PROBLEM TO BE SOLVED: To provide a trochoidal pump, configured so that pump efficiency can be improved.SOLUTION: A pump body 11 of the trochoidal pump 1 is constituted by a pump housing body 12 and a pump base 14, and a circular rotor housing portion 32 is formed in an opposed surface 31 of the pump housing body 12. A pump rotor 33 within the rotor housing portion 32 is constituted by a rotor inner 34 and a rotor outer 35, and the rotor inner 34 is received in an inner housing chamber 41 of the rotor outer 35. Strip-like grooves 91, 92 are provided on at least one of the outer periphery of the rotor outer 35 and the inner periphery of the pump housing body 12 to extend in the circumferential direction. |
