A brake fluid pressure control device for a saddle-type vehicle, comprising: a base body to which a flow path for a brake fluid is formed; a coil which is erected on the base body and drives a hydraulic pressure adjusting valve opening and closing the flow path; a circuit board which controls energization of the coil; and a housing which is connected to the base body and covers the coil and the circuit board, wherein the housing includes a main body portion which is connected to the base body and is provided with an opening portion, and a lid which covers the opening portion and is attached to the main body portion, characterized in that the main body portion includes a groove portion which is formed on an outer peripheral side of the opening portion to open toward the lid, wherein the lid includes an insertion wall which extends toward the main body portion and is inserted into the groove portion, wherein a gap between the groove portion and the insertion wall is sealed by a sealing material, wherein the groove portion includes a bottom portion, an outer peripheral wall which constitutes an outer peripheral wall of the groove portion and extends from the bottom portion toward the lid, and an inner peripheral wall which constitutes an inner peripheral wall of the groove portion and extends from the bottom portion toward the lid, wherein a space for storing the sealing material is formed between the outer peripheral wall and the insertion wall and between the inner peripheral wall and the insertion wall, and wherein when a facing direction between the main body portion and the lid is a first direction, a length of the outer peripheral wall in the first direction is longer than a length of the inner peripheral wall in the first direction to suppress the sealing material from leaking to the outside of the brake fluid pressure control device by storing the sealing material between the insertion wall and the outer peripheral wall. a base body to which a flow path for a brake fluid is formed; a coil which is erected on the base body and drives a hydraulic pressure adjusting valve opening and closing the flow path; a circuit board which controls energization of the coil; and a housing which is connected to the base body and covers the coil and the circuit board, wherein the housing includes a main body portion which is connected to the base body and is provided with an opening portion, and a lid which covers the opening portion and is attached to the main body portion, characterized in that the main body portion includes a groove portion which is formed on an outer peripheral side of the opening portion to open toward the lid, wherein the lid includes an insertion wall which extends toward the main body portion and is inserted into the groove portion, wherein a gap between the groove portion and the insertion wall is sealed by a sealing material, wherein the groove portion includes a bottom portion, an outer peripheral wall which constitutes an outer peripheral wall of the groove portion and extends from the bottom portion toward the lid, and an inner peripheral wall which constitutes an inner peripheral wall of the groove portion and extends from the bottom portion toward the lid, wherein a space for storing the sealing material is formed between the outer peripheral wall and the insertion wall and between the inner peripheral wall and the insertion wall, and wherein when a facing direction between the main body portion and the lid is a first direction, a length of the outer peripheral wall in the first direction is longer than a length of the inner peripheral wall in the first direction to suppress the sealing material from leaking to the outside of the brake fluid pressure control device by storing the sealing material between the insertion wall and the outer peripheral wall.
