In a locked position in which a front-end portion 2b of the latch ring 2 engaged with an engaging concave portion 3a of an operating lever 3 passes through a straight line connecting a cross-sectional center of the base-end portion 2a of the latch ring 2 and a cross-sectional center of an axle pin 9 and approaches a fixed seating plate 4, a threaded shaft portion 5b of a fastening bolt 5 is threadably engaged with a threaded hole 21 of the fixed seating plate 4 so that a head portion 5a of the fastening bolt 5 is brought into press-contact with a front surface of a front-end portion of the operating lever 3.
