PROBLEM TO BE SOLVED: To provide a balance mechanism that has a structure without using a balance weight, is decreased in weight, is reduced in the weight serving as a drive object, can be constituted at a low cost by using a motor of a low output, and can save a space.SOLUTION: This balance mechanism is provided with a balance member so as to match with the weight of an object 16 provided to move up and down with respect to the object 16. The balance mechanism has mechanism units 11, 12 and 13 for making a balance relationship, and the balance member is an elastic member 18 with a portion connected to the mechanism unit. In the balance mechanism, a portion uses a coupled elastic member, so that the weight of the whole equipment is reduced, the weight of a portion serving as a drive object is reduced, and thereby a drive motor of a low output can be used.
【課題】釣合錘を用いない構造とし、軽量化を図り、駆動対象となる重量を軽減し、低出力のモータを用いて安価に構成でき、省スペース化を実現できる釣合機構を提供する。【解決手段】この釣合機構は、昇降するように設けられた対象物16に対して当該対象物の重量と釣り合うように釣合部材を設けた釣合機構であり、釣合関係を作る機構部11,12,13を有し、釣合部材は機構部に一部が結合された伸縮部材18である。釣合機構では、一部が結合された伸縮部材を利用するため、機器全体を軽量化し、駆動対象となる部分の重量を軽減し、低出力の駆動モータを用いることが可能となる。【選択図】図1
