ABSTRACT:
A valve timing controller includes a guide rotation member provided with a guide groove, a bearing rotation member radially supporting the guide rotation member, and a plurality of movable bodies sliding in the guide groove in accordance with a rotation of the guide rotation member. A plurality of link mechanisms connects the bearing rotation member with each one of movable bodies respectively, and rotates the bearing rotation member in accordance with a movement of the movable bodies. The valve timing of at least one of the intake valve and the exhaust valve is adjusted in accordance with a rotation of the bearing rotation body. A clearance gap is provided between the guide rotation member and the bearing rotation member in order to permit a relative radial movement of the guide rotation member with respect to the bearing rotation member.
