Abstract

PURPOSE:To prevent the shock noise produced when opening and closing a member to be rotated and to reduce an operation power, by a method wherein a fastening member and the member to be rotated are supported by means of hinges, and a balancer, which employes a spring for either of or both of compression and tension, is adopted. CONSTITUTION:The balancer 10 is constituted such that an end part 12, which is supported at a fulcrum A by means of a pin, is secured at one end of an outer cylinder 11, a rod 15, whose end secured through a slider 14 at a given position being about a neutral point of a coil spring 13a and a coil spring 13b, is inserted through an opeinng of the other end, a cover plug 16 is secured at the other end of the outer cylinder, and a hole 15a, which is supported at a fulcrum B by means of a pin, is bored in the other end of the rod 15. Said balancer 10 is held by means of a pin between a fulcrum A of a bracket formed at a given position of a fixing member 1 and a fulcrum B formed at a member to be rotated, being positioned away by a horizontal distance d from a supporting point of a member 2 to be rotated.
