Abstract: An embodiment provides a vane pump device. In the vane pump device, vane grooves of a rotor include columnar grooves which accommodate oil, and support the vanes. An inner-plate low pressure side recess portion is provided in an end surface of an inner plate along a rotation direction, and supplies oil to the columnar grooves. An outer-plate low pressure side through-hole and an outer-plate low pressure side recess portion are provided in an end surface of an outer plate along the rotation direction, and supply oil to the columnar grooves at a position facing the inner-plate low pressure side recess portion. An opening area of the inner-plate low pressure side recess portion is equal to a sum of opening areas of the outer-plate low pressure side through-hole and the outer-plate low pressure side recess portion.

Abstract: A clutch for use in a steer-by-wire steering device for a vehicle is configured to switch between mechanically coupling and uncoupling a torque transmission path between a steering member operated by a driver and a wheel-turning unit configured to turn wheels. The clutch includes a position change member and a conduction path. The position change member is configured to change between a first position and a second position to switch between mechanically coupling and uncoupling the torque transmission path. The conduction path includes two points that come into contact with or separate from each other in accordance with positional change of the position change member. The conduction path is connected to an electric circuit configured to detect a change in a resistance value of the conduction path.

Abstract: Disclosed is a vane pump device including: an even number of vanes; a rotor; a cam ring; an inner plate; and an outer plate. An inner-plate high pressure side through-hole and an inner-plate low pressure side recess portion are formed separately from each other in a rotation direction in cam ring side end surfaces of the inner plate and the outer plate, and communicate with a columnar groove which is a space of a vane groove on a rotation center side. The position of an inner-plate high pressure side through-hole upstream end and the position of an inner-plate low pressure side recess portion upstream end are point-symmetrical with each other with respect to the rotation center.

Abstract: An inner-plate cam ring side recess portion is formed in a cam ring side end surface of an inner plate, communicates with a columnar groove which is a center side space in a vane grooves, and supplies a working fluid to the columnar groove. The inner-plate cam ring side recess portion is divided into multiple sections between a first side discharge port, through which the working fluid is discharged at a first discharge pressure from a pump chamber, and a second side suction port through which the working fluid is suctioned into a pump chamber discharging the working fluid at a second discharge pressure. An angle of a separation portion in a rotation direction is smaller than or equal to an angle between the first side discharge port and the second side suction port.

Abstract: A pressure damping device includes a cylinder, a partitioning section, a flow channel formation section, a valve section a bypass channel and a throttle section. The flow channel formation section forms a flow channel, through which the fluid flows, in conjunction with a movement of the partitioning section. The valve section controls a flow of the fluid in the flow channel of the flow channel formation section. The bypass channel forms a flow of the fluid that bypasses the flow of the fluid flowing through the flow channel while opening the valve section. The throttle section that throttles the flow of the fluid through the bypass channel further on an outer side than the valve section with respect to the flow channel formation section.
