Claims

[Claims for Utility Model Registration] An input shaft, an output shaft having a gear train meshing with a gear train on the input shaft, and a gear loosely fitted onto the input shaft or the output shaft and forming the gear train. , a clutch hub fixed to the shaft, a gear spline provided integrally with the gear, splined to the clutch hub, rotated integrally with the hub, and slid on the outer circumference of the clutch hub in the hub axial direction. and a hub sleeve that selectively meshes with the gear spline, the outer peripheral surface being tapered and supported rotatably relative to the loosely fitted gear and rotatably together with the clutch hub. an outer cone having a tapered inner circumferential surface facing the outer circumferential surface of the inner cone and rotating integrally with the hub by spline engagement with the sliding hub sleeve; a double cone disposed between an inner circumferential surface and an outer circumferential surface of the inner cone, and supported so as to be rotatable and movable in the axial direction of the gear together with the loosely fitted gear; By moving the outer cone in the hub axis direction, the outer cone is attached to the double cone,
and a synchronizer key for frictionally engaging the double cone with the inner cone, wherein the double cone is provided with a through hole facing the outer circumferential surface of the inner cone and the inner circumferential surface of the outer cone, and the outer cone includes: A synchronizing device for a gear type transmission, characterized in that a through hole is provided that can be aligned with the above-mentioned through hole.
