害にならない位置にしておくものである。Next, to explain the assembly operation of the main parts of the brake device of the present invention, the screw punch 13 protruding from the interlocking rod 12 and the spring pressing rod 14 are initially separated, and the other end of the spring pressing rod 14 is separated. When the nut 19 is screwed into the male screw provided in the screw hole and the nut 19 is tightened so that the spring pressing rod 14 moves toward the right stopper 17 against the spring 18, the screw punch 13 and the spring pressing rod 14 are tightened.
The distance between them gradually separates, and with a certain gap created, the tips of the screw punch 13 and the spring pressing rod 14 are brought together, and the nut 19 is loosened to move the spring pressing rod 14 toward the screw punch 13. Then, the spring pressing rod 14 is further moved, and when the tip reaches the end of the screw punch 13, one end of the spring pressing rod 14 and the other end of the screw punch 13 are screwed together to form a connected state. After this connection work is completed, the nut 19 is removed from the spring pressing rod 14 or left in a position where it does not prevent the spring pressing rod 14 from sliding.

える効果を有する。According to this invention, since the spring pressing rod 14 can be easily moved toward the right stopper 17 against the spring 18 when assembling the brake device, the screwing connection with the screw punch 13 can be easily performed. It is possible to solve the difficulty of assembling the conventional single-acting spring-equipped brake cylinder 6 to connect it to the brake actuating device A of the pivot shaft against the spring, and also to reduce the length of the connection between the screw punch and the spring pressing rod. By adjusting the above, it is possible to adjust the biasing force of the spring.
