Note that the same reference numerals in the figures indicate the same or corresponding parts. Figure 2

Claims

[Scope of utility model registration request]

(1) A movable core that is attracted when the fixed core is energized and allows the rotating body to be braked to rotate, and an effective dimension that is slightly larger than the set gap between the above-mentioned two cores on the end face of the movable core on the side opposite to the fixed core. a rack tooth portion in which a plurality of rack teeth having the same tooth height are carved; a pressing member that faces the rack tooth portion with a predetermined gap therebetween and is formed with an inclined surface having a predetermined angle with the opposing surface number;
- A plurality of rack teeth having the same specifications that engage with the rack teeth are formed on one end surface, and an inclined surface that abuts the inclined surface in a wedge shape is formed on the other end surface, and the fixed iron core is biased. Further, when the gap between the two iron cores becomes larger than the effective tooth height, an adjustment is made to move in a direction perpendicular to the axis of the rotary body to be braked and sequentially lock onto the lower rack tooth of the rack tooth portion. and an elastic body that brakes the braked rotary body via the movable core adjusting member and the pressing member when the fixed core is deenergized.
