Patent number: 8607904Abstract: A working vehicle is structured to maintain a ride quality for an operator on a control seat. Provided are a travel machine body which mounts an engine, front wheels on the machine body, a track frame on the machine body, right and left travel crawlers installed on the track frame, a rear axle which transmits a rotating force to the travel crawler, and oscillation supporting point shafts which support the track frame on the machine body so as to freely oscillate. In the case that the rear axle and the oscillation supporting point shafts are provided so as to be spaced, the oscillation supporting point shafts are arranged just below an axle case to which the rear axle is pivoted, and the track frame is connected to the axle case via link members provided in the oscillation supporting point shafts.Type: GrantFiled: August 30, 2011Date of Patent: December 17, 2013Assignee: Yanmar Co., Ltd.Inventors: Takeshi Fukumoto, Keisuke Iwamura, Shinya Kawashiri

Patent number: 8371408Abstract: A bonnet structure including a bonnet flange extending inward from an inner peripheral surface of a bonnet is positioned farther toward a first direction, which is opposite in a vehicle longitudinal direction to a rotary shaft for the bonnet, than shroud flanges extending outward from side surfaces of a shroud main body when the bonnet is located at a closed position. A first elastic sealing member mounted to the bonnet flange is brought from the first direction into contact with anteroposterior contact surfaces of the shroud flanges that face to the first direction when the bonnet is rotated about the rotary shaft from the opened position to the closed position. It is possible to effectively prevent an excessive abrasion and a detachment of elastic sealing members for sealing a gap between the bonnet and the shroud.Type: GrantFiled: December 10, 2009Date of Patent: February 12, 2013Assignee: Yanmar Co., Ltd.Inventors: Shinya Kawashiri, Yutaka Matsui

Patent number: 8336952Abstract: A waterproof structure for outer roof includes a sealing plate fixed to an upper frame so as to form a cabin member, a first elastic sealing member sandwiched between the cabin member and the outer roof, and a second elastic sealing member attached to the outer roof. The first elastic sealing member is sandwiched between the outer roof and the cabin member to form a first sealing portion that seals the inner space of the cabin from the outside. A sealing site of the second sealing member is pressed against an outward extending region to form a second sealing portion that seals the inner space of the cabin from the outside at a position outside the first sealing portion. The present invention can enhance waterproof property as well as quality in outer appearance.Type: GrantFiled: February 23, 2010Date of Patent: December 25, 2012Assignee: Yanmar Co., Ltd.Inventor: Shinya Kawashiri

Patent number: 8312955Abstract: A working vehicle according to the present invention includes a pair of front frames and a pair of main frames that are detachably connected to each other, a reinforcing member coupling the pair of main frames while being overlapped therewith in a side view, a pair of attachment stays fixedly attached to outer side surfaces of the pair of main frames so as to be at least partially overlapped with the reinforcing member in a side view. A cabin is supported in a vibration-isolation manner at no less than four positions including the pair of attachment stays and right and left supporting positions that are provided at a pair of rear axle cases or a transmission case. The working vehicle can enhance stabilization of support of the cabin while simplifying a structure.Type: GrantFiled: January 5, 2010Date of Patent: November 20, 2012Assignee: Yanmar Co., Ltd.Inventor: Shinya Kawashiri
