いる。 Casters that are attached to the bottom of furniture, etc. and have a braking device are, for example,
This is disclosed in Japanese Patent No. 55-21845, which includes a braking member having one end pivoted on the turning main body, the other end being biased by a spring in the direction of the outer circumference of the wheel, and having a restraining piece. It is composed of an operating member having a cam portion for applying pressure against the force of a spring. When not braking, the cam pushes the braking member against the spring to separate the restraining piece from the locking groove of the wheel, and when braking, the force of the spring engages the restraining piece into the locking groove of the wheel. be. Therefore, the number of parts increases to three, and the braking member is moved only by the force of the spring, so if the rotation of the braking member becomes unsmooth due to deformation of the shaft attachment part, the cam will brake. There are problems in that even if the member is released, the restraining piece may not engage with the locking groove.
