ロツクを開発提案したのである。 Therefore, the applicant previously supported the chain presser on the side plate so as to be able to swing freely, and
The chain holder is provided with a spring that biases the chain holder toward the neutral position, and the side plate is provided with a holder having a holding piece that supports the spring in the neutral position, so that the chain holder can be moved to the neutral position by the chain. When the chain holder deviates from the neutral position due to deviation from the chain holder, that is, foreign matter or the like gets into the chain holder, the limit switch of the motor that drives the chain is activated,
He developed and proposed an electric chain block to stop the motor.
