Title:
ROTATIONAL SPEED DETECTION DEVICE AND VEHICLE SPEED DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/008257
Kind Code:
A1
Abstract:
Provided is a rotational speed detection device and a vehicle speed detection system which can be easily mounted to a two-wheeled vehicle.
A rotational speed detection device (40a) is provided with: a connection shaft (402) connected to a shaft (340) adapted for connection with the connection shaft (402), the shaft (340) being formed integrally with a driven gear meshing with a gear which rotates as a wheel shaft of the two-wheeled vehicle rotates; and a magnetism detection means (409) for emitting a rotation signal to an instrument as the connection shaft (402) rotates. The shaft (340) is rotatably supported by an extension section (300) of a hub (30), and the connection terminal (405) of the rotational speed detection device (40a) is fitted in a connection hole (302) formed in the extension section (300).
