Document Type and Number:
Japanese Patent JP2023158486
Kind Code:
A
Abstract:
To reduce cost for assembling a holding shaft to a general-purpose component.SOLUTION: A holding shaft 30 mounted on a torque limiter 20 for applying a certain rotation load to a separation roller 4a when the mounted separation roller 4a rotates includes a rotation restriction part 40 which is inserted in and engaged with engagement parts 20c, 20d of the torque limiter 20 for restricting the rotation of the torque limiter 20. The rotation restriction part 40 includes: an outer peripheral part 43 which protrudes in the outer diameter direction from an outer periphery of the holding shaft 30, and in which the outer peripheral surface is formed in parallel with the outer peripheral surface of the holding shaft 30; and an engagement part 42 which is connected to the outer peripheral part 43 and is engaged with the engagement parts 20c, 20d of the torque limiter 20. The engagement part 42 has an R-shaped tip part 41 opposing the engagement parts 20c, 20d of the torque limiter 20, and the width in the direction orthogonal to the insertion direction of the engagement parts 20c, 20d of the torque limiter 20 is the width that can be inserted into the engagement parts 20c, 20d of the torque limiter 20.SELECTED DRAWING: Figure 2
