<P>PROBLEM TO BE SOLVED: To provide a joint part structure of an industrial device which does not tend to lose drive torque and can effectively prevent the liquid component of grease or lubricant from leaking to the outside despite the considerably low cost. <P>SOLUTION: In this joint part structure, grease is contained in the circular recess 10a of a first frame 10, a speed reducer 12 is installed to reduce the rotational speed of a servo-motor 13 and transmit the reduced speed to a rotating body 14, and the outer ring 15a of a bearing 15 is fixed. The rotating body 14 fixed to a second frame 11 is connected to the inner ring 15b of the bearing 15 so as to support rotatably. A first cylindrical wall 16 is provided integrally to the outer periphery of the circular recess 10a of the first frame 10, and a band-shaped first felt member 17 is attached to the inner peripheral surface of the first cylindrical wall over the entire circumference. A second cylindrical wall 18 is provided integrally to the outer surface of the second frame 11 further to the outer peripheral side than the first cylindrical wall 16, and a band-shaped second felt member 19 is attached to the inner peripheral surface of the second cylindrical wall over the entire circumference. <P>COPYRIGHT: (C)2011,JPO&INPIT |
