ケース３の高さを低くしても、くびれ部３Ａによ
つて締結具６０の締結弛緩ができる。 In addition, a fitting part 35 is formed on the gear 32 of the gear transmission mechanism 25 of the second transmission case 4, and the output shaft 20 of the first transmission case 3 is inserted and connected to this fitting part 35 in a freely insertable and removable manner. During assembly, the output shaft 20 can be used for centering, and the mounting seat 10 and the receiving seat 58 can be superimposed and attached and fixed easily and accurately, ensuring assembly accuracy. gear noise can also be significantly reduced. Further, the first transmission case 3, which has the power receiving shaft 13 and the power output shaft 20 orthogonally arranged, has a constricted portion 3A on the side corresponding to the power receiving shaft 13 above the mounting seat 10 at the lower end thereof. Even if the height of the first transmission case 3 is reduced by forming the constricted portion 3A, the fastener 60 can be tightened and loosened.

高さ方向にコンパクトに組付けることができる。 Also, inside the second transmission case 4 is a bearing case 30 of the bevel gear mechanism 25 that protrudes upward from the lower surface.
is formed, and since the protruding end of the bearing case 30 is located above the overlapping surface of the mounting seat 10 and the receiving seat 58, it can be assembled compactly in the height direction together with the constricted portion 3A. Can be attached.
