Abstract: A brake device includes: a brake pedal including a pedal and a lever that rotates about a rotation axis when the pedal is operated; a housing that rotatably supports the lever; a reaction force generator that generates a reaction force to the lever in accordance with a stroke amount of the brake pedal by receiving a force from the lever when the brake pedal is operated; a deformation member including a deformation portion that is deformed by a force received from the lever when the brake pedal is operated in a state where the reaction force generated by the reaction force generator is generated; and a stroke sensor that outputs a signal corresponding to the stroke amount and outputs a value indicating that operation of the brake pedal is abnormal and instructing execution of control for stopping a vehicle when the deformation portion is deformed.

Abstract: A brake device for a vehicle includes: a brake pedal having a pedal part and a lever part that rotates about a rotation shaft when the pedal part is operated; a housing that rotatably supports the lever part; a reaction force generator connected to the housing and the lever part to generate a reaction force against the lever part according to a stroke amount of the brake pedal; and a stopper configured to stop the lever part by being in contact with the lever part such that the lever part is restricted from rotating in a direction opposite to a rotation direction when the pedal part is operated.

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 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 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: 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.
