Abstract
In a lacing module, one gear of a worm wheel gear and a clutch gear includes a protrusion, and another gear of the worm wheel gear and the clutch gear includes a recess. The worm wheel gear meshes with a worm gear rotatable together with a shaft of a motor. The clutch gear is fixed to a spool shaft portion of a spool around which a string can be wound. The protrusion protrudes in a direction between the one gear and the another gear. The recess is recessed in the direction between the one gear toward and the another gear. At least an end of the protrusion protruding from one gear to the other gear in a vertical direction is fitted into the recess.

A lacing module comprising:
- a spool that includes a barrel portion around which a string is able to be wound, and a spool shaft portion extending along a first axis extending in a vertical direction;
- a worm gear that is rotatable together with a shaft of a motor;
- a worm wheel gear that meshes with the worm gear;
- and
- a clutch gear that is fixed to a radial outer end of the spool shaft portion, and is above the worm wheel gear;
- wherein
- the spool shaft portion is rotatable about the first axis together with the barrel portion and the clutch gear;
- the worm wheel gear includes a first gear through-hole extending along the first axis;
- the spool shaft portion is inserted into the first gear through-hole;
- one gear of the worm wheel gear and the clutch gear includes a protrusion, and the other gear includes a recess;
- the protrusion is on a surface of the one gear opposing another gear of the worm wheel gear and the clutch gear, and protrudes from the one gear to the another gear in the vertical direction;
- the recess is on a surface of the another gear opposing the one gear, and is recessed from the one gear to the another gear in the vertical direction;
- and
- at least an end of the protrusion protruding from the one gear to the another gear in the vertical direction is fitted into the recess.
