Embodiment Construction

[0037] Embodiments of the present invention will be described below based on the drawings. In addition, in the description, left and right mean left and right based on the drawing, and up and down mean up and down based on the drawing.

[0038]

[0039] refer to figure 1 . The rotation detection device 10 is installed, for example, near the axle of the front wheel of a two-wheeled vehicle. The vehicle speed of the two-wheeled vehicle can be measured from the rotation speed of the front wheels detected by the rotation detection device 10 . The upper part in the center of the drawing is attached to the vehicle body, and the part on the right side of the drawing is connected to the external connector. The part on the left side of the drawing faces the axle.

[0040] refer to figure 2 . The rotation detection device 10 is formed by attaching a magnetic detection element 11 for detecting a magnetic change, a magnet 12 for applying a magnetic field to the magnetic detection...

Abstract

A rotation detection device (10) has: a magnetism detection element (11) for detecting a change in magnetism caused by the rotation of a rotating body; a magnet (12) for applying a magnetic field to the magnetism detection element (11); a lead terminal (13) connected to the magnetism detection element (11); and a housing (30) in which the magnetism detection element (11), the magnet (12), and thelead terminal (13) are accommodated. The magnetism detection element (11), the magnet (12), and the lead terminal (13) are mounted to an inner case (20). The housing (30) comprises a first housing (40) and a second housing (50) which is fitted in the first housing (40) and which is disposed facing the rotating body. Either the first housing (40) or the second housing (50) is provided with an innercase fitting section (43) to which the inner case (20) is fitted.

Description

technical field [0001] The invention relates to an improved rotation detection device. Background technique [0002] For example, a rotation detection device is provided near the axle of the front wheel of a two-wheeled vehicle. The vehicle speed of the two-wheeled vehicle can be measured from the rotation speed of the front wheels detected by the rotation detection device. As a prior art related to such a rotation detection device, there is a technology disclosed in Patent Document 1. As shown in FIG. [0003] In the rotation detection device disclosed in Patent Document 1, a magnetic detection element and a magnet are arranged at the bottom of a bottomed cylindrical case, and resin is filled into the case to embed the magnetic detection element and magnet in the case. [0004] Components such as the magnetic detection element are fixed in the housing by the filled resin. It is possible to suppress displacement of components such as magnetic detection elements in the hou...
