Abstract: A handlebar assembly including: an upper bracket rotatable with a steering shaft; a handlebar extending in a left-right direction; a handle holder supporting the handlebar and including: a pair of handlebar supporting sections positioned respectively on left and right sides of the steering shaft, a main body positioned away from the handlebar supporting sections in an up-down direction view, and a pair of connecting arm sections connecting the handlebar supporting sections to the main body; a pair of supporting connecting sections connecting the handlebar supporting sections to the upper bracket, where the handle holder is displaceable in the up-down and/or lateral direction; and a body connecting section connecting the main body to the upper bracket. A distance between each of the supporting connecting sections and the body connecting section, in the up-down direction view, is greater than a sum of a width and a thickness of each connecting arm section.

Abstract: After a glass sheet (G) having a scribe line (S) formed thereon is placed on a placement table (10) and positioned so that the scribe line (S) is positioned in a bending stress applying portion (15) of the placement table (10), when the glass sheet (G) is split along the scribe line (S) by applying a bending stress to a formation region of the scribe line (S) by the bending stress applying portion (15), the glass sheet (G) is positioned by laying a resin sheet (9) under the glass sheet (G) on the placement table (10) and aligning one side (G1) of the glass sheet (G) extending in a direction along the scribe line (S) with marks (Ma to Nd) projected onto a protruding portion (9a) of the resin sheet (9) by laser markers (16a to 16d).

Abstract: A method of manufacturing a glass sheet includes a start point forming step of forming a scribe line on a preset cutting portion of a glass sheet, a setting step of causing, through use of a support member having a groove-shaped recess, the support member to support the glass sheet having the scribe line formed thereon from one surface side so that the preset cutting portion is arranged on the recess, and a cutting step of generating a negative pressure in the recess to bend the preset cutting portion on the recess so that the one surface side protrudes, to thereby cut the glass sheet along the preset cutting portion with the scribe line as the start point. At the time of performing the cutting step, the entire recess is covered with a cover member from another surface side of the glass sheet through intermediation of the glass sheet.

Abstract: A leaning vehicle including a vehicle body, two front wheels, and a support mechanism by which the two front wheels are supported by the vehicle body. The support mechanism includes a joint mechanism that is a ball joint and that includes a ball stud including a ball part connected to a shaft, and a holder having an open end part through which the ball stud is insertable, such that the ball part is freely rotatable in the holder. The open end part includes first to fourth inner edge parts. When the ball stud is in a steering neutral and leaning neutral position, in a direction along a central axis of the ball stud, the first and second inner edge parts do not overlap, and the third and fourth inner edge parts overlap, the ball part. The ball stud is tiltable between the first and second inner edge parts.

Abstract: In a leaning vehicle, a shock absorber tower is disposed further forward in a vehicle-body-frame frontward direction than an upper-left-arm-member supported part at which an upper-left arm member to which a first end part of a left shock absorber is connected is supported by the vehicle body frame, and an upper-right-arm-member supported part at which an upper-right arm member to which a first end part of a right shock absorber is connected is supported by the vehicle body frame.

Abstract: An increase in the size of a leaning vehicle that has a double wishbone-type link mechanism is suppressed. A caliper is supported by a vehicle body frame. A disk includes: a disk contact part with which pads are allowed to be brought into contact; and a disk support part that, when the vehicle body frame is in an upright state, is supported by a support arm at a position that is further upward in an upward direction than an arm central shaft. When seen from a frontward direction, the disk support part supports the disk contact part so that an arm passing region through which a portion located between the arm central shaft in the support arm and a second end part of a left shock absorber and a second end part of a right shock absorber passes overlaps with the pads.

Abstract: A glass roll includes a glass film formed by a downdraw method. The glass film is wound into a roll using a winding roller in a state in which front and back glass surfaces of the glass film formed in the forming operation are exposed, and during the winding operation, the glass film is superposed on a separable protective sheet. The protective sheet extends beyond both sides in a width direction of the glass film. The protective sheet can further be wound on an outer peripheral surface of the glass film by winding only the protective sheet from a trailing end of the glass film in a winding direction of the glass film.

Abstract: A glass roll reliably prevents a glass film from breaking from an end surface of the glass film as an origin of breakage. The glass roll is formed by winding the glass film into a roll while superposing the glass film on a protective sheet. The glass film is formed by an overflow downdraw method to have a thickness of 1 ?m or more and 200 ?m or less, and has each end surface in a width direction formed as a cut surface cut by laser splitting.

Abstract: A method of producing a glass film includes forming an inorganic thin film on a surface of a supporting glass so that a surface of the inorganic thin film after being formed has a surface roughness Ra of 2.0 nm or less after film formation, and forming a glass film laminate by laminating a glass film having a surface roughness Ra of 2.0 nm or less on the surface of the inorganic thin film in a state of being in contact with each other. The method also includes carrying out treatment involving heating with respect to the glass film laminate, and peeling off the glass film from the supporting glass after the treatment involving heating.

An adhesive force between the supporting glass and the glass film is greater at the second region than at the first region.
