Tiltable steering mechanism

A tiltable steering mechanism having:

• a support portion for rotatably supporting a steering shaft on which a steering wheel is mounted;
• a fixed portion fixed to a vehicle body and supporting said support portion tiltably about a tilt axis;
• a pair of tilt fulcrum forming members defining the tilt axis;
• an engaging portion provided on one of said support portions and said fixed portion and positioned at the intermediate portion between the two tilt fulcrum forming members;
• a restraining member mounted on the other of said support portion and said fixed portion for movement between an engaged position and a disengaged position and engageable with said engaging portion at said engaged position to fix said support portion to said fixed portion at a selected tilt angle and disengageable from said engaging portion at a selected tilt angle and disengageable from said engaging portion at said disengaged position to render said support portion tiltable relative to said fixed portion;
• holding means provided so as to be capable of assuming a holding position and a non-holding position and capable of holding said restraining member when said holding means assumes said holding position and causing said restraining member to assume said disengaged position when said holding means assumes said non-holding position;
• and
• an operating member for causing said holding means to selectively assume said holding position and said non-holding position;
• wherein said holding means has a pair of pivotable support hangers and shaft means extended between the free ends of said support hangers, said shaft means being adapted to bear against said restraining member in said holding position to thereby hold the same in said engaged position and to be disengaged from said restraining member in said non-holding position.
