Abstract
A frame connection member, which is fixedly mounted on one of an upper split frame and a lower split frame, is pivoted on the other split frame so as to revolve around a horizontal axis shaft line. An inversely tapered concavity for inserting a twisted shaft portion of a torsion bar from a direction meeting at right angles with the axis shaft line of the shaft portion is formed in the frame connection member. The frame connection member is provided with a first engagement member for engaging a biasing reaction force portion on one end side of the torsion bar, the other split frame being provided with a second engagement member for engaging a biasing reaction force portion on the other end side of the torsion bar. The other split frame has a revolution regulating member for regulating a revolving range of the frame connection member relative to the other split frame at a range larger than a predetermined open angle set by an angle regulating device. The torsion bar is simply and easily set by inserting the twisted shaft portion of the torsion bar into the inversely tapered concavity sideways and slightly twisting the twisted shaft portion.
