Claims

[Scope of utility model registration request]

(1) A camshaft device including a timing pulley driven by a crankshaft, a camshaft driven in conjunction with the timing pulley, and a coupling mechanism that connects the timing pulley and the camshaft so that the timing can be adjusted. , the connecting mechanism has a first connecting member whose i end is connected to the timing pulley and is rotatably supported by the casing, and is coaxially spline-fitted to the first connecting member, and the axis of the first connecting member is adjusted by hydraulic pressure. a second connecting member that is moved in the direction and has a first helical gear formed on its outer periphery; a return spring that urges the second connecting member in a direction that resists the hydraulic pressure; and a second connecting member that is fixed to the camshaft. a second helical gear that meshes with the first helical gear of the member, and the movement of the second connecting member causes the first connecting member and the second helical gear to rotate relative to each other, so that the timing pulley A camshaft device that connects a camshaft and a camshaft in a timing-adjustable manner.

(2) the camshaft consists of an intake camshaft and an exhaust camshaft, and the first helical gear consists of two helical gears whose teeth are cut in opposite directions;
The camshaft device according to claim 1, wherein the second helical gear comprises two helical gears each meshing with the first helical gear.
