Claims

[Scope of utility model registration request]

Hydraulic type for vehicles in which oil is filled in the upper and lower chambers of a cylinder whose interior is divided into two upper and lower chambers by a piston with an orifice, and the cylinder is attached to the wheel support member side and the piston rod is attached to the vehicle body side member. In a shock absorbing device, a bisto rod is provided with a communication passage that communicates the upper and lower chambers of the cylinder, and under certain temperature conditions, the communication passage maintains an open shape, and when the temperature conditions change, the passage deforms into a closed shape and returns to its original shape. The piston rod is equipped with a shape memory alloy that returns to its original shape with the communication passage open when the temperature is returned to the above temperature condition, and an electric circuit is provided to control energization of the shape memory alloy. Hydraulic shock absorber for vehicles.
