とも良好に行えるのである。 That is, as the bearing holder for the power take-off shaft is attached to and removed from the wall of the second transmission case, the end of the power take-off shaft supported by the bearing holder on the side to be inserted into the case is supported by the first transmission case. Since a shaft coupling is used at the end of the transmission shaft to enable it to be connected to and removed from it, the power take-off shaft can be attached to and removed from the second transmission case simply by attaching the bearing holder to the wall of the second transmission case. This can be done by simply attaching and detaching the power take-off shaft to the bearing holder, and if necessary, replacing the power take-off shaft with a different specification can be done by rearranging the power take-off shaft with respect to the bearing holder outside the case. This can be done simply by assembling it to the wall of the second transmission case. Furthermore, the outer circumferential surface of the bearing holder and the inner circumferential surface of the through hole formed in the wall of the second transmission case form a sliding surface that allows the bearing holder to slide freely, and the bearing holder Since the length of the outer circumferential surface in the axial direction of the power take-off shaft is set to be larger than the engagement depth of the portion of the power take-off shaft that engages with the shaft coupling, the power take-off shaft can be inserted into the second transmission case. When installing the bearing holder, before the shaft end is engaged with the shaft coupling, the outer peripheral surface of the bearing holder and the inner peripheral surface of the through hole are used as sliding surfaces to guide the power take-off shaft that moves together with the bearing holder. , the shaft end of the power take-off shaft and the shaft coupling can be easily and quickly engaged. Particularly, according to the present invention, the two bearings for supporting the power take-off shaft are attached in the axial direction to a bearing holder whose dimensions are set to a length sufficient to allow the two bearings for supporting the power take-off shaft to be placed side by side in the axial direction. The power take-off shaft is supported at the top so that the position of the power take-off shaft relative to the bearing holder does not change even if a large external force is applied in the radial direction. It is also possible to transmit the output to various attachment devices with a belt.
