Abstract: A vehicle pedal module includes a brake pedal device and an accelerator pedal device. The brake pedal device has a brake pedal first housing configured to rotatably support a brake pedal rotating shaft and to cover a brake-pedal reaction force generation mechanism, and a brake pedal second housing configured to support an end portion of the brake-pedal reaction force generation mechanism opposite to the brake pedal. The brake pedal second housing extends from the brake pedal device to the accelerator pedal device, to have at least a part of the accelerator pedal device fixed thereto, and to be installed on a vehicle body.

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: An air flow measurement device that measures an air flow rate based on an output value of a sensing unit attached in an environment in which air flows, the air flow measurement device is provided. The air flow measurement device may calculate an average air amount, which is an average value of the air flow rate, from the output value. The air flow measurement device may calculate a pulsation maximum value, which is a maximum value of the air flow rate, from the output value.

Abstract: A physical quantity measurement device includes a measurement channel through which the fluid flows to be measured, a physical quantity detector that detects a physical quantity of a fluid in the measurement channel, a housing forming the measurement channel, and a measurement outlet provided in the housing as a downstream end of the measurement channel. An outer peripheral surface of the housing includes an outer peripheral flat surface that extends in an arrangement direction along which an upstream end and a downstream end of the housing are arranged, and an outer peripheral inclined surface inclined with respect to the outer peripheral flat surface and provided between the upstream end and the outer peripheral flat surface in the arrangement direction. The measurement outlet is positioned upstream of the downstream end of the housing.

Abstract: An air flow rate measuring device measures an air flow rate based on an output value of a sensing unit placed in an environment that allows air to flow therethrough. The air flow rate measuring device includes: an acquisition unit configured to acquire the output value; a storage unit configured to store uneven flow information that indicates an uneven flow state of the air in the environment; a pulsation error correction unit configured to correct the air flow rate by using at least one of the uneven flow information and the output value such that the pulsation error Err in the air flow rate caused by the uneven flow becomes smaller.

Abstract: An outlet of a sub passage that returns measured gas, which has passed through a flow sensor, from the sub passage to a main passage opens on an outer wall of a housing toward a downstream side in a reference direction. The outer wall of the housing includes a protrusion on the downstream side of the outlet. When the outlet and the protrusion are projected onto a projection plane perpendicular to the reference direction, the outlet and the protrusion partly overlap with each other on the projection plane. A relationship of θ1

Abstract: A brake device includes a brake pedal, a pedal operation detection section, a tank section, an actuator, a master cylinder, a brake fluid path and a reaction force generating section. The master cylinder includes a cylinder section that forms a storage chamber for storing brake fluid and a piston rod that connects to the brake pedal and pushes out the brake fluid stored in the storage chamber and discharges the brake fluid to an outside of the cylinder section by moving a distance corresponding to an amount of operation of the brake pedal. The brake fluid flow path guides the brake fluid discharged from the storage chamber by being pushed out by the piston rod to the tank section. The reaction force generating section includes an elastic member that generates a reaction force on the brake pedal by elastically deforming according to the amount of operation of the brake pedal.

Abstract: A pedal pad in an organ-type pedal device swings about a predetermined axis when stepped on by a driver's foot. A sensor unit outputs a signal corresponding to a swing angle of the pedal pad. A reaction force generation mechanism has an elastic member that generates a reaction force against a driver's pedaling force applied to the pedal pad. A first housing covers the reaction force generation mechanism, and an opening at least on one side. A second housing is provided on one side of the first housing in a swing direction of the pedal pad. Further, the first housing has a largest opening on a second housing side, which is closed by the second housing and into which the elastic member of the reaction force generation mechanism in a non-bending state is insertable.

Abstract: A flowmeter is disposed in a passage through which a fluid flows. The flowmeter includes a first passage and a second passage. The first passage defines a first opening through which at least a part of the fluid flows into the first passage from the passage. The second passage branches off from the first passage and includes a flow rate detector configured to detect a flow rate of the fluid flowing through the second passage from the first passage. The first passage includes a vortex reducer configured to restrict a vortex from generating.
