なかつた。BACKGROUND ART Conventionally, a safety valve for a sealed lead-acid battery of this type has a structure as shown in FIG. In FIG. 3, 1 is a cap-shaped safety valve, 2 is a valve barrel, 3 is a safety valve fixing plate, and 4 is an electrical cover. Installation of this type of safety valve and installation/fixation of the safety valve fixing plate are as follows:
The procedure was as shown in Figure 4. That is,
First, after injecting electrolyte through the nozzle 6 into the electrolyte A, insert the cap-shaped safety valve 1 shown as B into the valve cylinder 2, and then attach the safety valve fixing plate 3 shown as C to the safety valve 1.
By covering the safety valve over the top and fixing it to the cover 4 by heat welding or ultrasonic welding, a construction method was adopted that would prevent the safety valve from scattering even if the internal pressure of the cover 4 rose during charging. As a result of a literature search regarding this, the inventors were unable to find anything suitable.

まう。Problems to be Solved by the Invention However, in such conventional manufacturing methods, gas is generated inside the battery when the electrolyte is injected.
Before fixing the safety valve with a safety valve fixing plate, there was a problem that the safety valve would be pushed up due to the increase in internal pressure and be displaced or detached from the valve cylinder. If the safety valve shifts or comes off the valve cylinder, the airtightness inside the battery will not be maintained, and oxygen from the atmosphere will enter the battery and react with the negative electrode plate, causing self-discharge to proceed and significantly reducing the battery characteristics. This results in a defective product.

During the manufacturing process, the safety valve may become misaligned with the valve barrel.
The purpose is to prevent it from coming off.

である。Means for Solving the Problem In order to solve this problem, the present invention provides a safety valve fixing plate having a hole in the center that is smaller than the diameter of the safety valve, and a safety valve that is attached to the safety valve through the hole by vacuum suction or adhesive. This is a manufacturing method in which the safety valve is held in close contact with a substance or the like, and at the same time as the safety valve is attached to the valve cylinder, the safety valve fixing plate is fixed to the electrical cover from above the safety valve.

ができるものである。Function: According to this manufacturing method, the safety valve and the safety valve fixing plate are simultaneously supplied to the electrical cover, and the safety valve is attached to the valve barrel and fixed by the safety valve fixing plate at the same time, so that the safety valve can be fixed like the conventional one. This prevents the safety valve from being pushed up by an increase in internal pressure and shifting or coming off the valve cylinder before it is fixed by the safety valve fixing plate, thereby reducing product defects.

Incidentally, the same parts as in the conventional example are given the same reference numerals, and the explanation thereof will be omitted. FIG. 1 shows the structure of the safety valve of the present invention, and 5 is a through hole provided in the center of the safety valve fixing plate, the diameter of which is much smaller than the diameter of the cap. Figures 2A and 2B are schematic diagrams of the manufacturing process of the present invention. In the manufacturing process of the present invention, the electrolyte injection process using the nozzle 6 is the same as the conventional one, but the method of supplying the safety valve 1 and the safety valve fixing plate 3, indicated by B, is significantly different. That is, a hole for vacuum suction is provided in the center of the tip of the ultrasonic horn 7, and the safety valve 1 is sucked and held through the hollow hole 5 of the safety valve fixing plate 3, and at the same time the safety valve is interposed between the ultrasonic horn and the safety valve. It can also hold a fixed plate.
