Title:
ディスクブレーキ
Document Type and Number:
Japanese Patent JP7220281
Kind Code:
B2
Abstract:
The present disk brake includes a braking force holding mechanism configured to restrict a rotation of a rotational shaft (a ratchet gear) to hold a braking force based on driving of a solenoid actuator. The braking force holding mechanism includes a holding member configured to move based on the driving of the solenoid actuator to restrict the rotation of the ratchet gear, and an engagement member coupled with this holding member. The engagement member is rotatably supported on a gear housing portion, and is configured to prohibit a movement of the holding member. Due to this configuration, an excitation force applied from outside to the holding member can be canceled out with the aid of the engagement member, and thus the disk brake can realize a size reduction and achieve cost saving.
