SLIDE ASSISTING DEVICE FOR SLIDING DOOR

摘要

PROBLEM TO BE SOLVED: To simplify a structure of a driving mechanism to reduce manufacturing cost while maintaining the compact form of the driving mechanism for facilitating the support into a casing.

SOLUTION: This slide assisting device for the sliding door is provided with the driving mechanism 4 for storing up the assisting force when the sliding door slides in one direction and exerting the assisting force when the sliding door slides in the other direction and the casing 1 supporting the driving mechanism 4 and provided in the inside of a rail R for guiding travel of a traveling member 2 of the sliding door. The driving mechanism 4 is composed of a spring 41 for storing up and exerting the assisting force and a fluid pressure damper 43 for suppressing the exertion of the assisting force of the spring 41. In this driving mechanism 4, the spring 41 and the fluid pressure damper 43 are separate parts and are arranged in the inside of the casing 1.
