of the main valve.
