BUFFER DEVICE FOR SMALL-SIZED ROLLER SHADE
A buffer device (5) for small-sized roller shade comprises a housing body (51), a covered cylinder (52) coveredly provided within one end of the housing body (51), an oil seal (53) coveringly provided over the outer edge of the covered cylinder (52) and sealing with respect to the interior of the housing body (51), a covering body (54) coveringly secured onto and then integrated with the top edge at one end of the housing body (51), a spring (55) surrounding the outer edge of the covered cylinder (52) far away from the housing body (51) together with the covering body (54), a rotating body (56) being provided for accommodating and coveringly positioning the covered cylinder (52) around which the spring (55) is provided, such that the spring (55) and the covered cylinder (52) are embeddedly combined together to be rotated, a closure cap (57) being coveringly connected over the outer edge of the covered cylinder (52) and synchronously rotated therewith, and a securing part (58) being directed away from one end of the housing body (51) while combined with and fixed to the closure cap (57) and the covered cylinder (52). Thus, the buffer device (5) is reduced in volume to be applicable to a roller shade used on a door/window and a small-sized roller shade used within a car door of limited thickness, for providing a shade panel (7) with buffer effect in the drawing or furling process.
