Document Type and Number:
Japanese Patent JP7168232
Kind Code:
B2
Abstract:
[Problem] To provide an electric valve which can reliably detect the magnetism of a magnet rotor with a magnetic sensor mounted on a substrate. [Solution] This electric valve (1) has magnetic transmission members (36a), (36b) disposed between a can (30) and magnetic sensors (35a), (35b) mounted on a substrate (85). On the outer peripheral surface (41a) of a magnet rotor (41) disposed on the inner side of the can (30), a plurality of N poles and a plurality of S poles extending in the rotational axis direction of the magnet rotor (41) are provided so as to be arranged side-by-side in the circumferential direction. Can-side ends (36a1), (36b1) of the magnetic transmission members (36a), (36b) are disposed so as to radially face the magnet rotor (41) through the can (30).
