閉部材を全開位置に停止させる。(b) Prior Art Generally, in a device in which a main member is rotatably provided with one end of an opening/closing member as a fulcrum, a shock absorbing device called a balancer is provided between the main member and the opening/closing member. The balancer biases the opening/closing member in the opening direction by its elastic force, reduces the force necessary for the opening/closing member to move in the opening direction, and stops the opening/closing member at the fully open position.

内部から当接する。As shown in FIG. 2, such a balancer includes a cylinder 21 that is open at one end and has a mounting section 24 at the other end, and is fitted into the cylinder 21 from the open end, and has a mounting section at the open end. A spring 25 is provided between the mounting portion 23 and the mounting portion 24 on the outer surface of the cylinder 21. Further, a stopper 26 is fixed to the shaft 22, and this stopper 26 contacts the open end 21a of the cylinder 21 from inside the cylinder 21.

化およびコストアンプを生じる欠点があった。(C1 Problem to be Solved by the Invention As shown in FIG. 3, when the opening/closing member 32 is opened in the direction of the arrow around the fulcrum 34, the balancer 31 stretches. 31 becomes longer as it moves away from the fulcrum 34 in the direction of arrow B. Here, the amount of expansion of the conventional balancer is the distance between the mounting portion 23 and the mounting portion 24 when contracted, as shown in FIG. 11 and the distance 12 between the open end 21 and the stopper 26. The distance 21 between the mounting portions 23 and 24 is determined by the space provided inside the device, and the distance 21 is equal to the sum of the distance 12 between the opening end 21 and the stopper 26. In this case, the distance M11 cannot be set very large.Therefore, the balancer 31 is installed as close to the fulcrum 34 as possible.However, the elastic force required for the balancer 31 increases as it approaches the fulcrum 34. The spring 25 has a large diameter, which has the drawback of increasing the size of the balancer and increasing costs.

スプリング５は円筒形コイルスプリングである。The cylinder 1 is formed of a hollow pipe, and one end thereof is an open end 1a. The inner diameter of the opening end 1a is reduced by drawing. A mounting portion 4 is formed at a substantially intermediate position in the longitudinal direction of the outer surface of the cylinder 1 . Inside the cylinder 1, a shaft 2 extends from the open end 1a with an arrow C
It is inserted in the direction. A mounting portion 3 is formed at the rear end of the shaft 2 in the direction of arrow C. cylinder l
A stopper 6 is fixed to a part of the shaft 2 inside. The outer diameter of this stopper 6 is made approximately equal to the inner diameter of the cylinder 1. A spring 5 is provided on the outer side of the cylinder 1 between a mounting portion 4 provided on the cylinder 1 and a mounting portion 3 provided on the shaft 2. This spring 5 is a cylindrical coil spring.

ストッパ６と開口端１ａとの当接によって規定される。When the attachment parts 3 and 4 are fixed to the opening member and the main member, respectively, the shock absorber 10 is completely retracted as shown in FIG. 1 with the opening member closed. In this state, the elastic force of the spring 5 is acting on the mounting portions 3 and 4 in the directions of arrows C and C, respectively. When opening the opening/closing member, the elastic force of the spring 5 acts in the opening direction, thereby reducing the force required for the opening/closing operation. The shaft 2 is movable in the direction of the arrow from the state shown in FIG. 1, and the range of movement in the direction of the arrow is defined by the contact between the stopper 6 and the open end 1a.

ダウンを実現できる。That is, the distance L2 between the stopper 6 and the open end 11a in the contracted state shown in FIG. 1 is the distance over which the shaft 2 can move in the direction of the arrow. Since the stopper 6 is located outside between the mounting members 3 and 4, this distance ITfIL2 is longer than the distance L1 between the two mounting members 3.4 (&0 Effects of the Invention This invention According to the method, the distance between the open end of the cylinder and the stopper can be made longer than the distance between the mounting part of the cylinder and the mounting part of the shaft, and the distance of the shaft can be made longer than the distance between the mounting parts. It can be roasted for a long time. Therefore, the mounting position can be moved away from the opposite point of the opening member, and when installed between the same main member and opening/closing member, the required elastic force can be reduced, and the size of the spring can be reduced. Since it can be made small, miniaturization and cost reduction can be realized.
