Abstract: A turbocharger includes a FIGwastegate valve, an actuator for the wastegate valve, and a link mechanism linking the wastegate valve with the actuator via a specific rod. A plate is a component of the link mechanism and connects the wastegate valve with the rod or connects the rod with the actuator. The plate includes a body portion in a plate shape and a pin portion protruding from the main body portion. The pin portion is in a tubular shape having a hollow portion opened to its outside. The pin portion is engageable with an other component of the link mechanism on its outer periphery to form a rotation axis of the other component.

Abstract: A first rod is rotatably connected to a first drive lever shaft and a first valve lever shaft. A second rod is rotatably connected to a second drive lever shaft and a second valve lever shaft. A first predetermined shape portion is formed at a location, which is spaced from an axis of an output shaft by a predetermined distance. A second predetermined shape portion is formed in a second drive lever and is contactable with the first predetermined shape portion. A spring is placed between the actuator and the second drive lever and urges the second drive lever in a predetermined direction, which coincides with a closing direction of a second valve and an approaching direction of the second predetermined shape portion toward the first predetermined shape portion.

Abstract: A pedal pad includes a tread portion depressed by a driver, is fixed to a pad holder, and is displaced together with the pad holder with respect to a support when depressed. A load sensor is fixed to the pad holder and detects a pedal effort of the driver acting on the pedal pad. A pedal effort transmission member includes a pressing portion that presses the load sensor to transmit the pedal effort to the load sensor, and is placed between the tread portion and both the load sensor and the pad holder, and pressed by the tread portion. The pedal pad holds the pedal effort transmission member against the pad holder so that the pressing portion is pressed against the load sensor by the elastic deformation of the pedal pad when the depression operation is not performed.

Abstract: A pedal device includes: a pedal configured to rotate about a rotational axis; and a reaction force generator configured to generate a reaction force corresponding to an urging force generated by pressing operation of the pedal. The pedal includes an urging portion configured to transmit the urging force to the reaction force generator when the urging portion is rotated integrally with the pedal. The reaction force generator includes a linearly moving portion configured to move linearly in an extending direction of a central axis of the reaction force generator when the pressing operation is performed. The urging portion has an urging surface configured to urge a contact surface of the linearly moving portion. The urging portion is placed at a position where a virtual urging center passes through a virtual axis perpendicular line when the pedal is rotated within a predetermined rotational range.

Abstract: A pedal device mounted on a vehicle includes a housing, a pedal pad, and a reaction force generation mechanism. The housing is mounted on a vehicle body. The pedal pad is provided to be rotatable with respect to the housing. The reaction force generation mechanism is configured to include a plurality of resilient members each having a predetermined leaf spring. The reaction force generation mechanism is arranged in a space on the side opposite to a surface stepped on by a driver in the pedal pad to generate a reaction force against a pedaling force applied to the pedal pad by the driver.

Abstract: A brake pedal is operated by a pedal force of a driver. A sensor is capable of detecting a stroke amount of the brake pedal. A brake circuit generates braking force to apply a brake to a vehicle by applying hydraulic pressure to wheel cylinders provided to respective wheels. An electronic control device controls the braking force generated by the brake circuit based on an output signal from the sensor and a state of the vehicle. The electronic control device executes predetermined braking force control under which the braking force generated by the brake circuit is set to be predetermined braking force, when the stroke amount of the brake pedal is between a first threshold and a second threshold larger than the first threshold.

Abstract: A brake device for a brake-by-wire system includes a brake pedal, a sensor, a reaction force generator, and a reaction force changing mechanism. The brake pedal is rotatably mounted on a housing and not mechanically connected to a hydraulic pressure generator. The sensor outputs a signal corresponding to a stroke amount of the brake pedal to an electronic control unit. The reaction force generator has one end connected to the brake pedal and the other end connected to the housing so as to generate a reaction force against a depression force applied to the brake pedal by a driver. The reaction force changing mechanism generates a reaction force against a depression force applied to the brake pedal by the driver, and is able to change a magnitude of the reaction force in advance according to the driver.

Abstract: An output gear includes a fixing portion, which is joined to a surface-processed portion of an output shaft, and a connecting portion that connects between a toothed portion of the output gear and the fixing portion. A length, which is measured from a center of a boundary surface between the connecting portion and the fixing portion in an axial direction of an axis of the output shaft to one end part of a joint between the surface-processed portion and the fixing portion on a linkage mechanism side along the joint, is indicated by L1. A length, which is measured from the center of the boundary surface to an opposite end part of the joint that is opposite to the linkage mechanism in the axial direction, is indicated by L2. A relationship of L1>L2 is satisfied.
