Patent number: 10377219Abstract: A tractor includes an engine that is mounted on a vehicle body frame, a hood that houses the engine and is configured to pivot about a front pivot in a top-bottom direction between a closed position at which the hood covers the engine, and an open position at which the hood exposes the engine, a mounting rubber that is provided between the engine and the vehicle body frame to support the engine in an anti-vibration manner, and a hood stay that supports the hood such that the hood is pivotable up/down about the front pivot. The hood stay includes an abutting-target portion against which the engine can abut from a rear side, to prevent the engine from swinging forward in a front-rear direction of the vehicle body.Type: GrantFiled: May 26, 2017Date of Patent: August 13, 2019Assignee: Kubota CorporationInventors: Tasuku Teraoka, Takeshi Komorida, Takashi Kumashiro, Shoichiro Nagaishi, Tomohisa Yamamoto, Akihito Mihara, Ryo Matsumoto, Hiroki Nagai, Yuto Akai, Yoshihisa Tonoya, Masaki Takaoka, Tatsuki Kago, Nobuyuki Yamashita, Junichi Yamanaka, Masahiro Izumi, Azusa Furihata, Koichiro Matsumoto, Takashi Shibata

Publication number: 20140211440Abstract: Provided is technology that stably fixes a plurality of harnesses all at once, without using a wire holder. A line-shaping section 30 for routing harnesses 99 is created in a front cabinet forming section 20. The line-shaping section 30 comprises two ribs 40 separated by a prescribed distance and a hook 50 positioned in the center thereof and created so as to cover from the top, when viewed from the side surface. The harnesses 99 held by the ribs 40 and the hook are prevented from being displaced outside, by a hook locking section 54. In addition, routing work for the harnesses 99 is able to be performed smoothly since a sloping surface (a guide section 56) is created in a tip part of the hook locking section 54.Type: ApplicationFiled: May 24, 2012Publication date: July 31, 2014Applicant: SHARP KABUSHIKI KAISHAInventors: Noriyuki Shibuya, Hideaki Nishizawa, Masaya Fujihara, Takashi Kumashiro, Yutaka Yoshizawa, Manabu Shimokobe
