Abstract: A flowmeter is inserted into a main passage through which a target fluid flows. The flowmeter includes a housing, a sub passage, an inlet portion, an outlet portion, a flow rate detector, and a protrusion. The housing includes a side surface and a tip end surface. A part of the target fluid flows into the sub passage from the main passage. The target fluid flows into the sub passage through the inlet portion and flows out of the sub passage through the outlet portion. The flow rate detector is configured to detect a flow rate of the target fluid flowing through the sub passage. The tip end surface includes a first end area and a second end area. The protrusion protrudes from the tip end surface and is located in both the first end area and the second end area.

Abstract: A measurement control device measures an air flow rate using an output value of a sensing portion that outputs a signal according to the air flow rate, and outputs the measurement result of the air flow rate to a predetermined external device. The measurement control device includes: a pulsation state calculator that calculates a pulsation state, which is a state of pulsation generated in the air flow rate, by using the output value of the sensing portion instead of acquiring an output value from an external device; and a flow rate correcting unit that corrects the air flow rate using the pulsation state calculated by the pulsation state calculator.

Abstract: A physical quantity measurement device includes a housing forming a measurement flow path through which the fluid flows and a container space that houses a part of a detection unit. An inner surface of the housing includes a housing intersecting surface that intersects an arrangement direction in which the measurement flow path and the container space are arranged, a housing flow path surface extending from the housing intersecting surface toward the measurement flow path, and a housing container surface extending from the housing intersecting surface toward the container space. The housing includes a housing partition that protrudes from the inner surface toward the detection unit and contacts the detection unit between the housing and the detection unit such that the housing partition separates the measurement flow path and the container space from each other.

Abstract: The present disclosure provides a flow rate measuring device for measuring a flow rate of a main flow flowing through a duct. The flow rate measuring device includes a bypass passage, a blow rate sensor, and a measurement body. The measurement body includes a measurement flow inlet and a cylindrical portion. The measurement flow inlet is open toward an upstream side of the duct. The measurement flow outlet is open toward a downstream side of the duct. The cylindrical portion is disposed to cover the measurement flow outlet. The cylindrical portion includes an outer circumferential surface, which guides the main flow, and an inner circumferential surface, which guides the measurement flow. The cylindrical portion includes a waveform portion that is formed in an edge side of an opening of the cylindrical. The waveform portion has a shape that divides the main flow guided by the cylindrical portion into a plurality of main flows and that divides the measurement flow guided by the cylindrical portion into a plurality of measurement flows.

Abstract: In a brake pedal device, a brake pedal is connected to a casing with a posture changeable by a brake operation of a driver, and includes an operation unit that is pressed by a driver. A reaction force generating unit is provided inside the casing, and the reaction force generating unit is configured to generate a reaction force with respect to the brake pedal in accordance with an amount of change in the posture of the brake pedal during the brake operation, and to cause the brake pedal to return to a reference position when the brake operation is released. A sensor unit is provided outside the casing, to detect an amount of change in the posture of the brake pedal, and a sensor protector is provided at the casing in a position away from the brake pedal, to cover at least a part of the sensor unit.

Abstract: A brake pedal device includes a pedal pad rotatable about an axis when stepped on by a driver, and a reaction force generation mechanism generating a reaction force to the pedal pad according to a stepping amount of the pedal pad. The pedal pad includes a pedal base portion extending away from an axis side end to another end, and a pedal operation portion attached to the pedal base portion and stepped on by the driver. The pedal operation portion protrudes toward a pedal return side in a rotation direction about the axis with respect to the pedal base portion, and a surface of the pedal operation portion has a plane portion that is configured as a flat surface and is stepped on by the driver, so that the reaction force generated by the reaction force generation mechanism acts on the pedal pad in a direction piercing the plane portion.

Abstract: A flowmeter includes a hollow housing, a first passage, a second passage, a detector, and a flat surface. The housing includes a first side wall and a second side wall and defines an inlet opening and an outlet opening that is defined in the first side wall. The first passage fluidly connects between the inlet opening and the outlet opening. The second passage branches off from the first passage. The detector is disposed in the second passage and configured to detect a flow rate of the target fluid flowing through the second passage. The flat surface is an outer surface of the first side wall and extends between an upstream end of the first side wall and the outlet opening along the main flow direction.

Abstract: A physical quantity measurement device includes a housing forming a measurement flow path, a physical quantity sensor that detects a physical quantity of fluid in the measurement flow path, and a sensor support that supports the physical quantity sensor. The sensor support includes a support front surface on which the physical quantity sensor is disposed, and a support back surface behind the support front surface. The housing includes a floor surface facing a support end of the sensor support, a front wall surface facing the support front surface, and a back wall surface opposite to the front wall surface across the floor surface and facing the support back surface. A front distance between the physical quantity sensor and the front wall surface in a front-back direction is larger than a floor distance between the floor surface and the support end in a height direction orthogonal to the front-back direction.
