Abstract: A brake device for a vehicle includes: a brake pedal having a pedal portion and a lever portion that rotates about a rotation axis when the pedal portion is operated; a housing that rotatably supports the lever portion; and a plate member configured to generate a reaction force with respect to the lever portion in response to a stroke amount of the brake pedal. The plate member has a longitudinal surface defined by a side extending in a longitudinal direction of the plate member and a side extending in a width direction of the plate member. The longitudinal surface is arranged so as to face the lever portion. When the pedal portion is operated, the plate member is bent to generate the reaction force.

Abstract: A centrifugal pump includes a motor having a shaft, and an impeller engaged with an end portion of the shaft such that a rotation of the impeller relative to the shaft is limited. The impeller includes a main panel engaged with the shaft, a plurality of passage walls extending from the main panel in an axial direction, a side panel in contact with end surfaces of the passage walls that face away from the main panel, the side panel having an inflow opening at a radially center part, and a fluid passage that is defined by the passage walls adjacent to each other in a circumferential direction, the fluid passage communicating with the inflow opening. The side panel includes an engagement portion configured to be engaged with a fixation jig that limits a rotation of the impeller during fixing the impeller to the shaft by screwing a nut.

Abstract: A purge pump is installed in a purge conduit, which forms a purge passage that communicates between an inside of a canister and an air intake passage. When a pressure of the air intake passage is equal to or smaller than a predetermined pressure, a large quantity of evaporative fuel, which is larger than a predetermined purge quantity, is introduced into the air intake passage. At this time, a pump electric power supply device supplies a relatively small amount of the electric power to the purge pump to run the purge pump. When the pressure of the air intake passage is larger than the predetermined pressure, the purge pump is driven to pump the evaporative fuel into the air intake passage. At that time, the pump electric power supply device supplies a relatively large amount of the electric power to the purge pump.
Abstract translation: 清洗泵安装在净化管道中，净化管道形成在罐的内部和进气通道之间连通的净化通道。 当进气通道的压力等于或小于预定压力时，大于预定清洗量的大量蒸发燃料被引入进气通道。 此时，泵电源装置向清洗泵供给相对少量的电力来运行净化泵。 当进气通道的压力大于预定压力时，驱动净化泵将蒸发燃料泵送到进气通道中。 此时，泵电力供给装置向净化泵供给比较大量的电力。

Abstract: A centrifugal pump for pressurizing fluid by using centrifugal force has an impeller and a casing. The impeller is operated rotatably by an actuator. The casing houses the impeller. The impeller has blades arranged one after another in a circumferential direction of the impeller, and a passage is defined between the blades adjacent to each other in the circumferential direction. The passage has a linear portion and a curved portion. The linear portion extends linearly and has a uniform cross section. The curved portion is connected to an end of the linear portion, extends as being curved to a radial-outer side of the impeller, and decreases in cross section toward the radial-outer side.
