The invention provides a centrifugal shoe clutch structure for a centrifugal shoe clutch, which prevents what is termed as clutch squeak from occurring due to vibrations of a clutch outer. The centrifugal shoe clutch structure including: a clutch inner configured to rotatably hold a plurality of clutch shoes respectively including friction members, and connected to an input rotary member; and a clutch outer connected to an output rotary member, provided surrounding an outer periphery of the clutch inner, configured to be connected to the clutch inner in accordance with rotation of the clutch shoes in an outer peripheral direction due to a centrifugal force, and thereby a rotary driving force of the clutch inner being transmitted to the clutch outer, wherein the clutch outer includes: a boss portion fitted to the output rotary member; a drum portion whose inner peripheral surface constitutes a cylinder-shaped friction surface configured to come into contact with the clutch shoes; and aconnecting wall portion connecting the boss portion and the drum portion together, and the boss portion, the drum portion and the connecting wall portion are integrally cast by use of the same cast iron material by casting.
Description
technical field [0001] The present invention relates to a structure of a centrifugal shoe clutch for preventing so-called clutch rattle caused by vibration of a clutch outer race among centrifugal shoe clutches. Background technique [0002] At present, in a dry type centrifugal brake shoe clutch, during the period from when the friction member lined on the centrifugal clutch brake shoe is in contact with the inner peripheral surface of the drum of the clutch outer race to when the friction member and the drum are completely engaged and connected In a state where the inner peripheral surface of the drum portion is in contact with and slides, the clutch outer ring may vibrate to cause sounding. Therefore, conventionally, in order to prevent clutch rattling when the clutch is connected, for example, as shown in Patent Document 1 below, an operation of welding an anti-vibration ring to the outer periphery of the clutch outer race has been performed. [0003] [Patent Document 1...
