PURPOSE: To surely limit the relative tiltable range of two members connected to each other by a knuckle joint by projecting a projection which is projected on either of first or second member, and freely abutted on the other member on a stop part. CONSTITUTION: When a second bar 3 is tilted, a tip of a projection 20 is abutted on a first bar 2 to stop a tilt of the second bar 3. The turn of the second bar 3 around the axis YY' is limited by the arc-shaped projection 20 in this position. The relative tiltable range of both bars 2, 3 can surely be limited by simple constitution where only the projection 20 is provided on either member. |
