The wheel 21 is disposed at a non-contact position (braking release position). In this state, the wheel 21 is capable of rolling and turning.

  From this state, the handle 33 is rotated with respect to the holding member main body 31 in the clockwise direction (one direction side) in FIG. Thereby, the rotation member 322 rotates in the same direction, and the braking member 4 moves with the rotation of the rotation member 322.

  At that time, the turning shaft 2211 enters the guided hole 4111 of the guided portion 411 in the braking member 4 and the gap moving portion 4112 is passed through the gap between the first opposing wall 2211c and the second opposing wall 2222. As the turning member 322 rotates, the braking member 4 is guided by the braking member guide portion 5 and the pressing portion 42 of the braking member 4 moves in the direction approaching the wheel 21 (X1 direction in the figure).

  When the rotating member 322 further rotates, the pressing portion 42 of the pressing portion 42 of the braking member 4 comes into contact with the outer periphery of the wheel 21 as shown in FIG. At this time, the distance L2 from the pressing surface 42a to the surface of the gap moving portion 4112 of the guided portion 411 is formed to be larger than the distance L1 between the first opposing wall 2211c and the outer periphery of the wheel 21. By the rotation of the rotating member 322, the pressing portion 42 of the braking member 4 presses the outer periphery of the wheel 21 so as to expand the distance L1, and stops at the pressed position (braking position) (see FIGS. 1 and 2).

  Further, when the pressing portion 42 of the braking member 4 presses the outer periphery of the wheel 21, the gap moving portion 4112 of the braking member 4 is received by the first opposing wall 2211 c, and the pressing portion 42 of the braking member 4 becomes the outer periphery of the wheel 21. The wheel 21 can be braked so as not to roll and turn.

  When releasing the brake, the handle 33 is rotated with respect to the holding member main body 31 in the counterclockwise direction (the other direction) in FIG. Thereby, the rotating member 322 rotates in the same direction, and with the rotation of the rotating member 322, the braking member 4 is guided to the braking member guide portion 5, and the pressing portion 42 of the braking member 4 moves to the wheel 21. Move away (X2 direction in the figure).

  When the rotating member 322 further rotates, as shown in FIG. 5, the pressing portion 42 of the braking member 4 moves away from the outer periphery of the wheel 21 to a non-contact position (braking release position) where it does not contact the wheel 21. Moving. As a result, the brake is released.

  In the caster device 1 of the present invention configured as described above, the caster unit 2 includes a braking member guide unit that guides the braking member when the braking member moves in the range from the braking release position to the braking position. As in the prior art, it is not necessary to provide a braking member guide part separately from the caster part, the entire apparatus has a simple structure, and the assembling work can be performed in a short time.

  Further, since the first opposing wall is formed on the turning shaft and the second opposing wall is formed on the opposing portion of the wheel holding member, the braking member guide portion can be formed more easily.

  Further, since the pressing portion presses the outer periphery of the wheel, it is possible to easily brake the wheel so that the wheel cannot roll and turn, and the entire apparatus can be further simplified.

  The caster device 1 of the present invention configured as described above is used as, for example, the caster device 1 of the floor head base 100. Specifically, for example, as shown in FIG. 11, the floor head base body 101 is placed on the upper surface of the holding member 3 of the caster device 1, and the floor head base 100 is configured by the caster device 1 and the floor head base body 101. .

And the locking portion 6 is pressed.

  As a result, the locking portion 6 moves against the urging force of the urging member 62 and moves radially inward (Y1 direction) of the wheel body 210 as shown in FIG. However, the locking projection 210a of the wheel body 210 enters. Thereby, the latching | locking part 6 and the wheel main body 210 latch, and the wheel main body 210 is braked so that rolling is impossible. Further, when the locking convex portion 210a of the wheel body 210 is pushed into the locking concave portion 61 of the locking portion 6, the back portion 61a of the locking concave portion 61 is stopped against the tip 210b of the locking convex portion 210a. As a result, the wheel body 210 is braked through the locking portion 6 so as not to turn.

  On the other hand, when the handle 33 is operated in the counterclockwise direction (the other direction), the braking member 4 is guided by the braking member guide portion 5 and the pressing portion 42 of the braking member 4 moves away from the wheel body 210 (X2). Direction) to stop the pressing of the locking portion 6. Accordingly, the locking portion 6 is moved radially outward (Y2 direction) of the wheel main body 210 by the urging force of the urging member 62, and the locking convex portion of the wheel main body 210 is moved from the locking concave portion 61 of the locking portion 6. 210a comes off, and the locking portion 6 and the wheel body 210 are unlocked. Therefore, in this state, the wheel 21 (wheel main body 210) is in a state where it can roll and turn.

  In this embodiment, the wheel body 210 is provided with the locking projection 210a and the locking portion 6 is provided with the locking recess 61. However, for example, the wheel body 210 is provided with the locking recess, The part 6 may be provided with a locking projection, and can be changed as appropriate.
