Claims

[Scope of Claim for Utility Model Registration] (1) A drive belt for a continuously variable transmission comprising an endless carrier and a V block that is continuously movable in the carrier in the circumferential direction, A drive belt for a continuously variable transmission, characterized in that a protection member is attached to one of the V-blocks at at least one location on the circumference to cover a part of the carrier from the belt outer circumferential side. (2) The protective member is located at four locations on the entire circumference of the belt.
The drive belt for a continuously variable transmission according to claim 1, which is attached to one of eight V-blocks. (3) The protection member includes one to three V blocks.
2. A drive belt for a continuously variable transmission according to claim 1 or 2, characterized in that the drive belt has a circumferential length of 1.5 cm. (4) The drive belt for a continuously variable transmission according to any one of claims 1 to 3, wherein the protection member is made of a ceramic material. (5) The protection member is installed with a gap provided between the protection member and at least one of the carrier and the V-block to allow relative movement of the carrier in the belt width direction with respect to the V-block. A drive belt for a continuously variable transmission according to any one of claims 1 to 4 of the utility model registration claims. (6) If the type of the drive belt is carrier 1.
