Title:
ROTATIONAL MOVEMENT RANGE RESTRICTING DEVICE FOR ROTARY SOLENOID
Document Type and Number:
WIPO Patent Application WO/2012/023159
Kind Code:
A1
Abstract:
A rotational movement range restricting device (1) for a rotary solenoid (M) includes a pair of restricting portions (4p, 4q) for restricting the rotational movement range (Zr) of an engagement portion (3) that rotates integrally with the shaft (2s) of a magnet rotor (2). In configuring the rotational movement range restricting device (1), the engagement portion (3) is provided with a movement restricting means (5) including a static inertia imparting mechanism (5a) for imparting a static inertia by a predetermined inertial force and a braking mechanism (5b) for braking by a predetermined braking force. When the engagement portion (3) rotates from one stop position (Xp or Xq) restricted by one restricting portion (4p or 4q) to the other stop position (Xq or Xp) restricted by the other restricting portion (4q or 4p), the engagement portion (3) moves from a temporal locking position (Xm) to the other stop position (Xq or Xp), the temporal locking position (Xm) being positioned a predetermined rotational interval (Ls) before the other stop position (Xq or Xp).
