Patent number: 6758181Abstract: A starter which is capable of smoothly and reliably starting an internal combustion engine even though an electric motor employed is relatively small in size and output, thereby making it possible to minimize power consumption of the electric motor, to miniaturize the capacity of battery, to reduce the total weight of the starter, to enhance the durability of the starter, and to suppress the generation of failure of the starter. This starter comprises a buffering/power-accumulating means disposed midway along a power transmission system between a driving member and a driven member, wherein the buffering/power-accumulating means is enabled, during the driving process, to accumulate the power supplied through the driving process while alleviating any impact to the driven member, the accumulated power being subsequently employed to drive the driven member, and wherein the driving member is an electric motor.Type: GrantFiled: January 14, 2002Date of Patent: July 6, 2004Assignee: Kioritz CorporationInventors: Giichi Iida, Junichi Akaike

Patent number: 6105258Abstract: A brake device disposed in the vicinity of a clutch drum has a leaf spring having a brake pad thereon which is brought into slidable contact with the clutch drum. A cam member and a compression coil spring which opposes a cam member with the leaf spring disposed therebetween are provided on a free end of the leaf spring. The cam member is rotated by a rotatable shaft together with a pinion gear which meshes with a rack formed on a stand. When a trimmer is placed on the ground, the stand is moved upwardly and the brake pad is brought into the braking position where the brake pad slidably contacts with the clutch drum. This braking position is released when an operation lever is operated by an operator.Type: GrantFiled: July 13, 1998Date of Patent: August 22, 2000Assignee: Kioritz CorporationInventor: Junichi Akaike
