Abstract: A robot device of the present disclosure includes at least one artificial muscle that operates by being supplied with liquid; and a liquid supply device that supplies and discharges the liquid to/from the artificial muscle, and the liquid supply device includes a liquid storage part that stores the liquid; a pump that sucks the liquid from the liquid storage part and discharges the liquid; a pressure regulating device that includes a spool and an electromagnetic part that allows the spool to move, and that generates drive pressure for the artificial muscle by regulating source pressure from the pump side, and regulates the source pressure by balancing at least a force given to the spool from the electromagnetic part and a force given to the spool by action of the drive pressure; and a control device that applies a current to the electromagnetic part of the pressure regulating device so that the drive pressure reaches target pressure.

Abstract: A robot device of the present disclosure includes at least one artificial muscle that operates by being supplied with liquid; and a liquid supply device that supplies and discharges the liquid to/from the artificial muscle, and the liquid supply device includes: a liquid storage part that stores the liquid; a pressure regulating valve that regulates pressure of the liquid from the liquid storage part and supplies the liquid to the artificial muscle; and a liquid keeping part that allows the artificial muscle to keep the liquid supplied to the artificial muscle, according to occurrence of an abnormality, and the liquid supply device can allow the artificial muscle that operates by being supplied with liquid to operate properly.

Abstract: A lock shaft and a shaft member (a plunger and a permanent magnet) of a magnetic locking device are arranged such that a moving direction thereof is orthogonal to a moving direction of a piston rod of a hydraulic actuator. In a parking lock released state, when the coil is not energized, the lock shaft and the shaft member are locked by an attracting force between the permanent magnet and a flange of a yoke so as not to move back from the piston rod, and, when the coil is energized, the attracting force between the permanent magnet and the flange is canceled, so that the lock shaft and the shaft member are allowed to move back from the piston rod.

Abstract: A detent lever 20 and a piston rod 42 are engaged with each other through engagement between a recessed portion 26 of the detent lever 20 and a pin portion 52 of a retainer member 50 attached to the piston rod 42. With this configuration, the detent lever 20 and the piston rod 42 can be engaged with each other easily and in a short time when assembling a parking device 10. As a result, the time required for the work of assembling the parking device 10 can be shortened.

Abstract: When an oil temperature Toil is equal to or lower than a threshold Toref, and when a vehicle is predicted to stop while traveling (a shift position is predicted to be operated to a parking position), restricted discharge processing is executed in which a magnetic lock device is turned ON and an on-off solenoid valve is turned OFF. Thus, discharge of hydraulic oil in an oil chamber is started while movement of a piston rod is restricted by the magnetic lock device. Then, when the vehicle stops and the shift position is changed to a parking position, the restriction on the movement of the piston rod is removed by turning OFF the magnetic lock device.

Abstract: An object of the present invention is to provide a method for manufacturing a connector terminal received in a terminal-receiving chamber, passing through a sealing member, and brought into close contact with the sealing member, and a connector, which are the method for manufacturing a connector terminal, and the connector, for improvement in close contact between the sealing member and the connector terminal. Provided is a method for manufacturing a connector terminal received in a terminal-receiving chamber of a housing, passing through a sealing member filled in the terminal-receiving chamber, and brought into close contact with the sealing member, and the method includes a first process of punching a non-plated metal plate to form an intermediate material and a second process of covering the intermediate material with plating.

Abstract: A connector unit has a male connector that includes a cylindrical proximal portion in which a female terminal is accommodated, and a female connector that includes a tubular proximal portion in which a male terminal is held. The cylindrical proximal portion has a cylinder side marking portion including a flat surface formed on a part of an outer circumferential surface thereof, and a cylinder side rotation restricting portion including a groove portion or a projecting portion formed on the outer circumferential surface thereof. The tubular proximal portion has a tube side marking portion including a flat surface formed on an inner surface circumferential surface of the tubular proximal portion, and a tube side rotation restricting portion including a projecting portion projected from the inner circumferential surface or a groove portion formed in the inner circumferential surface.

Abstract: When a male terminal connector (10) and a female terminal connector (50) are engaged with each other, projecting inclined faces (20a) and partition wall inclined faces (59) which are opposed to each other are brought into contact or made opposed to each other, and, fitting projections (61) insert into fitting recesses (21) in such a manner that the fitting projections (61) and the fitting recesses (21) are held with gaps between them.
