Kind Code:
B2
Abstract:
[Problem] To provide an electric booster device that is more compact and lightweight. [Solution] In this electric booster device 1, a housing 3 is provided with: a rear housing 23 comprising a vehicle mounting plate 27; a front housing 20 disposed between a master cylinder 15 and the rear housing 23; and coupling members 17 for coupling the master cylinder 15 and the rear housing 23, with the front housing 20 therebetween. When hydraulic pressure is generated in the master cylinder 15, the hydraulic reaction force from the master cylinder 15 is thus transmitted to a first rear housing part 23A via the coupling members 17, thereby making it possible to reduce the rigidity of the front housing 20. This makes it possible to make the electric booster device 1 more compact and lightweight.
