Title:
ROTATION DETECTOR
Document Type and Number:
Japanese Patent JP2016017939
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a rotation detector capable of preventing a reduction in the strength of a sensor attachment member.SOLUTION: A wheel velocity sensor 1 comprises: a sensor element 3 generating a pulse output signal on the basis of a rotating state of a sensor rotor; a signal cable 2 connected to the sensor element 3 and transmitting the pulse output signal; a sensor covering portion 4 integrally covering the sensor element 3 and the signal cable 2; and a sensor housing 5 formed of a synthetic resin material and holding part of each of the sensor covering portion 4 and the signal cable 2. The signal cable 2 includes a curved portion 2b bent within the sensor housing 5. At a time of molding the sensor housing 5, a pair of guide protrusions protrude perpendicularly to a planar surface including the curved portion 2b in opposite directions to each other within a cavity of molding dies. The paired guide portion protrude toward the curved portion 2b and prevent the movement of the curved portion 2b by a flow velocity of the resin material flowing into the cavity.SELECTED DRAWING: Figure 4
