Abstract: Provided is a canister configured to adsorb and desorb an evaporated fuel originating in a fuel tank of a vehicle. The canister includes an outer case, a coupling port, an inner case, and at least one first protrusion. The outer case includes an inner surface defining an internal space extending in a first direction. The coupling port couples an inside and an outside of the outer case. The inner case is a cylindrical member accommodating therein an adsorbent for adsorbing the evaporated fuel. The at least one first protrusion protrudes outwards from an outer surface of the inner case. A fluid flows through the internal space in the first direction. The inner case is press-fitted inside the outer case so as to be accommodated in the internal space. The at least one first protrusion contacts a part of the inner surface of the outer case extending in the first direction.

Abstract: A method of manufacturing a pipe extending along an axis of the pipe includes forming a blank material into a U-shaped member that extends along the axis and has a cross-section of U-shape, and forming the U-shaped member into a shape of the pipe. The pipe includes a large-diameter portion, a small-diameter portion, and a gradually-reduced-diameter portion. The gradually-reduced-diameter portion connects the large-diameter portion and the small-diameter portion to each other. In the method of manufacturing the pipe, at least one bead extending along the axis of the pipe is formed in a part, of the blank material or the U-shaped member, that corresponds to the gradually-reduced-diameter portion.

Abstract: One aspect of the present disclosure provides a canister configured to adsorb and desorb fuel vapor generated in a fuel tank of a vehicle. The canister includes a charge port configured to take in the fuel vapor, a purge port configured to release the fuel vapor, an atmosphere port open to an atmosphere, a first adsorption chamber and a second adsorption chamber directly coupled to the charge port and the purge port or indirectly coupled to the charge port and the purge port via an additional chamber, a first adsorption member housed in the first adsorption chamber, and a second adsorption member housed in the second adsorption chamber. The first adsorption member includes two or more adsorption layers having properties to adsorb the fuel vapor and an adjustment layer having an air-permeability and interposed between the two or more adsorption layers.

Abstract: A first joining member configured to be used to join an instrument panel reinforcement to a vehicle body includes upper and lower body fastening surfaces to be fastened to the vehicle body. The first joining member is configured to be able to hold the instrument panel reinforcement between the upper and lower body fastening surfaces. There is defined an imaginary line that is orthogonal to an imaginary plane connecting the upper and lower body fastening surfaces, and passes through a center axis, extending in a vehicle-width direction, of the instrument panel reinforcement held by the first joining member. A distance along the imaginary line from the center axis to the imaginary plane is equal to or shorter than a distance along the imaginary line from the center axis to an outer circumferential surface of the instrument panel reinforcement.

Abstract: Provided is an evaporated fuel treatment device. The evaporated fuel treatment device includes a main body case and a lid. The lid includes a target port, and is configured to be attached to the main body case on an attachment surface defined in advance in the main body case. The target port is configured to guide a gas in a direction intersecting a flow direction of the gas in a target adsorption chamber. The lid is configured to be rotated along a rotation direction prior to being attached to the main body case, to thereby (i) allow selection of one attachment angle from two or more attachment angles and (ii) be attached to the main body case.

Abstract: The present disclose provides a method of resistance spot welding that can inhibit Liquid Metal Embrittlement-induced cracking in zinc-coated steel plates irrespective of the plate thicknesses. One aspect of the present disclosure provides a method of resistance spot welding that includes welding a workpiece with a resistance spot welding apparatus. The workpiece includes two or more steel plates in an overlapping state. The two or more steel plates include at least one steel plate coated with zinc. The welding includes causing a cooling rate of a high-tensile steel plate among the two or more steel plates to be higher than a cooling rate of an other steel plate among the two or more steel plates. The high-tensile steel plate has a tensile strength higher than a tensile strength of the other steel plate.

Abstract: A pipe extending from a first side toward a second side includes a side wall and a spool. The spool formed in the side wall is bent so as to protrude from an outer circumferential surface of the pipe, and extends to surround the outer circumferential surface. The spool includes a first portion located on the first side and a second portion located on the second side. There is a clearance between the first portion and the second portion in a top region of the spool, and the first portion and the second portion substantially abut each other in a base region.

Abstract: One aspect of the present disclosure provides a muffler including an exhaust pipe and a space forming member. The exhaust pipe has a cylindrical shape having a flow passage inside through which exhaust gas passes. The space forming member forms closed spaces between itself and the exhaust pipe, the closed spaces being branched from the flow passage and adjacent to the flow passage. Each of the closed spaces and the flow passage communicate with one another via a single communication hole.
