る。(Prior Art) FIG. 9 is a sectional view showing a clutch side cover of a conventional hoisting device used for a crane, FIG. 10 is a VV sectional view of FIG. 9, and 1 is a cylindrical portion at one end. A drum provided with 2 is a motor 3 for rotating a drum with a speed reducer, 4 is a shaft rotated by the motor 3, and 5 is a clutch for transmitting the rotational force of the shaft 4 to the drum 1. A clutch driver 5a for contacting and disengaging the clutch lining 6 is provided around the circumference. Reference numeral 7 is a brake band that comes into contact with and separates from the inner circumference of the cylindrical portion 2, 8 is a cover that prevents rainwater from entering the brake band 7 and the clutch lining 6, and the cover 8 has an upper cover 9 and a lower part. It consists of a cover 10.
The upper cover 9 includes a top plate portion 11 and a cylindrical portion 2 of the drum 1.
The inner side of the winding drum side plate 12 is inserted into the groove 2a provided in the outer side of the shaft in a non-contact manner, and the inner side of the motor side plate 13 faces the shaft 4 with a gap g. The lower cover 10 has a winding drum side plate 14 whose inner circumference is inserted in a groove 2a provided on the outer circumference of the cylindrical portion 2 of the drum 1 in a non-contact manner, and an inner circumference having a gap g on the shaft 4. It is composed of a motor-side side plate 15 facing each other, and the joints between the side plates 13 and 15 of the upper and lower covers are closed by a coupling plate 16. These upper and lower covers 9 and 10 are attached by bolts 19 to stays 17 and 18 fixed to the base of the apparatus.
