To provide an electric braking device capable of suppressing deterioration of durability of a linear motion conversion mechanism.SOLUTION: An electric braking device 10 comprises a piston 80 that moves linearly together with a linear motion part 70 to press friction materials 24, 25 against a rotor 201, and a regulation part 90 that is provided between the piston 80 and the linear motion part 70 in a radial direction and regulates relative rotation between the linear motion part 70 and the piston 80. The regulation part 90 is configured to allow relative displacement of the piston 80 with respect to the linear motion part 70 in a first direction D1 and a second direction D2.SELECTED DRAWING: Figure 1

    【課題】直動変換機構の耐久性が低下することを抑制できる電動制動装置を提供する。【解決手段】電動制動装置10は、直動部70とともに直線運動することによって摩擦材24,25を回転体201に押し付けるピストン80と、径方向において、ピストン80と直動部70との間に設けられ、直動部70とピストン80との相対回転を規制する規制部90と、を備える。規制部90は、第1方向D1及び第2方向D2への直動部70に対するピストン80の相対変位を許容するように構成されている。【選択図】図1
