摘要： To assemble liquid level indicator having an indicator frame, a contact holder, a resistor, a contact and a float in an automatic assembly system, the contact holder is formed into a crank shape having a first arm for holding the contact and a second arm for holding the float arm. Therefore, the contact holder can be assembled with the frame when moved in the direction the same as that along which the other parts are moved for assembly with the frame. Further, the contact is assembled when moved in the same direction, and the contact holder is temporarily fixed to the indicator frame for further facilitating the assembly work of the liquid level indicator.

摘要： A motor-driven disk brake is capable of functioning as a parking brake satisfactorily without degrading the brake operating feeling and impairing the function of operating as a motor-driven brake. A stator and rotor of an electric motor are provided in a caliper body floatably supported on a carrier. The rotation of the rotor is transmitted to a piston after being converted into rectilinear motion through a ball-and-ramp mechanism and an adjusting nut. The piston, together with a claw member, presses brake pads against a disk rotor. A rotation assisting device is provided between the rear end of the rotor and a motor casing. A rotary disk constituting the rotation assisting device is rotated through a wire extending from an external operating member.

摘要： An electrically actuated booster capable of obtaining various desired brake characteristics and improving brake feeling performs displacement control such that the relative displacement relationship between an input member and an assist member is variable according to the absolute displacement of the input member.A target displacement that makes variable the relative displacement relationship between an input piston and a booster piston is set according to a detection signal from a potentiometer (86) (input absolute displacement detecting means), and displacement control is performed so that the relative displacement between the two pistons becomes equal to the target displacement on the basis of a signal from a relative displacement sensor (100) that detects the relative displacement between the two pistons.

摘要： An electrically actuated brake booster capable of obtaining a desired boost ratio for a given input pressure when an electric actuator is activated as a boost source, so as to ensure a desired operability of a brake pedal. The electrically actuated brake booster comprises: an input piston 22 to which an input thrust is applied through an input rod 9 that moves in coordination with operation of a brake pedal 8; and a booster piston 21 to which a booster thrust is applied by an electric actuator 40 that uses an electric motor 41 as a drive source, such that the input piston 22 and the booster piston 21 are disposed to be movable relative to each other but are normally maintained in a neutral position of relative displacement by means of springs 34. While an amount of relative displacement between the pistons 21 and 22 is determined by the potentiometer 45, the electric motor 41 is controlled to adjust the amount of relative displacement to a predetermined value. At the same time, a reaction force acting on the input piston 22 resulting from a hydraulic brake pressure is offset by urging forces of the springs 34 to thereby obtain a desired level of boost ratio.

摘要： A motor-driven disk brake has a first brake pad and a second brake pad disposed at opposite sides of a disk rotor, a piston disposed so as to face the first brake pad, a claw portion extending over the disk rotor and facing the second brake pad, and an electric motor disposed in the vicinity of the piston. A ball ramp mechanism for converting rotation of the electric motor to a linear motion is disposed between the first brake pad and the electric motor. When the motor is operated, the piston is reciprocally moved by the ball ramp mechanism, to thereby enable application and removal of a braking force relative to the disk rotor by the brake pads.
