    摘要： In a blind device, comprising a fixed frame 1, at least a pair of arms 5 each having an end pivotally attached to the fixed frame, a moveable frame 4 which is adapted to move toward and away from the fixed frame in a parallel relationship by rotational movements of the two arms, and a light-shielding screen 3 having one end fixedly attached to and wound around a roll 2 which is pivotally supported by the fixed frame, and another end fixedly attached to the moveable frame, characterized by that; a pivot shaft for pivotally supporting each arm on the fixed frame is incorporated with spring means 16 which resiliently urges the corresponding arm toward its upright position, and the blind device further comprises an electric actuator 17 having reverse drive preventing means for applying a rotative force to the roll so as to wind the screen thereon against a spring force of the spring means. Thus, the resilient force of the spring means applies a moment to the arms to urge it toward their upright positions, and the torque of the electric actuator winds the screen onto the roll. Because the electric actuator would not be reverse driven, once the electric actuator is stopped, the screen is kept stationary with a desired length thereof pulled out. Furthermore, because the resilient force of the spring means is always applied to the arms, the screen would not slack at any extended position. Also, by controlling the rotational speed of the electric motor, the speed of paying out and winding the screen can be controlled in a stable fashion.

    摘要： A compression coil spring is used as a return spring which is stored in the housing of a clutch to urge the clutch piston in its returning direction. The effective number of turns of the compression coil spring is two or less, and the number of turns at an end-turn portion thereof is more than 0.45 and not more than 0.7. The compression coil spring is used in the compressed state throughout the operating stroke of the clutch piston. The number of turns at the end-turn portion is desirably within the range of 0.5 to 0.65, more desirably within the range of 0.55 to 0.62.
