ス１に多数のポルｌ−８で固定する。To explain this invention with reference to the embodiments shown in the attached drawings, in FIGS. 1 and 2, the bow side of the propeller boss 1 is integrated, and a neck-like structure is formed between the propeller boss blade 2 and the base end flange 6. A sliding part 3 is provided, and two arc-shaped bearing metals 4, 4 are fitted to the outer periphery of the sliding part 3 to form a propeller base, and the propeller base is fitted into the blade attachment hole of the propeller boss 1. Inserted,
Next, a two-split arc-shaped fixing ring 7,7' is inserted between the base flange 6 and the bearing metals 4, 4', and in this case, the fixing ring 7' is located on the bow side, and the fixing ring 7 is on the stern side. and fixing ring 7.7' and bearing metal 4
.
又プロペラボス１の船尾側にボスキャップ１９をねじ嵌
合２０する。Further, a boss cap 19 is screwed 20 onto the stern side of the propeller boss 1.
又前記基端フランジ６にクランクピン１０をボルト５で
゛固着する。Further, a crank pin 10 is fixed to the base end flange 6 with bolts 5.
なお図中９はＯリング、２７はガイドブロックを示す。In the figure, 9 indicates an O-ring, and 27 indicates a guide block.
本考案は以上の構成であり、固定リング７．７′と軸受
メタル４，４′を嵌入又は抜き取り、かつ固定リング７

ロペラ羽根２の分解、組立が簡易である。The present invention has the above-mentioned configuration, and the fixing ring 7, 7' and the bearing metals 4, 4' are inserted into or removed from each other, and the fixing ring 7.
．． Since the propeller blade 7' and the bearing metals 4 and 4' are divided into two parts, disassembly and assembly of the propeller blade 2 are easy.
又軸受メタル４が摩耗した時には第４図の例のようにボ
ス全体が交換する必要がなく、単に軸受メタル４を交換
することにより精度が復元できる。Furthermore, when the bearing metal 4 becomes worn, there is no need to replace the entire boss as in the example shown in FIG. 4, and accuracy can be restored by simply replacing the bearing metal 4.
又軸受メタルの材質は従来には耐触性材料が必要であっ
たが、本考案では一般構造用鋼材の使用が可能となって
いる。In addition, the material of the bearing metal conventionally required a corrosion-resistant material, but the present invention allows the use of general structural steel.
