Document Type and Number:
WIPO Patent Application WO/2010/071067
Kind Code:
A1
Abstract:
Provided is a position detection device which allows for smooth operation of a handle grip and allows for improvement in detection accuracy. The position detection device (1) includes: a magnetic member (4) which rotates according to a rotation operation of the handle grip (3); a magnetism detection unit (5) which detects the change in a magnetic flux density of the magnetic member (4); and a case (6) which contains the magnetic member (4) and the magnetism detection unit (5). The magnetic member (4) has: an engagement hole (41) to be engaged with the handle grip (3); a first shaft (43) arranged in the engagement hole (41) at the side of an operation unit (3c) of the handle grip (3); and a second shaft (44) arranged at the side opposite to the first shaft (43). The case (6) is formed by a first case and a second case (61, 62). The first case (61) has a first opening (63) which rotatably supports the first shaft (43). The second case (62) has a second opening (65) which rotatably supports the second shaft (44).
