<p>PURPOSE:To obtain a simply constructed tilt mechanism without a demounting jig by composing the mechanism of a lock bearing provided with a lock operating mechanism, a lock shaft penetrating through the lock bearing, which mechanism is rocked by the movement of the lock shaft. CONSTITUTION:A lock shaft 1 and a cap 2 are engaged with each other in a lock shaft engagement part 1-a and a cap engagement part 2-a owing to rotation. A cap hook part 2-b is engaged with two portions of lock bearing engagement part 5-b and 5-b'. A push lock part is composed of a compression spring 3, a lock shaft tilted part 1-c, a lock shaft engagement face 1-d, and etc. A box 8 and a friction shaft 6 are engaged with each other at a friction shaft engagement part 6-a and a box engagement part 8-a in the rotating direction of the lock shaft, while the friction shaft 6 is locked in the rotating direction of the lock shaft by the engagement of a friction shaft rotation locking part 6-b and a friction shaft rotation engagement part 7-b. Tilting function is obtained for both the direction since there exits symmetrical structure along the center of the box 8.</p> |
