Abstract: A steering device includes a cylindrical steering column that extends in an axial direction. The steering column includes: an upper column; a lower column; and a fixing member. The fixing member includes a cylindrical part, and the cylindrical part includes: a small diameter part that is fitted to the lower column; a curved part that has an outer circumferential surface whose outer diameter increases toward the other side in the axial direction; and a large diameter part whose outer diameter is larger than an outer diameter of the small diameter part.

Abstract: A steering device includes: a steering shaft which extends along a central axis and to which a steering wheel is coupled on one side in an axial direction; a tubular steering column which is disposed on an outer circumferential side of the steering shaft and extends in the axial direction; and a gearbox which is disposed on the other side in the axial direction of the steering column and is fixed to the steering column. The steering column includes a fixing member provided at an end on the other side in the axial direction and fixed to the gearbox, and an outer circumferential surface on one side in the axial direction of the fixing member has an outer diameter which increases toward the other side in the axial direction.

Abstract: A damper device includes a plurality of rotational elements including an input element and an output element; an elastic body that transmits a torque between the input and the output elements; and a rotary inertia mass damper with a mass body rotating in accordance with a relative rotation between a first rotational element which is one of the rotational elements and a second rotational element different from the first rotational element. The rotary inertia mass damper includes a sun gear that rotates integrally with the first rotational element, pinion gears rotatably supported by the second rotational element, and a ring gear that meshes with the pinion gears and works as the mass body. The second rotational element includes a plurality of ring gear supporting portions arranged at intervals in a circumferential direction so as to restrict a movement of the ring gear in an axial direction of the damper device.

Abstract: An exhaust apparatus for an internal combustion engine includes a first exhaust collecting section, a first exhaust passage, a first exhaust sensor, and a rib. The first exhaust passage is connected to the first exhaust collecting section and has a curved shape to change a flow direction of the exhaust gas from a direction in which the exhaust gas is ejected from each of first cylinders. The first exhaust passage includes an outer wall provided on a radially outer side of the curved shape. The rib is provided on the outer wall of the first exhaust passage and extends along a direction perpendicular to a direction in which the exhaust gas flows. The rib is positioned downstream from the first exhaust sensor.
