Claims

[Scope of Claim for Utility Model Registration] (1) A rotary transmission shaft 1 that protrudes from the bearing port to the outside of the housing 21 and has a stepped rotary body attached to its tip, and a rotary transmission shaft 1 that projects inside the housing against spring pressure. A feed rotary plate 7 that is loosely fitted and has a locking step with a partially gently inclined cam surface 11 formed at a predetermined position of each continuous fan-shaped radial shape 9, 9', which has the same center angle around the transmission shaft. and a locking portion that is fixed to the transmission shaft within the housing and is removable from the locking step in the same direction of movement at a corresponding position in each fan-shaped radial area corresponding to the fan-shaped radial shape, and is operated by a feed rotary plate. an intermediate rotary plate 12 to be driven; a driven rotor 17 which is in pressure contact with a bearing port outside the housing and is pivotally supported so as to be movable along the transmission shaft against spring pressure; Each arc-shaped opposing area 24 is divided by the central angle of the fan-shaped radial shape on both annular surfaces where the driven rotor and the casing outside the bearing port are in contact with each other.
, 27 have intermeshed cam surfaces 25, 26; 28 which are uneven at an angle steeper than the inclination angle of the cam surface.
, 29 are formed. (2) The means for pushing the feed rotary plate from the vertical direction about the shaft is a protrusion 35 protruding from the side opposite to the cam surface of the feed rotary plate, and a means for pushing the protrusion by reciprocating in the direction perpendicular to the shaft. A push button 3 having a push piece 31 that slides into contact with the protrusion and pushes the protrusion so as to be able to return and rotate a predetermined angle around the push button 3.
0. A unidirectional step-by-step rotation device according to claim 1 of the utility model registration claim. (3) The angle at which the pushing piece of the push button slides and pushes the protruding piece to rotate is at least an angle that exceeds the central angle occupied by the steeply inclined convex cam surface of the bearing port. The unidirectional stepwise rotation device according to scope 2.
