DRIVE DEVICE
Document Type and Number:
Japanese Patent JP3111872
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent adhesion of grease applied on a worm gear on a friction engaging face of a gear mechanism by a simple configuration by providing a side plate section formed by bending a side of a plate spring between friction locking sections of a first gear and a second gear and the worm gear.
SOLUTION: Even if a worm gear 5 rotates and grease applied on the worm gear 5 is sputtered as shown by an arrow mark b, grease is blocked by a side plate section 16B of a plate spring 16 so that grease does not adhere on a friction locking face of a collar of a cylindrical body and bush and friction locking relationship between the cylindrical body and a sleeve is maintained. In such a mode, it is possible to use the plate spring 16 for preventing abnormal sound generated due to the travel of a rotary shaft of a motor in the axial direction and prevent the adhesion of grease applied on the worm gear 5 on a friction locking face of a gear mechanism provided with a friction locking mechanism.
