Claim 3:
4. The horological movement according to claim 1, wherein each second distant portion from said at least one second distant portion has, in a polar coordinate system (R, θ) perpendicular to said first axis of rotation and centered thereon, a second inclined surface (SI2) when the pallet assembly is in any one of the equilibrium angular positions βER (θ) corresponding to any one of the angular positions of a first range of angular positions, from said at least one range of angular positions, wherein said second distant portion is in contact with a first distant portion from said at least one first distant portion (PCP1, PCP2), the second inclined surface being configured in such a way that each first distant portion from said at least one first distant portion may slide on said second inclined surface while the escape wheel passes through a second range of angular positions, from said at least one range of angular positions, which is relative to the first and second distant portions considered and while the pallet assembly angularly follows a curve defined by the corresponding equilibrium angular positions βER (θ).
