いろいろな工夫がなされているが、通常は前部ハンドル
と後部ハンドルを別々に防振し、ハンドルの上下端をチ
ェンソ一本体に直接吸振部材を介して装着している。In order to satisfy these conflicting demands, various measures have been taken to dampen the vibration of the handle, but usually the front and rear handles are vibration-proofed separately, and the upper and lower ends of the handle are directly damped by the main body of the chain saw. It is attached via a member.
この場合は振動を減衰できるが、ハンドルと本体との剛
性が損われ作業性が悪くなる欠点を有する。In this case, although vibrations can be damped, the rigidity of the handle and main body is impaired, resulting in poor workability.
また、剛性を得るために前後両ハンドルが一体に連結さ
れた構造のものもあるが、ハンドルの振動伝達距離が長
くなり、振動を増巾すると共に前部ハンドルを伝わる振
動と後部ハンドルを伝わる振動とが共振を生ずる。In addition, some models have a structure in which both the front and rear handles are connected together in order to obtain rigidity, but this increases the vibration transmission distance of the handle, amplifying the vibration, and vibrations transmitted through the front handle and vibrations transmitted through the rear handle. causes resonance.
本考案は、かへる従来の欠点を解消するために、ハンド

後部ハンドル３はその前頭部８でエンジンユニット本体
１の上側後半部に吸振部材２３を介して結合される。The rear handle 3 is connected at its front part 8 to the upper rear half of the engine unit main body 1 via a vibration absorbing member 23.
該前頭部８は前記前部ハンドル２の上端部６と対面して
配設され吸振部材２５を介して結合される。The forehead 8 is disposed facing the upper end 6 of the front handle 2 and is connected to the upper end 6 of the front handle 2 via a vibration absorbing member 25.
実施例における吸振部材は、合成ゴム等の柱状弾性体を
使用し、該弾性体に直交する方向の剪断応力及び剪断変
形によって振動を吸振せしめている。The vibration absorbing member in the embodiment uses a columnar elastic body such as synthetic rubber, and absorbs vibration by shear stress and shear deformation in a direction perpendicular to the elastic body.
吸振部材の具体的構造の実施例を第４図、第５図に示し
た。Examples of the specific structure of the vibration absorbing member are shown in FIGS. 4 and 5.
第４図のものは前部ハンドルの上端部６と後部ハンドル
の前頭部８との間に介装された比較的大型のものである
が、中空構造として吸振性能を確保せしめている。The one in FIG. 4 is relatively large and is interposed between the upper end 6 of the front handle and the front part 8 of the rear handle, but it has a hollow structure to ensure vibration absorption performance.
また第５図のものは本体１の前部とハンドル結合部材４
との間に介装されたもので、本体１の重量を支える為に
中実構造として強度を持たせている。In addition, the one in Figure 5 shows the front part of the main body 1 and the handle connecting member 4.
It is interposed between the main body 1 and has a solid structure with strength to support the weight of the main body 1.
