Abstract: The present disclosure provides a foam molded product and a manufacturing method. The foam molded product is includes a foam body, an insert material having a display unit or a detection unit attached to the foam body, and a surface material affixed to a surface to which at least the insert material is attached. A manufacturing method includes: preparing a pair of molds including a first mold and a second mold; affixing an insert material and a surface material together such that the surface material is in contact with a molding surface of the first mold; closing the pair of molds; injecting a foam resin into a molding space formed by closing the molds; foaming the foam resin to form a foam body; opening the pair of molds; and removing a molded product in which the affixed part and the foam body are integrated.

Abstract: A steering device according to an aspect of the present disclosure includes a column unit, a front bracket, a rear bracket, and a lock mechanism. The lock mechanism includes a rod supported by the column unit so as to be movable in a vertical direction in tilt guide holes in an unlocked state, and an operation portion that is fixed to a first side end portion of a rod in a right-left direction and that is used to operate of the rod. The first through-hole includes a first straight portion and a first tapered portion. The second through-hole includes a second straight portion and a second tapered portion.

Abstract: A piston 1 is employed in an engine 50 where a tumble flow is generated within a combustion chamber 53. The piston 1 includes: a top ring channel 3; and a portion 10 of an outer circumferential portion of a top surface, the portion 10 positioned opposite to an adjacent cylinder of the engine 50, the portion 10 having a raised shape so as not to expose a position P, of a bore wall surface, facing the top ring channel 3 face in the top dead center during at least a period from a time when the piston 1 is positioned at a compression top dead center to a time when a quantity of heat transfer in the combustion chamber 53 is the highest.

Abstract: In a low load region where torque is lower than T1 but is not lower than T2, the present invention uses a lean single valve small operating angle mode to provide a lean burn in a single valve small operating angle state or uses an EGR single valve small operating angle mode to provide external EGR in a single valve small operating angle mode.
