Patent number: 8562238Abstract: A pipe handle holding structure wherein force for holding a bar handle in a holder is minimized, the holding performance whereby the bar handle is held by the holder is improved, and the bar handle and holder are maintained in an appropriate state even in cases in which the bar handle is frequently attached to and detached from the holder. The pipe handle holding structure comprises a round pipe-shaped bar handle, and a holder for holding an external peripheral surface of the bar handle. The holder has a plurality of concealing parts for concealing the external peripheral surface of the bar handle and elastically deforming the external peripheral surface in a pipe diameter direction.Type: GrantFiled: December 1, 2009Date of Patent: October 22, 2013Assignee: Honda Motor Co., Ltd.Inventors: Shoji Hasei, Mai Ohba, Katsuhisa Ichikawa, Kouhei Okaguchi

Patent number: 8215090Abstract: A walk-behind work machine in which vibration produced by the driving of an engine is not readily transmitted to an operating handle. The work machine includes a work-machine body having a plurality of mounting parts to which an engine is joined. The mounting parts include a high-rigidity mounting part positioned at a maximally rigid part on the work-machine body, and other mounting parts exclusive of the high-rigidity mounting part. The engine is joined securely to the other mounting parts and is joined more loosely to the high-rigidity mounting part than to the other mounting parts.Type: GrantFiled: March 16, 2011Date of Patent: July 10, 2012Assignee: Honda Motor Co., LtdInventors: Tomoaki Ishikawa, Mai Ohba, Shuhei Maruyama, Jitsumi Hanafusa

Patent number: 8166737Abstract: A walk-behind lawnmower having a height adjusting mechanism for adjusting the height of a housing above the ground. The height adjusting mechanism includes: a front wheel supporting member and a rear wheel supporting member that are attached to the housing so as to be capable of swinging up and down; a linking member for linking the front and rear wheel supporting members so as to be capable of concerted motion; and a locking mechanism for restricting and releasing displacement of the linking member in the forward-and-backward direction. The locking mechanism includes: a plurality of locking grooves arranged in a row from front to rear on the linking member; a locking pin capable of selectively interlocking with one of the locking grooves; a pin-guiding part for guiding the locking pin to be capable of entering into and retracting from one of the locking grooves; and an operating member for sliding and operating the locking pin.Type: GrantFiled: March 29, 2011Date of Patent: May 1, 2012Assignee: Honda Motor Co., Ltd.Inventors: Yusuke Ninomiya, Tetsuo Iida, Nobuyuki Hirose, Mai Ohba
