154号公報)。In this type of rotary tiller, a bearing holder that supports an input shaft is connected by flange to the input-side open end of a molded transmission case to constitute an outer shell portion of the input section. In addition, in order to protect the connecting part of the input shaft from rainwater and dust, a shaft cover that covers the upper part of the input shaft is attached to the bearing holder in a cantilevered manner (Utility Model No. 6147
Publication No. 154).
ところが、上記で引例に挙げたロークリ耕耘装置では、
ベアリングホルダーと伝動ケースとの接合部分が外部に
露出した状態にあるために雨水や埃に露される機会が多
く、接合部分に備えたシールが比較的短期間のうちに損
傷したり、劣化しやすいものであった。However, with the rotary tiller device cited above,
Since the joint between the bearing holder and the transmission case is exposed to the outside, it is often exposed to rainwater and dust, and the seal provided at the joint may be damaged or deteriorated in a relatively short period of time. It was easy.
本発明は、このような実情に鑑みて側基されたものであ
り、その目的は、ベアリングホルダーと伝動ケースとの
接合部分に与える雨水や埃の悪影響を排除することにあ
る。The present invention was developed in view of these circumstances, and its purpose is to eliminate the adverse effects of rainwater and dust on the joint between the bearing holder and the transmission case.
本発明の特徴構成は、軸カバーに、ベアリングホルダー
と伝動ケースとの接合部を覆うフランジカバー部を一体
連設しである点にあり、その作用・効果は次の通りであ
る。A feature of the present invention is that the shaft cover is integrally provided with a flange cover portion that covers the joint between the bearing holder and the transmission case, and its functions and effects are as follows.
つまり、軸カバーに一体連設されたフランジカバー部が
、ベアリングホルダーと伝動ケースとの接合部を覆って
水や埃がシールに作用するのを防止するのである。In other words, the flange cover part integrally connected to the shaft cover covers the joint between the bearing holder and the transmission case to prevent water and dust from acting on the seal.
その結果、接合部分のシールが雨水や埃の影響で早期に
損傷したり劣化するのを極力防止して耐食性の高いもの
になった。As a result, the seals at the joints are highly resistant to corrosion by preventing early damage or deterioration due to the effects of rainwater and dust.
