Claims

[Claims for Utility Model Registration] (1) A driven shaft; a hob fixed to the end of the driven shaft; a rotary drive body located on the outer periphery of the driven shaft; facing the suction surface of the rotary drive body; a spring means that connects the armature and the hob and normally biases the armature away from the rotary drive body; An electromagnetic clutch device equipped with an electromagnetic body that is attracted to and integrated with the hob, wherein a pull-out jig for pulling out the hob from the driven shaft is hung on the outer circumference or inner circumference of the end of the hob. An electromagnetic clutch device characterized by forming an engagement recess facing in the radial direction of the hob. (2) In paragraph 1 of the claims for utility model registration,
The engaging recess is an electromagnetic clutch device consisting of an annular groove. (3) Scope of claims for utility model registration, paragraph 1 or 2
In paragraph 1, the extraction jig is an electromagnetic clutch device having a pair of extraction arms that can be opened and closed, and engagement claws that are formed at the tips of the extraction arms and that are removable from engagement recesses. (4) Scope of claims for utility model registration, paragraph 1 or 2
2. The electromagnetic clutch device according to item 1, wherein the engaging recess is formed of an annular groove, and the end face of the hob is formed with at least a pair of jig insertion grooves communicating with the bottom of the annular groove. (5) In paragraph 4 of claims for utility model registration,
The pull-out jig is an electromagnetic clutch device that includes a pair of pull-out arms that cannot be opened or closed and have engagement claws that can enter the annular groove from the jig insertion groove and rotate within the annular groove.
