Title:
ROTATION POSITION DETECTION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/103619
Kind Code:
A1
Abstract:
Provided is a device capable of accurately positioning a sensor in a prescribed position. A rotation position detection device for detecting a change in the magnetic flux of a rotor of a rotating electrical machine has a case 51. The case 51 has a container 52 for accommodating an electrical circuit component. A bottom wall 61 of the container 52 has radial ribs 74, 75, 76 extending radially on the top of the bottom wall 61. The case 51 has a plate-like reinforcement rib 53d extending between a cover 53 for accommodating a sensor and the bottom wall 61. A connection part 55 has two end part connection parts 84, 85 and intermediate connection parts 86, 87, 88 provided therebetween. The intermediate connection parts 86, 87, 88 keep an internal wall 62 and tightening part 54 in a prescribed positional relationship. The suppression of the deformation of the case 51 suppresses the positional displacement of the sensor.
