Claims (1)

[Scope of utility model registration request] By rotating the operating lever in one direction, it is possible to adjust the inclination angle of the tilting body, which is tiltably assembled to the support body, with respect to the support body, and to move the tilting body to its maximum tilt position. In the tilt angle adjustment device, the lock pin is biased by a spring toward a lock pin integrally provided on the support body or the first bracket connected to the tilting body, and the lock pin is fixed at the maximum tilt position of the tilting body. a lock plate capable of engaging with and fixing the tilting body at its maximum tilt position is attached to a second bracket connected to the tilting body or the supporting body coaxially and rotatably relative to the operating lever; The lock plate is engaged with the lock plate in the lock position to prevent the lock plate from engaging with the lock pin, and is disengaged from the lock plate in the unlock position to allow the lock plate to engage with the lock pin. A tilt angle adjusting device characterized in that a lock stopper is swingably assembled to the first bracket, and the lock stopper is connected to a lock lever assembled to the operating lever via an operating cable.
