Abstract:
A bevel gear mechanism used for transmitting power between two axes not parallel to each other, said bevel gear mechanism comprising:a first bevel gear of a ring shape having teeth projecting on one disk surface side; a second bevel gear of a ring shape arranged to be concentric with said first bevel gear and having teeth placed on a concentric circle basis on the same surface side as the teeth of said first bevel gear; a support member for substantially restraining rotation of the second bevel gear relative to said first bevel gear and for elastically supporting the second bevel gear relative to said first bevel gear so that in a free state the teeth of said second bevel gear can project relative to the teeth of said first bevel gear in a direction of a rotation axis and so that in a pushed state, when the teeth of said second bevel gear is pushed to the first bevel gear side in the direction of the rotation axis, the teeth of said second bevel gear can be retracted to the first bevel gear side; and a fluctuation suppressing member extending between the second bevel gear and the first bevel gear for suppressing fluctuation of said second bevel gear relative to said first bevel gear along a predetermined diameter direction.
