Speed controller

A speed controller, comprising:

• a check valve that controls a flow direction of pressurized fluid in a fluid channel that connects a first port and a second port to each other;
• and
• a needle valve that controls flow rate of the pressurized fluid supplied to a fluid-pressure cylinder or discharged from the fluid-pressure cylinder, wherein
• a valve body of the speed controller includes a main body that extends along a first axis and a mounting portion to be mounted on a cylinder port of the fluid-pressure cylinder,
• the mounting portion projects from a side of the main body along a second axis that intersects the first axis orthogonally,
• the first port is formed in the main body and the needle valve and the check valve are disposed coaxially along the first axis,
• the second port is formed in the mounting portion, and
• a position at which the mounting body is connected to the side of the main body is away from the first axis in a direction of a third axis that orthogonally intersects the first axis and the second axis.
