Abstract

The present invention relates to a torque sensor cover. According to an embodiment of the present invention, as a second cover is formed of plastic through injection-molding, costs and weight can be reduced as compared with a wire cover manufactured of aluminum through casting according to the related art.

First claim

What is claimed is:

1. A torque sensor cover comprising:
a first cover surrounding a steering shaft to which a torque sensor is coupled and having a through-hole through which an electric wire connected to the torque sensor passes at one side thereof;
a support member coupled to and supported by an inner peripheral surface of the through-hole of the first cover and having a hole through which the electric wire passes; and
a second cover detachably coupled to the first cover, axially pressing and supporting the support member,
wherein a guide protrusion protruding outwards is formed at a periphery of the through-hole of the first cover,
wherein the second cover comprises an inner body inserted into the guide protrusion, for axially pressing the support member, and an outer body spaced outwards from the inner body and surrounding an outer peripheral surface of the guide protrusion,
wherein a coupling boss is formed on an outer peripheral surface of the guide protrusion, and
wherein a coupling hole into which the coupling boss is inserted to be coupled to the coupling hole is further formed in the outer body.

2. The torque sensor cover of claim 1 , wherein a step is formed in the through-hole of the first cover to protrude inwards such that the step supports one side surface of the support member.

3. The torque sensor cover of claim 1 , wherein an inclined tapered surface is formed in the coupling boss such that an outwardly protruding height of the inclined tapered surface decreases as it goes toward the second cover.

4. The torque sensor cover of claim 1 , wherein a seal member is provided on a lower surface of the first cover.

5. The torque sensor cover of claim 1 , wherein the second cover is formed of plastic through injection-molding.

6. The torque sensor cover of claim 1 , wherein a seal member is provided on a lower part of the first cover.
