Description

CROSS-REFERENCE TO RELATED APPLICATION This is a continuation application of U.S. patent application Ser. No. 17/937,757, filed Oct. 3, 2022, which claims priority to Japanese Patent Application No. 2021-204617 filed on Dec. 16, 2021, incorporated herein by reference in its entirety. BACKGROUND 1. Technical Field The present disclosure relates to a guide jig. 2. Description of Related Art There has been proposed a device in which a second jig is inserted into a guide through hole of a first jig and moved toward a relevant portion (a portion at which grease needs to be supplied from a distal end portion of a greasing pipe of the second jig) until a predetermined position relationship is established between the distal end portion of the greasing pipe and the relevant portion (see Japanese Unexamined Patent Application Publication No. 2020-37949 (JP 2020-37949 A), for example). SUMMARY However, J P 2020-37949 A does not specifically describe engaging (fixing) the first jig with an engagement partner in the state of being positioned with respect to the engagement partner. There is room for consideration. The present disclosure provides a guide jig (e.g. a first jig) to be engaged (fixed) with an engagement partner in the state of being positioned with respect to the engagement partner. An aspect of the present disclosure relates to a guide jig including a guide jig body and an engagement portion. The engagement portion is provided on the guide jig body, and configured to be engaged with an engagement partner with the guide jig body positioned with respect to the engagement partner. The guide jig body includes a guide through hole provided as a through hole extending toward a relevant portion with the engagement portion engaged with the engagement partner and configured to guide a direction of insertion of an insertion portion to be inserted into the through hole and moved toward the relevant portion. The engagement portion includes at least two projecting portions. The at least two projecting portions are disposed in line in the direction of insertion. A gap between adjacent projecting portions, among the at least two projecting portions, is set to have a length corresponding to a thickness of the engagement partner. With the guide jig according to the aspect described above, it is possible to provide a guide jig (e.g. a first jig) to be engaged (fixed) with an engagement partner in the state of being positioned with respect to the engagement partner. This is because the at least two projecting portions are disposed in line in the direction of insertion and the gap between adjacent projecting portions, among the at least two projecting portions, is set to have a length corresponding to the thickness of the engagement partner. In the guide jig according to the above aspect, the engagement portion may include at least three projecting portions; the at least three projecting portions may be disposed in line in the direction of insertion; and gaps between adjacent projecting portions, among the at least three projecting portions, may be set to have different lengths. In the guide jig configured as described above, projection lengths of projecting portions positioned at both ends in the direction of insertion, among the at least three projecting portions, may be longer than a projection length of the other projecting portion. In the guide jig according to the above aspect, a gap between adjacent projecting portions, among the at least two projecting portions, may become wider toward distal ends of the projecting portions. In the guide jig configured as described above, one projecting portion of the adjacent projecting portions may be inclined with respect to the other projecting portion. In the guide jig configured as described above, the one projecting portion or the other projecting portion of the adjacent projecting portions may have been notched to abut against at least a part of the engagement partner to be inserted into the gap. With the present disclosure, it is possible to provide a guide jig (e.g. a first jig) to be engaged (fixed) with an engagement partner in the state of being positioned with respect to the engagement partner. BRIEF DESCRIPTION OF THE DRAWINGS Features, advantages, and technical and industrial significance of exemplary embodiments of the disclosure will be described below with reference to the accompanying drawings, in which like signs denote like elements, and wherein: FIG. 1 schematically illustrates a clutch release mechanism according to a first embodiment of the present disclosure; FIG. 2 schematically illustrates a greasing device according to the first embodiment; FIG. 3 is a schematic view illustrating the greasing device; FIG. 4A illustrates an example of an opening portion of a greasing pipe illustrated in FIG. 3; FIG. 4B illustrates another example of the opening portion of the greasing pipe; FIG. 5 is a plan view of the base end side of the first jig illustrated in FIG. 2; FI
