Abstract

[Object]
To heighten the rigidity of a torque rod at the time of compression.
[Means for Solving the Object]
A rod section 12, a second ring section 16 and a main body portion 18 are integrally formed of resin. The rod section 12 is provided with a pair of intermediate ribs 44 which extends in parallel in the direction of a center axis CO. A center groove 45 is formed between the intermediate ribs 44. Front end portions 44 a of the intermediate ribs 44 located on a first ring section 14 side spread apart in the direction away from each other. A connecting rib 46 provided in a front end portion 45 a of the center groove 45 provides a connection between the front end portions 44 a. With this construction, even if a compression load is imposed on the front end portions 44 a in the direction to forcibly spread these end portions apart, this is suppressed by the connecting rib 46. The connecting rib 46 is arranged in the vicinity of the first ring section 14 whereby effective reinforcement can be achieved.

First claim

What is claimed is:

1 . A resin torque rod comprising:
a rod section; ring sections integrally formed in both ends in a longitudinal direction of the rod section; and a pair of lateral ribs ( 44 ) provided in the rod section ( 12 ) and extending in the direction of a center axis (C 0 ) in a parallel relationship; wherein respective one ends in the longitudinal direction of the lateral ribs are located in the vicinity of the ring section, and a connecting rib which provides a connection between respective one end portions in the longitudinal direction of the pair of lateral ribs is integrally provided in the rod section.

2 . The resin torque rod according to claim 1 , wherein the one end portions in the longitudinal direction of the pair of lateral ribs spread apart in the direction away from each other, and the connecting rib provides a connection between these spreading one end portions.

3 . The resin torque rod according to claim 2 , wherein a center groove is formed in the shape of a groove between the pair of lateral ribs, and the connecting rib is formed in an end portion in the longitudinal direction of the center groove.

4 . The resin torque rod according to claim 3 , wherein a projecting height of the connecting rib is smaller than those of the one end portions in the longitudinal direction of the lateral ribs.

5 . The resin torque rod according to claim 4 , wherein the connecting rib is located on the center axis (C 0 ).
