Title:
RESIN TORQUE ROD
Document Type and Number:
Japanese Patent JP2015036576
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To form a weld line while shifted from a central line.SOLUTION: In a resin torque rod having a main body portion configured by integrally forming a first ring portion and a second ring portion on both end portions of a rod portion, a lightening hole is formed near the first ring portion eccentrically to an upper side to be asymmetric to a central line C0. As a cross-sectional area of an upper side with respect to the lightening hole becomes narrower than a lower side, resin flow at the upper side of the lightening hole is slowed down in comparison with that at the lower side, so that the resin flowing on an upper portion 62A of a ring molding portion 62 flows over an outer end portion P2 at a low speed as shown by an arrow A, the resin flowing on a lower portion 62B flows at a high speed as shown by an arrow B, and the flows are joined between an upper end portion Q1 and the outer end portion P2 to form a weld line 70 there.
