By combining this with a "crank-like mechanism," there is no need to provide a bracket to support the lever to prevent it from rotating, unlike conventional products, which reduces the number of assembled parts and is more economical. This eliminates the horizontal wobbling of the lever that often occurs with conventional products, making it extremely easy to operate.
又、レバーは若干の揺動運動をするに留まるた
