It is formed slightly smaller than the diameter of the cross-sectional circle.
前記レバー保持手段(47)は、その一端が座受部材(7)の内底面における、前記係合ピン(42)よりもレバー(35)の取手部(40)寄りの位置に固定されている。 One end of the lever holding means (47) is fixed to a position closer to the handle (40) of the lever (35) than the engagement pin (42) on the inner bottom surface of the seat receiving member (7). .
レバー(35)を持ち上げた状態に保持させるには、レバー(35)を、取手部(40)を握持して持ち上げて上方に移動させ、前記レバー保持手段(47)の開口部(48)を押し広げながら、レバー保持手段(47)のひ字状内に嵌入させると、レバー保持手段(47)は、レバー(35)の長杆部(37)を挾持した状態となり、レバー(35)がその位置に保持される。 In order to hold the lever (35) in the lifted state, the lever (35) is lifted by gripping the handle (40) and moved upward to open the opening (48) of the lever holding means (47). When the lever holding means (47) is inserted into the shape of the lever while spreading the lever, the lever holding means (47) is in a state of holding the long flange portion (37) of the lever (35), and the lever (35) Is held in that position.
