An electrical shock absorber comprising: a motor which is rotated by approaching and separating motions between first and second members which approach and separate from each other; and an electric circuit which connects two electric terminals (t1, t2) provided on the motor so as to cause current to flow through the motor, the electrical shock absorber being configured such that, when the motor is rotated by an approaching motion or separating motion between the first and second members, an induced voltage appears between the two electric terminals (t1, t2), and an induced current flows through the motor and the electric circuit, whereby the electrical shock absorber generates a damping force against the approaching motion or separating motion between the first and second members, wherein a field effect transistor (56, 60) is provided in the electric circuit; the field effect transistor (56, 60) is connected to the electric circuit such that the induced current flowing through the electric circuit can flow through a drain-source path of the field effect transistor; and the field effect transistor (56, 60) limits the magnitude of the induced current flowing through the electric circuit on the basis of a characteristic of the field effect transistor (56, 60) in terms of change of a drain-source current iDS with a gate voltage VGS which is applied to the field effect transistor (56, 60) and is changed on the basis of relative speed between the first member and the second member, characterized in that the field effect transistor (56, 60) is a P-channel junction field effect transistor; and the magnitude of the drain-source current iDS decreases as the gate voltage VGS of the field effect transistor (56, 60) increases. a motor which is rotated by approaching and separating motions between first and second members which approach and separate from each other; and an electric circuit which connects two electric terminals (t1, t2) provided on the motor so as to cause current to flow through the motor, the electrical shock absorber being configured such that, when the motor is rotated by an approaching motion or separating motion between the first and second members, an induced voltage appears between the two electric terminals (t1, t2), and an induced current flows through the motor and the electric circuit, whereby the electrical shock absorber generates a damping force against the approaching motion or separating motion between the first and second members, wherein a field effect transistor (56, 60) is provided in the electric circuit; the field effect transistor (56, 60) is connected to the electric circuit such that the induced current flowing through the electric circuit can flow through a drain-source path of the field effect transistor; and the field effect transistor (56, 60) limits the magnitude of the induced current flowing through the electric circuit on the basis of a characteristic of the field effect transistor (56, 60) in terms of change of a drain-source current iDS with a gate voltage VGS which is applied to the field effect transistor (56, 60) and is changed on the basis of relative speed between the first member and the second member, characterized in that the field effect transistor (56, 60) is a P-channel junction field effect transistor; and the magnitude of the drain-source current iDS decreases as the gate voltage VGS of the field effect transistor (56, 60) increases.
