Kind Code:
B2
Abstract:
To achieve downsizing of a liquid pressure motor with a speed reducer.SOLUTION: A liquid pressure motor 100 with a speed reducer includes: a motor housing 11 which houses a motor part 20; a gear housing 32 having a housing recessed part 33 which opens on an end surface 32a and houses a speed reducing part 35, the gear housing 32 connected to the motor housing 11 in a state that the end surface 32a is butted with an end surface 12a of the motor housing 11; and an O ring 50 which seals a gap between the end surface 12a of the motor housing 11 and the end surface 32a of the gear housing 32. The speed reducing part 35 has a first planetary gear mechanism 40 which reduces a speed of rotation of a motor shaft 21 and outputs the rotation. A first ring gear 42 of the first planetary gear mechanism 40 has a protruding part 42a protruding from the end surface 32a of the gear housing 32 to the motor housing 11. The O ring 50 is supported at its inner periphery by the protruding part 42a of the first ring gear 42.SELECTED DRAWING: Figure 2
