## Abstract

Provided is a torque rod which has a first annular part of resin adapted to connect to a power unit; a second annular part of resin adapted to connect to a vehicle body; a connecting portion of resin that connects the first and second annular parts while arranging these parts at mutually twisted positions, the connecting portion having, at a surface including an outer cylindrical surface of the first annular part, a recess; a first elastic member provided in an inner cylindrical surface of the first annular part; a first metal collar member of which outer peripheral portion is supported by the first elastic member; a second elastic member provided in an inner cylindrical surface of the second annular part; a second metal collar member of which outer peripheral portion is supported by the second elastic member; a first rib structure formed on the surface including the outer cylindrical surface of the first annular part, the first rib structure having an end portion placed in the recess of the connecting portion; and a second rib structure formed on a surface including an outer cylindrical surface of the second annular part, the second rib structure having an end portion between the first and second annular parts at a position nearer to the first annular part than the end portion of the first rib structure.

## Claims

### Claim at position 1

-7. (canceled)

### Claim 8

A torque rod comprising:
a first annular part of resin adapted to connect to a power unit;
a second annular part of resin adapted to connect to a vehicle body;
a connecting portion of resin that connects the first and second annular parts while arranging these parts at mutually twisted positions, the connecting portion having, at a surface including an outer cylindrical surface of the first annular part, a recess;
a first elastic member provided in an inner cylindrical surface of the first annular part;
a first metal collar member of which outer peripheral portion is supported by the first elastic member;
a second elastic member provided in an inner cylindrical surface of the second annular part;
a second metal collar member of which outer peripheral portion is supported by the second elastic member;
a first rib structure formed on the surface including the outer cylindrical surface of the first annular part, the first rib structure extending toward the second annular part so that an end portion thereof is placed in the recess of the connecting portion; and
a second rib structure formed on a surface including an outer cylindrical surface of the second annular part, the second rib structure having an end portion between the first and second annular parts at a position nearer to the first annular part than the end portion of the first rib structure.

### Claim 9 (depends on 8)

A torque rod as claimed in claim 8, in which the first rib structure and the second rib structure are overlapped in a longitudinal direction of the torque rod.

### Claim 10 (depends on 8)

A torque rod as claimed in claim 8, in which the second rib structure is constructed to have a plurality of parallel ribs that extend on the surface including the outer cylindrical surface of the second annular part.

### Claim 11 (depends on 8)

A torque rod as claimed in claim 8, in which the first rib structure extends to an end of the recess, the end being placed near the second annular part.

### Claim 12 (depends on 8)

A torque rod as claimed in claim 8, in which the first rib structure is a rib structure that is formed on the outer cylindrical surface of the first annular part and constitutes a crest part at a middle position of the first annular part in the direction of thickness.

### Claim 13 (depends on 8)

A torque rod as claimed in claim 8, in which the second metal collar member comprises flange parts that constitute end surfaces and a body part that is sandwiched between the flange parts.

### Claim 14 (depends on 8)

A torque rod as claimed in claim 8, in which the second elastic member comprises a first hollow part that is provided at a side of the second metal collar member that is directed toward the first annular part and a second hollow part that is spaced from the first hollow part and placed nearer to the first annular part than the first hollow part.
