Small hydraulic excavator
To provide a small hydraulic excavator, which even may have an upperstructure formed such that at least its rear end swings within a body width range and having a limited installation space for devices, that allows an accumulator to be disposed and allows the accumulator to be protected from external force generated during work. The present invention relates to a rear small-swing type mini excavator that includes an accumulator 30 accommodating and recovering potential energy and hydraulic energy used by at least one of drives of an undercarriage 1, an upperstructure 2 formed such that its rear end swings within the body width range of the undercarriage 1, and a working device 3. In the rear small-swing type mini excavator, the accumulator 30 is disposed between a valve block 26 and a front longitudinal board 41 of a longitudinal board member included in a main frame 10 along the front longitudinal board 41, and a pipe connected to the accumulator 30 and the valve block 26 is disposed closer to the accumulator 30 and the valve block 26.
